WATER-COOLED/CONDENSERLESS LIQUID CHILLERS 30WG/30WGA 020-090 Features and advantages ■■ ■■ ■■ ■■ ■■ ■■ COOLING Reduced footprint Scroll compressors and R-410A refrigerant Variable-flow pump Low-noise option (-3 dB(A)) Stacking of two units for increased capacity Several communication protocols available: JBus, BacNet, MS/TP, LON ■■ Water connection at the top or rear (30WG only) Water connections at the rear of the unit Available versions 30WG - optimised for air ­conditioning and process cooling ■■ Evaporator temperature down to -12 °C ■■ Condenser temperature up to +60 °C ■■ Condensing pressure control devices available Water connections at the top of the unit 30WGA - optimised for air conditioning ■■ Continuous operation up to 62 °C saturated condensing temperature ■■ Compatible remote condensers available ■■ Optimised remote condenser fan control The right unit for any application ■■ In 30WG units the pressure control signal ensures safe unit operation and maximised performance at low ­ source-side water temperatures. ■■ The condenserless 30WGA units are 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 ■■ The 30WG units can be provided with several hydronic kit options, both on the evaporator and/or condenser side, with different levels of available pressure and variable or fixed-speed pumps (see page 7). ■■ Remote condenser fan control possible for 30WGA units. 216 C A R R I E R 2 0 1 6 / 2 0 1 7
