Air Exchanger

Air exchangers play a vital role in the performance of furnaces and also contribute significantly to the maintenance of optimal temperatures within rooms. However, there are certain instances when their smooth operation is hampered, leading to damages, which might necessitate the need for air exchange repair services. It is good to know some of these problems that might impact the efficiency of the units, so that you know exactly what to do when trouble occurs.

Fouling

Fouling happens when solids such as dirt, sand or scale are deposited on the conducting surfaces such that they stop the unit’s ability to transfer heat effectively. If not taken care of quickly, the solids may end up blocking the internal tubes, leading to more problems. Routine maintenance should be sufficient to prevent fouling from happening. Otherwise, a breakdown will be imminent and so do the call for air exchanger repair services.

Leakages

An air exchanger may experience either internal leakage or external leakage or both. Leakages occur when the gaskets are full, and there is no release for the excess pressure, making it build up and forcefully find its way out. Other than pressure build up, leakages may also be caused by weld defects, metal fatigue and corrosion.

Formation of air pockets

The formation of air pockets within the unit is another problem that will impact negatively on the efficiency of the air exchanger. Air can enter the exchanger via various places, and sometimes unwanted gas accumulates in the tubes due to improper sealing. Air pockets will cause an imbalance in the distribution of heat, thus making the unit operate less efficiently. This problem can be avoided by strictly following the manufacturer’s guide for optimal performance.
