Custom Configuration For A University Laboratory

This custom XVC unit was built so that the customer, a university laboratory complex, could provide their own exhaust air blower section. Unlike most XVC units, which have exhaust air inlets on the bottom and exhaust air outlet sections on top, exhaust air enters this unit through one of its sides and passes straight out the other. In this airstream, XeteX only provided the exchanger and dampers. On the supply side, however, XeteX built the unit with cold water and steam coils, final filters, dampers, actuators, an air foil plenum blower, and a humidifier section. When finished, this unit gave the lab operators complete control over temperature and humidity, year-round energy recovery, and a custom configuration that met their requirements.
