Tecumseh Products, the United States, has introduced an “eco-friendly” mini chiller using propane (R290) as the primary refrigerant and glycol as the secondary refrigerant. Tecumseh unveiled a prototype of the system at the Chillventa trade show 2016, Germany. The system is slated to undergo field tests. “Two years ago we came to Chillventa with a concept; [this year] we came with a prototype,” said Christian Brac de la Perrière, at Tecumseh.
The outdoor plug-and-play chiller, which contains 12 l of R290, is designed primarily for convenient stores and small supermarkets, but can also be used in restaurants, fast-food outlets, service stations, bakeries, warehouses and other public and private buildings. Its capacity ranges from 6 kW to 36 kW, and it employs Tecumseh’s compressors with a variable-speed drive. “The chiller serves temperatures ranging from 30 °F to 10 °F, and can be used as a condenser for a lower-temperature system,” said Brac de la Perrière.
