Cooling capacity (kW) CGA Air-cooled scroll chillers. Water-cooled chillers range in size from small 20-ton capacity models to several thousand-ton models that cool the world’s largest facilities such as airports, shopping malls and other facilities. EcoPlus Chiller 1/4HP – Recommended capacity: 25-80 gallons; EcoPlus Chiller 1/2HP – Recommended capacity: Up to 132 gallons; As with most refrigeration-type water chillers, EcoPlus’ water chillers require a water pump and tubing, which you have to purchase separately. The condenser on water-cooled chillers is more compact than an equivalently sized air-cooled unit. Water-scarce areas: Use … Chillers, for example, can run at optimum efficiency somewhere between 40 percent and 60 percent of peak capacity. Since the capacity is limited to 150 TR, multiple units cost more than other options. You can derive a chiller's capacity from the temperature drop it creates and the volumetric flow of the water within it. Water-Cooled Chiller = Each ton of chiller requires 1 ton of cooling tower; Mold Temperature Controllers = 1.2 ton per zone + .2 ton/horsepower (heating) Mold Temperature Controllers = use PPH chart + .2 ton/horsepower (cooling) Spot Welders = 1/4 ton per tip (for chilled water) Plating Baths = Heat removal (BTU / hr) = DC amps x DC volts x 2.56 Most other chiller manufacturers cycle the compressor at less than 50% load, which causes increased wear on the compressor and temperature instability. The design cooling capacity Q d is the cooling capacity used to select a suitable cooler. Our Daikin chillers use advanced heat pump and inverter technologies, and optional heat recovery to optimise the unit's performance and manage energy consumption, running costs and reduce carbon emissions. Chiller selection considerations - read our guidance to ensure you get the right cooling equipment for your requirements.
