1. General

TAEevo Tech is an air cooled liquid chiller, designed for industrial use and for installation in an external environment. A broad range of options available in product configuration and accessories in kit form, complete the already generous standard equipment and allow this machine to meet the majority of requirements of industrial applications. TAEevo Tech is therefore the solution for all applications that require high performance, reliability, continuity of operation and reduced management costs.

All the TAEevo Tech models are equipped with a high efficiency finned coil evaporator immersed in a hydraulic storage tank. Thanks to the technology of this evaporator the TAEevo Tech ensures reliable operation in particularly demanding applications and also with liquids containing impurities. The standard hydraulic storage tank also assures optimum precision in the control of temperature even

in the presence of highly variable thermal loads from the user and simplifies installation.

The TAEevo Tech units are equipped with a finned coil condenser, axial fans and scroll compressors installed on a refrigeration circuit (mod. 015-401) and two refrigeration circuits (mod. 402-802). The refrigerant used is R410A.Management of the TAEevo Tech is provided by an iCHiLL 208CX parametric microprocessor control capable of managing all the main functions, including outlet water temperature control, alarms and external interface.

The TAEevo Tech units are available in standard version with power supply 460/3/60 Hz. The degree of electrical protection is NEMA Type 1 and IP44 for the mod. 015-020, IP54 for the mod.031-802.

4. Advantages derived from the use of a storage tank

In a refrigeration system designed for use in an industrial process the user load may present significant and sudden variations, or working conditions that are very different from nominal conditions for long periods. Consequently the chiller supplying the plant is frequently required to operate at maximum capacity (in the proximity of its operating limits) or alternatively with periods subject to frequent ON/OFF cycles. This type of working is detrimental to the lifetime of compressors and often results in significant fluctuations of the chilled water temperature - clearly undesirable both from the energy efficiency standpoint and also in relation to the requirements of the process.The benefits deriving from the use of the storage tank present on all the TAEevo Tech units as standard can be summarised as follows:

• The units offer a reservoir of water at the preset temperature for the process to be controlled: in this manner the “energy stored” in the tank is able to compensate for the imbalances caused by sudden changes in load demand from the user.

• Operation of compressors in highly stable conditions: in this case the chiller can run with almost unvarying inlet temperature irrespective of surrounding conditions. Together with a constant water flow rate,this is a primary condition in order to ensure the maximum lifetime of the compressors.

• Reduction of the frequency of peaks and guarantee of sufficient duration of each period of running and each period of stopping of the compressors.

5. Testing

All units are tested in a test chamber in order to check correct operation. The main checks performed are as follows:• the correct instalment of all components and the absence of

refrigerant leaks;• electrical safety tests as prescribed by EN60204-1;• correct operation of microprocessor and correct values of all the

operating parameters;

• the temperature probes and pressure transducers;At the time of installation the units require exclusively electrical and hydraulic connections, thus maximising reliability levels. It is always advisable to install a filter on the unit inlet.

6. Construction configurations

By combining the configurations described below with the accessories available as sales kits the units can be customised to meet a very broad range of plant requirements.WARNING: when configuring the unit it should be remembered that not all combinations are possible. Always consult the PERFORMANCE AND TECHNICAL DATA section for the model in question or contact us.

7. Compressors

Refrigerant compressors with orbiting scrolls, 2-pole electric motor, mounted on rubber antivibration dampers. These compressors feature protection against overheating, excessive currents and against temperature values that are too high for the exhaust gases.The crankcase heater standard is automatically supplied when the unit stops (the chiller must be switched on), preventing dilution of the oil by the refrigerant when the compressor is shut down, thus ensuring proper lubrication of the mechanical components even at low temperature environment.Thanks to the low weight of the rotating components and the absence of suction and discharge valves, the scroll compressors offer a

series of benefits: higher energy efficiency, reduced pressure drops on the suction side, significantly lower noise level, reduced vibration on the delivery side, high resistance to possible liquid hammering. The compressors are installed within a compartment separate from the condensing vane, allowing maintenance tasks even when the machine is running.The models 201 - 802 use two compressors connected in parallel for each circuit increasing performance with partial loads and thus maximise the ESEER Seasonal Energy Efficiency Ratio. This solution, using the “unloading” function, also allows the starting up the system, and the operation of the machine, even in conditions very different from the nominal ones.

