Cryogenic Institute of New England

Who We Are

Cryogenic Institute of New England is a research and development center within NitroFreeze. The purpose of the Institute is to provide data and analysis for advancing the proprietary processes and formulas used by NitroFreeze.

The Institute was formed during the technology transfer of NitroFreeze founder, Mr. Salews, to our present owner and CEO. The Institute has evolved to include a comprehensive, renewable, multi-year Technology Assistance Agreement with a leading firm in the Cryogenic Tempering industry. This agreement includes support, consultative services, access to databases and applications history. The controls developed by NitroFreeze are modified extensions of the best commercial heat/cool controller circuitry available and accompanying computers.

Cryogenic Institute of New England is a member of the Center for Heat Treating Excellence and works in conjunction with members of the Advanced Casting Research Center. CINE is proud to join over 100 corporate partners that represent the leading corporations of the metal processing industry focusing on near and net shape manufacturing.

Why We’re Unique

With the attachment of up to five temperature sensors (thermocouples) at selected critical locations on the part(s) being cryogenetically tempered, and monitoring them individually, cooling and heating ramps can be controlled to within 0.5% in a 670°F window, i.e, -320°F to +320°F. Consequently the slopes of the ramps may vary during processing as they are temperature sensitive and not a static fixed formula. Even at the start, ambient temperatures are factored into the process. This type of process consideration is critical where there are large geometrical changes in the shape of the part. Visual monitors are constantly inspected by our operators for any deviation from the set programming and audible alarms are activated.

Before processing, each item is evaluated carefully, and an appropriate process recipe is determined based on its size, alloy, weight and geometric size. Differences in each of these criteria impact the controlled cryogenic process program that is used.

We maintain hundreds of process programs on disk for a myriad of alloys and shapes from tooling to forges to motor sports and consumer items. For certain repeat items received from a customer, single program disks may be maintained for their specific applications. Excellence in all phases of our performance is paramount.

How We Came To Be

Cryogenic Institute of New England, Inc. (CINE) was formed after the acquisition of Nitro-Freeze, LLC., a Connecticut based company. It was moved to its current location in Worcester, Massachusetts in early 2002. The previous owner, Richard Salews, established an investment casting company over 35 years ago and became involved in Cryogenic Tempering as part of the business. He remains active today with CINE as an advisor.

Mr. Salews was keenly aware that abrasion, stress and corrosion control were critical to his business as control of these elements defined the quality of the casting that he could provide to his customers. Complex custom tooling that was often required for after-machining was not only expensive, but when sharpened, would change dimensions and often have to be discarded.

Perseverance in overcoming these obstacles led to better temperature controls, alloy knowledge and the means for their control. Cryogenics, in its infancy, appeared to contribute to pronounced improvements in all these directions.

With the advent of sophisticated computers, he advanced a portion of his operations into molecular science of cryogenically tempering metals and other materials. This knowledge coupled with years of practical experience was transfered to the Cryogenic Institute of New England, Inc. by Mr. Salews when he sold his business. He remains committed to the advancement of technology and supports CINE in various technical capacities on an as needed basis.

In 2002 we added our cryogenic deburring and deflashing services for the removal of burrs and flash from machined and molded parts. Today, it is one of the mainstay services of our business.

Our newest offerings include cryogenic helium processing and thermal cycling. These processes are ideal for materials testing, failure analysis and deep cryogenic tempering. Typical applications these services usually come from are the aerospace and weapons industries.
