Poultry processor cuts costs with efficient waste heat recovery
With the new system, heat taken from their 14°F refrigeration load is lifted to 126°F in one stage for heating. The ammonia heat pump solution has reduced heat energy cost by 72% and saves fifteen million gallons of water per year.

World-class ice rink chooses Vilter® single screw compressors
Three Vilter VSS-1201 Ammonia single screw compressor units were installed to provide the refrigeration capacity. Each unit is rated at 268 tons when operating at -4.3° F suction temperature. Each compressor is powered by a 450 HP high efficiency motor with 96.2% nominal efficiency.

Pharmaceutical company eliminates HFCs with low-charge ammonia approach
Emerson built a refrigeration package that uses a low refrigerant charge that improves safety and reduces certification costs. The whole system was factory built and ready to operate when delivered to the site.

Nestlé cutting costs with efficient waste heat recovery
With the new system, heat can be taken from the 32oF process glycol and lifted to 140oF in one stage for heating. Since commissioning in May 2010, Nestlé Halifax is heating around 14,000 gallons of water each day to 140oF.

Emerson Heat Pump Technology Heats a City Using Frigid North Sea Water With Zero Global Warming Impact
By using ammonia, Emerson’s compressor technology solution offered Star Refrigeration and its project partners in Norway – Norsk Kulde and Drammen Fjernevarme – a refrigerant that has a good environmental profile, delivers higher temperatures and provides superior performance benefits from its consumed resources than competing technologies.
