ECO Commercial Evaporators
STE Ceiling Coolers
The STE range is specifically designed for applications in cold rooms with limited height for the preservation of fresh
or frozen products.
According to the room temperature the range is divided into two series:
STE H3 for higher temperatures (> +2 °C) with 3,5 mm fin spacing;
STE L7 for lower temperatures (>-25 °C) with 7 mm fin spacing and electric defrost.
Standard fan motors employed have the following features:
315 mm diameter external rotor single phase 230V/1/50-60Hz with built-in electric capacitor and epoxy coated steel
fan guard;
IP 44 protection grade;
class B insulation;
internal thermal contact protection;
operating temp. -35 °C - +40 °C.
The versions with standard electric defrost (ED) are equipped with stainless steel heaters with vulcanised terminals
preset for 400V/3/50-60 Hz connection.
The electric parts and casework are connected to a grounding terminal, the wiring of the motors and heaters is
carried out in separate IP 54 protection grade junction boxes.
