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.
