Haase buffer storage with flange connections. Fact Sheet PDF

 

Operation

The water is directly put into and/or extracted from the buffer tank. During loading, the cold water is extracted from the buffer tank by the lower flange, heated, and put into the buffer tank by the upper flange. The buffer tank is unloaded by the extraction of hot water from the upper portion of the tank and input of the cooled water into the lower portion. Due to the pressure-free operation of the buffer tank , an external heat exchanger must be used for system separation.

Advantages

The buffer tank can be equipped with any number of flanges of any size.

This enables application as a hydraulic compensator and the storage and/or extraction of high energy quantities within a short period of time.

Haase multi-layer storage system 

 

The cold water is extracted by suction through the lower suction plate during loading , then heated and transferred to the multi-layer storage unit (2).

The multi-layer storage Tank facilitates the layering of the water, according to its temperature and/or density in the layer corresponding to its temperature. The hot water is extracted by suction through the upper suction plate during discharge, then cooled and transferred to the multi-layer storage unit (3).

This gives the cool water the opportunity to be layered in the lower portion of the Tank during recirculation. Due to the pressure-free operation of the Tank, external heat exchangers must be used for system separation.

Advantages:

By using the multi-layer storage Tank , even systems with comparatively low power can store their energy in a large Tanks , because the storage area is layered from top to bottom. The total system separation prevents mud accumulation in the storage vessel and permits a pressure-free storage design (no expansion vessel necessary).

Pressure Drop. Fact Sheet PDF

Pressure drop of corrugated stainless steel pipe DN 32

Flow rate should not exceed 1 m / s (equivalent to max. 5 m3 / h) as this may enable the corrugated pipe to vibrate.
