CLOSED EXPANSION TANK
 
This Korean made Closed Expansion Tank acts as a substitute of open expansion tank to prevent the corrosion of pipes. It guarantees smooth operation by completely intercepting the contact of pipe water in cooling, heating and hot water heating pipes with an air and filling proper pressure to receive and restore expansion water. This Korean made Expansion Tank is available in variety of sizes and capacities to fit your application.
 
[ FEATURES ]
 
PREVENT PIPE CORROSION
Ass contact with air is intercepted completely, air  cannot get mixed with water so the span of pipes is prolonged as corrosion is prevented.
 
WATER SUPPLY UNNECCESSARY
No make-up water is needed as no pipe water is lost by evaporation or overflow.
 
COMPLETE AIR DISCHARGE FUNCTION
The air venting system of pipe is good its pressure is properly maintained.
 
LIMITELESS INSTALLAION APPLICATION
As it can be installed in every place including basements, roof tops and mid-stories, it is not frozen to burst and space can be utilized.
 
EXTENDED OPERATIONAL TEMPERATURE RANGE
Pressure needed for pipe system can be easily maintain, so operational temperature over 100℃ from medium or high temperature water system can be easily obtained.
 
GUARANTEED SMOOTH OPERATING PERFORMANCE
Effective operation is possible without problems of pipe circulation, pump efficiency, pipe noise and vibration caused by air mixture.
 
SANITARY SYSTEM OPERATION
Hot air heating system is sanitary because hot air is not opened to the air.
 
NO MAINTENANCE IS REQUIRED
No maintenance is needed and the lifespan of tank and membrane is semi-permanent, no heat loss exists and energy is saved. The lifespan of piping in life cycle cost.
