All our products undergo individual inspections at the end of the manufacturing line. Their dimensions, mechanical and electrical characteristics are checked according to standard NFC 79-620. In addition, each subcomponent element of our products is subjected to cold testing.

Circuit power tested by cold resistance measurements. Allowed tolerance : -5% and +10% of the nominal resistance value

Testing of insulation between live parts and the earth.The test is conducted under a direct voltage of 500 V. The minimum cold values upon release from the company are higher than 100 Megohms.

Testing of dielectric insulation between live parts and the earth.The test is conducted under an effective alternative voltage which is equal to twice the nominal voltage plus 1000 V.No warping or perforation must be found during the test.

Reading of the nominal operating temperature. (on request)The stray current and the hot dielectric rigidity can be measured on a sample.

Specific conditions of use (total power number of circuits in the assembly temperature) may lead to stray current values which require special measures.

GRADE SELECTION The most important criteria are the temperature of use, the nature of the medium and the surface flux.

St.St. 1.4541

Variety of AISI 304 stabilised with titanium to avoid chromium corbide. It is specially recom-mended for long use in the critical temperature range.

St.St. 1.4404

The addition of molybdenum (2-3%) makes it particularly resistant to chemical agents with a reducing effect. The low carbon content (or addition of titanium) gives it high resistance to intercrystalline corrosion.

St.St. 1.4828

Austenitic steel with a high chromium

St.St. 1.4876

Based on the ternary nickel/iron/chromium sys-tem and characterised by high resistance to cor-rosion in aqueous surrounding. Its high nickel content gives it effective resistance to crevice corrosion under stress due to chlorine ions. Ils high chromium content makes it resistant to oxidation and carburation at high temperatures.

St.St. 2.4858

The addition of molybdenum and cooper make highly resistance to reducing and oxidising acids, crevice corrosion under stress and pitting

These heaters are particularly suitable for heating and maintaining the temperature of large volumes or heating circulating fluids such as water, heavy fuel oil, thermal fluid, air or gas. They can be fitted on tanks, citerns, boilers and circulation reheaters and are the best electrical heating system for a range of industries such as food processing, chemicals, textiles, plastics etc.

The stainless steel or incolloy heating elements are generally hairpin-bended and are welded to the DIN/

ASA standardized flanges according to procedures which have CODAP, TÜV and ASME approval.

The watt density, ranging from 0.1 to 15 W/cm², is determined from the working parameters of the process and the exchange coefficients. For a maximum immersion length of 3300 mm, the power delivered by a flange immersion heater can reach several MW.

The electrical cabling in one or more paces gives access to several power

steps. Connection blocks and rods are used to ensure the electrical connection.

The array may be fitted with a temperature control system whereby the power and specific load are controlled by parameters such as flow rate, pressure, viscosity, temperature etc.

The bundle consists of heating elements, the active part is the 80/20 nickel chrome wire. Perfectly centered in the armoured sheath, the latter is supported by high density electrical insulation. The heating element is brazed or welded onto the mounting flange.

The bundle consist of heating cartridges or cylinder resisitances placed in thimble tubes, which means they can be changed without emptying the fluid. The thimble tubes are brazed or welded onto the mounting flange.

proTecTeD enclosure versionThe robust enclosure (6) protects people as well as the electrical connections and the temperature control equipement. To satisfy all environmental conditions, CETAL offers different type of enclosures made of PVC, aluminium, coasted steel or stainless steel depending on the atmosphere (corrosive, saline, tropical). The protection degree (IP and EX) depends on the conditions of use (industrial atmosphere, dust, explosive atmosphere).

The enclosures dimensions are determined by the number of elements, the number of junction blocks, busbars or teminal plates (7), the number and the size of the cable glands and the cross section (bending radius) of the power supply cables.

When installing, please always ensure that there is sufficient free space around the enclosures to allow the air to circulate around it.

spacersThe exchange conditions (state of laminary or turbulent flow) are modified according to shape and number of spacers (5). The hydraulic

diameter may be reduced by adding one or more tubes in the bundle.

The heating elements are welded according to certified welding procedures (QMOS) in compliance with CODAP, ASME ou TÜV

requirements… or brazed. Penetration testing and pressure tests in a hydraulic chamber guarantee the perfect quality of the welds.

Forced circulation fluid heaters are particularly suited to the heating of liquids such as water, superheated water, heavy oil, fuels, oils and ther-mal fluids and to the heating of gases under pressure such as air, steam (superheater), nitrogen, hydrogen, methane, etc.Defined specifically for each indus-trial application, these heaters consist of one or more steel or stain-less steel bodies linked hydraulically in series and/or in parallel and meet the requirements conforming to the PED European Directive.

To prevent corrosion problems rela-ted to the working fluid and operation temperature, the constituting ele-ments of the heating array are built with the appropriate stainless steel. The heating elements and the bundle spacers are designed to obtain the optimal heat exchange coefficient. The heating array, with a maximum immersion length of 3300 mm, can be equipped with temperature control devices to regulate the sheath watt density (W/cm²) as a function of parameters such as fluid flow, pres-sure, viscosity, fluid temperature, sheath skin temperature, etc…

Built in accordance with the construc-tion codes specified for the pressure and temperature in question (CODAP, ASME, TEMA, STOOMWEZEN…), these assemblies allow very high power ratings to be reached (= 2000 kW) and the controlling of circulation speeds, essential characteristics for guaranteeing an excellent thermal exchange.

The temperature measuring devices that equips our electrothermal assemblies are adpated to the method of operation selected in relation to the characteristics of the regulator (thermocouple type J-K etc). Their position (temperature of the tube-of the fluid) are deteminated by the process requirements (regulation-safety).