8. Evaporator

High-efficiency finned coil exchanger made with copper pipes and aluminium fins, shoulders and cabinet made of galvanised steel. Installed inside the water storage tank, the evaporator cools the process fluid that flows in contact with the finned surface, exchanging heat with the refrigerant fluid evaporating inside the tubes. This particular technical solution allows TAEevo Tech to operate with high flow rates and reduced pressure drops, ensuring a high level of reliability in heavy industrial applications and also with liquids containing impurities.

The antifreeze function of the microprocessor controls the outlet temperature of the water while protecting the evaporator from the danger of freezing. A level sensor inside of the tank protects the chiller from the lack of process fluid. All evaporators installed on the TAEevo Tech chillers can work with antifreeze solutions and, generally, with all other liquids that are compatible with the materials utilised in the hydraulic circuit (refer to the list of materials in contact with process fluids).

9. Condensing coil

Finned coil heat exchanger consisting of tubes and the manifolds in copper, corrugated fins in aluminium, and shoulders in galvanized sheet metal. These coils are sized and designed utilising the latest computerised design technology, making it possible to achieve very high EER efficiency values. Thanks to the positioning on only one

side of the machine, installation is also facilitated when the spaces available are restricted (example: close to a wall). From mod. 031 the condenser is protected by removable metal filters to facilitate cleaning procedures (in mod. 015-020) protection is provided by a panel grid.

10. Fans

Mod. 015-020 are provided with axial fans equipped with painted sickle-shaped galvanized steel sheet blades that are directly connected to the electric motor (IP44). Mod. 031-802 are provided with axial fans made in die-cast aluminium, sickle-shaped blades in aluminium or galvanized steel sheet covered with polypropylene and electric motor IP54. All the fans’ motors are provided with built-in thermal circuit breakers.

The fans are statically and dynamically balanced, equipped with external safety grilles.The motors feature 4 or 6-poles with external rotor to maximize the energy efficiency, and are protected with a chain of thermistors.Standard fan control for models 015-401 is ON/OFF type managed by pressure switches. In models 402-802 control is in step mode with pressure transducer.

11. Refrigeration circuit

The refrigeration circuit comprises:• Mechanical thermostatic expansion valve with external

equalization: located at the inlet of the evaporator, it controls the flow of refrigerant according to the thermal load. This valve optimises compressor performance,ensuring sufficient superheating of the gas on the suction side in all operating conditions.

• Filter-dryer hygroscopic molecular sieves: it retains the impurities and any traces of moisture present in the refrigeration circuit.

• Liquid refrigerant and humidity flow indicator: installed on the liquid line, it enables checking of the correct charge of refrigerant gas (presence of bubbles) and for any moisture in the refrigerant circuit.

• High and low pressure refrigerant pressure gauges: available from model 031, they are installed on the front panel.

• HP High pressure and LP low pressure refrigerant pressure switches.

• PV fan pressure switch: for ON/OFF control of the fans (Mod. 015-401).

• Pressure transducer: mod. 402-802. • Schrader service valves.

All of the brazed welded joints are made with silver alloy and the cold pipes are insulated to prevent the condensation of moisture.

12. Structure and casingAll models have a structure with the compressor compartment separate both from the compartment where the tank and the condensing coil are located and from the electrical cabinet, thereby simplifying maintenance operations. Units from model 015 to 161 are equipped with a fully enclosed cabinet with structural panels and pump installed in the compressors compartment. The models 201-802 are equipped with a fully enclosed cabinet, plinth composed of longitudinal beams and crossmembers,and uprights to support

the outer panelling. The plinth, uprights and all outer panels and/or enclosure panels are made of galvanized carbon steel sheet and assembled by means of galvanized steel rivets or stainless steel metric screws to facilitate removal. All panels undergo a phosphor degreasing phase followed by epoxy polyester power coating. The plinth and the coolant pressure gauge panel are in RAL 5013 blue colour, while the rest of the structure and panels are in RAL 7035 light grey.

