Upblast Plenum AirPak System

On the AirPak product line, the upblast plenum works in the same manner as that on the InPac line, by rotating the blowers to the move air through the top of the cabinet into a plenum that typically connects to ductwork higher in the building.

Roof Mounted InPac Systems

Specific Systems roof mounted InPac systems are typically horizontal in design. The systems are mounted to a skid, and our engineering team will work with you to meet the specifications of the roof curb on your building. The supply and return can be independently arranged prior to manufacture to meet the needs of the application to flow through the end, sides, or bottom of the industrial HVAC system.

Pad Mounted InPac System

As one of our most popular options, pad mounting is best used on permanent structures and when wall space is at a premium. The included duct mate flanges help minimize wall perforations and let you choose points of entry that meet the requirements for each building individually, which works even better on the larger 35-50 ton unit sizes.

Cabinet Coolers

As more and more electrical equipment becomes packed into smaller enclosures, the heat generated inside those enclosures rises. That heat can cause process shutdown through tripped overloads or worse, damage to the equipment. In some critical applications, downtime can cost thousands of dollars per hour.

AirPak Reverse Airflow

As with the InPac line, our AirPak reverse airflow configuration moves the return air to the top of the unit, while the supply air is relocated lower in the cabinet. This configuration can help maintain dynamic airflow in the enclosure since heat naturally rises. In high heat load applications like VFD buildings, much of the heat is exhausted through tops of the enclosure, with cool air designed to be drawn in from the bottom of the process controls inside the building.
