Description

Self-limiting convection heaters

Effective and even heating of enclosures

Self-limiting (SL) heaters generate heat depending on the temperature already reached. The higher the temperature, the lower the heat output. Due to this PTC characteristic, SL heaters approach their set temperature, but never exceed it. External controllers are thus not necessary.

In contrast to heaters with constant powerself-limiting heaters (SL) have a heat source with PTC characteristics (Positive Temperature Coefficient). As the temperature rises, they increase their electrical resistance until their heating power is so low that the limit temperature of the respective temperature class cannot be exceeded.
Intertec’s lineup includes:

MICROTHERM

The most compact heating solution. Due to its slim design, this heater can be easily installed next to or between built-in devices.

MULTITHERM

The MULTITHERM is more effective when the available space is less restrictive. Although it is larger, it is more efficient.

MEGATHERM

Thanks to the compact design of the MEGATHERM, the heater can be easily installed in tight spaces.

HORIZOTHERM

This heater can be used very well underneath the installed equipment because of its horizontal construction.

VARITHERM

The VARITHERM series can provide the required heat output very well by means of differently sized heating ribs and can be designed depending on the required temperature class.

MINITHERM

The self-limiting, electric ribbed heater is used to heat the interior of housings. This type of heating is advisable when no flat surface is available for a heating block. To keep the room temperature consistent, it is recommended to use a TAE temperature controller or the TS option.

QUADRATHERM

The QUADRATHERM is characterized by being ribbed on one side and flat on the other. This makes the heater well suited for applications that use both direct heat transfer by conduction and heating of the air in the enclosure by convection
