KW Designed Solutions hyperbaric chambers are used extensively by companies, who serve the offshore industry. Traditionally the name hyperbaric is used to describe any chamber or vessel, that operates above atmospheric conditions. 

Our hyperbaric chambers are ideal for simulating deep ocean pressures and the extreme, arduous subsea operating conditions that many products encounter daily.

Our hyperbaric chambers are supplied with internal diameters of 20mm to 2,500mm; with operating pressures of up to 2750 bar (40,000 psi) and temperatures from -40°C to 300°C.

KW Designed Solutions hyperbaric chambers are used for carrying out customer Factory Acceptance Testing (FAT) of their in-house manufactured components and aiding in New Product Development (NPD).

All our hyperbaric chambers can be supplied with additional features, that allow real-life simulation. They are compatible with various types of pressurisation media (water is generally the most common) but water / glycol mixes, sea water, sea water with sand and silt, oils and other liquids can also be specified.

We provide various types of pressure control systems, to control the pressurisation and depressurisation rates of the test media and to simulate the lowering of components from sea level down to the ocean depth. They are then held at pressure for a required amount of time, before being retrieved back to the surface.
