KINROSS Tasiast Mine

TNR’s rubber roll up doors were chosen due to their tight door fit with minimal infiltration and the simple, yet effective operation in rugged conditions. The HDXL and HDC-DD have SBR rubber curtains with polyester core weave making the doors flexible but still resistant to abusive environments, even in the extreme temperatures of the Sahara Desert.

BAFFINLAND Iron Mine

TNR Industrial Doors was chosen due to their simple door design, ability to take an impact without door damage and TNR’s strong reputation, which is well known throughout the mining industry. TNR was able to meet Baffinland’s tight lead times for manufacturing the doors. Also, TNR was able to coordinate ocean freight to ship the doors directly to the mine site in order to have the doors installed by the winter deadline.

LONE STAR Cold Storage

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 the same way it does on conventional products.

BROADWIND TOWERS

Broadwind already had a very positive recent history with TNR doors in a blast booth application. The doors had proven to have a tight seal, were low maintenance and had the ability to withstand accidental impact. The heavy duty doors would accommodate the large equipment used to move tower sections in and out of the building. Broadwind’s concern about windload was quickly put to rest with TNR’s 90 mph rating. TNR’s heavy duty door construction and springless design were key features for the operations team.

Management’s initial apprehension for the cost of these large doors was allayed when safety risk and ROI was fully reviewed.

Oyu Tolgoi Mine

Such an extremely tall door is only available as a rubber roll-up door, a fabric door or a blade door. A large fabric door is just not durable enough in this rugged mining environment. A blade door, although very durable, requires a larger footprint and more maintenance. A TNR rubber roll-up door is a simple yet extremely durable design that can be built tall enough to accommodate these service doorways. Since 2006, Oyu Tolgoi has installed over 25 TNR rubber doors on many of its mine’s operations buildings where the doors have proven their reliability and long service life in a rugged environment.
