The Irish heating specialist has launched a high-temperature heat pump that delivers hot water up to 110 C and heating capacities from 100 kW to 370 kW for industrial and district heating applications. The system achieves a temperature coefficient of up to 4.63.
Ireland-based heating technology manufacturer Trane has launched a new range of high-temperature water-to-water heat pumps for industrial and commercial applications.
The City RTSF HT heat pump operates in heating mode with source-side temperatures ranging from 30 C to 62 C and can deliver heat sink temperatures up to 110 C, making it suitable for retrofit projects, process heating and applications where hot water production is above standard heat pump limits, the company said.
The unit is available in three sizes – 066, 076 and 086 – with heating capacities ranging from 100 kW to 370 kW. At nominal conditions, the largest model can provide up to 370 kW of heating power. “Built on Trane’s proven XStream platform, the RTSF HT delivers hot water temperatures up to 105 C and heating capacities up to 1,500 kW,” the company said.
The system uses a screw compressor and the hydrofluorolefin (HFO) refrigerant R1233zd, which is often used in high-temperature chillers and heat pumps.
Trane said the unit achieves a coefficient of performance (COP) of 4.30 to 4.63 at evaporator water temperatures between 45 C and 50 C, and 3.17 to 3.33 at evaporator water temperatures between 40 C and 45 C. The heat pump is equipped with adaptive frequency drive technology for variable speed operation, allowing output to be adjusted to heating demand and improving part-load efficiency.
The RTSF HT has a footprint width of 930mm, which the company says makes it suitable for installations with limited space.
According to Trane, the heat pump is designed for water-to-water heating applications up to 110 C, including industrial processes such as food and beverage production, pharmaceutical production and biogas plants, as well as district heating and cooling networks. It can also be used for heat recovery from chillers or refrigeration systems and as a second stage heat pump in cascade heating systems with air or water source.
“Trane’s RTSF HT is distinguished by its use of standardized, fully validated and proven Trane technology, including proprietary screw compressors and Symbio 800 controls,” the company said. “The units are manufactured at Trane’s European facility with state-of-the-art testing capabilities and are supported by the company’s sales and service network in Europe, the Middle East, Africa, Australia and New Zealand.”
