Oil-free refrigeration compressor technology offers significant benefits in terms of efficiency and performance. Eliminating oil from the system can yield up to 40% improvement in part-load efficiency compared to fixed speed screw compressors. And, this performance improvement can be sustained over the life of the compressor since oil-free compressors incur no mechanical wear during operation.

Chiller & Cooling Best Practices Magazine interviewed Peter Armbruster (Director of Sales and Marketing) and Bob Smith (Director of Product Management) at Thermal Care to gain insights into best practices used to accurately evaluate and assess a plant’s cooling needs and ultimately provide the solution best matched to the application. 

The 2020 AHR Expo, the world’s largest HVACR event, was held February 3-5, at the Orange County Convention Center in Orlando, Florida. Supported by event co-sponsors, ASHRAE and AHRI, along with 31 other major industry organizations, and more than 1,900 exhibiting companies, AHR Expo is the industry’s largest global marketplace to network, share best practices and learn about innovative solutions from all over the world. With more than 200 free seminars, the education program featured new product and technology presentations, professional certifications, and education sessions focused on general industry-wide topics, engineering, industry trends, and topics tailored to attract the OEMs, engineers, contractors, facility operators, architects and other HVACR industry professionals from more than 160 countries.

The need to pay close attention to the university’s central chiller plant has always been a priority given the energy required to power the chillers, said Michael Bolien, Manager of Central Plant Operations, University of Tulsa. At TU, seven water-cooled chillers provide 7,000 tons of cooling capacity to all university facilities. “Over the past five years, TU has had a 17% increase in cooling load, based on the square footage of new buildings. Because our central chiller plant is our biggest energy user, optimizing its operations is our first line of defense,” said Bolien.
