Indirect-heating boiler
With a single coil
All the water is heated right to the bottom
- Volume: 100—5000 L
- Models: 14
- Vessel: 6 bar
Oxygen diffusing through plastic pipes causes erosion, and wear products start circulating through the system. A regular strainer must be opened with a spanner, stopping the system. Here you just open the ball valve at the bottom.

Replaces many ordinary strainers.
Sludge drains through the valve — no shutdown needed.
Less wear on pumps, valves and fittings.
A simple routine people actually follow.
