ECO Commercial Evaporators
CTE Ceiling Evaporators
(TÜV Approved to ENV 328)
The CTE range of unit coolers is suitable for installation in cold rooms for the preservation of fresh or frozen products.
The compact size of the unit allows to make maximum use of the storage space of the cold room in which it is
installed.
The entire range is equipped with high efficiency coils made from special profile aluminium fins and inner grooved
copper tube, suitable for the new generation refrigerants.
According to the room temperature the range is divided as follows:
CTE H3 for higher temperatures
(> +2 °C) with 3,5 mm fin spacing;
CTE H4 for higher temperatures
(> +2 °C) with 4,0 mm fin spacing;
CTE M6 for medium temperatures
(> -15 °C) with 6,0 mm fin spacing, electric defrost version (ED) is recommended;
CTE L8 for lower temperatures
(> -35 °C) with 8,5 mm fin spacing, equipped with electric defrost (ED).
This range employs three types of standard fan motors:
A) diameter 250 mm, shaded pole single-phase 230V/1/50-60 Hz with fibre-glass charged polyamide fan guards.
B) 315 mm diameter, external rotor single-phase 230V/1/50-60 Hz with built-in electric capacitor and epoxy coated steel fan guard.
C) 350 mm diameter, external rotor single-phase 230V/1/50-60 Hz with built-in electric capacitor and epoxy coated steel fan guard.
D) 500mm diameter, external rotor three-phase 400V/3/50-60Hz with epoxy coated steel fan guard.
The standard fan motors employed have the following features:
IP 44 protection grade; (IP54 for 500mm)
class B insulation; (F for 350mm - 500mm)
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/3/50-60Hz 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.
