Our equipment is suitable for any cryogenic processing application.

  • Industrial – Carbide and steel tools, bits, dies, and industrial diamonds.
  • Transportation – Engine blocks, springs, drums, rotors.
  • Marine – Engine components, racing props, shafts, and screws.
  • Electronics and Audio Equipment – Circuit boards, wires, and other components.
  • Musical Instruments- Treated instruments can improve octave ranges and durability.

 How Our Machines Workdeep cryogenic treatment machine

The goal of any cryogenic processing is to optimize the crystalline structure of your materials by getting them to cryogenic (-244°F or below) temperatures. Most processors accomplish this with a spray bar, which can lead to thermal shock, damaging your equipment.

Our cryogenic treatment equipment uses an internal heat exchanger in a vacuum insulated Dewar to give you even, controlled results for consistent output. Three different sizes give you the ability to choose the right tool for the right job, each with our leading-edge research built in.


Vacuum Insulation

Vacuum insulation greatly reduces heat penetration and keeps processing costs low.

  • Long-lived, permanent vacuum insulation is the best for your bottom line.There’s no compressor pump to fail, material to degrade, or internal structural support to transfer heat. Reliability and efficiency are built in. Our first vacuum insulated machine is still in service, several machines are still going after decades of use, and if the seal ever does break, it is easier and cheaper to repair than any insulation substrate.
  • The most efficient machines available. Due to our innovative design and the even cooling afforded by our round chamber, our cryogenic tempering equipment has the lowest use of liquid nitrogen of any available machine on the market.

  • The patented heat exchanger technology minimizes thermal stress and shock. Our heat exchanger uses a totally dry process; no spray bars to spray liquid nitrogen on the payload.
  • Heating element allows tempering right in the machine. You can precisely control the temperature range from -315°F to +320°F. This translates to lower costs, more control over the cycle, and the ability to temper parts in the machine. This means no additional tempering oven is necessary, providing you considerable savings and flexibility.
  • Microprocessor based industrial temperature control stores multiple programs.  This unit is meant for industrial settings.
  • Paperless electronic chart recorder makes a permanent record of every run. It tracks the temperature that the control is asking for, the actual temperature inside the processor and the temperature of the part being processed.
  • We have cryogenic treatment equipment in service worldwide. When we say we are a global authority on cryogenic treatment equipment and processing, we mean it. Please note: export versions are slightly higher due to modifications needed to adapt to different electrical currents, and to cover other costs associated with export.
  • Our machines are backed by a one-year warranty. For a period of one year after delivery, the manufacturer will supply replacement parts and repair instructions to remedy any defects in workmanship or materials, at no cost to the customer.


deep cryogenic treatment machines specifications

*Dead Weight is the weight of the interior of the machine that needs to be brought down to liquid nitrogen temperatures during the process and is therefore related to nitrogen consumption.
**Liquid Nitrogen Use is the amount of LN2 needed to keep the machine at -300F and overcome heat gain from the outside.
***Zero Load Nitrogen Usage is the amount of liquid nitrogen to run a cycle for an empty machine (no payload) on a cycle which consists of an eight hour ramp down to -300F and a twenty hour hold at that temperature.  To calculate nitrogen usage for the machine being run with a payload, add 0.25 liters of liquid nitrogen per pound of steel payload to this figure.
Note 1, Weight Capacity
We find that our cryogenic tempering machines are able to process virtually any load that can be placed in them, assuming there is some space in the machine for air to circulate around the load. The CP-1200vi is designed for and can easily accommodate loads of 3000 lbs. We routinely put loads of 2500 lbs. in CP-500vi’s

We occasionally have used equipment for sale.
