The CoolCoil Nutrient Cooler is a stainless steel coil that 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.
