The 30WG/30WGA units are new Carrier chillers and 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.

  • 30WG optimized for cooling/low temperature heating (For high temperature heating, refer to 61WG range)
  • Compact design
  • Plug and play approach
  • High efficiency

30WG - optimized for air conditioning and process Heating & Cooling
  • Evaporator temperature down to -12 °C
  • Condenser temperature up to +60 °C
  • Condensing pressure control devices available
  • Heat recovery possible with external PGHE
30WGA - optimized for air conditioning
  • Continuous operation up to 62 °C saturated condensing temperature
  • Compatible remote condensers available
  • Optimized remote condenser fan control

General description

  • Reduced footprint
  • Scroll compressors and R-410A refrigerant
  • Variable-flow pump
  • Low-noise option (-3 dB(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 (30WG)

The right unit for any application

  • Option 153 “Built-in DHW and space heating control” allows control of both domestic hot water and space heating requirements:
    • Domestic hot water production
    • Space heating control
    • Control of auxiliary systems
    • Pump control
  • In 30WG units the pressure controls signal ensures safe unit operation and maximized performance at low source-side water temperatures
  • Ideal for refurbishment projects where a remote condenser exists on site, and for all projects without geothermal/natural sinks for heat rejection

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
  • If option 153 is selected domestic hot water production is controlled via a built-in three-way diverter valve (not supplied)
  • Remote condenser fan control possible for 30WGA units

Compact high-performance product range

  • Small footprint, ideal for refurbished buildings, allows access in very tight plant rooms
  • 30WG: High SEER and SEPR. Units optimized for process and comfort applications
  • Variable-flow pumps reduce system energy consumption
  • The entire range offers low sound levels, allowing installation in any building type. The low-noise option ensures enhanced acoustic comfort (-3 dB(A))
  • Equipped with the latest generation R-410A scroll compressor, optimized for typical operating conditions for water-sourced units

Touch Pilot Junior control
