Introduction
DHD was engaged to replace an aging Hamon timber field-erected cooling tower.
During a prior inspection, DHD found that the internal timber structure had deteriorated significantly, rendering the cooling tower unsafe for continued operation.
The Challenge
The existing cooling tower had to be dismantled in a restricted space where crane access was limited.
The fan machinery had to be removed first, using a telehandler.
The large steel sump had to be cut into smaller sections for safe removal.
Beneath the sump, a series of brick piers also needed to be removed before reconstruction could begin.
The Solution
To overcome these challenges, DHD implemented a modular, stainless-steel framed, GRP-cased cooling tower that could be built in small sections on-site. The structured approach included:
New Support Structure: A robust steel support frame was installed to accommodate the new cooling tower.
Modular Assembly: The cooling tower was constructed in phases, from framework to cladding, internal components, water distribution, and fan machinery.
Enhanced Maintenance Access: A dedicated access platform was incorporated to facilitate future maintenance without requiring scaffolding.
Seamless Integration: DHD also managed the installation of pipework connections from the old system to the new cooling tower.
The Benefits
DHD delivered a full turnkey solution, ensuring:
Safe & Efficient Dismantling: Removal and disposal of the old cooling tower, steel tank, and brick piers were executed smoothly.
Minimal Operational Disruption: Careful planning and execution allowed for safe project completion with minimal impact on production.
Long-Term Reliability: The new cooling tower was designed for durability and easy maintenance, ensuring long-term operational efficiency.
Comprehensive Project Support: From initial consultation to final commissioning, DHD provided expert guidance, ensuring the client’s project goals were met successfully.
This case study highlights DHD’s capability in delivering tailored cooling tower solutions, even in complex and space-constrained environments.
