AUTOMATIC TUBE CLEANING, ATC Keep your heat exchanger in optimal condition
AUTOMATIC TUBE CLEANINGHeat exchangers are considered to be one of the largest power consumers in power, food & beverage, chemical, oil & gas and pulp & paper plants. Research indicates that a fouling layer of only 0.6 mm on heat exchanger tubes reduces the heat transfer efficiency by 34% and results in a higher power consumption of 21%.
Conventional methods such as the dosing of chemicals and manual cleaning fail to fulfill sustainability and economical goals and will shut down the heat exchanger process for a longer period.
The Nijhuis Automatic Tube Cleaning system, ATC, is the ultimate continuous solution to keep your process and air-condition heat exchanger in optimal condition and at the lowest possible costs. More than 200 customers in various industries worldwide are benefitting from the use of the Nijhuis Automatic Tube Cleaning in their heat exchangers.

TECHNICAL DESCRIPTION
A unique Nijhuis flow diverter allows for periodic flow reversal through the heat exchanger at pre-set times, without reducing or stopping the flow through the heat exchanger and without taking the heat exchanger out of service or interrupting its operation. When the flow is reversed, the brushes will move to the other side and will clean the heat exchanger tube.
The Nijhuis Automatic Tube Cleaning system is designed to comply with specific local aspects such as water flow, water quality, diameter connection and the number of tubes of the heat exchanger. The system is installed as an integral part of the heat exchanger.
THE NIJHUIS ATC DESIGN IS INCLUDING:
• A unique Nijhuis 4 way flow diverter. The flow diverter is positioned in the piping to and from the heat exchanger.
• Two baskets with end clips and a cleaning brush. They can be applied in tubes with Ø 12 - 30 mm.
• Control panel, supported with service level agreements and i-MONITORING.
The Nijhuis ATC is a sustainable solution maximizing heat exchanger performance and extending lifetime whilst maintaining the lowest possible costs.
