This device is designed to detect and remove condensate water from air conditioning (AC) units, heat pumps, and refrigeration systems where gravity drainage is not possible.

Technology: Uses reliable, patented piston pump technology that is energy efficient and capable of handling small particles in the condensate. Performance: Offers a maximum flow rate of 20 liters per hour (approx. 5 gph) and a maximum discharge head of 10 meters (approx. 33 ft). Kit Contents: Typically includes the piston pump, a detection unit, tubing with a drain safe device, anti-vibration dampers, a power cable, and various connectors for installation. AT4221
