Researchers must look beyond nonflammable chemicals
April 3, 2017
NIST’s study, entitled “Limited options for low-global warming potential [GWP] refrigerants,” focused on residential and small-commercial single-package and split air conditioning systems, but the authors said their conclusions also generally apply to room air conditioning units and other refrigeration and heat-pump systems currently using common, ozone-depleting refrigerants such as R-410A or R-22, which are still used in some developing countries today. “The takeaway is there is no perfect, easy replacement for current refrigerants,” NIST chemical engineer Mark McLinden said.
The U.S. Environmental Protection Agency (EPA) has not given any indication that it will target R-410A in residential applications, and under the Trump administration, the agency may perhaps be less aggressive than it was under the Obama administration and, therefore, less likely to push for additional refrigerant phasedowns.
Extreme Ultra is a solution designed to repair refrigerant gas leaks by guaranteeing a complete, permanent, and elastic endurance of the system. It’s a mix of components, which are gas- and lubricant-friendly.
OEMs, consultants, contractors, and end users respond

Danfoss, a manufacturer of high-efficiency electronic and mechanical components and controls for air-conditioning, heating, refrigeration, industrial, and water systems, recently conducted an online survey to gauge industry acceptance of CO2 refrigeration systems in North America.
Company’s position includes approvals for HC and HFO refrigerants
March 1, 2017
In follow-up to the document that Tecumseh issued in January 2016 regarding recommended refrigerants, the company says it is making the required changes to its compressors and condensing units in order to meet the performance, reliability and safety requirements for use with alternatives to R-404A and R-134a refrigerants.
Of course, reclaimers can only reclaim what contractors and technicians recover, and while the R-22 numbers may never match the hoped-for projections, the industry is already looking to the future and preparing to address new challenges in a post-hydrochlorofluorocarbon (HCFC) world that also is likely facing a phasedown of hydrofluorocarbons (HFCs).
The Green Tech Line of refrigeration and air conditioning components is designed for use with natural refrigerants R-290 (propane), R-600a (isobutane), and R-744 (CO2). These high-quality, hydrocarbon (HC) and CO2-ready system components include valves, controllers, transducers, filter driers, and microchannel heat exchangers.
The new facility will triple the company’s capacity
February 15, 2017
The Chemours Co., a global chemistry company in titanium technologies, fluoroproducts, and chemical solutions, announced that it has broken ground on a new HFO-1234yf production facility. The new facility, located at the Chemours Corpus Christi plant in Ingleside, Texas, will triple the company’s capacity for its HFO-1234yf-based-products, which are low-global warming potential (GWP) and better for the environment.
