The heating chamber is closed with a header which a heater, working temperature control, sensor case, and electric connection are fixed to. The header is covered with a plastic lid. The sealing applied assures protection against moisture on IP44 level for the heater and IP20 for the adjustable thermostat.

The heater has two connection bushings with ¾” pipe thread which connection terminals with the external diameter matching the hose of 16, 17, 18 or 20 mm or a terminal with ¾” thread which allows connecting the steel corrugated hose with the diameter of 20 mm are screwed to. It is equipped in an electric connection realized via OWY 3×1.5 cable with the length of 3 running metres.
