Litson Expansion Tanks Maintenance and Service Guide

Litson Expansion Tanks Maintenance and Service Guide

Litson expansion tanks are critical components that ensure the safe and efficient operation of heating and cooling systems. Regular maintenance of these tanks extends the life of the system and maximizes its performance. In this article, we will cover the maintenance and servicing of Litson expansion tanks step by step.

Why Is Maintenance Important?

  1. Safety: Expansion tanks ensure safety by absorbing excess pressure in the system. Regular maintenance ensures the correct operation of the tank and prevents potential hazards.
  2. Efficiency: A well-maintained tank increases the efficiency of the heating and cooling system, reducing energy consumption.
  3. Long Life: Regular maintenance extends the life of the tank and the system to which it is connected, preventing major failures.
  4. Cost Savings: Preventive maintenance prevents possible major failures and the high costs associated with them.

Maintenance and Service Steps

1. Visual Inspection
Visual inspection of the Litson expansion tank is required on a regular basis. During this review:

  1. Corrosion Check: Check the outer surface of the tank for signs of corrosion. Rusting can reduce the durability of the tank.
  2. Leak Check: Check the tank's ports and valves for leaks. Leaks can lead to a loss of pressure in the system.

2. Pressure Control
It is important to regularly check the air pressure inside the expansion tank. Follow these steps to check the pressure:

  1. Pressure Gauge Usage: Measure the air pressure inside the tank using a pressure gauge. The pressure should be within the values specified by the manufacturer (usually 12-15 psi).
  2. Pressure Adjustment: If the pressure is low, increase the pressure using an air pump. If the pressure is high, bleed the tank to the correct level.
     

3. Aperture Control
Litson expansion tanks have a diaphragm that separates the water and air chambers. The condition of the diaphragm is critical to the performance of the tank:

  1. Diaphragm Test: Reduce the pressure of the tank to zero and check the condition of the diaphragm. If the diaphragm is damaged, the tank may need to be replaced.
  2. Elasticity Control: Check the elasticity of the diaphragm. A hardened or cracked diaphragm can prevent the tank from performing its function.

4. General Cleaning
Keeping the area around the tank clean and tidy makes maintenance easier and extends the life of the tank:

  1. Dust and Dirt Cleaning: Keep the outer surface of the tank free of dust and dirt. A clean surface reduces the risk of corrosion.
  2. Cleaning the Connection Points: Regularly clean the pipe joints of the tank and lubricate them if necessary.

Maintenance Frequency
The frequency of maintenance of Litson expansion tanks varies depending on the intensity of use of the system and environmental factors. In general:

  1. Annual Maintenance: A comprehensive maintenance should be done at least once a year.
  2. Monthly Check-up: Simple check-ups such as visual inspection and pressure check should be done monthly.


Regular maintenance of Litson expansion tanks is vital for the safe and efficient operation of heating and cooling systems. By following the steps mentioned above, you can extend the life of your tank and avoid possible malfunctions. Remember, preventative maintenance is always more economical than repairing faults and maximizes the performance of your system.
