Compressor-Type Radiator Flushing Machine

How does a compressor-type radiator flushing machine work?

Compressor-type radiator flushing machines deliver pressurized air pulses into the system water at set intervals. The turbulence created by the air-water mixture mechanically dislodges sludge and deposits adhering to the inner surfaces of pipes and radiators. The loosened debris is carried by the water flow into the machine's tank or to the drain. In bidirectional models, the flow direction can be reversed to enhance the cleaning effect.

Where is it effective?

• Underfloor heating circuits: Removing sludge accumulated in long, narrow pipe coils.
• Older radiator systems: Adding a mechanical effect to chemical cleaning in radiators with heavy sludge deposits.
• Combi boiler and heat exchanger lines: Clearing sludge that restricts flow.
• Where chemical use is to be minimized: The mechanical action allows results to be achieved with less chemical.

The compressor-type model in this category features a 9-liter tank and bidirectional operation, providing a portable solution.

Application recommendations

Before starting the cleaning process, the combi boiler must be isolated from the system or protected as recommended by the manufacturer. Cleaning each circuit individually at the underfloor heating manifold gives more noticeable results. The intensity of the air pulses must be set appropriately for the age of the system and the pipe material; exercise caution with very old or weakened systems. After cleaning, the circuit must be thoroughly flushed with clean water, bled, and a corrosion inhibitor added.

Maintenance

The machine's air filter and hose connections should be checked after each use. Dirty water remaining in the tank and hoses must be drained and rinsed with clean water. If the machine will not be used for an extended period, store it in a dry place protected from frost.

Frequently asked questions

Does compressor-type cleaning require chemicals?

The mechanical action can produce results on its own; however, combined use with a suitable chemical is more effective in cases of heavy scale buildup.

Does it damage plastic pipes?

It can be used on underfloor heating pipes at the appropriate pressure setting; the pressure should be adjusted according to the condition of the system.

How is it different from a conventional machine?

Conventional machines only circulate the solution; compressor-type models add a mechanical effect through air pulses.

How long does it take to clean an underfloor heating circuit?

The time varies depending on the length of the circuit and the level of contamination.

Is additional equipment required?

Connection hoses and suitable adapters are needed; you can browse the spare parts category.

Is a compressor-type machine noisy during operation?

An intermittent sound in the pipework during air pulses is normal; this noise indicates that deposits are being dislodged.
