HYPERBARIC & 
HYPOBARIC CHAMBER SERIES

Hyperbaric (pressure) Chambers - for treatment of medical conditions that respond to Hyperbaric Oxygen Therapy (HBOT)

Hypobaric (vacuum) Chambers for simulating aircraft altitude conditions in pilot training

Cowan provides a comprehensive service in both the Hyperbaric and Hypobaric domains including all the essential elements of design, manufacture, installation, commissioning, training and in-service support.  This extends to full and part refurbishments.

Hypobaric Chambers  Used to simulate aircraft altitude conditions for pilot training, evaluating medical conditions at altitude, train and test pilots in altitude conditions, and simulate the rapid decompression of an aircraft.

In Hyperbaric Oxygen Therapy (HBOT) the patient is placed in the chamber under a pressure greater than atmospheric where pure oxygen is administered by a mask or oxygen hood.  HBOT treatments can be carried out in most recompression chambers, either cylindrical or rectangular in shape.  The cylindrical design is usually more cost effective to manufacture while the rectangular design, resembles a normal room, and may easily accommodate large doors.

Both a Hypobaric and Hyperbaric capability can be incorporated in the one chamber by providing both pressure and vacuum systems.  A wide range of other options are available including size, shape, pressure rating, layout, accessories and special applications.

Cowan Phuket Hospital
Hyperbaric Chamber


14 person Hyperbaric Facility - In mid 2002 Cowan Manufacturing completed the installation of a large, 2.8 metre dia, 14 person Hyperbaric Recompression Chamber into a hospital on Phuket Island, Thailand. 

The chamber system, with transfer under pressure (TUP) capacity, was designed by Cowan for both diving illness and hyperbaric oxygen treatments.  The chamber includes computerised controls, air conditioning, communications, fire fighting, monitoring and entertainment systems.

A unique aspect of the chamber is its sliding rectangular entrance door (1750mm x 1200mm) that accommodate wheel chair and stretcher patients.

The 14 person chamber can accommodate 10 people seated in main compartment with 4 in the outer compartment.  All seats can be interchanged to provide a combination of seated and bunk occupancy. 

Cowan installed the chamber and all its plant room support equipment, trained operatives and has established an ongoing in-service support program in Thailand.   The contract also included the training of Thai doctors in hyperbaric medicine in Sydney, Australia.
