AHU Refurbishment

The existing air handling unit (AHU) required refurbishment to enhance operational efficiency and adapt to new air volume requirements. The project aimed to replace internal components of the AHU with newly selected ones designed for reduced air volume operation, ensuring improved performance and energy efficiency.

Project Overview

The old heating coil was removed to be substituted with a more efficient model, ensuring optimal heating performance in line with the new specifications.

What We Did

Before Refurbishment

Frost Coil & Cooling Coil

The existing frost coil, which had become inefficient and outdated, was carefully removed and replaced with a new, high-performance unit. The existing cooling coil was replaced with a new coil designed to handle the revised air volume requirements more effectively.

EC Fan Upgrade

Fan Assembly & Inverter

The belt-driven fan assembly, which was outdated and less efficient, was removed and replaced with a new fan assembly designed for better performance at reduced air volumes. The old inverter was replaced with a modern unit that supports the new system configuration.

New Filters Installed

Filters & Filter Frames

Both panel and bag-type filters were removed and replaced with new filters designed for improved air quality and system efficiency. The frames holding the old filters were also removed as they no longer supported the new filter configurations. New ones were added.

The Project Outcome

The refurbishment resulted in a significantly upgraded AHU, tailored to operate efficiently at the reduced air volume specified. The new components not only improved system performance but also enhanced energy efficiency, leading to reduced operational costs and improved indoor air quality. The project demonstrated BVS engineers' capability in managing complex AHU refurbishments, ensuring a seamless transition to upgraded technology while maintaining site safety and compliance with disposal regulations.
