Introduction
DHD was engaged to replace the bearings on two Evapco Closed Circuit Cooling Towers at a consumer goods manufacturing plant.
Over time, the bearings had become increasingly noisy due to wear and age, leading to complaints from nearby residential areas. To address this, DHD executed a structured replacement plan to minimize disruption while restoring optimal cooling tower operation.
The Challenge
Strict Time Constraints: All work had to be completed over two weekends to avoid interference with the plant’s production schedule.
Corrosion & Component Wear: Due to the age of the cooling towers, corrosion on the fan shafts made bearing removal challenging.
Logistics & Equipment: Ensuring all necessary tools and personnel were on-site to manage potential difficulties with disassembly.
Tower One required a complete bearing replacement along with a new taper-lock bush and pulley, while Tower Two required new bearings to be installed.
The Solution
DHD implemented the following measures to ensure a successful outcome:
New Bearing Blocks Installed: Replaced bearings at both ends of the fan shafts for improved performance and longevity.
Component Upgrades: Tower One received a new taper-lock bush and pulley for enhanced durability.
Efficient Execution: All works were completed within the designated weekends, minimizing operational downtime for the client.
The Benefits
By leveraging DHD’s extensive supplier relationships and technical expertise, the project delivered:
High-Quality OEM Components: Ensuring long-term reliability and performance.
On-Time Project Completion: Adhering to the client’s strict weekend schedule.
Minimized Disruptions: Work was executed efficiently, addressing noise concerns and restoring optimal functionality.
Seamless Coordination: In collaboration with service partner SPX Cooling, all materials were delivered on time, ensuring smooth execution.
This innovative cooling solution ensured a smooth transition to commercial operation, demonstrating DHD’s expertise in delivering reliable and efficient cooling systems for aluminium casthouse applications.
