FOR SULLAIR TS32/25 ROTARY SCREW COMPRESSORS

AirStarPD-SAS™ Rotary Screw Controller

As part of our AirStar® family of controllers, Case iZ offers a unique control scheme for Sullair two-stage, rotary screw compressors. The AirStarPD-SAS™ upgrade provides significant advantages over the OEM controls, delivering tighter control and increased reliability.


The controls provided with Sullair TS32/25 series compressors use a microprocessor to control the inlet and spiral-valve via mechanical/pneumatic pressure regulators. The problem is that this control scheme requires regular cleanings and fine tuning to operate efficiently. Pneumatic devices use hot, wet, unconditioned air straight off the top of the separator lid. Shuttle valves stick, regulators clog, control-line filters clog and auto-drains fill with rust and condensate. This need for continuous maintenance is the weak link.

Replacing the pneumatic control scheme with electronic controls, I/P transducers, and a modern PLC based control solution will yield noticeable results. Tighter pressure control, improved efficiency, faster system response, less maintenance, and valuable data are just some of the added benefits.


Features & Benefits


Enhanced Control Function for Electro-Pneumatic Controls

Two Analog Outputs for Sullicon Valves & Two I/P Transducers for Sullair Spiral Valve for superior variable capacity control.

Variable Speed Drive

Control is optional for Rotary Screw Compressors.

AirStarPD-SAS™ compatible with 3PX-Backbone™

Via common communication drivers, this feature enables and permits the electronic integration of Case Controllers with numerous third-party controllers.

Industry Standard Automation

Built on the Allen-Bradley line of factory automation by Rockwell, Case Controls uses ZERO proprietary parts. This means customers are free to select from a worldwide distribution network and multiple vendors for Rockwell Automation Allen-Bradley hardware.

Support

Whether on-site, by phone, or via modem connection, support is prompt, effective, and available 24/7.

Documentation

Complete new documentation sets including wiring diagrams, part’s lists, and user-manuals which tho oughly address set-up, tuning, troubleshooting and operations.

Ethernet/IP Communications

Native Ethernet/IP and Modbus communication protocol. Other protocols are optional for connection to any third-party system.
