EcoPlus 1/2 HP Water Chiller | 132 Gallon R134a Titanium

The Temperature Window the EcoPlus 1/2 HP Chiller Actually Covers This is the half horsepower EcoPlus chiller, with the widest set point range of the three. It holds water anywhere from 37 to 90 degrees on a maximum volume of 132 gallons. That makes it as useful for a cold propagation tank as for a warm reservoir. Refrigeration is a freon-free R134a circuit over a pure titanium evaporator. It draws 4.4 A at 120V, plumbs with 3/4 in male NPT and hose fittings, and asks for a circulation pump between 317 and 793 GPH. The cabinet measures 21 x 15.5 x 22 in and weighs 52 lbs. Over current protection and memory hold the set point through a power cut. Running a 132 Gallon Reservoir Chiller With Two Pumps A 132 gallon reservoir chiller at this capacity needs two pumps rather than one, and that catches people out. One moves water through the chiller loop and the other feeds the system. Making a single pump do both starves whichever job it is not doing. The chiller pump should sit low in the tank where the coldest water collects, inside a filter bag. Japanese compressor, digital control, and a sensor reading the return rather than the tank. The display and a handheld thermometer will disagree by a degree or two. That gap is normal and worth learning rather than chasing. This unit is a floor-standing appliance at this weight, and it wants clear air around the exhaust face. Key Features 37 to 90 degree range: Wide enough for cold propagation work as well as normal reservoir holding. 132 gallon maximum: Covers a large single tank or a linked bank of DWC vessels. R134a refrigeration: Freon free circuit with the efficiency to hold a set point rather than cycle hard. Pure titanium evaporator: Anti corrosive, so nutrient solution and salt water are both within spec. 3/4 in male NPT with hose fittings: Plumbs to rigid or flexible without an adapter hunt. Over current and memory protection: Comes back to the same set point after a power interruption.
