Technical Specifications
Blast Freezing Air Cooler ;
Characteristics Of Casing:
Optionally, manufactured with stainless casing
- Hot-dip galvanized sheet
- Anti-rust and permanent electrostatic powder paint (RAL 7047)
- Hinged drain tray,
- Easily removed side covers by loosening the connection screw
- Ceiling mounting brackets
Characteristics Of Heaters:
E2 type heating resistor is used for lower than 0°C room temperature. The resistors are mounted on the coil and on the drain tray.
In blast freezers, E3 type heating resistors are used as standard. Also heating resistors are mounted on the fan cage together with the cooling coil and the drain tray.
- E2: Coil + drain tray electrical defrost
