High temperature heat pump HT25W +95 °C

High temperature heat pump HT25W 95°C

– high temperature water-water up to +95 °C with R515B

High temperature heat pump HT25W +95°C high temperature with refrigerant R515B is an innovative and ecological solution for providing heating and domestic hot water with temperatures up to +95 °CDesigned for industrial, commercial and special applications, it offers high performance, reliability and energy efficiency.

Areas of application

• centralized heating systems (CTP, thermal power plants);
• industrial processes (pasteurization, washing, technological processes);
• medical institutions and laboratories (sterilization, technological water);
• hotels and SPA centers (DHW, swimming pool heating);
• existing systems with radiators (high temperature circuits);
• modernization of old gas/diesel boilers without replacing radiators.

High temperature heat pump HT25W +95 °C for industrial applications

High temperature heat pump HT25W +95°C high temperature is designed for commercial and industrial applications which require hot water at high temperatures. It is ideal for integration into existing or new systems requiring high flow temperatures. up to +95 °C, with a stable heat source from well water, river or geothermal system.

Why is R515B the ideal choice?

R515B is a non-flammable refrigerant (class A1), based on R-1234ze and R-227ea, ideal for buildings with high safety requirements (medical, school, public institutions). It allows temperatures up to +95 °C without fire risks.

• compatibility with R134a compressors;
• excellent thermal stability, no toxic decomposition products;
• Low GWP — only 292 (according to F-Gas);
• high efficiency with EVI technology;
• operational safety — class A1 (non-flammable).

EVI technology — vapor injection

The system EVI (Enhanced Vapor Injection) increases the performance of the heat pump at high temperatures. By intermediate injection of superheated vapor into the compressor, the following is obtained:

• flow temperatures up to +95 °C without overload;
• COP increase by up to 25–30% compared to classic systems;
• improved heat exchange, reduced risk of cavitation;
• stable operation at variable loads and temperatures.

High temperature heat pump HT25W. Advantages of the water-to-water system

• high stability of the source (soil, well, lake, river);
• Higher COP than air-to-water systems;
• effective use throughout the year;
• without freezing the source, as happens with air-water.
