• The award-winning 3fficiency system has been receiving industry recognition for providing an energy-efficient, easy-to-specify integrated system. 3fficiency uses an average of 70% less pump energy to achieve better comfort than traditional equipment. The system also reduces airflow by 50% or more, saving motor horsepower. 3fficiency improves upon a traditional chilled beam design by reducing piping and simplifying building controls.


    3fficiency consists of three top of the line SEMCO products:

    • Pinnacle Dedicated Outdoor Air System: Manages 100% of a building’s ventilation and indoor humidity load in a single package, responding to varying conditions on demand. It cools, heats, or dehumidifies as required, providing a steady stream of optimally pre-conditioned, high quality comfortable air. 
    • NEUTON Controlled Chilled Beam Pump Module: Designed to control condensation, provide energy savings, and optimize water temperature.
    • SEMCO Active Chilled Beam Line: Provide comfort with low air velocities in the room by mixing the supply air with the ambient air

    3fficiency is a great alternative to Variable Refrigerant Flow (VRF). The benefits of using 3fficiency over a VRF system include:

    • No more concerns with ASHRAE 15 – Safety Standard for Refrigeration Systems
    • No more refrigerant leaks
    • No large electrical wire runs
    • A whole building variable water flow system!
