FV TS Preconditioner

  • The SEMCO FV-TS Series of outdoor air pre-conditioners has been specifically designed to reduce the energy required to heat or cool outdoor air by up to 80 percent. The FV-TS pre-conditioner allows the HVAC system to effectively and economically accommodate the three-to-four-fold increase in outdoor air quantities that is recommended by ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality. This unique capability allows both new and existing buildings to benefit from a healthy indoor environment.


    An FV-TS pre-conditioner will significantly reduce the operating cost of the HVAC system of a facility designed in accordance with the ASHRAE IAQ standard. It will also improve humidity control when combined with unitary heating and cooling equipment. Because the FV-TS preconditions the incoming air to the packaged equipment, the required refrigeration capacity may be reduced by as much as 50 percent. Thus, the cost of the pre-conditioner and its installation are typically offset by the reduced size of the conventional HVAC system.


    In existing facilities, retrofitting the HVAC system with an FV-TS pre-conditioner allows the outdoor air quantity to be increased significantly without raising energy costs, losing humidity control, or changing the size of the current HVAC unit.
