Rooftop Units

Exhaust-recovery ventilator
The EnergyX energy-recovery ventilator (ERV) is now offered as a fully integrated, factory-installed option on WeatherMaster 48/50 HC rooftops units. The ERV pre-conditions outdoor air before it enters the rooftop-unit evaporator coil and uses building exhaust air as a heat-exchange source. It operates efficiently under a wide range of ambient temperatures. The EnergyX system achieves a combined efficiency factor (CEF) of up to 17.0 and offers the potential to reduce costs by downsizing the base rooftop unit while still meeting ventilation requirements. —Carrier

Packaged unit with hot-gas reheat
The Series 10 single-packaged unit combines efficiency ratings of up to 15 SEER and ease of installation in a light-commercial unit. A hot-gas-reheat option efficiently reuses hot gas from the cooling cycle to allow for dehumidification without increasing sensible cooling and without the need for electric or gas heating. —Johnson Controls

Packaged rooftop units
RQ Series packaged rooftop units feature a double-wall, rigid-polyurethane-foam-insulated cabinet and direct-drive,backward-curved plenum fans to allow quiet, energy-efficient airflow and high static-pressure capabilities. RQ units are available as air-cooled-condenser packaged rooftop units; air-source, water-source, or geothermal heat pumps; 100-percent-outside-air units; and chilled-water or non-compressorized air handlers. Heating is available in hot-water, steam, electric, and gas-heating configurations. RQ Series units are available in capacities from 2 to 6 tons. —AAON

Integrated air and water system
Designed for full-service restaurants, the H2AC packaged rooftop unit with eSync Integration Technology provides an integrated air and water solution by delivering air conditioning and water heating from a single source. The unit uses the heat from an HVAC system that normally would be rejected into the atmosphere to heat water by switching from a refrigerant-to-air system to a refrigerant-to-water system when a restaurant has demand for air conditioning and hot water. —Rheem

Packaged gas/electric units
CPG 6- to 20-ton packaged gas/electric units are designed to provide uncomplicated installation options and efficient cooling in an easy-to-service unit. The units are delivered with lugs, full-perimeter rails, and standard 2-in. filters. They feature single-point service access, Goodman’s TuffTube tubular heat exchanger, a high-efficiency scroll compressor, copper tube/aluminum fin coils, R-410A refrigerant, a high-capacity steel-cased filter dryer, and a UV-resistant powder-paint finish. CPG units are covered by a 20-year limited warranty on the heat exchanger and a 5-year limited parts warranty. —Goodman

Exclusive fan technology
The Energence line of 3- to 50-ton rooftop units combines efficient performance with the intelligent Prodigy control system, standard on every unit, to achieve a low total cost of ownership. Lennox’s exclusive multi-stage air volume (MSAV) supply-fan technology, factory-installed on 7.5- to 25-ton units, helps to reduce energy use and dramatically lower energy costs. The MSAV supply fan uses a patent-pending variable-frequency drive to lower airflow during part-load cooling, heating, ventilation, and free-cooling modes. —Lennox

Gas packs for the retrofit market
R6GP Series packaged gas/electric 7.5 and 10-ton rooftop units are designed for the retrofit market. They fit most standard rooftop applications and can be adapted for exceptions or converted to horizontal airflow with a kit. The units feature a full-perimeter base-rail system with rigging holes and forklift slots on three sides. The three-phase units are rated at 11.2 EER and use R-410A refrigerant. R6GP models come with a one-year commercial parts warranty, a five-year limited compressor warranty, and a 10-year limited heat-exchanger warranty. —Mammoth
