• Usually made of translucent material with clear liquid level scale (MIN/MAX), the coolant level can be checked intuitively and safely without opening the main water tank cover.
• Store excess coolant, and automatically replenish it back to the main circulation system when the coolant cools and contracts, so as to keep the system full all the time and avoid air resistance.
• Through liquid level isolation, air is effectively prevented from being sucked into the main circulation system. The air in the coolant will reduce the cooling efficiency and lead to internal oxidation corrosion.
• As the "expansion chamber" of the sealed cooling system, it provides extra space when the cooling liquid expands when heated, absorbs excess liquid, and prevents the pipeline or water tank from bursting due to excessive system pressure.
