Introduction
DHD was engaged to repack a two-cell field-erected Marley Cooling Tower at a paper mill. The existing fill pack had become extremely brittle over time, necessitating a full replacement.
Additionally, cleaning works were carried out to maintain system efficiency and prevent contamination.
The Challenge
Safety Considerations: Due to the large field-erected design of the cooling tower, stringent health and safety measures were required.
Secure Working Platform: Youngman Boards were utilised to create a safe working environment for personnel inside the cooling tower.
Fall Protection: All personnel wore fall restraint harnesses and lanyards to minimise the risk of falls.
Efficient Material Handling: New materials were transported to the cooling tower using a telehandler, while old materials were efficiently disposed of in site skips.
Coordination with Client: The project required careful logistics planning to ensure skips were loaded and replaced promptly, preventing delays.
The Solution
DHD provided:
New Polypropylene Fill Pack: Installed according to the original thermal specifications to optimise cooling performance.
Comprehensive Cleaning Services: Ensuring no contaminants remained in the process water system, preventing potential blockages in circulating pumps.
Plant Equipment: Supplied as required to facilitate project completion.
The Benefits
By collaborating with their installation service partner, Barrett Industrial Cooling, DHD ensured:
On-Site Readiness: All materials were delivered ahead of personnel mobilisation, streamlining the installation process.
Safe & Efficient Execution: The project was completed within the required timeframe while maintaining strict safety standards.
Restored System Efficiency: The refurbished cooling tower was returned to optimal performance, ensuring reliability in paper mill operations.
This successful cooling tower repack highlights DHD’s expertise in large-scale refurbishment projects, providing high-quality, efficient, and safety-conscious solutions.
