Product advantages

01/

Accommodates Coolant Expansion:
As the engine heats up, coolant expands. The expansion tank provides space for this expansion, preventing over-pressurization and potential leaks or damage to the cooling system.

02/

Prevents Leaks and Overheating:
By managing coolant volume, the expansion tank helps maintain the correct pressure within the cooling system, reducing the risk of leaks and preventing the engine from overheating.

03/

Provides a Reservoir:
The tank acts as a reserve of coolant, ensuring the system has enough fluid to operate effectively, especially during temperature fluctuations or when the engine is cooling down.

04/

Aids in Circulation:
By providing a place for coolant to expand and contract, the expansion tank contributes to the efficient circulation of coolant through the engine and radiator.

05/

Reduces Coolant Hammer:
Coolant hammer, a pressure surge caused by rapid changes in coolant flow, can be damaging. The expansion tank helps to dampen these surges, protecting the cooling system.

06/

Simplifies Maintenance:
Expansion tanks often make it easier to visually inspect coolant levels and perform maintenance tasks like adding or draining coolant.

FAQ

Q: What are expansion tanks made of?

A: The expansion tank is typically made of steel or other materials designed to withstand high pressure. A rubber diaphragm or bladder inside the tank separates the air from the water. As the water expands, it enters the expansion tank and compresses the air or bladder inside.

Q: What is the most common kind of expansion tank?

A: A closed tank with a bladder or diaphragm is the most common expansion tank. This expansion tank is similar to a closed tank, except within the tank there is a bladder or diaphragm that separates the water and the air.

Q: What psi should an expansion tank be set at?

A: When a water heating cycle ends, or when any fixture is opened within the system, the impact of thermal expansion is reduced, and water drains out of the expansion tank back into the system. Expansion tanks are pre-charged with a 40 PSI air charge.

Q: Should an expansion tank be full of water?

A: No, an expansion tank should not be completely full of water. It should be partially filled with water and partially with air. The air acts as a cushion to absorb the pressure changes caused by the expansion and contraction of water in the system.

Q: How often should I drain my expansion tank?

A: This task shouldn't take very long, and should be done a couple of times a year by you or a professional.

Q: Are you manufacturer or trading company?

A: We are manufacturer.

Q: What's your best delivery time?

A: Within 15-30 days.
