120-volt Sunleaves AquaChill units have push-button temperature regulation, cleanable air filters, specializedsockets for external heater connection and a one-year warranty against defects. AquaChill 132 units have durable ABS housing and water outlets that rotate 360 degrees to accommodate either .5- or .75-inch tubing. Gardeners simply connect a high-performance pump and their nutrient solution temperature is reduced as it circulates through the unit’s internal titanium thermal converter.
