From freezing and cold chain to cold storage cooling in industrial premises, Alfa Laval has the latest, energy-efficient solutions. For the food industry, we offer highly efficient plate heat exchangers for reliable cooling results and energy savings. Applications range from cooling in abattoirs, fish and meat processing areas, to climate control in storage rooms for fresh food freezing, preparation and sales.
Industrial semi-welded range for higher demand on temperature, pressure and media
Alfa Laval Industrial semi-welded line is used when gaskets are not suitable for one of the process media. Also, the semi-welded line can take a higher design pressure compared to fully gasketed plate-and-frame heat exchangers. This includes cascade duties with natural refrigerants such as R744 and R717.
Tackling the ammonia challenge
U-Turn is a liquid separator especially designed for use with plate heat exchangers in ammonia applications. The module – including the separator and plate heat exchanger ensures minimum pressure drop losses and maximum energy efficiency.
Refrigerants of tomorrow
The refrigeration industry has seen a growing interest in using carbon dioxide (CO2) as secondary media combined with ammonia in cascade applications. Carbon dioxide requires lower pumping cost and smaller pipes then glycol and brines.
However the higher pressure levels of CO2 creates a challenge for the CO2/ Ammonia cascade heat exchanger, mainly related to pressure and thermal fatigue. Alfa Laval has invested significant time and effort in the R&D of semi-welded plate heat exchanger technology for cascade duties.
