Heat Pumps

Whether for a new school, a modular classroom or a school renovation project, Marvair has a heat pump ideally suited to your needs and budget.

All Marvair packaged heat pumps are tested according to ARI standard 390, "Performance Rating of Single Package Air-conditioners and Heat Pumps", and listed in the AHRI Single Package Vertical Units (SPVU) directory. ARI standard 390 is a product classification developed by ASHRAE 90.1-2010 and the Air Conditioning Heating & Refrigeration Institute (AHRI).

The classifications - SPVAC for air conditioners and SPVHP for heat pumps - are referenced in the ASHRAE standard 90.1-2010. ARI standard 390 determines cooling efficiency as EER and heating efficiency as COP. All certified ratings for performance and efficiency are according to ARI 390. Performance minimums for SPVU's in ASHRAE 90.1-2010 can be found in table 6.8.1.D. A detailed description of the reasons that ARI created a new standard for our equipment can be found in the ARI 390 Marvair Sales and Marketing Notice dated 4.06

HVPA and HVPSA Exterior Wall Mount Heat Pump

Marvair Classic Heat PumpsMarvair® HVPA and HVPSA 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 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.

HVPA High Efficiency Models:

  • EER: 11.00 - 11.50
  • Cooling Capacities: 2, 2½, 3, 3½, 4 and 5 tons (24,000 BTUH to 60,000 BTUH)

HVPSA 2-Stage Compressor Models:

  • EER: 11.00
  • IPLV: 13.6 - 15.0
  • Cooling Capacities: 2, 2½, 3, 3½, 4, 5 and 6 tons (24,000 BTUH to 60,000 BTUH)
  • 2-Stage Compressor: First stage cooling is approximately 65% of the total cooling capacity. The 2-stage compressor provides lower start-up amps which can be critical when operating with a generator. The two stage compressor also reduces energy costs by more precisely matching its cooling capacity with the heat load in the shelter.
