Cupboard of magnesium metal, corrosion-evidence
Fin place: 4.5mm, 6.0mm and nine.0mm
Refrigerant: R22, R404A, R507A, and many others
Stainless metal heater, defrosting evenly
CZPT h2o receivers, more stable
Mechanically expanded pipes with Aluminum fins
Prolonged distance air throw is optional
Coils
 
Made from 9.52 ” o.d. copper tube mechanically expanded into heavy gauge aluminium plate fins will completely collared holes to make certain an efficient and long lasting bond. Fin spacings four mm, 6 mm or 8 mm.  Copper tube suction headers and distributors are individually sized to suit the actual functioning circumstances. Brazed joints are made with silver bearing copper alloy. Coils are force examined to 26 bar g, vacuum dehydrated and sealed with a dry nitrogen charge.
 
Casting:
 
Galvanised sheet steel white polyester powder coated for flush ceiling mounting or foundation mounting onto steelwork.
 
Axial Supporter
 
Axial flow, non overloading aerofoil fans with polypropylene variable pitch blades secured into diecast aluminium hubs, keyed and locked onto the motor shaft. The fans run in a shaped bell mouth orifice for effectiveness and lower noise.
 
Motors
 
Completely enclosed class F insulated metric frame, 380/420/3/50 Hz IP55.
 
DEFROST Choices
CZPT
For effective defrosting lower energy density two hundred/250V 1 ph stainless steel sheathed elements are presented in the coil and draintray.  Heaters are wired to a terminal box for 3 phase + neutral offer.
ED 1 Light duty defrost for marginal area temperatures.
ED 2 Standard duty defrost for lower temperature programs.
FP Supporter Peripheral Heaters – for purposes with room temperature beneath zero.
Reverse Cycle / Hot fuel
Coils could be circuited for reverse cycle or sizzling gasoline defrost with electrical components or scorching gas tubes in the drain pan.
HGE Hot gas coil, electric drain tray HGD Scorching gasoline coil and tray RCE Reverse cycle coil, electrical tray RCD Reverse cycle coil and tray
 
Noise Amounts
 
The noise levels said are at a length of 3 m from the unit at an angle of 45° to the horizontal in cost-free field conditions with no reflections. These are meant to be employed as a information for comparison needs. In practice the sound created will be reflected off the enclosure surfaces and might be absorbed by the item within the area. For purposes where sound levels are critical lower velocity supporters can be provided and the guidance of an acoustic professional is advised.
 
Straightforward Clear Casing
Obtainable cleanse in situation drain pan with 75 mm gap underneath coil to allow unrestricted accessibility for cleansing and inspection. Accessibility to admirer plenum.
Simple Galvanised Casing
NS4 Maritime Grade Aluminium Casing.
Stainless Metal Casing.
Insulated Drain Pans
Coils circuited for chilled h2o / glycol
 
AIR Throw
Cooler air throw is dependant on coldstore design and style, solution loading and positioning of coolers. CZPTly one metre place earlier mentioned item with no obstructions allows the air to travel considerable distances, providing that the room is tall and sufficient room is allowed to return air at reduced level and velocity. Reduced head rooms want mindful cooler siting and some means of separating discharge and return air. Cooler followers suck air again as effectively as blow.