13. Hydraulic group

INERTIAL STORAGE TANK All models are equipped with a cylindrical inertial storage tank (containing the evaporator) externally insulated by an insulating and anti-condensation layer. Sized for operation in closed hydraulic circuits and with maximum pressure of 6 barg, the storage tank

can also be used in open hydraulic circuits if equipped with the tank filling kit. The standard tank is in carbon steel while in the Non Ferrous version the AISI 304 stainless steel is used. The tank is equipped with a drain valve so that it can be emptied and with a bleed valve to vent air during the process of filling the hydraulic circuit.

HYDRAULIC BY-PASSAll TAEevo Tech are equipped with an internal by-pass between the hydraulic outlet and inlet connections.In case of an incorrect closing of inlet/outlet connections, the hydraulic by-pass allows the machine and the pump to preserve their integrity, ensuring a minimum fluid flow necessary for both the anti-freeze alarm and the pump circuit breaker interventions.Warning: the by-pass has been designed only for preserving the integrity of the machine if the shut-off valves fail to close. The by-pass operation with continuous cycles for extended periods is strictly forbidden.

LEVEL SENSORConductive-type level sensor. If the process fluid within the storage tank is insufficient, the operation of the machine is blocked.

PUMPSThe pumps are centrifugal type with motors in IE2/IE3 class according to the models (International Regulation IEC 60034-30) with seals made of silicon carbide / silicon carbide / EPDM material. The pumps are

available in two different configurations: pump P3 with nominal pressure head 43 psig and pump P5 with nominal pressure head 72 psig.Pump materials in contact with process water:• pump P3: fully stainless steel up to mod. 251; for the remaining

models, the pump body is made of cast iron;• pump P5: fully stainless steel up to mod. 161; for the remaining

models, the pump body is made of cast iron;• pump P3 and P5 pump completely in stainless steel for the Non

Ferrous version (see “Non Ferrous Versions) for pressure circuits.

BLEED VALVEBleed valve: installed on the top of the cylindrical tank, the bleed valve is used to vent any air pockets in the tank.

WATER PRESSURE GAUGE A water pressure gauge on the unit’s rear panel indicates the water pressure at the unit outlet and plant filling pressure (with pump stopped).

14. Electrical panel

The electrical cabinet is designed and wired in compliance with the directive UL 508A.It is composed of an enclosure accommodating all the components secured to a mounting plate, with a hinged door having a perimeter seal mounted to the cabinet structure. For the mod. 015-020 it is composed by a cover panel with a perimeter seal. The unit’s controller is mounted on the door and it is protected by an openable transparent polycarbonate cover; the door is also equipped with the main disconnect switch with safety door lock (door cannot be opened until the electrical cabinet power has been disconnected). The electrical cabinet utilises components sourced from premium

manufacturers and ensures a level of weather protection that is commensurate with outdoor installation of the chiller (protection rating IP54) NEMA Type 1. The power section includes automatic thermal-magnetic cut-outs for the protection of power devices such as compressors, fans and centrifugal pumps, a series of contactors and a phase monitor for protection of the unit from the absence of phase and from incorrect phase sequence. The control section includes the transformer feeding the auxiliaries and the microprocessor circuit boards. A voltage-free general alarm contact plus fitting for remote ON/OFF are also available.

15. Control and safety devices

High pressure transducers: standard for the mod. 402-802. The pressure transducers measure the compressor discharge pressure with the resulting signal utilised by the electronic controller for the following functions: high pressure measurement and alarms, unloading for high pressure and fans step control.Temperature probes: installed on the hydraulic circuit, they measure the temperature values of: evaporator outlet water (antifreeze function), storage tank outlet water (temperature control function).

