Control systems & components for industrial heating, ventilation, air conditioning

Electric duct heaters EKA PTC/PS

Electric duct heaters EKA...NV PTC are designed to heat clean air in ventilation systems and react to air flow in the duct. Air flow through the heater can't be less than 1,5 m/s. If there is an air flow in the duct, PTC sensor gives a signal, which allows to begin heating, depending on heating value set on the heater. If there is no air flow through the heater, heating is blocked (regardless from heating need).

If there is no air flow through the heater, heating is blocked (regardless from heating need). Electric duct heaters EKA ...NV PTC with integrated temperature control contains temperature regulator which works by algorithm impulse/pause, that enables fine temperature control. Regulator controls load by triacs without moving parts, witch causes no-noise commutation. Potentiometer is used to set temperature. Manual thermal contact restoration button and temperature set point are located on the case of a heater. The duct temperature sensor is included. Heater is powered from the mains and contactor runs heating via differential pressure switch PS. Pressure switch PS runs when pressure difference occurs in the duct.

All electric duct heaters EKA ...NV PTC/PS have built in controllers with default setpoint from -10°C till +50°C, but our customers can choose right setpoint according to their needs:

 *Temperature setpoint
-40°C till -10°C
 -20°C till -5°C
 0°C till +30°C
 -10°C till 0°C
 -5°C till 0°C

*Please, inform what setpoint do you need before production.
