AHU Refurbishment &
Pipework Replacement
Located within the Newton Mearns Shopping Centre, BVS focused on the comprehensive refurbishment of three existing weatherproof Air Handling Units (AHUs) that provide tempered air to the main shopping mall areas. The client required a cost-effective, energy-efficient refurbishment that would extend the operational life of the AHUs while improving performance reliability. BVS was commissioned to undertake a full refurbishment designed to modernise and futureproof the plant without the disruption or high cost of complete replacement.
Project Overview
By retaining the existing AHU housings and structure, BVS delivered an environmentally responsible solution that reduced waste and embodied carbon while ensuring improved energy efficiency, reduced maintenance demands, and a projected service life extension of 10-15 years. The works were carefully coordinated to minimise disruption to daily shopping centre operations, maintaining safe and continuous occupancy throughout the refurbishment process.
What We Did
Belt-Driven Fan & EC Fan Replacement
Existing belt-driven fans were replaced with modern equivalent units to enhance reliability and maintain system performance. On one AHU, the belt-driven fan was replaced with a high-efficiency EC fan to improve performance and reduce energy consumption.
Gas Burner Replacement & Controls Integration
Existing gas burners were removed and replaced with fully modulating models compliant with current gas safety standards, integrated into the existing Trend control system. Commissioning verified full modulation, speed control, and operational synchronisation.
Panel & Bag Filter Upgrades
Panel and bag filters were upgraded to AF101 Type AP and AB85 Type respectively, improving air quality, filtration efficiency, and overall system performance across all three units.
Gas Distribution Pipework Replacement
The existing mild-steel gas distribution network was replaced with new 316-grade stainless-steel pipework with pressed joints, isolation valves, and Big Foot support systems. A bridge scaffold was manufactured and craned over the shopping centre's glass structure outside of normal working hours, coordinated with the crane team to ensure safety.
