British hospital reduces carbon footprint by switching to ammonia.

Reduced Environmental Impact

Since switching to a new ammonia-based cooling system based around Alfa Laval heat exchangers, the Homerton University Hospital has increased cooling capacity by 50 percent. They have also significantly reduced the refrigerant charge, and achieved a reduced environmental impact.

At first the hospital was wary of using natural refrigerants in their cooling system, but a combination of superior efficacy, reduced greenhouse gases and enhanced safety features convinced them to adopt a new system run on ammonia.

With the transition, more than 300 kg of R22 has been replaced with just over 50 kg of ammonia. Yet despite the huge reduction in refrigerant, the hospital has achieved a 50 percent increase in cooling capacity.

APS are the Official UK Partner for Alfa Laval who are a major manufacturer in the industrial refrigeration sector and operate in various segments of the market.
