Case Study – AHU Evaporator Fabrication & Renewal Scope

Evaporator leakage and cannot be identified?

Cooling deficiency?

After running through an inspection and following our 5 Steps Formulation, the AHU’s evaporator coil was showing signs of fatigue. There are also internal leakages which could not be seen from outside were also identified.

Solution proposed was to install a new coil which was customized fabrication according to the ship requirements. Most importantly, The installation process was completed within 24 hours.

Case Study – Maintenance Program for SMC106S, CMO28/26 Compressors


Are you experiencing unknown low cooling efficiency?

Similar to the previous case study on HVAC issues and how resolved the issue of low cooling efficiency.

As per our 5 steps flow set up, we first have identified the problem, shared our findings and solution: Overhauling of the main AC as well as HVAC maintenance program for SMC106s, CMO28 & 26 Compressors were proposed. After close inspection, our engineers’ troubleshooting solution was also to overhaul the main AC while multiple spare parts were required for replacement.

Case Study – Low AHU Performance & AHU Renewal Work


Are you experiencing Low AHU system running on low cooling efficiency?

This is a case study of how we identified the vessel’s HVAC issues and resolved the issue of low cooling efficiency. The vessel was anchored at Tuas Megayard, Singapore for the service rendering.

As per our 5 steps flow set up, we first identified the problem; the old unit reached an advanced stage of corrosion, especially the coils and the blower. Contaminants were also found in the system. The solution is to install and replace the ship’s AHU as the old unit is malfunctioning due to wear and tear.
