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.
