Pressure clamp connectors
Dynamic heating up
Wide voltage range
Energy saving
Clip fixing
Quick installation
These heaters are used in enclosures where damage from condensation must be prevented, or where the temperature may not fall below a minimum value. The aluminium profile heater body design has a chimney effect and distributes the heat evenly. The heaters are designed for permanent operation. Pressure clamb connectors save time and simplify installation.
