EPO-V series electric heaters are supplied in two ranges – circular haters with capacities between 0.9 kW and 12 kW
and rectangular heaters with capacities between 15.0 kW and 54.0 kW.
As standard, both ranges feature heating radiators, power switching elements with so-called zero voltage switching
(SSR), a built-in return safety thermostat for switching off the control circuit in the case when air temperature exceeds
+70 ° C, a built-in manual safety thermostat for swi tching off the control circuit in the case when air temperature exceeds
+120 ° C (manual reset), and control electronics all owing to switch on the electric heater via a 10-24 V DC control signal.
