Ventmatika EKA - Descrip on

Descripon
Electrical duct heaters EKA are designed to heat fresh air in venlaon systems. Casing (EKA protecon class IP
44, except EKA Type NV which protecon class IP 30) is made from Aluzinc coated steel which is high temperature
proof and with rubber seals for duct connecon. Tube of heang element is made from stainless steel AISI 304.
There are 2 protecon thermostats and screw terminals for easy connecon installed in the heaters.
Heaters can be installed horizontally with the electrical connecon box facing upwards or sideways and
vercally (only if the air flow direcon upwards). Heaters can't be installed in explosive and aggressive substances
environment. Heaters can be used only for the clean air heang or preheang. Heaters intended only for inside
installaon. If heater is installed in such way that can be accidental contact with heang elements, protecve grill
must be installed. The air velocity in the duct of the heater must be 1,5 m/s minimum. The maximum temperature
of the output is 50 °C.
Heaters EKA with integrated temperature controller EKR-K… (See Fig. 1) can be controlled in five different ways
depending on control type:
Type EKA NV – potenometer on the lid of the heater (See page 11).
Type EKA NI – external wired remote setpoint knob (TR5K) for temperature control (See page 11).
Type EKA NIS – external wired remote 0…10V signal for temperature control (See page 12).
Type EKA ESKM – external wired remote PWM (ON/OFF: ON(6…24)VDC) signal for temp. control
Electrical duct heaters EKA with integrated temperature controller EKR-K… works by PID regulator. That enable
fine temperature control. Controller EKR-K… controls load by Triacs without moving parts, which causes no-noise
commutaon.
