Liquid Air Specialists
BCS's first Cryo Breathing Aparatus (CryoBA). A dual 4 liter/2 hour pack.
Dave Bush, our Nasa Biomedical lab partner, models the 1st Cryo Breathing Apparatus.
Breathing off the pack.
BCS's 1st prototype CryoASFS (Alternative Supply & Fill Station)
This unit is outfitted with a Cryomech Cryocooler allowing it to be a Zero Loss system. This unit will quickly fill 4 packs simultaneously.

All versions of our Liquid Air packs undergo rigorous human testing protocols
...maybe not all quite so rigorous
All of our packs are fitted with BCS's patented Attitude Independent Pickup (AIP) which allows for commodity pickup up to 90 degrees off-axis. A first of it's kind.

Our 2nd prototype, the 7 liter/2 hour Advanced Cryo Breathing Apparatus (AcryoBA)
This unit has proven to be a much more efficient pack in design, weight, and breathing duration. Recently a 4 liter, 1 hour version was built and human tested with great success.

Off axis human testing. One of many required protocols.
Again, all our units are equipped with the patented Attitude Independent Pickup (AIP) which allows for commodity pickup up to 90 degrees.
BCS's 1st prototype CryoRASS (Refuge Alternative Supply System)
This unit is outfitted with a Cryomech Cryocooler allowing it to be a Zero Loss system.

Please notice BCS's Zero Loss RASS system on the far left feeding, via a VJ cyrogenic hose, the LASH unit which in turn provides cool, clean breathing air to the suits.
To mix small batches of Liquid Air, BCS has developed a "Y" mixing system.
This system has been dialed in to get the satisfactory 80% Nitrogen, 20% Oxygen mix needed for safe breathing.

BCS has successfully designed a "real time" Liquid Air sampling method.
This method has the potential to provide a substantial cost and time savings.

This long established method by KSC is accurate but costly in labor hours and commodity. BCS's method is neither.
Liquid Air Pack with a battery operated fan
In an effort to utilize the cooling of the pack's heat exchanger coils, a battery operated fan was installed to help circulate cool air over the users head.

The Liquid Air pack with the fan was tested inside a level A suit on a hot Florida day (90 degrees).

The 4L/1 hour pack about to be subjected to a live fire situation.
This was the first time any of our packs were subjected to a live fire situation. They performed admirably.
The Florida State Fire College "Hot House" or "Burn Building"
Other than the pack coming out a bit less shiny, it held up to the extreme heat and smoke very well.

LCG (Liquid Cooling Garment) prototype testing
This LCG is unique in that instead of the usual supply of ice water as the source of cooling, we use the cryogenic supply.
