Heat exchangers are used in a wide range of plants, refiners and industries and their primary purpose is to transfer energy from one fluid or gas to another without mixing the two substances. Due to their highly important role, the success of entire plant or refinery depends on heat exchangers. As integral part of some business, they can perform effortlessly or efficiently for years. However, in order to ensure the smooth performance they require maintenance mostly because heat exchangers are prone to fouling and other types of damage that significantly affect their functionality. Regular maintenance is important because it prevents more severe damage that could cost more money.
When we’re talking about heat exchanger services, the choice of company that performs maintenance is as equally important as maintenance itself. Wrong choice can negatively affect your business, cost you more money and you have to spend a lot of time on finding a suitable company that will take care of your plant’s heat exchangers adequately. Luckily, Dunn Heat Exchangers makes sure that doesn’t happen.
