The CoolCoil Nutrient Cooler is at stainless steel coil with 1/2" FPT fitting which allows you to use one chiller to cool multiple reservoirs. It also keeps you from having to circulate nutrient water directly through your chiller system, expanding your options on the type of chiller you can use and prolonging its life. (Nutrient water generally has a high salt content, which is really hard on the internal components of any chiller). Simply submerge the CoolCoil in your nutrient reservoir and circulate cold water through it. Use in conjunction with the WaterGate and Resistat when cooling reservoirs in separate rooms to ensure consistent temperatures throughout.
Available in lengths of 12.5, 25, or 50 foot lengths. The CoolCoil Nutrient Cooler is modular, allowing multiple units to work in conjunction to meet your cooling needs. Typically, 1 foot of coil is needed per 12.5 gallons of reservoir space, meaning a 10 foot coil will effectively cool a 125 gallon reservoir.
