University Laboratories Measure Performance of Low-GWP Refrigerants Inside of MicroGroove Tubes, Says Copper Alliance

Prediction accuracy of simulations depends upon the accuracy of laboratory experiments

MicroGroove Excels in Process Cooling Application

New York, New York (June 8, 2016) – The International Copper Association announced that MicroGroove copper tubes are now being used in the condenser coils of turnkey refrigeration systems from PRO Refrigeration.

The refrigeration systems are used to cool wort, control fermentation and chill conditioning tanks. Smaller-diameter copper tubes offer improved performance in a smaller footprint compared to larger-diameter copper tubes or aluminum microchannel tubes.

Smaller-Diameter Copper Tubes are the Key to Efficient Use of Propane in ACR Products

New York, New York (June 6, 2016) – Also known as R-290, propane (C3H8) is a flammable hydrocarbon with an ultralow global warming potential (GWP) index of only 3.3, that is, many hundreds or thousands of times lower than conventional refrigerants.

MicroGroove Is Suitable for Coil Size from Small to Very Large

New York, New York (8 April 2016) – MicroGroove technology is expanding into all sizes of heat exchanger coils from small to very large. Not many years ago there were just a handful of MicroGroove applications but that’s no longer the case. MicroGroove smaller-diameter copper tubes can be found in a myriad of products, with tube lengths ranging from a few inches to several meters; and capacities ranging from hundreds of watts to hundreds of kilowatts.

MicroGroove Advances and Applications Highlighted at ACREX 2016

Mumbai, India (25 February 2016) – The International Copper Association announced today that the latest advances in MicroGroove, including new manufacturing techniques, new design tools and new applications, will be highlighted at ACREX 2016 at Booth E-25.

Orlando, Florida (22 January 2016) – As industry phases out high-GWP refrigerants and strives for energy efficiency, MicroGroove smaller-diameter copper tubes are now more relevant than ever. The march toward smaller diameter tubes began more than a decade ago and now tube diameters of 5 mm or smaller are commonplace in round tube, plate fin (RTPF) evaporators and condensers. MicroGroove copper tubes are the new benchmark for coils in residential and commercial ACR products.
