Marvair products

Marvair's MAH and MGH series air conditioners are specifically designed for vertical exterior wall mounting in electronic and communication equipment shelters, where consistent cooling is essential due to high internal heat loads. These units maintain operation even at external temperatures below 60°F (15°C) and utilize environmentally friendly R-454B refrigerant. The MAH models can include a factory-installed economizer that leverages outside air for cooling when conditions permit, which enhances temperature control, reduces energy costs, and augments the system’s reliability by lessening compressor and condenser fan usage. Compliance with UL/CSA 60335 standards and ANSI/ARI performance benchmarks assure users of their energy efficiency and safety. Notably, these commercial-grade units, which boast an EER of up to 11.5 and cooling capacities from 1.5 to 15 tons, are unsuitable for residential needs. Various accessories can be integrated for tailored performance.

The Marvair MGH series of vertical exterior wall mount air conditioners are specifically engineered to provide efficient cooling solutions for electronic and communication equipment shelters. These units are designed to manage the high internal heat loads frequently observed in such environments, with capabilities to operate effectively even when external temperatures fall below 15°C (60°F). Employing the non-ozone depleting R-454B refrigerant, the MGH series offers environmental consciousness alongside performance. An optional factory-installed economizer allows for cooling via outside air, enhancing temperature control and reducing energy costs while extending the life of cooling components. Built to meet stringent safety and efficiency standards, the air conditioners comply with UL/CSA 60335 standards and ANSI/ARI Standard 390. Capable of cooling capacities ranging from 90,000 to 180,000 BTUH (7.5 to 15 tons), the units feature dual compressors for high efficiency and reliability, fulfilling the demanding needs of commercial applications.

The Marvair GAH Series comprises advanced wall-mounted air conditioners integrated with gas heat, tailored for diverse settings such as modular classrooms, relocatable offices, and various permanent buildings. These units come in two cabinet sizes, offering nominal cooling capacities ranging from 2 to 5 tons and heating inputs from 45,000 to 125,000 BTUH. Designed with energy efficiency and safety in mind, the GAH units comply with UL/CSA standards, ANSI/ASHRAE/IESNA 90.1.2010, and are ANSI/ARI Standard 390 rated. Their construction allows for both factory and field-installed options to optimize usage per specific applications. Not intended for residential use, these air conditioners are characterized by an EER of 1100 and boast 80% heating efficiency. Technological features include a patented tubular heat exchanger, inshot gas burners, and a direct spark ignition system with LED diagnostics, ensuring reliability in performance and ease in both installation and service.

The Next Generation Scholar 2.0 VDH and VAH heat pumps and air conditioners are modular HVAC systems designed to provide heating, cooling, and outside fresh air for school classrooms. The units are installed in the classroom against an exterior wall. The vertical configuration minimizes the floor space occupied by the HVAC unit. This unique design makes it ideal for both new schools and for renovation of existing classrooms.