The regulation method choise (phase angle - wave train) depends on the application. For equipment with very high power rating, the combination of the «all or nothing» (ON/OFF) and analog solutions allows controlling of the electric power supplied over all range available.

The control/regulation cabinets enclosures display the signals and process controlled: operation - faults - temperature - set points.The later can be controlled in local or remote mode, manually or automatically, but as call or nothing or on a Modbus, FIB, Profibus DP network. Built according to the NCF 15. 000-EN 60204-I or NEMA standards, control/regulation and power cabinets or enclosures are adapted to the environmental conditions (indoor ou outdoor installation in humid, tropical, saline zones etc...) and the zone classification.

They may be fitted with ventilation, heating or cooling systems.An operation with a variable surface power density will be controlled by an analog control

signal ( thermocouple, temperature, probe). The power will be controlled by thyristor.

The electric heating of industrial processes using heating elements or assemblies, requires high-per-formance control that is properly adapted to the characteristics of the fluid to be heated (thermosensitive - variable viscosity), to the operational temperature (accuracy - stable or variable) and to the specifications

of the process (stable - slightly or highly variable flow rate/volume).

These characteristics allow the deter-mination of the system of regulation and the equipment selection for the regulation loop in order to guarantee optimum control of the dissipated energy.

Its objective is to improve protection in terms of the health and safety of workers exposed to the risk of explosive atmospheres. It stipulates technical and organisational protective measures to be taken and the documents relating to protection. The risk of explosion must be prevented and dangerous locations must be classified into zones.

Classification of hazardous location where there is a risk of explosion : it is defined that the zoning responsability lies on the shoulder of the end-user. This means he must update the zoning of its premises every time a change affecting the zoning occurs e.g. : changing its progress, changing the organisation, of its units, revamping them or putting in operation assemblies that due to their intended use bring their own zoning.

This, of course includes the new assemblies in relation to the conditions that may affect them e.g. : existing zoning, temperature condition.

To meet industrial requirements, CETAL use protective mode “e” ( EN 60079-7 increased safety) and “d” (EN 60079-1 flameproof enclosures).

Protection mode by flame proof enclosure “d”The casing (enclosure) must contain the explosion, guarantee that the ignition cannot be propagated and have at every point a temperature lower than the self-ignition temperature of the

surrounding gases and vapours.The quality of the seal (cylindrical, flat, threaded), the length of the seal and of the clearance depend on the unobstructec capacity of the enclosure and

of the gas classified in a subdivision (according to CENELEC) or in a group (according to NEC) ; their values make the propagation of the ignition impossible in the atmosphere in question.

Protection mode by increased safety “e”This mode of protection is perfectly applicable to terminal enclosures. It consists of making impossible any appearance of an ignition source (electric

arc, rise in temperature) thanks to the use of high quality insulation material, dimensioned to the leakage paths and distance in the air and to

the quality of the electric connections. It should be noted that this method of protection is suited to all gas or vapour subdivisions.

cable glanDsAs far as possible, cables and accessoiries should be used so as not to expose them to mechanical damage, corrosive or chemical influences, or the effects of heat.

Where there is a risk, appropriate measures must be taken and the proper cables must be chosen (armourded cables with mineral insulation, with reinforced cross sections to limit the admissible current.) Knowledge of the

specific installation methods and instructions for each different country is essential. Unless otherwise specified, the cable glands are selected for non-reinforced cable.

All equipment for use in explosive atmospheres made and sold by Cetal have a certificate of conformity or component certficate. Furthermore, it complies with the new ATEX European Directive.

Protection mode “de”Combination of modes of protection by explosion proof enclosure and enhanced safety « de »There are different solutions for adapting the equipment to the conditions of installation : at the connecting terminals of the heating elements and the measuring equipment are mounted in an

explosion proof casing. The eletric connection is made inside an enhanced safety casing.All the terminals are placed in an increased safety casing. The certified type temperature control devices are located in a type « d » auxiliary casing.

Manufacturing of very high performance elements is the result of the research and development carried out by CETAL during the period 1986 -1987. This allowed the widening of the application perimeters of heating by the Joule effect which until then was by traditional armoured heating elements (insulation by electrical grade magnesium oxide).

The very high performance of these ele-ments are directly connected to the control of the manufacturing process :

- Positioning of the heating wire as close as possible to the sheath whilst guaran-teeing dielectric rigidity.- Compactness of the insulation (boron ni-tride) allowing heat transfer and providing electrical insulation when hot.

Boron nitride is used as an electrical insu-lator to produce stainless steel or incolloy tubular heating elements (diameter 10, 16 or 19 mm). These one- or three-phased elements can be equipped with a core-in-tegrated thermocouple. The watt density,

which depends on the operating condi-tions (convection, conduction and radia-tion) and on the elements sheath tempe-rature, can exceed 100 W/cm²

CETAL can rely on for fifteen years of experience in the design and manu-facture of bolt heaters.

CETAL bolt heaters are specially desi-gned to deliver the maximum power to the heating part. CETAL has deve-loped Boron nitride insulation based

bolt heaters, to obtain watt densities that exceed 40 W/cm². These can be used indifferently for tightening / loo-sening of bolts, for thermal dilation of turbines, for pressure equipments, for drop-forge installations…

CETAL bolt heaters can be equipped with low-voltage connectors, cables, terminal enclosures, carrying han-dles. CETAL bolt heaters’ technology allows heating to be achieved in a few minutes, thus reducing down-time of pressure equipments and installa-tions considerably.
