Description
APPLICATION
 WATER SUPPLY
In booster systems, vessels are used as buffer tanks to immediately store the difference between the pumped volume flow and the volume flow
actually needed. 
Vessels are also required to decrease the switching frequency of a pump and reduce peak loads.

 SANITARY HOT WATER
When heating sanitary water, pressure rises as the water expands. In the worst case, the excess pressure is decreased by a safety valve, losing valuable heated potable water. The use of IWM pressure vessels remedies this situation by preventing the unnecessary opening of the safety valve and providing for a more efficient, resource-conserving operation of the system.

 HAVC
In closed heating-cooling systems, the water expands or contracts as the system is heated up or cooled down. Expansion vessels are used to compensate for the fluctuations in volume between MAX and MIN temperatures within a permissible range.
IWM pressure vessels are used to maintain pressure in heating, cooling, and solar power systems. The pressurized cushion of gas supports the water column within the system and is set before a reserve of water is poured into the vessel. When the system heats up, the pressure rises and expansion water flows from the external system into the water space: the pressurized cushion of air in the gas space is compressed. When the system cools down and its pressure drops, this counter pressure pushes water from the membrane back into the system. This releases the pressurized cushion of air in the gas space.

COMPARISON


OPERATING CYCLE
  Initial State Of The Tank

           4 bars precharge pressure in the membrane.

              NOTICE: Tanks shipped outside the continental EU and China are not pre-charged.
  Water Begins To Enter The Tank

           Air is compressed in the membrane as the tank fills with water.

 Pump-Up Cycle Completed

           air pressure has reached the cut-off setting of the pressure switch.

 Water Being Drawn From The Tank

           Compressed air in the membrane forces water out of the tank.

 Tank Now Empty

          new cycle ready to begin.

Pressure Regulation for Optimal Performance
The IWM Expansion Tank is specifically engineered to absorb the increased pressure caused by thermal expansion in water heaters. By doing so, it ensures that the system remains under safe pressure levels, thus preventing damage and improving the longevity of your water heater.


Prevents System Overload
When water is heated, it expands, increasing pressure in the water heater. The IWM Expansion Tank helps mitigate this by absorbing the excess pressure, preventing strain on the system and reducing the risk of overheating or malfunctioning. This feature is particularly important in maintaining the safety and functionality of your water heating systems.


Durable and Reliable Construction
Built with high-quality materials, the IWM Expansion Tank offers durability and reliability. Its rugged construction ensures long-term performance even under high-pressure conditions, making it an ideal choice for commercial installations where durability is paramount.


Easy Installation and Maintenance
The IWM Expansion Tank is designed for easy installation in residential and commercial heating systems. It can be integrated seamlessly into existing water heaters, and routine maintenance is straightforward, ensuring your system remains in optimal condition for years to come.
