Turn to efficiency

When used as flooded ammonia evaporators, Alfa Laval semi-welded plate heat exchangers can offer a temperature approach as low as 2 degrees Fahrenheit and are extremely thermally efficient with compact dimensions.  To go along with our top of the line heat exchanger line, we have developed our patented U-Turn separator with an integrated drop leg, oil pot, and nozzle connections to provide a modular compact solution to be used in for flooded ammonia applications for industrial refrigeration.

 

The U-Turn has smaller overall dimensions than a traditional separator while offering efficient separation through the use of four different separation methods with a low ammonia charge.  This modular vessel is designed to attach directly to the carrying bar of the heat exchanger with no external support required and is available in a variety of configurations for a range of our heat exchanger models.

RefTightTM sealing system

High performance gasket sealing, for high-pressure duties. The RefTight™ sealing system enables enhanced, long-term performance in applications with high pressures and temperatures. The weld is positioned outside the separate ring-gasket groove, which ensures reliable sealing, extends the lifetime of the gasket, and prolongs service intervals.

Integrated subcooling

Most refrigeration systems consume vast amounts of electricity; energy efficient design can result in substantial economic savings. Integrating subcooling into the condenser of the plate heat exchanger makes it possible to improve the energy efficiency of compact heat exchangers, without the need for extra pipe work or additional components.

Discover why Semi-welded plate heat exchangers are a good fit for high pressure refrigeration systems

Concerns over climate change have driven the refrigeration industry to place more focus on natural refrigerants. CO2 is a natural refrigerant growing in popularity in our refrigeration systems, but it comes with the challenge of designing components rated for higher pressures. Join us to learn more about Alfa Laval’s Industrial Refrigeration heat exchangers for high pressure applications.

Semi-welded GPHE: Benefits for industrial refrigeration

Alfa Laval semi-welded plate heat exchangers combine the flexibility and serviceability of normal gasketed plate heat exchangers with higher pressure resistance, making them ideal for industrial refrigeration applications. They are highly resistant to the formation of ice, as well as to fatigue stress caused by extreme pressure and temperature variations, and are suitable for use with most types of primary refrigerants and secondary fluids, including ammonia and carbon dioxide.
