TW is a water-condensed chiller that works with R134a refrigerant. It’s a single-circuit unit for indoor installation, with an IP20 protection level. Fitted with the latest two-stage centrifugal oil-free compressor with magnetic suspension to ensure the total elimination of vibrations, an electronic thermostatic valve as standard, and plate heat exchangers (system side and source side) optimised for R134a gas and taking up little space. The machine adjusts the compressor rpm via the inverter (up to 25% of the nominal cooling capacity). It has a device for reducing the starting current, and weighs 5 times less than similar models with twin-screw compressors.
