An ammonia heat pump from German manufacturer GEA is being used in a project using the water in an abandoned coal mine to supply a 6MW district heating network.

Mayekawa, a leading Japanese manufacturer of natural refrigerant refrigeration equipment, exhibited the new fourth-generation model of its NewTon ammonia (R717)/CO₂ (R744) industrial refrigeration unit.

Cimco Refrigeration, a Toronto-based industrial refrigeration contractor, has reduced energy consumption at a Quebec-based meat-processing plant operated by Viandes Paquette by 2.5 million kWh annually with a low-charge ammonia/NH₃ (R717) system. By reclaiming excess heat from the ammonia system, Cimco removed the need for any boilers at the plant.

German manufacturer Gea Heating & Refrigeration Technologies is expanding its ammonia product portfolio, adding two screw CompaX compressors and a brand-new Grasso X semi-hermetic screw compressor package.
