What is a Vent?

Packaged fresh air system with heat recovery

Rotating and cross flow heat exchanger

High efficiency direct driven fans

Frequency controlled

Integrated control

© Dantherm A/S

VENT R

VENT R units are particularly suitable for comfort ventilation where high efficiency (up

to 80%) and small dimensions are required. An advantage of high efficiency is that the

extra reheat coil can be left out, thus reducing the installation costs.

VENT C

VENT C units are particularly suitable for ventilation in places where the fresh air should

not get into contact with the exhaust air. Therefore cross flow heat exchangers are

especially suitable for industrial use and ventilation of humid rooms such as changing

rooms and bathrooms. The efficiency is about 55% dry / 65% wet.

CABINET CONSTRUCTION

Hot-dip galvanized self bearing cabinet with 50 mm insulation

complying with EN 1886

Internal partion walls are double skinned panels with 30 mm

insulation

Large inspection doors with hinges, handles and locks

Circular duct connections with rubber sealing gasket on and

rectangular duct connections on the inlet to provide good air

distribution through the filters and circular duct connection on the

outlet on VENT 6

Delivered in one unit with easy manoeuvring through standard

doors, but VENT 6 can be separated in three parts for easier

manoeuvring

Suitable for outdoor installation due to the sturdy construction

(requires a roof covering which is an accessory)

Base frame (adjustable feet's as accessory)

FANS / MOTORS

High efficient Ziehl Abegg plug fans with low dynamic pressure drop and factory balanced

Fan wheel is connected to the motor shaft by means of a taper lock sleeve

Frequency controlled single phase Grundfoss motors

Fans are fitted with pressure transmitters, constantly monitoring the air volume and adjusting it to the required value.

Fan/motor construction is fastened with finger screws for quickly removing the fans for inspection and cleaning.

HEAT EXCHANGERS

Non hygroscopic heat wheel with up to 80% temperature efficiency at nominal air volumeFrequency controlled motor for heat output control and free cooling Purge zone

Aluminium cross flow heat exchanger with 55% to 65% efficiency (dry/wet) at nominal air volumeModulating by pass for heat output control, free cooling and defrosting   Stainless steel condensate tray on exhaust side

FILTERS

F5 bag filters with large filter area on exhaust air side

F 7 bag filters with large filter area on fresh air side

Easy to change filters with an eccentric clamping mechanism, which gives a perfect seal (filter bypass leakage 0.5%)

ACCESSORIES

Hot water reheater coil for external duct connection, ready to mount direct to the Vent units duct connection. Electrical connection of the valve motor and frost thermostat happens by means of a cable, which is directly plugged in into the Vent unit.

Electric reheater with a step less heat output. Electrical connection of the controls and safety thermostats happens by means of a cable, which is directly plugged in into the Vent unit.

DX or cold water cooling coils for duct connection

Multi leaf dampers for duct connection

Roof cover for outdoor placing

CONTROLS

Integrated control with micro processor built in into the unit

User friendly control panel with large display and easy navigation through the setting points

Program timer with 20 steps

Communication through Lon Works, or a simple BMS communication module.

TEMPERATURE CONTROLS

Temperature control

Other methods of temperature control

Combined control of supply and room air temperature (Outdoor temperature < 15°C supply air control, > 15°C room control)Control of room air temperatureControl of supply air temperature

Constant supply air temperature without a reheating coil (VENT R)Night cooling summerOverride of preset temperature by means of an external 2-10V control signal

AIR VOLUME CONTROLS

Constant air volume control

VENT 2 Min. 400 m3/h Max. 2200 m3/h VENT 4 Min. 600 m3/h Max. 3500 m3/h VENT 6 Min. 800 m3/h Max. 5200 m3/h

Forced air volume control (Air quality sensor / humidity sensor)

Variable air volume control (Duct pressure sensor)

Compensation for dirty filters

ADDITIONAL CONTROL FUNCTIONS

Manual operation (Overrides temperature, air volume in a set time)

P.I.R sensor (If a movement is registered the unit switch over to Manual operation)

Filter guard (Not possible in VAV operation)

Motion program for the rotary heat exchanger when not in use to prevent the heat exchanger getting dirty

Communication to an BMS system or Lon Works communication (accessory)

Start signal for cooling 2-10V (water cooling coil), or ON/OFF (compressor)

Alarm functions

Start signal for hot water pump

ADVANTAGES

Both cross flow heat exchanger and rotary heat exchanger are available.

Can be used directly as an outdoor unit together with a roof kit.

Easy plug and play installation

Low internal pressure loose with high efficient fans. Therefore a low SFP figure and running costs.

User friendly large display.

All text in the control display in full words.

Step less air volume regulation.

Short delivery time (units are normally in stock).

ADVANTAGES

Advantages in comparison to block module AHU´s

Easier to find space for several smaller units then for one big one Installation costs are smaller for several small units then for one big onePlug and play between the Vent unit and the controls as both are factory tested together from Dantherm before leaving the company Ducting can be smaller and therefore cheaper and easier to hideDifferent room conditions are easier to control by several small units then one big oneUnder maintenance or malfunction only a part of the ventilation system is interruptedShort delivery time as Vent units are produced in series and are in stockPossible to modernize a building in stages
