LightObject's Q1600 Water Chiller offers exceptional performance, consistency, and reliability thanks to the high quality JLD612 PID-controller and our two-stage compressor system. Our unit's feature an oversized capacitor which alleviates issues with circuit over-drawing during starting amperage that are common in other chillers.The JD612 PID controller is capable of achieving a 0.1°C setpoint resolution and features a dual-display that shows both the setpoint and the current system temperature. The compressor utilizes an environmentally-friendly refrigerant, R410A.The internal pump is rated for 10 meters of lift and a flowrate of 12 Liters/min to ensure adequate circulation of water. The unit is suitable for ambient conditions up to 35°C, with a selectable cooling range of 18°C - 30°C.Highlight20% cooling performance improvementIntegrated temperature controller installedBetter temperature control +/- 0.5'C Ideal candidate for a laser machine running a laser tube with a power up to 180W.
