Why a Separator Extends the Life of Your Boiler and Pump

The two most common causes of premature equipment failure are ferromagnetic sludge (magnetite, rust particles) and dissolved gases in the heat-transfer fluid. Both are eliminated by a [separator](/catalog/separatory). **How a magnetic sludge separator works** Inside the housing, the flow velocity drops sharply — heavy particles settle into the lower sludge chamber, while a powerful magnet captures ferromagnetic inclusions. At the same time, a cartridge collects micro-bubbles of air and vents them through an automatic air vent at the top. In the Termojet range, TJT6G/TJT7G handle dirt, TJV6G handles air, and the combined TJVT6G does both. **What this means in practice** - Reduced abrasive wear on [pump](/catalog/nasosy) impellers. - Elimination of cavitation and the characteristic «gurgling» noise. - Lower pump energy consumption. - Slower corrosion of the boiler heat exchanger. **Particularly important for heat pumps** Systems with a [heat pump](https://tjheatpump.com.ua/) have plate heat exchangers that are sensitive to contamination. The TJ7575 magnetic separator protects them and keeps the pump running efficiently for years. **Maintenance** Draining sludge from the lower chamber twice per season — at the start and midpoint of the heating period — is recommended. The procedure takes a minute and does not require shutting down the system. For boiler rooms above 50 kW, the separator pays for itself within one or two seasons.
