At Coolclean, we understand that keeping the highest standards of hygiene in food production environments is essential. Our specialized Cooling Equipment Hygiene Services, particularly Air Handling Unit (AHU) cleaning, are designed to keep your facilities safe, compliant, and running efficiently.
Comprehensive AHU Cleaning & Treatment
Recently, our team carried out a thorough cleaning and treatment of an AHU at a prominent food manufacturing site. The process involved carefully removing old, contaminated filters and replacing them with new, high-efficiency filters to ensure optimal air quality. During the cleaning, we identified and addressed significant mould build-up within the fan section, which we meticulously cleaned off to prevent any potential contamination.

Addressing Corrosion & Duct Contamination
We observed that the fan guard and supports were showing signs of corrosion, which, if left unchecked, could compromise the structural integrity of the unit. Our team treated these components to prevent further deterioration. The supply air and return air ducts—integral pathways for keeping proper airflow—were found to be dirty. Notably, the return air duct, which channels air back into the factory, was filled with mould spores, posing a serious risk to food safety. Unfortunately, due to limited access, cleaning the interior of these ducts was not possible during our first service.

Improvement Notice & Recommended Actions
An improvement notice was issued highlighting the following issues:
Issue: Both supply and return air ducts are dirty, with the return duct potentially full of mould. No access points are available inside the ducts for effective cleaning.
Effect: This presents a potential risk of contaminating food products and compromising hygiene standards.
Action: To mitigate these risks, we recommend installing access hatches into both the supply and return ducts. These hatches will enable routine cleaning and inspection, ensuring the ducts remain free of mould and debris.
