In sizes 5 to 40 ton, the VPAX series is specifically designed to provide a safe, clean indoor environment for RIE and similar buildings containing computers and other sensitive electronics. As specified, the system provides either:
- Environmental protection with over-pressurization inside the building to prevent infiltration of corrosive gasses, or,
- Class I, Division 2 hazardous location positive pressurization of 0.1" WC (min.) to prevent infiltration of hazardous and corrosive gasses and reduce the classification inside the building to an ordinary (non-hazardous) location.
Featuring two air conditioning units for full redundancy, the VPAX incorporates cooling, heating, and dual pressurization with gas-phase air filtration into a single system. The VPAX is designed to allow for easy installation and maintenance. The complete assembly is designed for installation on the exterior of the building. Only the control section with supply and return air openings penetrates the building making for a minimal wall cutout. Structural support underneath the VPAX is required to be provided by the customer.
