Tapping into market demand for low-charge ammonia HVAC&R systems, German multinational GEA will present its new RedGenium series of low-charge ammonia (NH3) heat pumps at Chillventa next week.

“The future of industrial heat supply belongs to environmentally friendly heat pumps,” said GEA, from sources such as unused waste heat or unrestrictedly available heat from surface waters.

The RedGenium is designed to minimise the required refrigerant charge, and purports to offer “lasting sustainability through durability, compact design and selected components,” said the company ahead of Chillventa.

Designed specifically for the smaller output range at heat transfer temperatures up to 70°C, the three RedGenium heat pump models are equipped with efficiently designed heat exchangers and a 39-bar compressor for applications in most industrial processes.

The RedGenium is a turnkey solution with a heating capacity of approximately 500-1,100 kW. GEA argues that its compact design makes the heat pump easy to install and maintain. Short, 3D-shaped pipe connections with a minimum number of welds help to increase safety.

The Chillventa tradeshow, the next edition of which takes place in the German city of Nuremberg from 16-18 October 2018, is the world’s biggest gathering of HVAC&R technology manufacturers and enthusiasts.

Harnessing the Grasso V-HP compressor

At the show, the company will also showcase the Grasso V-HP (a high-pressure reciprocating compressor model for NH3 heat pumps), and the BluQ, a low-charge NH3 chiller for air-conditioning large buildings, which was launched at Mostra Convegno Expocomfort earlier this year (March 2018).

The Grasso V-HP compressor is at the RedGenium’s heart. Designed as simply as possible, without the need for an oil separator and without special cylinder head cooling, the compressor’s dynamically stressed components are adapted to the requirements of a heat pump.

“Heat pump-based systems combine performance and energy efficiency with sustainability and low costs,” GEA argued.

The firm will also present its CO2 transcritical and propane-based compressors in Nuremberg.
