Thermocold QUATTRO EA Four-pipe R454B 86-345kW
Low Temperature Four-Pipe R454B

The Quattro EA R454B is a state-of-the-art air-to-water, four-pipe heat pump for medium and large buildings needing year-round comfort. It provides simultaneous heating and cooling with two independent water circuits—perfect for offices, hotels, public buildings, education, and healthcare. Using eco-friendly R454B refrigerant, it delivers high efficiency (TER up to 8.2, COP up to 3.55) and hot water to 60°C, with operation down to -15°C. Heating capacity ranges from 86 to 345 kW, cooling 81 to 321 kW. The compact unit fits easily into plant rooms and is installer-friendly.

Features:

  • Scroll compressors (IDV) for top efficiency
  • Dual refrigerant circuits for true simultaneous operation
  • EC fans (EA models) for low energy and quietness
  • Stainless steel brazed-plate exchangers, frost protected
  • Thermologic advanced controller with 7" touch display, BMS-ready (BACnet, Modbus, LonTalk)
