OVERVIEW
#
RV/RVE

Pre-engineered rooftop ventilators condition and deliver 100% outside air or mixtures of outdoor air and return air to a building. This unit is ideal for 100% outdoor air, variable air volume and single zone applications.

  • 800 to 18000 cfm
  • Up to 3 in. wg (ESP)
  • 5 to 70 tons cooling capacity
  • 100 to 1,200 mbh heating capacity
  • Cooling options: packaged direct expansion, chilled water, air-source heat pump, and split direction expansion with or without remote condenser on select models
  • Heating options: indirect gas, electric, and hot water

The RV/RVE offers several value-added features. These include a microprocessor and direct drive plenum fan(s) with variable frequency drives (VFDs).

  • Energy recovery wheel for superior energy savings (RVE)
  • Inverter compressor for increased part load efficiency
  • Web user interface with microprocessor controls
  • Modulating hot gas reheat
  • High turndown furnace up to 16:1 (patent pending)
  • Recirculation damper
  • Low sound condenser fans on select models
  • Electronically commutated motor or VFD on the lead condenser fan

ERCH

The ERCH combines the benefits of the total energy wheel with supplemental cooling and/or heating. The result is a product that is specifically designed to condition 100% outdoor air to desired supply conditions. Model ERCH offers a wide variety of configurable options from intake and discharge orientations to factory tested and proven control sequences.

  • 1,000 - 10,000 cfm
  • Up to 1.75 in. wg
  • Cooling options: packaged direct expansion, split direct expansion, chilled water, water-source heat pump, or evaporative cooling
  • Heating options: indirect gas, electric, hot water, or water-source heat pump
#
ERT

Model ERT offers the benefits of a total energy wheel and cooling coil with a wrap-around heat pipe and/or heating. The result is a unit designed to be the most efficient product for conditioning humid outdoor air to near room conditions.

  • 2,000 - 10,000 cfm
  • Up to 1.75 in. wg
  • Cooling options: split direct expansion or chilled water
  • Heating options: electric or hot water
