DX Cooling Coils
DX evaporator cooling coils are fluid to air to fluid heat exchangers. Generally constructed from copper tubes mechanically expanded into aluminium plate fins with self spacing collars to ensure efficient heat transfer. The Refrigerant flows into the coil through the tubes from the liquid distributor into individual circuits formed with copper return bends terminating into an outlet header manifold. The heat is transferred from the air flowing over the fins and tubes into the refrigerant flowing through the tubes, as the warm air flows over the coil the low pressure refrigerant liquid evaporates and exits the coil as superheated vapour. The coil assembly is contained in a sheet metal casing with a drain tray to collect the condensate which will be produced when the air is cooled below dewpoint. Where moisture carryover over may occur due to air velocity or condensate load, moisture eliminator blades are fitted to prevent carryover into the air stream.
For low temperature applications where frosting of the coil will occur provision for defrosting can be incorporated into the coil.
Why use HC Coils?
With nearly 40 years’ manufacturing experience, HC Coils has an industry leading reputation for quality construction. We are trusted by some of the world’s leading suppliers of air conditioning and refrigeration equipment to deliver the highest quality products achievable.
We pride ourselves in sourcing raw materials from established European producers of Copper and Aluminium. Our quality control department ensures we only buy the best materials on the market, whilst also keeping prices competitive for our customers.
Coils are designed using our own in-house software, to give the optimum coil selection to meet the precise duty requirements with ideal fluid pressure drop.
We have made significant investment into our plant & machinery and production processes here at our Fareham HQ, enabling us to optimise efficiency and provide the shortest lead times in the industry.
We design, build, and configure our products in Hampshire, UK, under stringent quality controls and using state-of-the-art equipment at our purpose-built advanced manufacturing facilities.
