ASME PVHO-1 Acrylic Windows

Pvho1 is hydrostatic pressure? Our acrylics for hyperbarics and hypobarics are unmatched and we can help with your monoplace, multiplace, or other hyperbaric window needs.

Submersible Services Lionfish Project. We are equipped with state of the art hydrostatic pressure testing equipment to handle any pneumatic testing or hydro test requirements. We will create a custom solution for any pressure vessel requirement.

Safety Standard for Pressure Vessels for Human Occupancy

The pressure exerted by a fluid at equilibrium at a given point withing the fluid, due to the force of gravity. A decompression chamber hyperbaric window will take internal pressure and is used to aske decompression sickness and other medical needs. We will also help refurbish and re-certify your hyperbaric oxygen chamber in use or hyperbaric chamber for sale. From design and fabrication to repair and hydrostatic pressure testing, Hydrospace services all types of Standard PVHO viewports and Non-Standard windows.


We serve any hyperbaric oxygen chamber used for medical, diving, testing, and other applications.

Our PVHO acrylic windows will serve any hyperbaric or hypobaric chamber needs. We can determine the ncessary geometry and thickness for your acrylic or sapphire windows to handle whatever window design pressure and temperature your application needs.

This process used in a hyperbaric chamber also known as a dive chamber involves an increase in atmospheric pressure within the chamber.

ASME PVHO-1 Acrylic Windows — Hydrospace

This process used in a hypobaric chamber involves a decrease in atmospheric pressure within the chamber, thus making the pressure relatively smaller than outside the chamber, which is what causes external pressure.

Hydrostatic pressure increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above.

Our pressure tanks can handle any geometry and mostly and size acrylic plexiglass. A recompression chamber hypobaric window will take external pressure and is also known as an altitude chamber and is used in high altitude treatment.


The chambers we serve help provide hyperbaric oxygen therapy HBOT for many patients in need. Hydrospace brings 15 years experience in the design, fabrication and certification of acrylic windows for hyperbarics and use pvno-1 Pressure Vessels for Human Occupancy PVHO.

We can create a pressure vessel design and pressure tank to handle any window design pressure and temperature.

This can be as small as consulting Hydrospace on your design to a complete turnkey solution to your pressure vessel design.
