Sustainable refrigeration solutions
Today, there are huge opportunities to reduce the carbon footprint of industrial and commercial refrigeration systems. New, more efficient refrigeration technology makes it possible to reduce energy consumption and, as a result, emissions. At the same time, greenhouse gases emitted from traditional refrigerants can now be eliminated by switching to natural alternatives like ammonia or, paradoxically, CO2 itself.
With knowledge gained from 90 years of experience with plate heat exchanger technology, Alfa Laval has developed a broad portfolio of heat exchanger solutions that are enabling new sustainable possibilities in both commercial and industrial refrigeration systems. Contact us today to learn how our sustainable refrigeration solutions increase efficiency by up to 10%, resulting in around 5500 GWh of annual energy savings. We can also support you with unique solutions for resolving the challenges of switching to natural refrigerants.

Commercial refrigeration
Alfa Laval’s wide range of heat exchangers is found in numerous residential and commercial climate applications – including air conditioning (chillers), tap-water heating (boiler/solar), heat pumps and transport refrigeration.
Industrial refrigeration
From industrial freezing and cooling to refrigeration of ice rinks and food processes, Alfa Laval offers the latest, energy-efficient plate heat exchanger solutions. For the food industry, we offer highly efficient air coolers that can be combined with plate heat exchangers.
Applications range from cooling in slaughter houses and fish and meat processing areas, to climate control in storage rooms for fresh food.
Marine refrigeration
Refrigerants are common in the marine industry, from chilling and freezing the catch on fishing vessels to air conditioning on cruise ships. Yet the refrigerant types are changing rapidly, giving way to hydrofluorocarbon (HFC) refrigerants and natural refrigerants like CO₂. Alfa Laval has the heat exchanger solutions and expertise to support natural refrigerant choices onboard food transportation ships and cargo vessels, cruisers and ferries, gas/LPG carriers and more.
Natural refrigerants
Around the world, there is a move away from traditional refrigerants in favor of refrigerants with lower global warming potential (GWP) and a rapidly increasing market for natural refrigerants such as ammonia, CO2 and hydrocarbons.
Alfa Laval is home to some of the market’s leading experts on the subject of natural refrigerants. Their expertise has allowed us to develop a wide range of heat exchanger solutions specially designed to handle the unique demands of working with challenging and sometimes dangerous substances like carbon dioxide, ammonia and propane.
Our solutions
AlfaNova fusion-bonded plate heat exchangers
Built with our unique fusion bonding method, AlfaNova's 100% stainless steel design can withstand more extreme temperatures and pressures with greater fatigue resistance. It therefore offers a highly compact and efficient solution for cooling of very clean, sensitive liquids and when taking advantage of the low-GWP potential of ammonia.
Industrial semi-welded plate heat exchangers
Our compact semi-welded heat exchangers enable even higher efficiency and reliability when using ammonia as a low-GWP refrigerant in industrial refrigeration applications. Alfa Laval semi-welded heat exchangers are also ideal in cascade systems operating with CO2 as a secondary medium for freezing applications, reducing ammonia charge while preventing the risk of cross-contamination with their proven RefTight™ sealing system.
AC brazed plate heat exchangers
The AC line of brazed plate heat exchangers offers top thermal performance in evaporation and condensing duties, while maintaining a compact footprint. Alfa Laval has specially engineered the AC line for refrigeration/air conditioning chiller applications and heat pump applications and will optimize your distribution system based on choice of refrigerant.
CB brazed plate heat exchangers
Our CB range of brazed plate heat exchangers feature high efficiency, superior mechanical resistance and a compact footprint, making it ideal for demanding installations where space is at a premium. That’s why the Alfa Laval CB range has become a common replacement for other types of heat exchangers in refrigeration and many other applications.
White paper: Navigating a changing refrigerants market
A massive change is currently underway in the refrigerants market. Driven by environmental concerns, legislation is pushing a gradual phase out of traditional refrigerants in favour of new alternatives with lower global warming potential (GWP). Download this white paper for a fundamental primer on selecting and accommodating alternative refrigerants for diverse heating and cooling applications.
See the potential: Refrigeration energy efficiency
Did you know that millions of Alfa Laval heat exchangers are installed in refrigeration applications all over the world? Combined, they help our customers save over 5.5 TWh of electrical power every year! That translates to an over 1-million-tonne reduction in CO2 emissions.
In fact, if efficient Alfa Laval solutions were used in all new installations, we could reduce emissions by a further 144,000 tonnes. That’s like getting rid of 470 flights between London and Singapore!
