EKA NV PTC - Electric duct heaters

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).
