Finning CAT - Dry Cooler Cleaning

In 2022, Finning CAT approached us with a unique challenge: cleaning the cooler units on their aloft containers housing V20 gas engines. These engines play a crucial role in generating electricity to support the National Grid during peak demand.

We eagerly accepted the challenge and conducted initial test cleans that proved successful. Following this, we underwent Finning’s rigorous approved contractor accreditation process and proudly gained approved status in August 2022.

Proven Results and Nationwide Contract

Soon after accreditation, we were called to a site where an alarm indicated a cooler was overheating. Using our specialised cleaning process, we restored the unit’s efficiency, resulting in the cooler running 10 degrees cooler after re-commissioning—a significant improvement that enhanced performance and reliability.

From April to June 2023, we were commissioned to clean 135 Finning CAT units across the country, from Durham all the way down to Gravesend. The contract was a great success, and we were honoured to be invited back for the annual cleaning programme scheduled from April to July 2024, including four units on the Isle of Wight.

Our Approach

Cleaning these cooler units isn’t as simple as a quick spray. We developed a specialised cleaning process tailored to the sensitive and high-performance nature of the V20 gas engine coolers. Our team carefully removes dirt, grime, and build-up that can cause overheating and reduce efficiency—all without damaging delicate components.

We started with successful test cleans and then passed Finning’s tough approved contractor accreditation in August 2022, proving our expertise and safety standards.

Why This Matters

Cooler units that aren’t properly maintained can overheat, leading to equipment failure, costly downtime, and even safety risks. Regular, professional cleaning helps prevent these issues by improving airflow and heat dissipation.

When we were called to fix an overheating unit, our process brought the temperature down by 10 degrees after re-commissioning—showing how effective proper cleaning can be for operational reliability.
