Pollution poses a threat to chiller performance, as the condenser is vulnerable to a number of common pollution-related problems. Alfa Laval is finding new ways to ensure chiller protection by incorporating its efficient heat exchanger into economical and eco-friendly free cooling-based solutions.
Pollution impairs performance
A polluted operating environment increases the risk of a chiller shut down due to condenser impairment. As the condenser is highly vulnerable to attacks from corrosive chlorides, fouling impurities and biological activities in the water, there is a need to provide cost-efficient chiller protection.
Free cooling’s role in protecting chillers
Alfa Laval gasketed heat exchangers can be used to provide economical and highly effective condenser protection for chillers. In combination with a cooling tower or a free cooling source, such as a river or lake, our plate heat exchangers create an indirect system for chiller protection. This solution compared to a direct system where the cooling source is in direct connection with the chiller, eliminates pollution related problems and as a result improves condenser reliability and reduces maintenance costs.
