Applications of CGH water tanks
CGH tanks allow safe storage of the following types of water:
Potable – in water supply systems, hospitals and public buildings.
Fire-fighting – reserve supply for hydrants and sprinkler systems.
Technological and process – in the chemical and metallurgical industries and the power sector.
Chilled – in refrigeration and HVAC systems.
Hot – as heat buffers in district heating and cogeneration.
Rainwater – for retention and reuse.
We adapt our designs to the specific nature of our customers’ production processes.
