Description
CASING
Assembling of white prepainted galvanized steel panels, giving a good corrosion protection, the casing is especially designed for easy access for maintenance and cleaning :
- Intermediate drip tray limiting condensation under the main drain pan.
- Swivel doors and drain pans providing an easy access to the different components of the heat exchanger (coil, connections, defrost heaters, expansion valves, …).
- Single water drainage Ø 2″”.
- Fan motors mounted on hinges.
COILS
- Finned coils with copper tubes and aluminium fins especially designed for evaporation process, providing an increased heat transfer coefficient.”
- Standard fin spacing : 6.3mm.
- Factory mounted diaphragm liquid distributors with a DP of 2 to 2.5 bars.
- As a standard the coolers are optimised for R404A/R507.
- Please consult us for other refrigerants.
- Schrader valve fitted on the suction header enabling to measure the evaporating pressure and to check the running.
- parameters of the cooler (direct expansion). Delivered under dry air pressure (direct expansion).”.
VENTILATION MOTORS
- Axial fans with two speed motor, “star / delta” type :
DUO60 – Ø 650mm
6PH / 6PL
8PH / 8PL
Motors : factory wired. - Temperature range : -30°C and +45°C.
- Voltage :
– 3 phase supply 400V(+7%/-10%)/~3/50Hz for PH and PL models.
– 3 phase supply 230V(+7%/-10%)/~3/50Hz for PL models. - Protection IP55 (CEI 34-5). Drain-hole and shaft seal with nylon gaskets.
- Class F (CEI 85 and CEI 34-1).
- Maximum frequency of starting : 20 starts per hour
- (consult installation and operation manual).”
PROPELLERS
The fans enable a significant sound reduction, while keeping high airflow performances. This is the result of :- a balanced distribution of the air load on the fan blades.
- an optimisation of the angles of incidence avoiding fan turbulence at the suction.
- an optimised fan profile allowing a low drag coefficient.
- a dynamic balancing of the fan in two plans”
