2.2.9.2
Liquid Phase
Liquid phase monitors shall be provided [where indicated on the drawings]
[on the effluent line of the last reactor]. Sensor shall transmit output
to an ozone analyzer with digital display and remote signal transmission to
the central control unit. Probe shall transmit output to a liquid phase
ozone analyzer with digital output. The liquid phase ozone analyzer shall
transmit a [[4 to 20] [_____] mA signal proportional to the ozone
concentration] [direct digital reading] to the central control unit.
2.2.10
Temperature Sensors
Temperature sensors shall be dual switch trip point independently
adjustable type with a minimum accuracy of 0.5 percent of full scale.
Thermal system shall be constructed of 316L stainless steel. Temperature
range shall be from [0 to 100] [_____] degrees C [32 to 212] [_____]
degrees F and suitable for the medium monitored. Sensor shall transmit
output to an analyzer with digital output. The analyzer shall transmit a
[[4 to 20] [_____] mA signal proportional to the temperature] [direct
digital reading] to the central control unit.
2.2.11
Compressors
Air compressors shall conform to ASME B19.3. Air compressors shall be
factory packaged [rotary screw] [centrifugal] [rotary] [reciprocating] type
units. The air compressors shall be packaged in an enclosure with sound
attenuating properties which allow a maximum noise level measurement of 75
dBA at the equipment enclosure. Air compressors shall be [water] [air]
cooled and rated for continuous operation. Guards shall shield exposed
moving parts. Compressor motors and starters shall conform with the
requirements of Section 16402 INTERIOR DISTRIBUTION SYSTEM. Air
compressors shall have the manufacturer's name and address, together with
trade name, and catalog number on a nameplate securely attached to the
equipment. Any special maintenance instructions (required before startup
or shutdown) shall be included in the Operations and Maintenance Manuals.
Compressor equipment used for processing ambient air for the ozone
generator feed gas shall include the air compressor, receiver with
automatic condensate drain, intake air filter and silencer, after cooler, a
high efficiency moisture separator, [refrigerative dryer], pressure,
temperature and moisture monitors, local controller and other equipment as
required by the manufacturer to provide a complete and operational oil
free, dry compressed air system. Compressor receivers, air piping, valves
and appurtenances unless otherwise specified, shall be in conformance with
Section 15400A PLUMBING, GENERAL PURPOSE. Dry contacts and 4 to 20 mA
signals shall be provided in the control panel for remote monitoring.
