Fizz Nitro-Draught 1200 - Unit Description & Features

SECTION 3
Unit description & features
The Nitro-Draught 1200 blend gas dispense system extracts nitrogen (N
2
) from ambient air, blends it
with carbon dioxide (CO
2
) and supplies the mixed gas to a draught beer system. As a component of a
properly designed and maintained draught system, the Nitro-Draught 1200 assures brewery quality
beverage presentation while it eliminates excessive foaming and wasted beer.
The Nitro-Draught 1200 system uses proven Pressure Swing Adsorption (PSA) technology with
Carbon Molecular Sieve (CMS) to separate N
2
from the atmosphere and store it at a purity level of at
least 99.8%. It uses a mechanical blender to combine the N
2
with CO
2
from another storage vessel
into CO
2
/ N
2
“beer gas” blend ratios, commonly two blends are used, 25% / 75% and 60% / 40%.
Blends can be customized for any application. Pure nitrogen can be withdrawn directly from the
storage tank to use in inert wine dispense equipment.
While in Production Mode, the internal air compressor will cycle on and off on approximately two
minute cycles. Each compression cycle will be followed by an exhaust cycle. At the start of the
exhaust cycle, an audible release of internal air pressure will occur. This compress-exhaust
alternating cycle will continue until the unit fully pressurizes the storage tank. At that point the unit will
move into Economy Mode, and power down all internal components after a few minutes. The Nitro-
Draught 1200 will enter into Economy Mode at 100 psi tank pressure and then return to Production
Mode when the tank pressure drops to 90 psi, as nitrogen is used.
This manual contains the information necessary for the correct use of the Nitro-Draught 1200.
