Sludge and Air Separators: Why Your Heating System Needs Them

Most problems in heating systems — from pump noise to accelerated boiler corrosion — stem from two sources: dissolved air and solid particles in the heat-transfer fluid. A separator eliminates both. **How It Works** The separator is installed on the supply or return line. Inside, the flow velocity drops sharply: heavy particles settle in the lower sludge chamber, while a magnetic insert captures ferromagnetic deposits (rust, magnetite). Simultaneously, a special cartridge collects micro-air bubbles and releases them through an automatic air vent at the top. **Termojet Product Line** - **TJV6G** — air separator. - **TJT6G / TJT7G** — sludge separators with magnet. - **TJVT6G** — combined: air + sludge in a single body. - **TJ4F** — automatic air vents. - **[TJ7575](/catalog/separatory)** — magnetic separator specifically designed for [heat pump](https://tjheatpump.com.ua/) systems, where fluid cleanliness is critical for the heat exchanger. **The Benefits** - Reduced abrasive wear on [pump](/catalog/nasosy) impellers. - No cavitation or gurgling in the system. - Lower pump energy consumption. - Slowed corrosion of the boiler heat exchanger. **Maintenance** Draining sludge from the lower chamber twice per season takes about a minute and requires no system shutdown. For boiler rooms from 50 kW upwards, the separator pays for itself within one or two seasons through extended boiler and pump service life.
