Drive in with forklift truck with four 600 lbs. 55-gallon drums on a single pallet (could have been a 600-gallon tote tank). Forklift goes straight up ramp and on back to rear wall to set load on grated elevated flooring and reverses straight back out. Returns with another load to be set on top of the first pallet, and so on, until there are pallets lined up front to rear five deep and two high.

Next, the forklift starts another row of pallets to complete two rows of pallets, for a total of ten pallets, or forty 55-gallon drums per each 9′ wide x 8′ high door opening, or a total of twenty pallets (80 drums) under refrigerated storage in this 20′ deep room. Overhead doors are up to 3-hour fire rated and 180 mph wind load capable and R-7 insulated – all U.L. classified.

Vinyl curtain slats reduce loss of treated interior air during loading and unloading. Grated ramp floor reduces dirt being tracked into building and snow and ice build-up.

County Morgue refrigerated (45°F) Incoming Chemical Storage Room placed in corner of existing garage.

“First in, first out” freezer with forklift at “in” door sending pallets down rollers to stop at “out” door. See close in photo next right.

Personnel door allows entry to inspection aisle left of yellow safety rail. Vertical side rollers prevent pallets from jamming as they roll down sloped horizontal rollers.

Cold and hot box (14°F and 212°F) R-30 insulated doors inside with 4 HRFR dropdown shutters. Flashing at base can be installed after installation.

  2. At what temperature is the product coming into the building?
  3. How much product, on average, is brought into the building per hour, day, week, ect.?
  4. What temperature do you want to maintain?
  5. How fast do you need the product to be pulled down to optimum temperature?

Combination Haz-Safe walk-in refrigerator and freezer chemical storage building in corner of user’s warehouse. Building designed as a two-unit modular building with each half passing through exisiting facility’s small entrance, rolled to above location and put together with patented modular bolt-up hardware. Below is a close-up of what’s seen in open door.

Hazmat refrigerator/freezer building has R-30 insulated doors, floors, walls and roof with staggered tubular steel wall members providing thermal breaks. Refrigeration systems are designed to maintain 45°F in refrigerator room and -12° F in the freezer room. The building is 2-hour fire and 150 lbs feet squared blasted rated. Picture below is close-up of what’s seen from open door.

User has stored chemical boxes stacked up in refrigerator room. Hanging from ceiling near back wall is the air handler evaporator unit. The beam-like “bump” on the ceiling is part of the fire rated joint between the two modular units that make up the bolted together building.

Larger air handler/evaporator unit is required in the freezer room. Fewer user stored boxes exposes more of the porcelain enameled steel interior finished walls and ceiling. There is a painted steel sump floor joint cap dividing the elevated grated floor of the two modular units.
