AAF-Herman Nelson

Model: Self-contained unit ventilator AZQ, AEQ, ARQ, ERQ, GRQ

Footprint (inches): Up to 110 (length) by up to 30 (width) by up to 29 (height)

Serviceability features: Two end panels provide access to piping, temperature control components, and the fan switch. Unlike units with full-length front panels, these can be removed without disturbing normal operation of the unit. Hinged top-access doors provide access into the end compartments to facilitate servicing of the motor, electrical, and refrigeration components. Center front panel provides access to the filter and fan shaft bearing.

Technical support: Through local representative and website.

Technical support materials: Pre- and post-sale marketing materials are found on website. Product data catalogs, installation/operation manuals, certified drawings, and much more available at www.mcquay.com/McQuay/ProductInformation.

Noise-reduction features: The GentleFlo™ air-moving system minimizes operating sound levels, even as demands for more fresh air require units to operate longer and work harder. Large fan wheels are wide and rotate at a low speed to reduce fan sound levels. They are impact resistant and balanced to provide consistent performance. Offset, aerodynamic fan wheel blades move air efficiently, and precision tolerances help reduce flow and pressure turbulence, resulting in lower sound levels.

IAQ equipment supported: Unit ventilators deliver fresh air to meet ventilation requirements, and added cooling capacity to maintain consistent comfort for students and teachers. Economizer operation, demand control ventilation (DCV), and part-load variable air options make it possible to match classroom comfort requirements more closely, thus reducing operating costs.

Thermostat compatibility: Compatible with most thermostats.

Replacement parts compatibility: Shares replacement parts with other models.

Additional features: Two-stage compressors stage from full- to part-load, or part- to full-load compression to meet the space temperature setpoint. The unit runs on lower fan speeds most of the time, improving comfort through better humidity control and quieter operation, while minimizing issues with oversizing. Water-source heat pump unit ventilators offer part-load efficiency for ground-loop applications in excess of 23 EER.

Warranty information: Standard factory warranty is 12 months from the date of installation or 18 months from shipment. Extended warranty options are available.

Special installation requirements: All units ship with detailed installation instructions.

Footprint (inches): 26 to 49 (length) by 34 (width) by 51 (height)

Serviceability features: From a service perspective, the Invictus is no different than a small condensing boiler. It has a fuel train, fiber mesh burner, blower fan, and a flue stack. The sealed system that contains the water-ammonia refrigerant solution does not require any maintenance.

Technical support: Available 24 hours a day, seven days a week at 315-298-5121.

Technical support materials: Available for download online or from local manufacturer reps.

Noise-reduction features: The sealed system is insulated, and overall operation of the unit is very quiet. The heat pumps are not installed in the ceilings of rooms or zones within a building; they are part of the mechanical room and, thus, are separated from building occupants.

IAQ equipment supported: This is a hydronic product, thus it produces hot or cold water. It is not an air-handling product. Units are incorporated into traditional hydronic heating-cooling applications.

Thermostat compatibility: Compatible with most thermostats.

Replacement parts compatibility: Shares replacement parts with other models.

Additional features: These gas absorption heat pump systems offer up to 149 percent thermal efficiency. The systems are appropriate for colder, heating-dominant climates and areas where electricity costs are high and cooling loads are low. When combining the units with hydronic boilers and effective control strategies, the result is a heating system that can operate at all ambient or system conditions.

Warranty information: One-year standard parts; sealed system containing the water-ammonia solution has a standard warranty of three years, extendable up to eight years.

Special installation requirements: Installation is easy because the Invictus units are hydronic; they are installed as part of a traditional boiler room. The units are piped primary-secondary (with a dedicated circulator pump), and water piping is connected into a new or existing hydronic boiler or chiller system. There is no need to retrofit ductwork and incorporate air-handling products that will require maintenance in the ceilings of various rooms or zones inside a building.
