Premium Thermal Expansion Tanks for Efficient Pressure Control
Fabrimech Engineers Pvt Ltd is a trusted manufacturer and supplier of high-quality Thermal Expansion Tanks in Chennai, India. Our expansion tanks are designed to handle thermal expansion in closed water heating systems, ensuring safety, efficiency, and longevity. With a commitment to engineering excellence, we offer a range of reliable and durable expansion tanks that cater to various industrial and commercial needs.

What is a Thermal Expansion Tank?
A Thermal Expansion Tank is an essential component in closed water heating systems. It helps absorb the increased water volume caused by thermal expansion, preventing excessive pressure buildup. Without an expansion tank, the system may experience stress, leading to leaks, damage, or even failure of pipes and fixtures. Installing a high-quality expansion tank ensures system stability and efficiency.

Thermal Expansion Tank Process

Water Heating
When water is heated, it expands, increasing the pressure within the closed plumbing system.

Pressure Absorption
The expansion tank, which contains a flexible rubber diaphragm, absorbs the increased volume of water.

Equalizing Pressure
The diaphragm separates the air chamber from the water chamber, allowing the air to compress and balance pressure fluctuations.

System Stabilization
By absorbing the excess pressure, the expansion tank prevents strain on pipes, valves, and heating equipment, ensuring a longer lifespan of the entire system.

Pressure Release
As water cools and contracts, the air pressure pushes the water back into the system, maintaining a steady flow and optimal performance.
