EC-1 Series

EC-1 Series

The EC-1 Series of mini-split pumps are automatic condensate removal systems designed to remove the water from a ductless mini-split air conditioner evaporative coil when gravity-feed drainage is not possible or practical. Series models include improved noise reduction, reliable solid-state switching technology, and easy to install mounting brackets to create a pump that benefits contractors, installers, and end-users.
The EC-1K Series applications include wall-mounted, ceiling and fan coil-split air conditioning equipment.

  • EC-1

    The EC-1 model is designed to accommodate multiple electrical requirements within one pump.
    The EC-1 Series is a new concept for mini pumps incorporating an improved noise reducing design and reliable solid-state switching technology. Easy to install brackets provide a quick and precise method to accurately position and secure both parts of the pump quickly. The two-piece design allows the reservoir to be placed within the air handler while the pump-controller is located outside the air handler. The two components are connected via a convenient communications wire and suction tubing.
    EC-1 is designed for use in removing condensate from wall mount, ductless mini-split air conditioners up to 34,000 Btu. It can also be used to remove condensate from fan coils and suspended ceiling air conditioners. The pump can be installed above the air conditioner in a false ceiling, behind the wall mount air handler, or in plastic conduit or line-set channel. The reservoir, featuring a clear tank, connects to the condensate drain hose and must be positioned flat and horizontal while the pump can be oriented in any position within 1 m.
