First revealed by the Cooling Post back in June, Trane’s introduction of the Series E CenTraVac marked the first introduction of a chiller using the new HFO and was the result of cooperation with Honeywell.
Trane and Honeywell introduced the new refrigerant, marketed by Honeywell as Solstice zd, to visitors to Chillventa today.
“The Series E is consistent with our company-wide commitment to introduce products that are significantly more energy and operationally efficient, and reduce greenhouse gas emissions,” said Dave Regnery, president of Trane North America, Europe, Middle East, and Africa.
“The Series E CenTraVac is 10% more energy efficient than the next available chiller and it uses refrigerant with significantly lower GWP. We want to offer our customers chiller options that fit into the environmental plans of our customers without compromising safety, reliability and performance.”
The Trane Series E CenTraVac is a large-capacity chiller (capacities from 2600kW to 14,000kW) for applications like comfort cooling of large commercial buildings including district cooling. It is available in Europe, the Middle East and other 50Hz markets, and received Air–Conditioning, Heating and Refrigeration Institute (AHRI) Certification.
Solstice zd is a REACH-registered and US SNAP-approved alternative to R123 and 245fa. It has a GWP of 1. It will have applications in large centrifugal chillers, organic Rankine cycles and high temperature heat pumps.
“Honeywell is committed to developing environmentally-preferable refrigerants that are highly effective and easy for customers like Trane to adopt,” said George Koutsaftes, global business director for the Honeywell refrigerants business. “The use of Solstice zd in the Trane Series E chiller is great news for the environment and building owners who want to transition to a refrigerant with a lower global warming potential and fantastic energy efficiency performance.”
The Trane Series E CenTraVac builds upon direct-drive, multi-stage, semi-hermetic low pressure design technology and allows for heat pump, heat recovery and free-cooling applications resulting in increased sustainability. It also offers an “ice making” feature for ice-enhanced cooling during peak demand.
