Self-cleaning gas/water heat exchanger

The X-Tube Boxer is an intelligent improvement of a tube-in-tube heat exchanger (S&T) with a cleaning system for which a patent is pending.

The self-cleaning X-Tube Boxer was developed for heat recovery from processes whose exhaust air contains high humidity, contamination or chemical pollutants.

The heat of condensation from the exhaust air is transferred to a liquid heat carrier, e.g., water.

Contaminations, deposits or fouling normally occur where the temperature in the tubes is lowest, which impairs heat transfer in the course of time.

The X-Tube Boxer is equipped with a cleaning system which mechanically cleans the outside of the inner heat exchange tubes.

A perforated plate, powered by an electric motor with spindle, travels, like a scraper, along the full length of the inner tubes and removes all contaminating material from the tubes.

Depending on the degree of contamination, the deposits can be removed from the shell space of the heat exchanger regularly for disposal.
