After handling an increased volume of production in the run-up to Christmas, many food and beverage manufacturers turn their attention to some routine cleaning and maintenance early in the new year. Air handling systems, in particular, can benefit from a bit of TLC, and at HVDS, we recommend a review of requirements, followed by a thorough clean-down of your whole system by our engineers to ensure good Indoor Air Quality and audit compliance.
You can conduct the review of cleaning and maintenance requirements yourself or we will do this for you. Look at the condition of the following:
- Air filters – Do these need changing? Review the pressure drop for all filtration stages.
- Fans – How clean are these? Is there any build-up that could lead to bacterial growth?
- Heating/cooling coils – Is there dirt trapped in the coil? Is the aluminium still in good condition? Is there a build-up of ice on the cooling coil?
- Ductwork – Check both inside and out for mould/bacteria growth or product build-up. Are the louvres operating freely and are they free of debris?
- Drains – Is condensate pooling?
- Motors – Is there a build-up of dirt?
- Belts and pulleys – Look out for exterior cracks and signs of wear.
- Air Handling Unit (AHU) – Is there build-up on the interior, sides, wall and floor?
