Sludge and Air Separators: Why Your Heating System Needs Them
Sludge and micro-air bubbles are the main enemies of any heating system. A Termojet separator tackles both problems and significantly extends the service life of the boiler and pumps.
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 — magnetic separator specifically designed for heat pump systems, where fluid cleanliness is critical for the heat exchanger.
The Benefits
- Reduced abrasive wear on pump 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.
