SBE Standard Unit Coolers

详情

Evaporator Coil 
> Copper tubes 1/2, 
> Fins made of aluminium, 
> Fin spacings are *******0 mm, 
> Header inlet and outlet tube connections made of copper, 
> Admissible pressure Ps=*4 Bar. 
Casing 
> Galvanized steel sheet painted to RAL ***6 (traffic white) 
Fans 
> Low-noise axial fans with maintenance free motors, 
> Protection class IP *4/*4, single phase **0V 1~ *0Hz, 
> Constructions insulation material class F/B, admissible temperature **0°C up to **0/**5°C, 
> In case of long periods of non operation the motors must be operated every month for 2 hours, 
> The integral thermo contacts (thermistors) must be used as motor protection, 
> At low ambient temperatures and different air resistance the power consumption will increase. 
Sound Specifications 
> The sound pressure levels are calculated according to EN ****7. 
Defrosting 
> Electrical defrost as HT for (*2°C/*5°C) or LT type for (2°C/*5°C) as optional, 
> Hot gas defrosts without tubing inside of coil and drip try, without non-return valve, 
> Water defrost. 
Capacity 
> The nominal capacities calculated according to Eurovent (EN**9) standards that refer to  SC*-SC*-SC*-SC4 conditions and are valid for R**4A, 
> The refrigerating capacities refer to an air inlet temperature difference which results from the difference between cooler air inlet temperature Tr, evaporating temperature Te and ΔT = Tr - Te.
