I have eleven brand new, never been used 20' CoolCoils that retail new for $139+ and three 10' CoolCoils. Each unit includes...
12" coil of 3/8" stainless steel tubing that was 20' long prior to being coiled
(6) Stainless steel hose clamps
(2) 10' sections of 3/8" ID high quality tubing (10' red & 10' blue)
(2) 3/8" hose barb to 1/2" NPT thread adapters
(2) 3/8" to 1/2" hose barb adapter
The CoolCOIL is a drop-in nutrient reservoir cooler capable of cooling up to 100 gallons. This stainless steel coil will not corrode in nutrient solution and will last a lifetime! If you have a larger reservoir, simply add a second or third coil for greater surface area and additional cooling capacity. Use with a thermostat (hydrostat) and gateway valve to control temperature.
