Water treatment services for closed loop heating and cooling systems

Legionella testing and ACOP L8 compliance

Water treatment service for closed heating and cooling systems is essential for cost-effective plant operation.

Untreated water systems may develop microbiological fouling, corrosion and scale, which will can lead to energy inefficiency, poor system performance, and increasing risk of damage to plant and components, all leading to higher maintenance and repair costs.

Did you know?
A 1mm layer of carbonate scale build up on a heat exchanger can reduce heat transfer by up to 10%.

Hardness and softness in water present very different problems: hard water can lead to scaling, soft water can be corrosive. Solving one problem can cause another.

Understanding your water chemistry and implementing the appropriate treatment plan right is critical to ensuring safe and efficient operation of your systems and equipment.
