High efficiency units RHD with eco-friendly refrigerant gas R134a are intended to fully satisfy any cooling application requirement. The perfect union between semi-hermetic screw compressors and unique design, allows these units to operate in critical climate conditions. In fact, RHD units stand out as some of the most solid and reliable of the market. RHD series has been developed to reduce installation work to a minimum, offering a range of plug & play units. This is also possible thanks to the availability of a complete selection of version/configurations/accessories.
Models up to 2300 kw (650 TON) with:
air cooled condenser with semi-hermetic screw compressors, Axial fans and large surface condensing coils water cooled condenser with semi-hermetic screw compressors and shell & tube heat exchanger
Each unit can be matched with external pumping groups specified according to every possible plant requirement. Other available versions:
- High energy efficiency
- Integrated free cooling
- Heat pump
- Noise reduction system
- Partial or total heat recovery system
- Unit remote control display
- RS485 serial port for the following protocols: MODBUS/ECHELON/BACNET/BACNET OVER-IP
…. And with the free cooling additional energy saving!
The highest efficiency is obtained by equipping RHD units with INTEGRATED FREE COOLING. This feature utilizes the ambient air, when it is colder than the returning process fluid, to allow operation of the chiller without the compressors with energy savings up to 90%.
