indigoUK: Star Refrigeration has added an HFO chiller to its high efficiency Indigochiller range. 

The new addition uses the synthetic low GWP HFO refrigerant R1234ze as an alternative to R134a.

Star teamed up with Danfoss Turbocor and Honeywell when developing the new range of Indigochiller at their design and manufacturing facilities in Glasgow.

A year of factory and field testing followed to verify performance, and analysis of the data collected has confirmed that the HFO Indigochiller delivers increased efficiency and lower total cost of ownership (TCO).

The Indigochiller range is said to have a special method of construction designed to minimize the risk of refrigerant leakage and increase an efficient operating life of 20+ years.

The system includes welded steel pipes, bellows, seal valves and epoxy-coated condenser fins as standard, ensuring high build quality and leak tightness.

“This development is part of our long-term customer care strategy,” said Rob Lamb, Star’s group sales and marketing director. “It allows us to give our customers confidence that we can help them transition to low GWP refrigerants moving forward, and at the same time, reduce operating costs.”
