Adiabatic Cooling System: SPX Cooling Technologies
SPX Cooling Technologies, Inc. has introduced the Recold Vector™ Adiabatic Cooling System, for halocarbon refrigerant condensing or CO2 gas cooling applications in supermarket refrigeration systems. According to the company, the Recold Vector provides lower energy usage and a smaller footprint than an air-cooled condenser and up to 60% or more reduction in site water usage compared to an evaporative condenser. Designed as a once-through system, the Recold Vector Adiabatic Cooling System minimizes water treatment requirements.
With a condensing capacity of 25-295 tons and a CO2 gas cooling capacity of 32-372 tons, the Recold Vector system aims to enhance the utility of an air-cooled system with the efficiency boost of a wet system during peak conditions. Evaporative pads precool air only on peak days and coils remain dry to maintain efficiency and life expectancy. Electronically commutated (EC) motors help ensure reliable and efficient operation.
The Recold Vector system is equipped with the HydroBLU energy management control system featuring automatic motor programming and either standalone or remote interface control. The control system can be used with setpoint changeover and/or a nighttime limiter. Operational and fault signaling, remote monitoring capabilities, and bypass operations are all provided.
The integral water distribution system provides even water distribution across the cooling pads’ entire surface area, minimizing dry spots. With their fluted angles, the pads direct water flow towards their air inlet side, where most evaporation takes place. A certain amount of water is not evaporated, which helps to continuously rinse the pads. This minimizes inlet scaling and clogging and reduces dirt accumulation on the heat exchanger’s finned surface area.
