SD – SDR – SDS Dirt Separators

The SD dirt separator series has been developed to guarantee perfect system cleaning. The cartridge filtration mechanism ensures not only high-level cleaning and simple maintenance, but also traps the majority of impurities posing a risk to boilers, thermostatic valves, heat exchangers, pumps and various other equipment installed in the systems.

The high quality of the SD dirt separator, madeentirely in AISI 304 stainless steel,guarantees improved resistance against corrosion and therefore higher quality cleaning over time. STB dirt separators are insulated using 20 mm closed-cell chemically cross-linked polyolefin resin, finished with 0.6 mm AISI 304 stainless steel, to ensure the least possible energy dispersion and guarantee sturdiness using anti-corrosive and durable materials. Our range includes a selection of standard models, from the smallest with DN25 connectors up to the largest with a DN 300 connector.

The range of “M” dirt separators also features a neodymium magnetic drain plug for improved water filtration, trapping even the smallest ferrous residue in systems. Thanks to its stainless steel finish, it boasts high resistance against corrosion and is extremely easy to clean during normal maintenance. STB Divisione Winter dirt separators work with a load loss of less than 1 mH2O.
Therefore, maintenance should be performed as soon as this value is exceeded. For special systems or in cases of complex installation layouts, thanks to our flexible production it is possible to produce made-to-measure filters with connectors positioned according to specific needs, thus optimising all types of installations.

SD, SD-R and SD-S dirt separators by STB Divisione Winter are manufactured and sold in compliance with Directive 97/23/EC.
