Record was founded in 1946 in Bonate Sotto, Italy, as a manufacturer of air valves for tires. The company philosophy has always been to produce and assemble all the key components internally, to be able to have the whole process under control and assure no leakage in the final product. Record’s in-house technology starts from the manufacturing of metal parts up to their automated assembling and testing. The know-how matured in the tire application was easily transferred to many different applications where preventing leakage of air or gases is crucial, among these the products for refrigeration systems are the ones which, in the past decade, experienced the most evolution. The introduction of new gases and natural refrigerants, in fact, has presented different challenges compared to air and other traditional fluids in terms of temperatures and pressures. Thanks to internal production and the constant communication with customers Record has been able to move quickly and design and develop new products that can respond to the new demands from the market. In 2006 Record patented its first valve core for a thermo hydraulic systems, particularly using CO₂ gas in high pressures, and in 2014 it filed and deposited patents for valve cores to be used in R290 and R744 systems for residential and industrial markets. These products are the first ones launched on the market designed specifically for usage with natural refrigerants, and their market share has been in constant growth in the past decade.

The Temprite tradition of innovation continues with energy-efficient coalescent and conventional oil separators for every type of refrigerant. The Temprite 130 Series of coalescent oil separators is designed specifically for transcritical CO₂ systems. Temprite products are engineered and manufactured to enable improved refrigeration system thermal efficiency by minimizing oil and dirt in the system’s evaporator. This results in shorter compressor run times, reducing carbon emissions and energy consumption and providing the highest possible return on investment. Temprite products are the solution to rising energy costs, longer system life and reduced carbon emissions. Company History Founded in 1924, Temprite was a pioneer in the refrigeration industry and one of the first companies to specialise in refrigeration components in the U.S.. Early Temprite products included beer coolers and dispensing valves for soda fountains and water coolers. The Temprite reputation for innovation arose when the company originated some of the earliest refrigeration components including the conventional oil separator in its current configuration: Every conventional oil separator is a copy of a Temprite oil separator. In 1988, Temprite was the first company to design and manufacture coalescent oil separators and oil reservoirs with the introduction of the high-efficiency 900 Series. The 920 & 920R Series were developed in 1990-1991 to meet customer needs for energy savings, lower carbon emissions and increased system life. Today, Temprite is a premier brand name in the industry. Building on decades of experience in manufacturing components for the refrigeration industry, the Temprite tradition of innovation continues with energy-efficient coalescent and conventional oil separators for every type of refrigerant, including naturals. 2015 marks the launch of hydrocarbons refrigerant-based components. International Distribution The Temprite plant is located in West Chicago, Illinois, USA, with sales and distribution facilities in Tokyo, Japan; Rotterdam, The Netherlands; Stuttgart, Germany; Ankara, Turkey; Bangalore, India; and Sydney, Australia.