External air temperature probe available as standard.High and low pressure switches with automatic reset: they are installed on the refrigerant circuit high/low pressure side, respectively; they stop the compressor if anomalous working pressures are detected.Fans pressure switch: used for ON/OFF control of the axial fans.Conductive point level sensor: installed in the tank where it is used to shutdown the unit if an insufficient water level is detected

SELECTION GUIDE

Selection of a chiller is performed by means of the tables given in the “Selection guide” and by means of the Data Tables relative to eachmodel. For correct selection of a chiller it is necessary:

1) Ensure that the operating limits specified in the “Working limits” table are complied with”.

2) Ensure that the flow rate of water to be cooled is between the flow values specified in the “General Data” table of each unit; excessively low flow rates will result in laminar flow and, consequently, a risk offreezing and poor temperature control; in contrast, excessively high flow rates lead to excessive load drops and possible bursting ofevaporator piping.

3) Add ethylene glycol or other antifreeze liquids when using the chiller at water outlet temperatures below +41 °F; consult the “Water and ethylene glycol solutions” table to find the quantity

of ethylene glycol required and to assess the reduction in cooling duty, the increase in compressor power input, and the increase in evaporator pressure drops due to the presence of ethylene glycol.

4) If TAEevo Tech models are installed at altitudes in excess of 1640 ft, assess the reduction of cooling performance and the increase in compressor power input values by means of the coefficients given in the”Condenser corrective coefficients” table.

5) If the temperature difference between the evaporator water inlet andoutlet differs by 10 °F, correct the cooling capacity and power input utilising the“ΔT corrective coefficients ≠ 10 °F” tables.

INSTALLATION GUIDE

The chillers must be installed in compliance with the following indications:

a) The units must be installed horizontally to ensure correct return of oil to the compressors.

b) Ensure that the clearances prescribed in the catalogue are observed.

c) Position the unit in such a way to minimise the effects of noise emissions, vibration, etc. Specifically, ensure that the units are installed as far as possible from areas in which noise emissions could result in disturbance; in this context do not install the chiller under windows or between two residential units. Vibration transmitted to ground must be reduced by the use of antivibration devices mounted beneath the unit, flexible couplings on the water piping connections and on the trunking containing the electrical power feeding cables.

d) Always hook up the electrical connection of the unit with reference to the wiring diagram supplied with it.

e) Make the hydraulic connections installing the following: - antivibration connections; - shut-off valves (gate valves) to isolate the unit from the hydraulic

circuit; - test points on the inlet and outlet piping for temperature

measurements, to obtain a direct indication of working temperatures; - air venting valves at the highest points of the circuit; - drain valves at the lowest points of the circuit; - pump and expansion vessel (closed circuit) if not already supplied

on the unit; - flow switch (to be supplied by the customer); - strainer (0,02/0,03 inch) at unit inlet to protect the exchanger from

any metal chips or debris in the piping.

f) Install suitable wind screens protecting the condensing coils if the chiller is required to operate with ambient temperatures below 32 °F and if it is envisaged that the condensing coils could be subject to wind velocities greater than 6.6 ft/s.

g) If the application requires cooling capacities greater than the maximum available with a single unit, several chillers can be hydraulically connected in parallel. In this case it is necessary that the units are identical to avoid water flow rates imbalance.

h) It is essential to ensure an adequate volume of air on the intake and delivery sides of the condensing coils. It is also important to avoid recirculation of air between the intake and delivery sides of fans to avoid a reduction of performance or even a shut-down of normal operation. When using several chillers connected in parallel with the condensing coils located face to face on adjacent units, it is essential to maintain sufficient distance between the units. For the minimum distance values refer to the Technical Catalogue.

i) If it is necessary to process water flow rates that are greater than the maximum permissible, it is advisable to set up a by-pass between the chiller inlet and outlet.

l) If it is necessary to process water flow rates that are lower than the minimum permissible, it is advisable to set up a by-pass between the chiller outlet and inlet.

m) Ensure that all the air is bled out of the hydraulic circuit.

n) Always drain the hydraulic circuit during winter shutdowns; alternatively ensure that the circuit is filled with a suitable antifreeze solution. We also recommend running the pumps during brief winter shutdowns and fitting additional electric heaters on the hydraulic circuit piping.
