Flat electric heating cables EHC-F
Flat electric heating cables EHC-F
These heating cables are designed for outer heating of press dies and flat surfaces.
Electric heater consists of a heating element and a case. Case is made of 12Cr18Ni10T steel.
Heating element is made from 2 or 3 mm diameter heating cable KNMCNH-N. Cable conductor - Cr20Ni80 alloy, cable sheath - stainless steel 12Cr18Ni10T.
For AC or DC main connection electric heaters are equipped on default with current-carrying wires 250 mm long, made of PRKA wire in high-temperature insulation (up to 180°С). Lead length can be increased.
On customer's request electric heater can be equipped with M5 threaded contact bar. At the time of order this request should be specified as version 2
Operating and outer surface temperature of electric heater does not exceed 600°С – in running condition under heat removal with natural air convection.
Operating voltage:220 V specific heat flow rate:3-5 W/cm2
