We have broad experience working on refrigeration.
Our engineering services group can work on any stage of chiller refrigerant conversion, from determining the effects of a ‘drop-in’ refrigerant change on capacity, to redesigning compressors for new refrigerants, to analyzing chiller system Balance of Plant impact.
In addition, Concepts NREC’s Agile Engineering Design System® software can help OEM’s in-house designers more quickly and accurately (higher performance, better COP) convert to the latest generation of refrigerants.
We also manufactures and sells specialized turbomachinery products that serve well-defined niche applications. The DeepChill™ Air Cycle Refrigeration System using air as the refrigerant in place of CFCs or other harmful coolants offers better efficiency than more traditional refrigeration cycles such as Cascade-, LN2-, and Ammonia-based systems, making air cycle refrigeration well suited and safe for food processing.

Concepts NREC designs, manufactures and tests turbochargers and turbocharger components for diesel and gasoline engines as well as compressor and turbine stages for gas turbine engines. We can also provide auxiliary system components for engines including fuel, oil and water pumps.
Concepts NREC has extensive experience in the field of waste heat recovery, including providing ORC turbines for exhaust heat recovery from diesel and gas turbine engines.
We cover the full range of transportation industries, including passenger cars, trucks, F1 racing, off-road vehicles, marine craft of all sizes, and aircraft piston, turbojet and turbofan engines.
In addition to contract manufacturing complete turbomachinery products for customers, Concepts NREC manufactures and sells specialized turbomachinery products that serve well-defined niche applications.
These products are jointly developed with customers who first establish a market need for a new or improved technology. Concepts NREC then supplies the development expertise to turn their specification into a successful product. However, rather than just providing services for a fee, development costs are shared, enabling Concepts NREC to establish additional applications and markets for the product and generate noncompetitive sales. The results allow development costs to be amortized over larger production quantities, and both companies further benefit by producing a better product at a lower cost.
APS is Concepts NREC’s software maintenance and support program that elevates us from just a software provider to a valued partner.
An APS subscription is included with all annual licenses and is a highly-recommended option for perpetual software licenses. Every software customer is supported for one month following purchase for any installation questions that may arise. Learn more on the Agile Products Support Membership Benefits Datasheet.

The design basics presented in this textbook provide the analyst with a single source that is necessary to determine if a radial or axial turbine should be used to meet the design point conditions of the sCO2 system.

The parallel operation of two compressors used in a typical Recompression sCO2 cycle will require the mastery of the techniques described in this textbook to avoid surge and stall in compressors as well as to control the splitting of the flow between the two compressors.
