61WG (29-230kW) Water-to-Water Heat Pumps | Carrier UK

The 61WG units are new Carrier heat pumps designed for commercial (offices, small hotels, leisure facilities), residential and industrial applications. All units offer a unique combination of high performance and functionality in an exceptionally compact chassis.

  • 61WG optimized for heating
  • Compact design
  • Plug and play approach
  • High efficiency

General description

  • Reduced footprint
  • Scroll compressors and R-410A refrigerant
  • Variable-flow pump
  • Low-noise option (-3dB (A))
  • Stacking of two units for increased capacity (up to size 090)
  • Several communication protocols available: JBus, BacNet, MS/TP, LON
  • Water connection at the top or rear

Optimized for Heating

  • High temperature up to +65 °C
  • Evaporator temperature down to -5 °C
  • Control of the three-way diverter valve for domestic hot water and space heating requirements
  • System approach – the Heating System Manager maximizes the global efficiency of complex systems where the 61WG units are combined with an auxiliary heating source to serve multi-zone space heating and domestic hot water production
  • Compatible with most heating systems, both in new and refurbished buildings and permits domestic hot water production (with a dedicated temperature setpoint)

Adaptability and simple installation

  • Can be provided with several hydraulic module options, both on the evaporator and/or condenser side, with different levels of available pressure and variable or fixed-speed pumps
  • Water side heating reversibility

Compact high-performance product range

  • Small footprint, ideal for refurbished buildings, allows access in very tight plant rooms
  • High SCOP satisfies even the most stringent standards, with a leaving water temperature of up to 65 °C without supplementary system
  • Variable-flow pumps reduce system energy consumption
  • Offers low sound levels, allowing installation in any building type
  • Equipped with the latest generation R410A scroll compressor, optimized for typical operating conditions for water-sourced units
