 Designed for Precedent

The new PrimAir return air bulkhead was designed to work perfectly with Thermo King’s new Precedent units. While the bulkhead is compatible with older Thermo King and Carrier® units, it has been optimized to deliver the best airflow possible from the Precedent unit.

Easier to Handle and Install

The new bulkhead design is narrower than previous and
competitive models, making it lightweight and easy to handle during installation and allowing for easier service access.

Maximizes Unit Efficiency

The new PrimAir bulkhead also has larger air inlets, which are shaped to reduce the amount of pressure drop seen across the bulkhead. This lower pressure drop means the refrigeration
unit works more efficiently – reducing fuel consumption and wear on the fans.

Easy Service Access

With the PrimAir™ bulkhead, servicing the evaporator is a whole lot easier. By simply unlatching the top half of the bulkhead, it can be lowered to provide access to evaporator, a highly practical design that saves on maintenance time.

Minimize Maintenance

Adding a debris screen to the return air bulkhead is a smart way to improve the efficiency of your refrigeration unit and reduce maintenance. By trapping plastic wrap and other debris before it gets to the evaporator coil, the unit runs more efficiently and the debris can be cleaned out without accessing the evaporator.

Exceptionally Durable

The PrimAir bulkhead is constructed of a thick polyethylene material. It is strong, durable, resistant to damage from the cargo and provides protection for the evaporator. The nonporous
material is easily cleaned and specifically approved by the FDA for contact with food products.

Universal Design

The PrimAir bulkhead fits all Thermo King and Carrier® wide post models. The support pod configuration provides contact points for attaching to the trailer front wall supports,
regardless of the trailer manufacturer. The bulkhead does not need to be attached to the evaporator itself.
