Defrosting elements

Used to prevent ice formation and freezing


Proper work of evaporation unit in cooling houses is impossible without heating elements for defrosting of evaporator, evaporator tray, drainage pipes and other parts of the system. Tubular heating elements are the most common solution for defrosting of evaporator and evaporator tray. Tubular heater is equiped with cable with thicker silicone insulation and waterproof connection made from thermo shrinking sleeve. Waterproof connection is essential due to really harsh working conditions - ice, water, thermal shocks etc. Elektrotermija produce heating elements for compressors, fans too and we can offer complete range of products for defrosting/heating for cooling houses.
