Let us help with your heating and cooling projects.

Wieland Onda Heat Transfer Solutions – Shell and Tube Heat Exchangers

The main applications of our dry-expansion exchangers are the cooling of water, glycol or brine solutions in refrigeration plants as well as the hot water production in heat pumps. Wieland Onda cater for the majority of HCFC’s and HFCs refrigerants and certain models are optimized for certain refrigerants i.e R134a chiller applications. The Wieland ONDA shell & tube evaporators have a cooling capacity range from 15kw to 1400 kW with options on 1 to 4 refrigerant circuits. The water connections standard position is vertical, but on request can be placed horizontally, at right (DX) or left (SX) side when facing the refrigerant header. Certain models have the advantage that the entire tube bundle can be removed for cleaning or for easy replacement.

Manufacture of a Heat Exchanger

MATERIALS The quality of the materials used to manufacture Wieland ONDA exchangers satisfy the requirements of the European pressure vessels Codes. The standard type construction of the shell & tube exchangers consists of following materials carbon steel for header, tube sheet, shell, refrigerant and water connections; copper tubes; brass or carbon steel for the baffles; asbestos free gaskets; bolts made of alloys steel. On request, other materials compatible with our production facilities can be used including Stainless steel or Titanium for the tubes and stainless steel for the shell.

Shell & Tubes General

ACCESSORIES
We can offer loose or welded mounting supports, waterside counter flanges, vitraulic connections and insulation. 
TEST, VESSEL CODES, WORKING LIMITS: Each heat exchanger undergoes a pressure test on the refrigeration side (also a differential test when more than single circuit) and on the water side, according to the Wieland ONDA standards or different Codes and Procedures. 
Being Shell & Tube exchanger pressure vessels, the safety requirements are assured by strictly following the main European Codes both during the design, the choice and use of suitable materials, the manufacturing and controls, the pressure test and the final documentation.
