ADSE Dual Compressor Controller on New Gardner Denver 10hp Duplex -- Pressure Transducer Pressure Control - +/- 0.5 psi Accuracy --Options include LOL Emergency Shutdown, Auto Drain and Atmospheric Unloaders for Totally Unloaded Starts and Auto Dual Control. Installed by Air Compressor Supply of Oklahoma City, OK
ASPSS Microprocessor Controller on 25hp Champion Duplex -- Pressure Transducer Pressure Control -- +/- 0.5 psi Accuracy -- Located at the Port of New York/New Jersey Authority Maintenance Building at JFK International Includes Unloaded Starts, Automatic Dual Control, Auto Lead/Lag Control, LOP Emergency Shutdown System with Remote Send-Out, and Auto Tank Drain System. Sold by Wood Brothers Air Compressors of Hauppauge, NY.
Duplex Vacuum Pump Controller Model VASPSSFor a two 10hp pump system installed in the University of Louisville power plant. The VASPSS Controller includes two starters, microprocessor logic, pressure transducer, and automatic lead/lag switching. This VASPSS installation resulted in the lag pump shutting off all of the time, saving the University considerable operating costs and reducing system pump turning time by 50%.

Problems and failures of the building climate control system with Duplex Quincy QR Series Compressors. The addition of the ADSE-115 Universal Autodual ended the problems and added the following benefits:
1. Totally unloaded stress-free starts
2. Automatic dual control for each machine with 4 minutes time out
3. True lead/lag switching
4. Low oil pressure emergency shutdown
5. Pressure Transducer pressure control for absolute accuracy.

Major tire retailer depends on his compressors to keep his systems operating. The installation of the Universal Autodual Model ADSE enhanced the efficiency and operational capability of the system by operating only the compressor needed to produce air, having the lag compressor always ready to pick up system overcapacity and sharing the lead compressor role by switching the lead machine every two hours. Before the Autodual, this system would operate the lead machine 100% of the time, avoiding the stop required alternate to the second compressor. The single compressor would never maintain system pressure high enough to operate the tire machine. The ADSE Autodual balanced the load on both compressors, supplied soft totally unloaded starts, automatic dual control, automatic true lead/lag control and a highly efficient auto tank drain system and maintained system pressure requirements.

Special ADS on Oilless Scroll Compressor
A Special ADS on an Oilless Scroll Compressor brings automatic dual control and loadless starts for an OEM manufacturing military compressed air systems.
The ADS Universal Autodual brings timed-out high eficiency operation, eliminating too many start-stops or endless idling.
Pressure control is accomplished by a Pressure Transducer with its own display, making pressure selection a simple touch pad function.
The use of this Special Autodual resulted in a manufacturing cost saving, a much simplified installation package, along with the operational enhancement of the Autodual controller.
Unloading the compressor for the soft start and autodual control is accomplished with an atmospheric unloader.

Gardner Denver 15 hp Recip and Model ADSE Universal Autodual with Low Oil Level Emergency Shutdown with Remote Signal Feature Customer's 24 hour operation required all of the 15 hp capacity on the 1st shift, but very little on the 2nd and 3rd shifts. The Universal Autodual automatically selected constant speed for the 1st shift and then automatically timed out and stopped the compressor from excess idling in the 2nd and 3rd shifts.
