Marvair's ComPac
®
lines are a series of vertical wall-mounted air conditioning systems that
provide heating, cooling, and ventilation for electronic equipment shelters, process control
centers, and other applications with high internal heat gains. The series includes multiple
sizes and nominal cooling capacities from 18,000 to 72,000 BTUH. Resistance heating
elements are available in various wattages.
Marvair’s ComPac
®
I & ComPac
®
II air conditioners, models AVP20-60, feature an
exclusive electronic control board. The control board consolidates several of the electrical
components and improves the air conditioner’s reliability. The control board replaces the
blower relay, the lockout relay, the compressor time delay and the timed low pressure
bypass. In addition, the control board has LED’s to indicate operating status and fault
conditions to assist the service technician. A complete description of functions of the
control board is in Section 1.6. The AVP72 does not currently have the control board.
The ComPac
®
I & ComPac
®
II models are designed for easy installation and service. Major
components are accessible for service beneath external panels.
All units have internal disconnects (optional on 460V). Depending upon state and local code
requirements, this feature may eliminate the need for an external breaker or disconnect.
The ComPac
®
I A/C has a 0-15% manual outside air damper and the ComPac
®
II A/C has
a factory installed economizer for 100% free cooling with outside air.
