Energy efficient HFO chiller

The new addition to Star’s air cooled Indigochiller range uses the synthetic refrigerant R1234ze, which has a low Global Warming Potential of 6. This is an energy efficient, low noise chiller solution for building services, HVAC and process cooling. 

Star teamed up with Danfoss Turbocor and Honeywell when developing the new range. 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 has a special method of construction designed to minimise the risk of refrigerant leakage and give 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. 

Dr. Robert Lamb, Star’s group sales & marketing director, comments: "This development is part of our long-term customer care strategy. 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. 

We remain invested in the long-term success of our customers and ensure they are prepared so they can be more efficient, productive in what they do, and also meet the energy requirements and regulations, which are becoming more severe as time goes on."
