Description
The Powerex medical system package is designed to provide medical breathing air for hospital and medical institutes.
This system meets NFPA 99 requirements for Level 1 breathing air.
OILLESS OPT/OPS COMPRESSOR
The Powerex oilless reciprocating air compressor has advanced compressor technology through the development of a completely oilless compressor. The Powerex reciprocating compressor is provided in duplex, triplex or quadplex configurations with head unloaders to provide start, stop or continuous operation. Composite piston technology and continuously lubricating bearings provide
RECEIVER TANK
The ASME, National Board registered air receiver is provided in sizes from 120 to 240 gallons. Each receiver is rated at 200 PSIG working pressure. Receivers are provided with sight glass and moisture drain (manual or automatic).
CONTROL PANEL
The NEMA 12 control panel is provided in duplex, triplex or quadplex configurations and meets NFPA 99 requirements for medical air. Primary voltage is protected by fusing or circuit breaker. Control transformer power is 110 volts and protected by secondary fusing. Pressure control switches signal the compressors on and off cycle and signal lag compressor(s) to come on if air demand increases. A lag, lag pressure switch or transducer signals a light and audible alarm warning of a low pressure condition which is factory set at 40 PSIG. An acknowledge button is provided for start condition and maintenance. The adjustable timer alternator cycles each compressor so equal run time is maintained. This alternator is factory set to alternate the compressors every 10 minutes. The exterior of the control panel is accessible through the door. The panel disconnects on/off/auto switches run lights, power on lights, run hourmeters, lag pressure light, high
temperature light and overload reset. This control panel is UL listed.
DEW POINT MONITOR
The Powerex dew point monitor provides indication of dew point and temperature. It’s microprocessor controlled with user programmable output range, alarm and calibration. The NEMA enclosure is protected by a polymer viewing cover.
CARBON MONOXIDE
MONITOR/ALARM
The carbon monoxide monitor provides warning to the user of
AIR COOLED AFTERCOOLER
Four models of beltguard aftercoolers sized to provide an approach of 20°F. Constructed of copper tubing and metal headers for a rugged construction.
AIR DRYER (REFRIGERATED OR DESICCANT)
The Powerex air drying system provides air at 38°F at 100 PSIG for refrigerated units and
The refrigerated compressed air dryer(s) are noncycling, direct expansion type, using
CFC free. A hot gas bypass valve is provided to maintain 38°F evaporator temperature. The dryer is self- regulating for large load swings. Heat exchangers are made of copper tube construction and insulated.
The regenerative desiccant consists of two (dual) towers filled with desiccant. Each tower is switched on and off stream, alternating the air system stream and then being regenerated. Dry purge air pulls moisture from the desiccant and carries the moisture out of the air.
MEDICAL FILTER SYSTEM
The medical filter system consists of a duplex series of filters and pressure regulators. Air enters the system and is directed to either bank of filets controlled by ball valve. The first stage filter removes solids and liquid particles. The next stage of filters remove submicronic particles and aerosols. The third and final filter is carbon activated to remove unpleasant odors. Maximum operating temperature is 125°F and maximum pressure is 150 PSIG.
CONDENSATE DRAIN VALVE
A condensate drain valve must be installed on any tank. This valve removes liquid that collects during compressor operation.
Drain liquid from tank daily.
