AUTOMATIC TUBE CLEANING, ATC Keep your in optimal condition

AUTOMATIC TUBE CLEANING APPLICATIONS Heat exchangers are considered to be one of the largest • Process and air-condition heat exchangers power consumers in power, food & beverage, chemical, oil & gas and pulp & paper plants. Research indicates that • -based systems a layer of only 0.6 mm on heat exchanger tubes • Medium: surface, river and sea water reduces the efficiency by 34% and results in a higher power consumption of 21%. CUSTOMER BENEFITS Conventional methods such as the dosing of chemicals and manual cleaning fail to fulfill sustainability and economical goals and will • Optimal condition of the heat exchanger shut down the heat exchanger process for a longer period. • Extend heat exchanger life-time

The Nijhuis Automatic Tube Cleaning system, ATC, is the ultimate • Continuous system, reduce operational costs continuous solution to keep your process and air-condition heat • Zero environmental impact, no usage of chemicals exchanger in optimal condition and at the lowest possible costs. More than 200 customers in various industries worldwide are • Combat scaling, mussel and biofouling problems benefitting from the use of the Nijhuis Automatic Tube Cleaning in their heat exchangers.
