DB Series Nitrogen Generator
DB5-20 Model
2.6 Environment
DB 5-20 generators should be installed in an area where the ambient temperature is between 40°F and
95°F (4°C and 35°C). The environment surrounding the nitrogen generator should be vibration-free, dry,
and adequately ventilated. Installation of the unit in an area where the ambient temperature exceeds
these temperatures can result in performance degradation and/or permanent failure which may void
factory warranty.
Parker recommends that the generator be installed indoors in an environment that protects it from
direct sunlight, moisture, and dust. Changes in temperature, humidity, and airborne pollution will
affect the environment in which the equipment is operating and may impair the safety and operation.
It is the customers' responsibility to ensure that the environmental conditions specified for the
equipment are maintained.
2.7 Space Requirements
The equipment should be mounted on a flat surface capable as a minimum of supporting its own
weight plus the weight of all ancillary parts. There must be adequate space around the equipment
to allow airflow and access for maintenance purposes and lifting equipment. It is recommended that
a minimum spacing of approximately 4 ft. around all sides of the generator.
2.8 Connecting the Generator & Buffer Tank
Refer to Section 2.3 “Recommended System Component Layout” for the desired system configuration.
Parker supplies a nitrogen buffer tank, hoses, and a pressure relief valve with all DB 5-20 generators.
The hosing is to be used to connect the generator and the buffer tank. As noted in Section 2.5
“General Mechanical Requirements,” all buffer and storage tanks should be fitted with suitable pres-
sure gauges and pressure relief valves. The relief valve supplied is to be installed on the buffer tank.
It is recommended that ball valves be installed at each inlet/outlet port on the generator. Additionally,
ball valves should be installed at the buffer tank inlet/outlet ports to allow it to be isolated during main-
tenance activities. Connect the ball valves to the ports using PTFE tape on the threads to provide a
leak free seal.
Nitrogen is an inert, non-toxic gas. It can act as a simple asphyxiant by displacing oxygen
in air. Inhalation of Nitrogen in excessive concentrations can result in unconsciousness
without any warning symptoms such as dizziness, fatigue, etc. Install the generator in a
well-ventilated area and oxygen monitoring equipment.
WARNING
Due to the nature of operation, there is a possibility of oxygen enrichment surrounding
the generator. Ensure that the area is adequately ventilated. Where the risk of oxygen
enrichment is high, such as a confined space or poorly ventilated room, the use of
oxygen monitoring equipment is advisable.
WARNING
Note:
The right-hand side of the nitrogen generator cabinet has three ports. The lowest two ports must be connected to
the Nitrogen storage tank. The top port is the nitrogen outlet.
