300 RPM - 1800 RPM Environmental Protection Equipment RCCS Condenser Online Tube Cleaning System

RCCS Real-Time Online Condenser Cleaning System with Enhanced Heat Transfer and Ceramic Bearing Technology

What is RCCS?

RCCS means the Real-Time Online Condenser Cleaning & Enhanced Heat Transfer System.

RCCS consists of spiral twisted tape, ceramic bearings and special steel supports. RCCS is installed in the condenser heat exchange tube, without additional power, driven by the flow velocity of circulating water itself. It rotates rapidly at the speed of 300-1800 RPM to achieve enhanced heat transfer and online fouling cleaning, and it can effectively increase the condenser heat transfer coefficient K value by more than 20%. There are more than 2500 power units have using this technology and have been installed RCCS®, it is one of CIMS®'s core subsystems that monitor RCCS® RPM and condenser cleanliness in real time.

RCCS Condenser Heat Transfer Enhancement System

Proprietary ceramic bearing technology and fluorinated surface treatment technology.

Online monitoring of rotational speed and remote IoT module integration.

When RCCS is used independently for cold-end energy-saving retrofit, certain requirements must be met for circulating water quality and flow rate. Water quality must comply with national industrial circulating water standards, and the circulating water volume must exceed 60% of the minimum design value.

Over 2,500 units installed, including more than 300 cases in the steel industry.

RCCS Low Hydraulic Resistance

The chart above shows the test results. The test data show that for a 12m inner polished stainless-steel pipe with an inner diameter of 18.8mm and a flow velocity of 2m/s (Re=38000), the head loss will increase by approx. 0.02-0.03Mpa with RCCS installed.

RCCS Prolongs Equipment’s Service Life

Long-term fouling in heat exchange tube easy to cause corrosion under the scale, equipment perforation, tube wear and other problems, using RCCS can not wear the pipe wall, and can not take any effects for the pipe wall, so it can prolong equipment's service life.
