Cleaning A Heat Exchanger

High temperatures, conductive media and non-stop operation of the device ensure that in the course of time, every heat exchanger becomes contaminated. This contamination often results in reduced heat exchange. After a certain time, the deposits will lead to the heat exchanger no longer operating optimally, or even becoming completely clogged up.

Initially, the contamination will result in a loss of efficiency. This can be demonstrated by a reduction in the heat exchanged and also by a loss of pressure. If the contamination is not regularly removed, this can have serious adverse consequences.

TCI Cleaning is able to clean almost any heat exchanger. We carry out an accurate final check and can install new rubbers in sets of plates. Of course, every step is documented.

The Possibilities:

  • Gasket/rubbers
  • UV crack detection
  • Installation/removal
  • Pulling the tube bundle
  • Revision of the housing
  • Pressure testing

Plate Heat Exchanger

In a heat exchanger, specially developed rubbers hold the numerous plates closely together. The operation of the heat exchanger is comparable to that of a tube heat exchanger. One medium heats up the other. Here as well, there is a similar risk of contamination. The flowing medium deposits substances that can eventually clog the heat exchanger.

This contamination can be pyrolysed by heat treatment or can be broken down chemically. Various post-treatments are available to guarantee a level of cleaning that allows the original efficiency to be achieved.

After cleaning, every plate can optionally be checked for microscopic cracks using UV light. Any aged or damaged plates can be repaired or replaced. If required, new gaskets can then be installed.

Tube Heat Exchanger

This type of heat exchanger can be either thermally or chemically cleaned and is also often subjected to an ultrasonic post-treatment. This guarantees effective cleaning, allowing us to restore the original efficiency of the heat exchanger.

As tube heat exchangers are critical products, the treatment process is accurately monitored. Due to factors including mass, composition, contamination and specific requirements, the cleaning process used to treat these heat exchangers is completely manually directed.

Based on the limitations of the material, a protocol for the cleaning process is drawn up. When this is carried out thermally, we will follow a manually directed protocol. By installing thermocouples at strategically determined locations, TCI Cleaning is able to track and report on the technical specifications of a protocol. If desired, every step of the process is accurately reported and documented.
