Chamber bell DH21 heater

Divex product motif logo.jpg

JFD's world-renowned Kinergetics chamber bell DH21 heater provides an efficient means of heating diving chambers or bells.

The Kinergetics chamber bell DH21 heater is one of the most widely recognised hyperbaric environmental products in the diving industry. The heater coil assembly is mounted to the same blower unit as is used on the DH21 scrubber. As chamber hot water passes through the coil, the surrounding air is warmed before being blown and recirculated in to the chamber or bell’s atmosphere.

Manufactured from stainless steel, the DH21 has a robust design with an excellent resistance to corrosion.
