Through the employment of ultra-low temperatures, 300 Below, Inc. helps its customers improve all kinds of products by realigning the molecular structure of an object, optimally resulting in items which last significantly longer and perform far better than they were previously designed. Our proprietary process uses Deep Cryogenic Tempering, for which we have developed an advanced, computer controlled processing system for reliably treating materials used in multiple industries throughout the world. 300 Below specializes in the science of cryogenics and we engineer various liquid nitrogen (LN2) based cooling and freezing systems to perform what is termed as cryogenic processing.
As our company name implies, we treat metal components and parts at minus 300 degrees Fahrenheit to improve their properties. Computer technology allows us to regulate temperatures to 1/10th of a degree, accurately adjusting temperatures optimal for proper cryogenic treatment (or Cryo-Treatment) in accordance with the mass of the object we are treating. By reducing the temperature of an object to around -300ºF, we seek to manipulate and rearrange its molecular structure without damaging the item. By rearranging the molecular structure of an object, and realigning the molecules so that they become more uniform and evenly spread out, we then change various properties associated with the object, such as its wear resistance.
Perhaps the easiest way to understand what actually happens during the process is to picture a group of people walking around a shopping mall. We take these individuals (the molecules) and cram them into one huddled mass in the parking lot (the freezing process) and hold them there for multiple hours. We then tell this group to take one step out, one at a time, (the thawing process) so that they become equidistant from one another. Depending on the product, we may also add various stages of heat treatment using ovens that we maintain in-house to conquer various other stress factors which we seek to eliminate.
Deep Cryogenic Tempering allows for a significant increase in abrasive wear resistance and durability for many metal-based objects. There are also a few other materials which benefit from the process and we’re always experimenting with companies around the globe to see if we can help improve all sorts of products. The increases we’ve seen in tensile strength, toughness and stability may couple with the release of internal residual stresses for different components, and some metals respond better than others. The typical end results observed by our clients include increased product life, increased durability, reduced breakage, easier cleaning abilities, and some very specific enhancements that are dependent entirely upon the project. Many changes are dependent upon the type of steel or metal used in a product, in addition to how a product was formed or created.

Cryogenic Control Systems, Inc. (Cryo-con) is a manufacturer of electronic equipment for both laboratory and industrial process control applications. Our mission is to provide the cryogenic industry with high quality, innovative, and technologically superior instrumentation
Cryo-con’s core technical strength is the development and manufacture of cryogenic instrumentation. This often requires the design of unusual circuits that work with the exotic sensors found in some cryogenic systems. However, much more importantly, our products must be made to operate in extremely low noise environments without corrupting any measure of overall system performance.
Cryogenic techniques are frequently used to lower electrical noise in environments where extreme sensitivity is required. If system instrumentation couples electrical noise into such an environment, even at an extremely low level, measurement data can easily be corrupted or destroyed. Electronics designed primarily for room-temperature applications are frequently unsuitable for cryogenic use.
Every Cryo-con product is designed for extremely low noise cryogenic environments. Therefore, the minimization and management of electrical noise is a key element of our design methodology. This requires extensive experience in the use of modern components that must be applied with tested and proven noise reduction techniques.
Cryo-con’s development staff has worked together as a team for over 15 years. Our experience with dilution refrigerators and many-channel SQUID systems is leveraged into our products; which we believe are the lowest noise instruments on the market today.
Digital Signal Processing (DSP) is used to significantly improve performance in a wide range of applications. In Cryo-con’s products, DSP is used to improve measurement accuracy and control stability well beyond limits imposed by electronic hardware. Examples include the signal decimation, lock-in detection and Cubic Spline algorithms used in temperature measurement as well as the signal dithering and enhanced PID used in our control loops

The customer’s object is cooled by mounting it to a cold finger through which circulating, constant-pressure cold helium flows to absorb the heat load. The cold helium is cryocooled by a Gifford-McMahon Cycle Cryocooler separated from the cold finger by the flexible Cold Helium Transfer Line, eliminating the vibrations. The complete system is closed-cycle and operates with the reliability of the GM Cryocoolers and with a warranty of 10,000 hours. The CHCS comes in two capacity sizes: 120W and 200W @ 80K, the CHCS120 and CHCS200.
