Custom ERV with High Plume Exhaust Fans

This XeteX project features a custom energy recovery ventilator with an aluminum flat plate heat exchanger for a pharmaceutical manufacturer.

Lab ERU with High Plume Exhaust Fans

This Custom ERV services a lab space where precise control of the temperature and humidity are critical. Due to the high amount of outside air and tight range of delivery conditions required, XeteX employed the following design strategies to ensure reliable desiccant dehumidification year round:

  • Variable speed inverter tandem Scroll compressors
  • Low ambient condenser kit
  • 10:1 Indirect gas fired heater
  • Short absorption steam humidifier manifold

Another noted feature on this unit was the high plume lab exhaust fans. These specialized exhaust fans were provided by the rep and field installed on our pre-engineered mounting curbs with pre-wired electrical connections.
