Victorian Police
(Minehunter Style) Chamber

The Cowan Minehunter Twin Lock Recompression Chamber has been modified to suit the needs of the Victorian Police. The chamber features an onboard pneumatic lifting system for installation/removal of wheels. This chamber supports police diving operations conducted from the vessel as well as emergency treatment of decompression illness. 


Commercial Chamber

Cowan responds to a wide range of requirements for the Commercial Diving industry.  These chambers often do not have the dual gas systems (redundancy) and NATO connection capacity seen on Defence related chambers.  However, they result from many of Cowan's Defence chamber designs and benefit from its design philosophy of simplicity in design and operation. 


LED Lights

This new LED light system has been designed to be installed on existing Cowan Recompression Chambers. It features two stage illumination and a low external profile.
