Hudson’s cleaning system allows the ability to clean induced draft air-cooled heat exchanger online while the fans will need to be shutdown in a forced draft unit. Also, tube fouling occurs from the bottom side of the tubes and unlike foams and detergents, Hudson’s system cleans from the bottom (air-side) and not from the top down. Therefore, our system is more effective in cleaning where the actual fouling is located. Also, our system is safe, environmentally friendly, non-destructive to the equipment, and proven to be the most effective in the industry at restoring unit performance. Cleaning services can be offered on a routine maintenance schedule to ensure continuous performance.
