GENERATION NITROGEN GENERATOR SYSTEM MANUAL
N2 GENERATOR COMPRESSOR CONSERVATOR CIRCUIT
The N2 Generator is rated to continuously supply a maximum of one liter/minute of N2 to the protected
space. The internal compressor is rated to operate in a maximum ambient temperature of 104°F. To ensure
maximum service life, a conservator circuit has been implemented to protect the N2 Generator and internal
compressor when/if the maximum liter/minute N2 capacity or cabinet internal temperature limits are
exceeded. The settings for this conservator circuit MUST NOT be altered or serious system damage
may occur.
The circuit monitors compressor run time. If the run time exceeds six minutes—more than adequate time to
replenish the N2 supply when the unit is supplying the rated one liter/minute gas discharge rate—the
compressor automatically shuts down and is placed in a mandatory 15 minute cool down period. After this
cool down period, the compressor is allowed to re-energize and continue replenishing the N2 gas supply in
the storage tank.
If the compressor is running with the protective circuit forcing a cool down period, steps MUST be taken to
find the cause for the excess of one liter/minute gas usage. Normally, the cause for the excessive N2 gas
usage will be a leak in the protected volume being supplied by the N2 Generator.
The compressor will also shut down if the air temperature within the N2 Generator cabinet exceeds 105°F
operating range. The compressor will remain shut down until the cabinet air temperature falls below 95°F.
If the compressor is being shut down due to high cabinet temperature, the user will experience a high
ambient temperature alarm output. Steps MUST be taken to reduce the cabinet ambient temperature.
Normally, the cause for excessive cabinet temperature will be a fault with the N2 Generator's AC cooling
unit. The user should check ALL AC filters to ensure they are not clogged and in need of replacement.
Check the AC unit to verify it is running and producing cooling air to the cabinet. If the AC unit is not running
or running and not producing cooling air to the cabinet, contact the factory at 800-338-5526.
