Bulkheads and Dividers For Multi-Temp Trailers

Load Dividing Bulkhead Types, Options, and Varying Product Volumes

Bulkhead in a single-temp operation typically refers to the air-return bulkhead on the front wall behind the refrigeration unit. But in a multi-temp trailer bulkheads and dividers operation, the term bulkhead refers to the insulated divider between zones. And there’s a whole book of options you can use.

Bulkheads can be customized to include:

• Different securement systems (floors, walls, ceilings)
• Trollies for moving trailer bulkheads and dividers
• Varying heights for wedge-type trailer designs
• Vents or Fans to transfer volumes of air from one zone to another
• Access doors to allow the driver to access each zone

How to Extend your Zones to the Rear Door

The Roll Door Cavity:

A roll door cavity is a false ceiling that allows you to extend zones and minimize heat gain.

The false ceiling sits a few inches below the rollup door track and provides a flat solid surface for which you can install a bulkhead just in front of the roll door. This accomplishes two things:

1. • Extends your zone 2, or zone 3
   • Provides further protection against heat gain or temperature loss through a roll door which is notorious for being inefficient

Battling Heat Gain at the Rear Door

The Utility Barrier® Door Design

Nothing is as efficient as a Utility swing door (Barrier® Doors); they don’t have heat gain problems. But any roll door has hinges, joints, and bush seals, and you’ll gain heat and lose temperature control around a roll door. So you want to consider the roll door cavity with false ceilings.
