TEKO was founded in 1982 as a distributor. Over time, we adopted products into our range from various manufacturers for whom we were distributing. Alongside semi- and fully hermetic compressors (FRASCOLD and Embraco), heat exchangers of the WHITELINE series and controllers from WURM, we offer valves and accessories from GMC and Castel, as well as the oilstar® oil regulation system. That means from us you receive a coordinated package for your optimum refrigeration system – from one source.

This family-run company was founded in 1961 and is now a leading supplier of refrigeration and air-conditioning components. With their high quality and production standards, Castel was one of the first Italian suppliers to become ISO 9001 certified in 1990. Since the very beginning, the company has been working intensively on research and development of existing technologies – as well as future-oriented products produced exclusively in their proprietary factories in Italy.


GMC products have been used in the TEKO series (rack units /single-compressor units) since 2007 and have already proven their worth time after time. This young, dynamic company was founded in 2002, since when it has been a successful manufacturer of refrigeration and air-conditioning components. GMC quickly established itself on the market and offers high-quality valves, filters and connections for all kinds of needs.

The range at TEKO.

You can obtain a large number of GMC and Castel products from us, either separately or in attractive packages.


To ensure your refrigeration systems keep running for a long time, a good supply of oil is important. That is why we have worked intensively on developing oil components and have accompanied the series oilstar®. This is being continually enhanced and optimised. We have used oilstar products throughout our entire product range since 1999. Be it silencers, oil separators and suction line accumulators, oil regulation systems or filter dryers – you can obtain the entire range through us, even individually. The products stand out for their high quality. The components are subject to 100% pressure and tightness tests in comprehensive quality assurance measures.
