Why perform deep cryogenic treatment?

  • To increase the wear life of mining, energy and construction equipment by 30%

what we do

  • We manufacture, lease and sell deep cryogenic treatment equipment

  • We perform applied research to support our customers

The Deep Cryogenic Treatment process

Deep cryogenic treatment (DCT) is a -320°F (-196°C) cold treatment process that permanently reduces wear, fatigue and corrosion by 20-40% (see DCT Mining). The process works by placing items in an insulated chamber. Liquid nitrogen is slowly introduced via copper coils using a computer control with feedback loops. The chamber temperature drops slowly as latent heat is removed by thermodynamic exchange. Once the desired temperature is reached the items remain in this low entropy state before gradually returning to room temperature. During this process, the liquid nitrogen transforms back into a gas and returns to the atmosphere, where it comprises 78% of the air we breathe.  DCT takes 24 hours to complete. The process is low cost and highly effective. The deep cryogenic process is infinitely renewable and infinitely recyclable™ - an environmentally sound choice.

Although popularized by consumer use, deep cryogenics has its greatest impact extending the wear life of mining equipment such as:

Cone crusher mantles, liners and wear parts

slurry and paste pump castings

Shovel and bucket teeth

Shovel and bucket teeth

When and where to Perform Deep Cryogenic Treatment

Mining wear parts are usually castings made from 13 - 22% manganese, high chrome white iron or high carbon steel alloy. They are supplied by OEM’s, casting facilities or casting re-sellers. DCT is best employed just before customer use. The best location for a DCT facility is at or near a mine site or marshaling yard - taking advantage of the low cost process to improve multiple types of wear parts at the same time - like jaw and cone crusher mantles/liners, shovel and bucket teeth, gears and conveyer items. Although there are different treatment recipes to optimize different alloys, often a single recipe will capture 80% of the available improvement.

So Why has DCT escaped mainstream attention and acceptance?

  • no test, validation or certification procedures — until recently

  • no manufacturer of industrial size DCT equipment — until recently
