All about automatic brush tube-cleaning system

Chillers are used in many fields such as hospitals, airports, universities, commercial buildings and offices etc.  These chillers consume a lot of power and energy. The main goal of using chillers for maximum efficiency is that they produce fewer scales and fouling, has high heat transfer energy and there should be less shutting down for cleaning. To achieve these goals we have to do condenser tube cleaning on a regular basis that too efficiently.

 

There are many condenser tube cleaning equipment available in the marketsuch as- pressure jets and the automatic brush tube cleaning system.

 

Here is all the information you require about the automatic tube cleaning:

 

ABOUT THE MACHINE- periodic cleaning of the chiller tubes require a lot of labour and maintenance staff as well as regular shutting down of systems for a long period of time. This condenser tube cleaning method is a fast and efficient and does not require shutting down of the chillers since they are installed with the chiller itself.

 

WORKING- these automatic brush tube cleaning systems are customized according to the chiller’s piping configuration,and the four-way valve reverses the direction of water automatically for a period of 30 seconds in every 6 hours. The valve is fit into the mouth of the condenser supply and returnsto the pipe. The nylon brushes along with a cleaning chemical (solvent) are pushed through the tubes with reverse water. The brushes then clean the scaling and fouling in the tubes,and an open-ended low-pressure drop catch basket captures these nylon brushes.

 

CLEANING BRUSHES- The cleaning brushes are made from PE caps, nylon and stainless steel. They can survive and work in water of up to 60 degrees of temperature. These brushes have a life of 3-5 years and need not be replaced frequently. They come in various sizes according to the requirement,and the standard size is 10-24 mm.

 

CATCH BASKETS- the catch baskets are again made from PE and are both reusable and easy to use. These baskets come in various sizes according to requirement.

 

REVERSAL VALVE- these valves can work under a water pressure of 6 bar and a temperature of 50 degrees. The valves are made of stainless steel.

 

ADVANTAGES- the advantages of using automatic brush tube-cleaning systems are:

1.       Reduced energy consumption up to 15-25%

2.       Reduced maintenance and back-hand costs after installation

3.       Reduced water treatment cost

4.       Increased chiller efficiency

5.       No shutdown required

6.       Increased tube-life and reduced scaling

7.       Not harmful to the environment

 

Automatic machines are actually extremely advantageous to use.
