SP Option For Optimum Performance

PLC Control

The optional control system for the SP dryer is a programmable controller with a touch screen display. The PLC controls all operations of the dryer automatically, integrating with the optional Dew Point Demand System to provide the ultimate in user friendly controls. The DPDS indicates the exact outlet dewpoint of the dryer at all times and allows the dryer to shift towers on dewpoint, rather than time.

By extending the cycle, we reduce the number of tower shifts, which extends the life and efficiency of the desiccant and valves. Additionally, there is a 4-20 mA output you can connect to a chart recorder or your computer system, and maintain a constant record of dryer performance.

The PLC controls all aspects of dryer operation. It is accessible through the touch screen display. You can simply touch the screen to monitor or control operations of the dryer. With the PLC, we are able to allow the SP dryer to emulate a heatless dryer.

If, for any reason, your primary compressor is down and you bring in portable oil-free compressors, the SP dryer can run in heatless mode and continue to receive exceptional dewpoints. You don’t need to rent a portable dryer or suffer with wet air. Sahara's SP Model takes care of you through all possibilities.
