EKA-NIS Duct heater
Electric heaters for heating clean air in ventilation systems.
The casing is made of alu-zinc-coated steel with high temperature resistance. Heating elements made of stainless steel AISI 304. Two thermal protections and a terminal terminal were installed in the heaters. Rubber seals on connections. The heaters can be mounted horizontally or vertically. Maximum temperature of the output air 50 ° C.
All EKA duct heaters have a two-stage protection: the first stage switches on when the temperature reaches 50 ° C (the device resets automatically), the second stage switches on when the temperature reaches 100 ° C (the device is manually reset on the housing).
The EKA-NIS version has a built-in temperature controller. A 0-10V external control signal should be supplied to the regulator. The protection in the form of a thermo-contact with the manual return function is located on the device casing.
