Greenheck today announced the expansion of its packaged rooftop ventilation line with the addition of Model RV(E)-120, a pre-engineered system featuring increased performance capabilities for larger dedicated outdoor-air systems, multizone variable-air-volume (VAV) systems, and single-zone VAV systems.
Model RV(E)-120 features 2-in. R13 foam-panel construction and thermally broken design. Its low-sound condenser fans are an average of 5-dB to 10-dB quieter than standard condensing fans, while dual supply and exhaust fans deliver improved performance and reduced unit electrical loads. Four independent cooling circuits, meanwhile, allow for excellent cooling turndown and control.
On indirect gas-fired furnaces, 10:1 modulating turndown is achievable for increased operating performance.
Model RV(E)-120 provides performance capacities of up to 12,000 cfm, up to 45 tons of cooling, and up to 800-Mbh heating.
