When is a door case-heater necessary?

A door case-heater prevents the freezing on of the door seal. So it allows to enter climate chambers, rheumatism cells, deep freeze cells, deep freeze rooms and cold stores unabstracted. As frame-heaters, silicone- and PTFE-isolated heating pipes are mainly used. So the Hemstedt-products cover a temperature from -100°C to +200°C (with PTFE-isolation) (above 0°C only permitted with a temperature-cutout = overheat control).
