LONE STAR Cold Storage

Location: Richardson, Texas
Industry: Cold Store/Food Distribution Center
Challenge: Large temperature differentials, constant ice build-up, doors jamming, high traffic flow
Door Model: TNR model HDT, High Traffic Doors


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 subfreezing 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 need to be included in the order for proper operation of the door are:

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