These services are geared towards extending the longevity of your equipment, ensuring that it works effectively and efficiently over the long term, and incurs fewer operational expenses, all through services that come at less of a cost to you.

Common Reasons For Heat Exchanger Failures

Through a comprehensive failure analysis, our dedicated technicians can identify exact reasons for failure in equipment, which generally details one of the following common reasons for failure.

MECHANICAL DAMAGE FROM ICE FORMATION IN REFRIGERATION HEAT EXCHANGERS
  • Electrical interlock on pump failures or trips.
  • Flow switch in water pipeline.
  • Differential pressure switch on water in/out on heat exchanger.
  • Manual reset anti-freeze stat mounted correctly on heat exchanger.
  • Low suction protection on refrigeration circuit.

MECHANICAL DAMAGE FROM BAFFLE PLATE WEAR OR FOREIGN OBJECTS IN HEAT EXCHANGER

Excessive flow in the heat exchanger may lead to baffle plate wear, causing it to vibrate through the tubes of the heat exchanger.

CHEMICAL / BACTERIOLOGICAL ATTACK ON COPPER TUBES

Without proper water treatment water systems are prone to growth of sulphate reducing bacteria. This bacterium propagates under a self-built barnacle and turns anaerobic, then starts generating sulfuric acid that can chew through any metal.


Sulphate reducing bacteria attack as seen when barnacle is removed and damaged area is cleaned up.


The holes in a tube seen from the inside.


In this case inferior quality copper tubing was used for manufacture and this led to electrolytic corrosion.

DIRT IN THE SYSTEMS

Frequent failures and below-design performance of chill and hot water systems is a real problem due to dirt in the system. A common result of failure is that the maintenance staff removes strainers “because they block too easily”.

FAILED HEAT EXCHANGERS

We offer comprehensive testing, inspection, repairs, and replacements for failed heat exchangers and compressor motors to restore the functionality of refrigeration equipment to optimal condition.

These services offer a comprehensive analysis of failed heat exchangers so that the right solution can be sourced, either through the provision of new units, or repairs that see to the source of the damage.
