Model AS2PT

The AS2PT does the job of complete control for two GAST pump systems. The AS2PT controller includes two starters, accurate pressure control with Pressure Transducers and Automatic Lead/Lag control every 24 hours resulting in balanced operating loads for the two Gast pumps. In the event that the lead compressor cannot handle the plant capacity, the lag pump will automatically come on line to pick up any excess load requirements. When the requirements have been satisfied, the lag compressor will shut itself off.

 

AS-2

The AS-2 Universal AutoSync automatic lead/lag controller installed on the Atlas Copco duplex small rotary compressor package supplies automatic lead/lag control for the two compressor system.  Systems built by HB Compression, Conroe, TX.

ADSE-115 Controller at Natural Gas Station in PA

The ADSE-115 controller is installed in an existing natural gas plant's unattended compressor building. Installed by the C.H. Reed Co., this ADSE is controlling two Curtis 98 base-mounted compressors and theAuto Lead/Lag Control is set to switch the lead compressor every 5 hours. Automatic dual control and totally unloaded soft starts are features that were required by the customer, Enmacon Service Corp.of Johnstown, PA. Note the all stainless steel control air piping.

The absolute reliability of the Universal Autodual controller is a basic requirement for this critical installation to maintain the stability of the natural gas plant.

Pressure Switch Connection

 

The installation is very simple:

1. One wire goes to the pressure switch;

2. Two wires go to the starter coil on each compressor;

3. Set up -- Designate compressor 1 and compressor 2. Set the pressure on compressor 2 to at least 10 psi lower than compressor 1. That was accomplished by turning the pressure switch adjustment screw 3/4 of a turn counter clockwise on compressor 1.

The AutoSync features that are important to Mavis include:

1. True lead/lag control that alternates the two compressors on the clock, which for Mavis was one hour.

In the event that the lead compressor cannot hold the plant load and the system pressure falls to the "start" pressure of the lag compressor, the lag compressor will start and assist the lead compressor in meeting the increased air demand. The AutoSync brings true lead/lag control to the operating system and makes both compressors available for use automatically.

One common problem with the standard alternator is a system where the operating air compressor is barely meeting the plant demand and NEVER gets to its shutoff pressure. The result of that is the continuous running of one machine that compromises the motor, starter and compressor integrity and puts the compressor manufacturer in warranty jeopardy. Since we FORCE the alternation, this situation will never happen with the AutoSync.

2. Hour meters. No company has hour meters (or true lead/lag control) available for their standard recips. The two hour meters allow the customer to balance the load on both machines and is a sure method of indicating maintenance periods.

 

Universal AutoSync

The Universal Autosync has applications beyond the standard air compressor lead/lag functions. Shown is an installation of the AutoSync integrated into the controls of a two stage water chiller. The AutoSync effectively lead/lags the two water chillers based on chrono time and allows the lag cooler to be accessed automatically if the load duty requires its operation. This is installed at a National Fish Hatchery in Idaho.

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

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.
