Chiller Tubes
Application of tubes in a large Chiller
Chiller tubes are being used in water chillers for industrial process cooling applications and large air-conditioning units. Large chillers with a high cooling capacity can be found in high rises, airports, shopping malls, hospitals, etc.
The surface of a chiller tube is enhanced on the outside and on the inside to increase the heat transfer between water and refrigerant in the evaporator and condenser. The enhancing process is similar to a roll-forming process. The inside surface looks like a rifled surface; the outside surface contains special microstructures. The increase of the heat transfer performance of this special type of tubing goes beyond the increase in surface area.
The Wheeling Plant manufactures chiller tubes in copper C12200 in ¾″ and 1″ outer diameter with various wall thicknesses. Tubes for high-pressure and low-pressure refrigerants are available. For other fin tubes please visit www.wieland.com
Wieland tubes are designated as GEWA-B (boiling tube) or GEWA-C (condensing tube). GEWA is short for the German word "GEWALZT" or "rolled".
Our in-house laboratory can provide exact heat transfer performance data. An increased heat transfer performance of the chiller tubes allows our customers in the air-conditioning and refrigeration industry to either reduce the size of a shell and tube heat exchanger or instead increase its performance.
