MAH2024H-2060H (2-Stage Cooling)

General Description

The Marvair® MAH family of wall mounted heat pumps are the ideal HVAC system for a wide variety of applications. The exterior mounting means that no valuable interior space is required. Marvair MAH heat pumps are packaged units – the refrigerant piping and internal wiring are factory assembled and thoroughly tested. All components are readily accessible for easy service and maintenance. The energy efficient operation keeps operating costs to a minimum and makes the Marvair heat pumps ideal problem solvers for a wide variety of applications, including offices, classrooms and telecommunication shelters.

MAH Single Stage Models

Marvair heat pumps meet all federal efficiency requirements with an Energy Efficiency Ratio (EER) of 11. Single stage Marvair MAA heat pumps are available in cooling capacities of 1½, 2, 2½, 3, 3½, 4 & 5 tons (20,000 to 60,000 BTUH).

Outside Air for Ventilation or Free Cooling

A full range of accessories and options allows the Classic heat pumps to be optimized for each application. For classrooms, a complete range of ventilation options are available to meet the fresh air requirements of the ASHRAE 62 standard, “Ventilation for Acceptable Indoor Air Quality”. Where cooling is required during cool or cold weather, e.g., telecommunications shelters, a factory installed economizer can be used. To insure proper operation and optimum performance, all outside air ventilation packages are non-removable, factory installed and factory calibrated.

Quiet in the Classroom

In addition to high efficiency, MAA heat pump models minimize sound levels in the classroom. A high efficiency axial fan moves air silently through the outdoor coils. A low vibration, scroll compressor insures quiet operation as well as energy efficiency. The indoor air mover utilizes a revolutionary electronically commutated motor (ECM). This motor consumes a minimum of power with whisper quiet operation.

Dehumidification

The introduction of outside air can cause humidity levels to rise to unacceptable levels. To reduce humidity, the Classic heat pumps can be ordered with humidity control at a minimum of expense.

Safety Listed and Energy Certified

All Marvair air conditioners conform to UL/CSA standard 60335-1 and 60335-2-40 and CAN/CSA C22.2, No. 236-11 Ed.4. For energy efficiency and performance, the units are tested and rated in accordance to the current ANSI/ARI (Air-Conditioning and Refrigeration Institute) Standard 390 (Single Package Vertical Units). All units meet or exceed the efficiency requirements of ANSI/ASHRAE/IESNA 90.1.2010. Marvair MAA heat pumps are commercial units and are not intended for use in residential applications.
