In this series of articles, we'll discuss Trailer Body Features and Upgrades you'll want to consider when spec'ing your next reefer trailer.
Today we’re talking about Insulation, Light packages, and Stainless Steel options.
What Thickness Insulation Do I Need For My Reefer Trailer?
More insulation means greater ability to hold temperatures, and more insulation means thicker walls, which reduces interior space.
Common insulation thicknesses:
- 2” on the side
- 3” on the roof
- 3” in the floor
- 4” on the front wall
- and 3' in rear doors
When you have a High Cube or Deep-Frozen situation, we’re either adding to the insulation or removing from it.
- Insulation thickness affects resale value.
- Adding insulation decreases interior dimensions affecting loading capacity and the ability to haul specific product types.
- If you’re going to keep this trailer for twenty-five years, you might want to add 5” of insulation, but if you’re going to keep it for seven years, you’ll take a significant hit when you go to sell it because interior dimensions are not standard.
Building your reefer trailer with thin insulation in walls, ceiling, and floor can increase interior space.
Thin insulation will require a higher BTU reefer unit.
- Going to thin insulation requires a greater cooling capacity reefer unit - higher BTUs. It’s wise to do this because you are cutting back on your thermal efficiency with thin insulation.
- And, this will allow you to still haul the deep frozen.
Light Package Options For Reefer Trailers.
- Do you load or unload at night?
- Do you want ceiling lights?
- If you’re loading at night, you’ll need interior lighting to keep drivers and dock workers safe and make reading easier.
- Trouble-free and long-lasting Light-Emitting Diodes (LEDs) produce a white light that spreads throughout a trailer's interior.
- LEDs are installed in 90 percent of new refrigerated trailers.
Many times brighter than incandescent and fluorescent lights, high output LED lights have lower current draw, increased life, and operate equally well in high and low temperatures.
The number and combination of lights is a personal preference, though the most common light package is 2-5-6-5.
- Bare minimum up to 11 lights per side, top, and bottom rail.
- Minimum "standard" is (2-0-1-5): (2) on Front, (0) on Top Rail, (1) on Bottom Rail, (5) on Rear
- Maximum is (2-11-11-5)
