Marvair ComPac Telecom HVAC

General Description

The Marvair® ComPac® I and ComPac® II air conditioners are used primarily to cool electronic and communication equipment shelters. Due to the high internal heat load, these shelters require cooling even when outside temperatures drop below 60°F (15°C).  The ComPac I and ComPac II air conditioners have the necessary controls and components for operation during these (less than 60°F [15°C) temperatures. All models use the non-ozone depleting R-410A refrigerant.

The primary difference between the ComPac I and the ComPac II units is that the ComPac® II air conditioner has a factory installed economizer. When cool and dry, the economizer uses outside air to cool the shelter. The economizer provides temperature control, energy cost savings, and increased reliability by decreasing the operating hours of the compressor and the condenser fan. The ComPac I and ComPac II air conditioners are problem solvers for a wide range of conditions and applications. To insure proper operation and optimum performance, all economizers are non-removable, factory installed and tested. In addition, factory and field installed accessories can be used to meet specific requirements.

➤ AVPA Standard Efficiency Models

  • EER: 9.0 - 10.00
  • Cooling Capacities: 1, 1.5, 2, 2.5, 3, 3.5, 4, 5 and 6 tons (12,000 BTUH to 72,000 BTUH)

➤ AVHA High Efficiency Models

  • EER: 10.0
  • Cooling Capacities: 2, 2.5, 3, 3.5, 4 and 5 tons (24,000 BTUH to 60,000 BTUH)

➤ HVEA Ultra High Efficiency Models

  • EER: 10.5 - 11.75
  • Cooling Capacities: 2, 2.5, 3, 3.5, 4, and 5 tons (24,000 BTUH to 60,000 BTUH)

➤ HVESA 2-Stage Compressor Models

  • IPLV: 14.0 - 16.0
  • Cooling Capacities: 3, 3.5, 4 & 5 ton (36,000 BTUH-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.

Safety Listed and Energy Certified

All ComPac air conditioners are built to UL standard 1995, latest edition and CAN/CSA C22.2, No. 236-11. 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. The ComPac I and ComPac II air conditioners are commercial units and are not intended for use in residential applications.

Standard Features

  • Designed for Operation in Low Ambient Conditions
  • Low ambient control cycles condenser fan to maintain proper refrigerant pressures.  Allows operation in mechanical cooling (compressor) of our standard air conditioners down to 20°F (-7°C). With the Extreme Duty option, the units will operate down to 0°F (-18°C). Note: low temperature operation is affected by ambient conditions, e.g. wind and humidity
  • Three minute by-pass of the low pressure switch for start-up of compressor when outdoor temperatures are below 55°F (13°C)
  • Factory built-in economizer (ComPac II models only)

High Efficiency

  • High efficiency compressor
  • Lanced fins standard on all evaporator and condenser coils

Built-in Reliability

  • High pressure switch and low pressure switch with lockout protects refrigerant circuit
  • Adjustable .03 to ten minute delay on make for short cycle protection
  • Remote Alarm Capability
  • Dry contacts can be used for remote alarm or notification upon air conditioner lockout

Ease of Installation

  • Sloped top with flashing eliminates need of rainhood
  • Side access panels on economizer equipped models for easy access to electrical connections
  • Built-in mounting flanges facilitate installation and minimize chance of water leaks
  • Supply and return openings exactly match previous models
  • Factory installed disconnect on all units
  • Single Point Power Entry complies with latest edition of U.L. Standard 1995

Rugged Construction

  • Copper tube, aluminum fin evaporator & condenser coils
  • Field or factory installed heaters on discharge side of evaporator coil (optional)
  • Baked on neutral beige finish over galvanneal steel for maximum cabinet life (Other finishes are available)

Ease of Service

  • Service access valves are standard
  • Standard 2” (50 mm) pleated filter with a MERV rating of 8 changeable from outside
  • All major components are readily accessible
  • Front Control Panel allows easy access and complies with NEC clearance codes on redundant side-by-side systems
  • LEDs indicate operational status and fault conditions.
  • Foiled backed insulation on the indoor air path.
  • A minimum position potentiometer that can be adjusted to prevent the economizer damper from closing completely. This control ensures that whenever the evaporator fan is operating, fresh air is being introduced into the building.
