Alfa Laval is a leading innovator in the field of compact plate heat exchangers for refrigeration and heat pump systems. Most of our units are installed in cold storage rooms, ice rinks, marine applications, HVAC, district energy, process cooling, and food and beverage. We work closely with leading local installers and system builders from across the globe, supplying both standard and customized solutions. We focus largely, but not exclusively, on applications that employ natural refrigerants.
The keys to sustainable industrial refrigeration
- Use natural refrigerants such as ammonia, carbon dioxide, and hydrocarbons, in optimized solutions.
- Boost efficiency with Alfa Laval heat exchangers, whose minimal pressure drop and close temperature approach shorten the system’s payback time.
- Choose Reliable plate heat exchangers from Alfa Laval. Many of the nearly 100,000 units we’ve supplied have been in use for decades.

Shecco has more than 15 years of expertise in offering innovative, effective, flexible solutions to speed market entry. Alfa Laval has been a partner from the start.
IIAR is a technical member organization with industry representation from all facets of the natural refrigeration community, including manufacturers, engineers, contractors, end-users, academics, scientists, trainers, and more. IIAR is a leading advocate for the safe, reliable and efficient use of ammonia and other natural refrigerants.
U-Turn is a liquid separator especially designed for use with plate heat exchangers in ammonia applications. The compact module, including the separator and plate heat exchanger, reduces pressure loss, while also ensuring a low ammonia charge and maximum energy efficiency.
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.
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.
Advanced solutions for industrial refrigeration
Semi-welded plate heat exchangers
Our compact semi-welded heat exchangers enable even greater efficiency and reliability in industrial refrigeration applications that use ammonia as a low-GWP refrigerant. Alfa Laval semi-welded heat exchangers are also the right choice for cascade systems that operate with CO2 as a secondary medium for freezing applications. These exchangers reduce the ammonia charge and also prevent the risk of cross-contamination with their proven RefTight™ sealing system.
Most plate heat exchangers used in commercial or small capacity industrial refrigeration are brazed with copper. While suitable for many applications, copper reacts negatively with ammonia, an important natural refrigerant. Built with our unique fusion-bonding method, AlfaNova offers the market’s only 100% stainless steel plate heat exchanger. It is a compact, efficient solution for cooling very clean, sensitive, liquids, which takes advantage of ammonia’s low-GWP potential.
Brazed plate heat exchangers
Our copper-brazed plate heat exchangers are a compact, efficient, and maintenance-free solution for heating, cooling, evaporating, and condensing in a wide range of refrigeration applications. They work with most types of environmentally friendly, low-GWP refrigerants, including important natural refrigerants, such as CO2 and hydrocarbons. Each unit is designed with a range of unique features that ensure superior thermal performance and reliability.
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.
