Chillers and Heat Pumps | Water-Cooled Chillers and Heat Pumps

YVWA Water-cooled VSD screw compressor chiller

Cooling capacity from 545 kW to 1067 kW Heating capacity from 600 kW to 1000 kW
R513A
Features
Key components The YVWA reduces operating expenses with the application of a standard variable speed drive Inverter ( VSD ).
Application flexibility Tailor and tune flexilibilty makes the YVWA ideal for any high lift application , primarily Heat Pump duty higher than 50 ° C hot water set point , glycol and low temperature process cooling .
Enhanced sustainability Achieved through high efficiency operation and low refrigerant charges .
Options / Accessories
• BMS Interfacing options
• Heat pump up to 60 ° C hot water production
• Different options of tubes and nozzle arrangements for the heat exchangers
• Dual pressure relief valve
• Several options for flow switches
• Thermal insulation options
• Anti-vibration mounts options
Product confidence R-513A is a refrigerant that is classified as A1 . It combines zero ODP and lower GWP ( 631 , F-Gas ) than R-134a . It offers higher specific cooling capacity ( kW / kg ref .) compared to R-1234ze and therefore it is ideal for small footprint retrofit applications .
