Heat Transfer UnitsElectrically heated thermal oil units are especially used to heat and control the temperature of a consumer at high operating temperatures and low pressures. Our electrical heaters are used in these systems for which we design the surface load of the heating elements in accordance with the operating conditions.

Heat Transfer

IR ElementsIR elements are used for radiant heating, primarily in the plastics, paint, food, textile and workshop industries.

IR elements are produced in ceramic materials, quartz glass, and quartz glass with halogen. Elements in ceramic material or quartz glass emit infra-red radiation of long to medium wavelength at a working temperature between 150° - 760°C. Elements in quartz glass with halogen emit infra-red radiation of short wavelength and provide a working temperature up to 2,400°C. These elements can be used in environments with a vacuum, or where there is air movement. Infra-red radiation provides fast and effective heating at low investment cost and is especially suitable where brief heating at intervals is needed.

Used for e.g. plastic moulding; drying paint and print; sterilizing; glueing; silk screen printing; as terrace heaters.


ATEX

General InformationIn the chemical and process industry, as well as in the manufac-turing industry and the offshore sector, various media are produced, manufactured, and stored in potentially explosive areas, thereby requiring special explosion proof equipment.

Our explosion proof solutions are manufactured in accordance with ATEX, an EU directive relating to electrical and mechanical equipment for use in potentially explosive areas.

We produce electric heating solutions for solid and liquid ubstances as well as for gases, and these may be supplied complete with control cabinets. Among other things, we produce:

• immersion heaters for liquid substances and gases• circulation pre-heaters for liquid substances and gases• gas pre-heaters for industrial gases such as hydrogen, CO2

and nitrogen• air pre-heaters / re-heaters• finned tube heaters• various industrial heating solutions• junction boxes, thermostats, electronic temperature

regulators and controllers for duct heaters

The term of “explosive atmosphere” is defined as a mix of inflammable substances - in the form of gases, vapour, mist or dust - which may lead to fire spreading to the un-burnt mix following ignition. Atmospheric conditions are normally defined as -20°C to +40°C, pressure 0.8 - 1.1 bar.We produce equipment for ATEX areas, with different temperature and pressure on the media and for all temperature classes.

BASIC ELEMENTEx e II heating elementOne of the basic elements of explosion proof equipment is the tubular heating element. This heating element comprises a nickel chrome resistance thread surrounded by a metal cap and insulated with compact magnesium oxide. These elements can be bent to achieve optimum utilization.

The standard sizes of the elements are Ø8.5mm, Ø10.2mm, Ø12.7mm and Ø16mm.

Cover material: AISI 304/316/321/310, SMO254, Incoloy 800/825, Inconel 600, titanium and copper. Other materials on agreement.

We have developed heating element with enhanced safety, Ex e II, in accordance with EN 60079-0 and EN 60079-7. This element forms a basis for equipment with enhanced safety; this means that special rules have been implemented with regard to the design (in order to create an opportunity for enhanced safety) in order to prevent high surface temperatures as well as sparks in the inner or outer electrical parts. These Ex e II elements can be built into a junction box with a minimum degree of protection of IP54 fitted with Ex e terminals.

Pressure proof thermostats and thermo elements fitted in a junction box are used for maximum temperature protection and control. All coupling units in the junction box must be of pressure proof design.
