Intertec’s series of slimline vertically mounted electric heaters protect sensitive outdoor equipment against low temperatures in hazardous areas such as chemical, oil and gas plants.

Available in five variants with output powers from 200 to 600W, the finned heaters are compact, high-efficiency blocks with profiles of 60mm – making them suitable for mounting adjacent to panels inside enclosures.

This versatile design typically makes it simple for engineers to use when configuring protective enclosures, cabinets and shelters for field-based equipment.

The new CP Megatherm heaters are approved to IEC and other worldwide explosion-proof standards such as Atex, CSA, UL and GOST.

This makes it possible for one heater or enclosure configuration to be used anywhere in the world – greatly reducing design, system building and maintenance costs.

The flat rectangular shape of the CP Megatherm reprises Intertec’s original design concept for explosion-proof heaters.

The new heater exploits advances in insulation and sealing materials to deliver more power in a smaller form factor than the original product, as well as more application versatility across different temperature classes.

The heaters use the Ex d (flameproof) protection principle and are available for the commonly required T3 or T4 temperature classes, which restrict surface temperatures to a maximum of 200 or 135C respectively.

A temperature indicator strip is also attached to show potential, problems such as incorrect installation or misapplication, at an early stage.

CP Megatherm heaters are supplied with a thermostat to limit the ambient temperature in an enclosure and protect against freezing and condensation.

This thermostat is located in the electrical connection cable – a patented design that maintains the heater’s compactness and simplifies installation.

If more precise temperature regulation is required, Intertec can supply heaters with an optional temperature controller.

CP Megatherm heaters’ low-profile designs typically allow the heating element to be positioned in close proximity to any process equipment that requires protection.

The heater body is fabricated from seawater-proof aluminium, with a black anodised finish.

Additionally, the heaters are protected against ingress to IP68, so they are highly reliable, even in corrosive atmospheres such as hydrogen sulphide or ammonia.
