  • Insulated PTC Element for commercial e-mobility, mass transit and industrial HVAC
  • High Voltage (AC/DC)
  • High Power
  • IP65


The ATMOS series elements are heavy duty air heating elements, designed for commercial vehicles (e.g. buses) and other industrial applications. The elements employ innovative technologies to provide a high heating power at high voltage, while being rated to IP65 (with DBK harness system).

In addition, the elements are engineered for long lifetime under the most demanding conditions. This type of heater features a wide height to width ratio, height 90mm x width 250 – 650mm (customizable). The element is designed with a degree of flexibility in its structure, and should be built into a rigid mounting frame. A customized harness can be provided e.g. with automotive style wiring, and optional rubber seals for a fully IP65 rated solution.

Customizable assemblies including stainless steel mounting frame and harness can be provided. Banks of elements can be used, meeting a wide variety of installed sizes and powers, e.g. 12kW, 24kW.
