  • Harwil CF-112 Chemical Feed Pump Controller

    Manufacturer Series
    Harwil CF-112

    Harwil® type CF-112 chemical feed pump controllers are stand alone interface modules that automatically actuate a chemical feed pump when primary bulk fluid begins to flow. These modules can be used in isolated stand alone systems or as part of large complex systems. Typical uses are for metering and/or adding chemicals in both continuous and batch fluid systems such as: well water, drinking water, waste fluid processing, cooling tower pH/orp control, metal plating make up solutions, and boiler treatment additives.

  • Harwil CF-12/1G Chemical Feed Pump Controller

    Manufacturer Series
    Harwil CF-12/1G

    Harwil® type CF-12/1G one gang chemical feed pump controllers are stand alone interface modules that automatically actuate a chemical feed pump when primary bulk fluid begins to flow. These modules can be used in isolated stand alone systems or as part of large complex systems. Typical uses are for metering and/or adding chemicals in both continuous and batch fluid systems such as: well water, drinking water, waste fluid processing, cooling tower pH/orp control, metal plating make up solutions, and boiler treatment additives.

  • Harwil CF-12/2G Chemical Feed Pump Controller

    Manufacturer Series
    Harwil CF-12/2G

    Harwil® type CF-12/2G two gang chemical feed pump controllers are stand alone interface modules that automatically actuate a chemical feed pump when primary bulk fluid begins to flow. These modules can be used in isolated stand alone systems or as part of large complex systems. Typical uses are for metering and/or adding chemicals in both continuous and batch fluid systems such as: well water, drinking water, waste fluid processing, cooling tower pH/orp control, metal plating make up solutions, and boiler treatment additives.

  • Harwil CF-8/1G Chemical Feed Pump Controller

    Manufacturer Series
    Harwil CF-8/1G

    Harwil® type CF-8/1G one gang chemical feed pump controllers are stand alone interface modules that automatically actuate a chemical feed pump when primary bulk fluid begins to flow. These modules can be used in isolated stand alone systems or as part of large complex systems. Typical uses are for monitoring fluid flow in air conditioning systems, cooling in data centers, chillers, fluid blending systems, natural gas, industrial refrigeration systems, pools & spas, scrubbers, and water treatment systems.

  • Harwil LC-1 General Purpose Pump Controller

    Manufacturer Series
    Harwil LC-1

    Harwil® type LC-1 provides a combination of any two Harwil liquid level switches and an electronic control module mounted in a weather-resistant box to create a ready-to-go system for the automatic filling or emptying of tanks or vessels. The system is composed of an electronic latching/unlatching control module, a NEMA 4 weather resistant box with two standard ½” seal tight flexible conduit fittings, and a secondary 10A SPDT relay output. Each system is provided with a complete, descriptive parts list and an installation and wiring diagram for both level switches and control module.

  • Harwil SDC-101 General Purpose Pump Controller

    Manufacturer Series
    Harwil SDC-101

    Harwil® type SDC-101 modules may be connected to monitor critical points in simple one pump systems or, in series, with pumps, heaters, valves, etc., so that failure of any part will shut the whole system down. They are typically used in chemical processing, food processing, water treatment, agriculture, sanitation, aerospace ground support systems, mining, and transportation. They feature continuous adjustment of the time delay cycle.
