Primarily used to cool industrial equipment such as communication shelters, relocatable offices, electrical switchgear stations, control rooms, and pump stations, Marvair ComPac I and ComPac II air conditioners have been engineered for use in both mobile and fixed building applications and are ruggedly engineered for use in a wide range of designs and applications.
Every ComPac unit is designed for operation up to 120ºF with low ambient control standard on every unit to 20ºF. If additional extremes are necessary, units may be configured with our "Desert Duty" option pushing operation up to 131º or an "Extreme Duty" package that will allow units to cool all the way down to -40ºF.
The ComPac line consists of 4 different efficiencies based by series.
AVPA - Standard Efficiency Models
The Most popular series meeting the U.S. governments minimum energy efficiency standards of 9.0, these units come with an Energy Efficiency Ratio (EER) between 9.0-10.0. Cooling capacities of 1, 1.5, 2, 2.5, 3, 3.5, 4, 5 and 6 tons (12,000 BTUH to 72,000 BTUH) are available.
AVHA - High Efficiency for the States with 10 EER minimums (Alabama, California, Hawaii, Illinois, Maryland, Massachusetts, New Jersey, New York, Texas, Utah, Vermont, and Washington state.) Available in 2, 2.5, 3, 3.5, 4 and 5 tons (24,000 BTUH to 60,000 BTUH)
HVEA - Ultra-high efficiency 10.5 - 11.75 EER. Soon this will be the US Standard Efficiency available as 2, 2.5, 3, 3.5, 4, and 5 tons (24,000 BTUH to 60,000 BTUH)
HVESA - Step Capacity (most effecient) 2-staged compressors 14.0-16.0 Integrated Part Load Value (IPLV).
Staged compressors operate in steps, the First stage will operate at about 65% of the compressor's capacity. This can help when equipment requires lower start-up amps when running on a generator. 2-staged compressors also operate more efficiently, precisely matching heat loads with the right cooling capacities.
