You’ve paid to have an evaporative cooling system to be installed quite recently, so how come it needs servicing already?
The answer is that it’s the nature of evaporative cooling, rather than the particular air cooling system installed, that means it needs regular servicing.
What is evaporative cooling?
An evaporative cooling system works by passing warm air from outside a building over filter pads that are kept saturated in water. This makes it a much cheaper more environmentally friendly way of cooling spaces in comparison to air conditioning. Only pure water is evaporated from the pads and the water is drained on a regular basis. These systems consume water, however you can reduce the water consumption of a system through proper maintenance, which subsequently reduces the cost of power needed for the system to run.
Ensuring your evaporative cooling system is running safely and efficiently
In order to ensure that all of the systems parts are functioning properly and to help identify any potential problems as quickly as possible, it’s necessary to maintain an evaporative cooling system on at least a 6 monthly basis. It is essential to inspect and clean a unit as dust and dirt can build up in the water reservoir which can cause contaminated air to be circulated around the workplace. This air could potentially cause respiratory problems in staff including a Legionella outbreak.
What is Legionella and should I be worried about it?
Legionnaires disease is a potentially fatal form of pneumonia and affects nearly 250 people in the UK each year.
Legionnaires disease naturally occurs in soil and water environments at low temperature (under 20C) and it thrives at temperatures between 20 and 45C. The Legionella bacteria infect the body through inhalation of contaminated water droplets.
How to prevent Legionella
By law, if you have a cooling system, you will need to complete a Legionella Risk Assessment. During the Winter months cooling systems are usually turned off as they are no longer needed within the workplace, and this then causes a bacterial build up on the pads and in the water reservoir that can include Legionella. This then becomes active as the warmer spring weather arrives.
Our specially trained engineers at Vent-Tech are trained to be able to complete an ACOP Legionella Risk Assessment and service our, or other companies’, evaporative cooling systems – so please get in touch to see how we can help support your staff’s wellbeing and ensure your system is running efficiently.
