Refrigeration and cooling

Keeping cool

Refrigeration and air-conditioning consume a lot of energy. Therefore, it is essential that the technical solutions minimize energy usage.

Refrigeration duties require high heat transfer efficiency, a small footprint, reduced refrigerant charge through low hold-up volume, and use more environmentally friendly refrigerants. Alfa Laval supplies different heat transfer solutions that meet all these demands:

• semi-welded plate heat exchangers
• fusion-bonded plate heat exchangers
• brazed plate heat exchangers
• shell-and-tube heat exchangers
• all-welded plate heat exchangers
• air heat exchangers (not available in the USA)

Alfa Laval’s refrigeration applications include:

• Air-conditioning, where our evaporators and condensers play a vital role.
• Commercial refrigeration, in supermarkets and small and medium food stores. Our focus is on developing systems based on natural refrigerants like carbon dioxide, ammonia and hydrocarbons that can replace freon.
• Industrial cooling and refrigeration, air-conditioning of offices and industrial premises and refrigeration of ice rinks. We offer solutions that can cope with aggressive fluids, high pressures, and very low temperatures. 
• Industrial process refrigeration, in the food, beverage, pharmaceutical and chemical industries. We supply indirect systems that keep the total refrigerant volume low, ensure easy control of possible leakage, and facilitate energy recovery.
• Marine refrigeration and air conditioning. Our systems are used onboard fishing vessels, gas carriers/LPG, cruisers/ferries, food transportation ships, and cargo vessels.
