Sometimes there is a need for drainage where there is no suitable drain connection in the vicinity, or there is no possibility to connect a necessary oil separator. Then a so-called evaporation channel can be a good idea in areas without special hygiene requirements such as garages, car parks or workshop premises. Evaporation channels are suitable when the flow is low and sporadic such as for example meltwater from snow in garages or workshop premises. Purus channel evaporation is made of acid-resistant stainless steel (quality EN 1.4404), but is also available in stainless steel (EN 1.4301). It has an even bottom depth for optimal evaporation and is manufactured in high quality for long durability.
