The full 3YO Technology range: laser cutting, welding & maintenance
3YO Technology is an Italian manufacturer of liquids that cut cleaning time and cost on laser and plasma cutting systems, robotic MIG/MAG welding, and general industrial maintenance, biodegradable. The liquids are applied with the brand's own applicators: 3YO GUN (wireless) or 3YO AIR (reusable manual sprayer). Lang & Sin is an authorized 3YO Technology distributor in Romania.
About 3YO Technology
3YO Technology is a brand of EPCM.EXPERT SRL, based in Pergine Valsugana, near Verona, Italy. The company has developed natural-based protection and maintenance liquids for over 12 years, tested in more than 55 countries, with formulations verified as readily biodegradable under the OECD 301B method.
Most products in the range carry no hazard pictograms and require no Safety Data Sheet (SDS), being formulated from food-grade derived ingredients with no added hydrocarbons.
EuroBLECH Award 2024
3YO Total Shield (TS) and 3YO GUN took 2nd place in the "Trenntechnik" (cutting technology) category at the EuroBLECH Award 2024, presented in Hannover on October 22, 2024 by MM MaschinenMarkt and blechnet (Vogel Communications Group), for their laser cutting table cleaning and protection solution.
A product can appear in more than one category at once: for example 3YO SP is listed under laser cutting, plasma cutting, and welding. Click any card to see its full data sheet, right there. The manufacturer has already announced 3YO Pulse and 3YO Metal Skin, but hasn't published descriptions or specifications for them yet; we'll add them as soon as they're available.
