The liquid Chillers of the CHA/Y/FC 1202-B÷6002-B series, with R134a refrigerant, offer innovative technology to meet the needs of large systems for both domestic as well as industrial applications requiring the production of cooled water continuously year-round.
During the cold months, in FREE-COOLING operating mode, the liquid returning from the system is cooled directly by forced convection of outdoor air through the condensing coil, thus saving energy by not operating the unit's Screw compressors. A 3-Way valve system is controlled by the electronic microprocessor controller, allowing functioning in CHILLER, FREE-COOLING or MIXED (simultaneously CHILLER and FREE-COOLING) modes.
Are available as option the new EC Inverter fans with high available static pressure and efficiency.
The models 1202-B÷11702-B are compliant to ErP 2021 Regulations for process cooling application with EC or ECH accessory (EC Inverter fans). The models 1902-B÷6002-B are compliant to ErP 2021 Regulations for process cooling application if provided with EC or ECH accessory (EC Inverter fans) and ID accessory (Inverter on all compressors).
On request, units can be supplied with R513A refrigerant.
