Catch Up With TNR! Case Study: Lone Star Cold Storage

TNR Industrial Doors

We take pride in solving the challenges our customers face as we believe that satisfied customers are the best form of advertising.

A recent project we are particularly proud of was for a customer based in Richardson, Texas. TNR Doors was invited solve a unique door challenge where conventional doors had proven ineffective in cold storage facilities due to ice build up resulting in doors jamming up.

The solution? TNR’s high-performance durable HDT High Traffic Door!

Location – Richardson, Texas

Industry – Cold Storage / food distribution center

Challenge – Large temperature differentials, constant ice build-up, doors jamming, high traffic flow

Door Model – TNR model HDT, High Traffic doors

The Problem

Blast freezers provide a unique door challenge to rolling steel, overhead and even fabric doors. The temperatures are usually in the range of -10° F on the warm side to a sub-freezing temperature of -30° to -40° F on the cold side. These low temperatures are needed to ensure that the products remain frozen during transportation abroad. Unfortunately, such low temperatures also cause icing problems on conventional doors. The doors jam and ice builds up on the panels creating headaches and safety issues for the owner.

TNR Solution

TNR Industrial Doors can solve these difficult issues with their model HDT door. The door has a heavy duty low-temperature 0.25″ thick EPDM rubber curtain that is rated for continuous use at -40° to -50° F. The EPDM curtain remains flexible and straightens quickly to enter the guides during the closing cycle. Ice does not build up on this curtain the same way it does on conventional products.

Other items that needed inclusion in the order for proper operation of the door include:

  • A BMH rectifier to keep the brake warm and frost free
  • Synthetic oil and a heat probe in the gear box
  • A heater strip in the limit box and the wall mounted panel

Door Size & Quantity

Door Size (16′-0″ x 17′-0″), 4 doors.
