DESCRIPTION GENERAL The Powerex Laboratory Enclosed Scroll Air Compressor System is designed to provide clean, dry air for applications where the quality of the compressed air is critical and a quiet enclosed compressor set is desired. The standard unit is rated for a maximum of 116 PSIG. Each system includes multiple oil-less scroll compressors in a sound reducing enclosure or multiple enclosures, corrosion resistant air receiver, desiccant air dryers with purge control, a control panel and integrated dew point monitor. Systems are also equipped with dry type inlet filters, aftercoolers internal to the enclosure, check valves and ball valves for each pump. The air receiver tank has an automatic no-loss condensate drain and manual back up drain. The twin tower desiccant dryers are installed with ball valves and sized so that one dryer can meet full system flow needs. Final regulators are factory installed and set for a stable final pressure. A dew point monitor is included to provide feedback and control of the dryer option. Various options are available to make the system suit your needs, including a CO monitor or remote air intake capability. The Powerex scroll air compressor has advanced scroll compressor technology through the development of a completely oil-less unit. The Powerex Scroll Compressor offers a dynamically balanced air end and rubber isolated pump motor assemblies which insures vibration-free operation. The rotary design permits a continuous 100% duty cycle. No oil separation, oil filtration, or inlet valves are required on the Powerex scroll unit. The compressor is virtually maintenance free. Laboratory Air Enclosed Scroll Systems (Simplex and Duplex) Operating Voltages Control Panel Pressure Settings ASME Rated for 200 psi MAWP Systems are available with advanced PXMI touch screen controls to allow operation and monitoring of the unit. The systems utilize a programmable logic controller (PLC) to operate the number of pump motors required to meet demand. If the system consists of multiple units, the main control automatically alternates the units to equalize usage.

Enclosed Scroll Laboratory Air Systems The Powerex oil-less rotary scroll air compressor is based on the theory of scroll compression. A scroll is a free-standing, intricate spiral bounded on one side by a solid, flat plane or base. A scroll set, the basic compression element of a scroll compressor, is made up of two identical spirals which form right and left hand parts. One of these scroll components is indexed or phased 180o with respect to the other so the scrolls can mesh. Crescent-shaped gas pockets are formed and bounded by the spirals and the base plate of both scrolls. As the moving...

Enclosed Scroll Laboratory Air Systems compressor units themselves are rated for operation at ambient temperatures up to 104oF, but that as part of an Enclosed Scroll Laboratory Compressor system, the ambient temperature around the compressor cabinets must be limited to 85oF. Operation in higher temperatures will result in reduced dryer performance. filter and after filter have differential pressure indicators to signal when the filter elements are in need of replacement. The desiccant dryers have purge air silencers. Do not restrict the flow through these silencers or modify them as dryer performance...

Enclosed Scroll Laboratory Air Systems INSTALLATION SITE 1. The compressor system must be located in a clean, well lit and well ventilated area. 2. The area should be free of excessive dust, toxic or flammable gases and moisture. 3. Never install the compressor system where the surrounding temperature is higher than 85°F or where humidity is high. 4. Clearance must allow for safe, effective inspection and maintenance. DEW POINT MONITOR The Powerex dew point monitor provides indication of dew point temperature. It’s microprocessor is controlled with alarm and self-calibration sensor. Regen dryers...

Enclosed Scroll Laboratory Air Systems The Enclosed Scroll Laboratory Air Compressor units may be placed directly onto a solid floor. Composite cork and rubber isolation pads may be placed under of the corners of the frame if desired, but the internal moving parts are already rubber isolated from the frame. If fixing bolts are desired, use the L brackets that secure the frame to the shipping skid as mounting brackets. The tank dryer skid may also be placed directly on the floor or installed with pads at the corners. If desired, fixing bolts may be installed through the holes provided. Remote...

Enclosed Scroll Laboratory Air Systems 2. Some systems consist of multiple modules. The steel frames are intended to be bolted together using the supplied fasteners and connecting hoses provided (found in the parts pack box with the isolation pads). Modules may be spaced farther apart without any structural problems, but electrical connections may need to be modified—additional isolation pads and longer hoses may be needed. Place modules at location designated. Provide sufficient clearance around unit for servicing (see minimum clearance section). Install frame assembly fastners to each frame...
