Laboratory Air Oil-Free Scroll Compressor with Enclosure and Integrated Dryer (20-30 Hp)

SPECIFICATION

Enclosed Scroll Compressor The laboratory air oil-free scroll compressor package is fl oor mounted and enclosed in a steel, sound-insulated canopy. The package is equipped with an integrated refrigerated dryer. The compressor is designed and supplied as a complete package with all necessary equipment, including but not limited to the following components:

• Inlet fi lter

• Three or Four air compressor elements

• Three or Four drive motors

• Aftercooler

• Refrigerated dryer

• Starter and regulation system

• Control system All components are mounted within a common six-sided low sound enclosure with solid base frame.

The enclosed scroll package provides air quality that qualifi es to be in the category “Class 0” in terms of oil content as defi ned by standard ISO 8573-1:2001 Part 1.

Compressor Unit Compressor Module: The compressor package is made up of three or four compressor modules, each consisting of a compressor element belt driven by an electric motor, and a radial fan mounted on the drive shaft of the compressor element. Each module is equipped with a temperature sensor to monitor the element housing temperature.

• LES20 - Four 5 Hp Scroll compressor modules

• LES22 - Three 7.5 Hp Scroll compressor modules

• LES30 - Four 7.5 Hp Scroll compressor modules Compression Element: Each compressor element consists of a fi xed scroll housing and an orbiting scroll rotor. The element and housing are pressure die cast aluminum. The crankshaft and pulley are cast iron. The element is V-belt driven using belts with ZPZ profi le. Bolts for adjusting belt tension are easily accessible via removable panels.

Drive Motor: Each compressor module is belt driven by a totally enclosed and air cooled IP55 Class F motor, complying with IE3 Premium effi ciency standards for optimum performance and reliability. The motor bearings are greased for life and do not require special attention.

Starter: Each compressor is factory equipped with a direct on line starter. The starter is mounted and wired within the UL listed compressor control cubicle.

Cooling System: Each compressor element is equipped with a radial fan mounted as part of the element to generate cooling air across the element. The compressor package is fi tted with an aluminum block aftercooler for cooling of the compressed air.

The cooling system includes a fan, driven by an electric motor, to generate cooling air for the aftercooler.

Regulation System: The compressor regulation system keeps the net pressure between programmable limits by automatically starting and stopping the compressor modules.

Compressor Control: The compressor package has a microprocessor controller with advanced graphics, capable of controlling and monitoring the modules. The unique Variable Air Delivery control system automatically starts and stops the compressor modules to exactly match the air demand. The controller distributes the running time evenly among the compressor modules by selecting the module with the lowest hours and starting that one fi rst and stopping the unit with the most run hours fi rst when applicable. The controller prevents simultaneous stopping and starting of the individual modules.

The microprocessor allows for programming of two pressure bands for loading and unloading. Time based start/stop and changeover for net pressure is programmable. The compressor is equipped with auxiliary contacts for external indication of run status, automatic or manual run control, general warning and general shutdown conditions.

The control system has the capability to control and monitor the following functions:

• Delivery air pressure

• Element outlet temperature

• Compressor status

• Motor overload status

• Delivery air temperature

• Running hours

• Regulator hours

• Ambient temperature Compressor Protection: The microprocessor provides service requirement indication, warning and shutdown indication and alarms. Additional protective functions inlcude emergency stop, element outlet temperature, drive overload, service warnings, and ambient temperature warning and shutdown.

Inlet Air Filter A paper cartridge type fi lter is provided. The fi lter has a rated effi ciency of SAE fi ne. The fi lter removes 98% of all dust particles greater than 1 micron, 99.5% of particles greater than 2 microns and 99.9% of particles greater than 3 microns in size. The inlet fi lter is factory installed.

Compressor Enclosure The compressor module is enclosed in a steel, sound-insulated canopy with removable panels to provide access for maintenance.

The sound insulating material is a fl ame retardant polyurethane.

Integrated Dryer The compressor is fi tted with an integrated refrigerated dryer.

The dryer is integrated inside the canopy and controlled by the compressor’s primary controller. The dryer uses R134A refrigerant. The refrigerant compressor is a hermetic piston type design. The dryer includes an air-to-air heat exchanger to pre-cool the incoming compressed air and reheat the exiting compressed air. The condenser has aluminum fi ns and copper tubes. The condensate is automatically drained by an electronic condensate drain.
