Case Studies Highlights
-
Gasifier Controls
-
Sherwin refurbished a 30+ year old PLC installation with a new PLC and enabled internet connectivity for alarms and the HMI interface. The installation is on a Gasifier that uses lumber yard scrap to provide heat for 10 Kilns. The gasifier generates very little ash and CO2, while providing 24/7 connectivity. Table top testing and documentation were performed prior to installation yielding a very short down time on the system.

Test Stand
-
Designed and built a pressure testing system for plastic chlorine containers. The PLC controlled system has been on line for over 11 years and provided a safe spill free work environment.
-
Diorama interactive display
-
Sherwin installed a PC and motor control system on a diorama 22 years ago. The system ran all that time with no problems. The Museum wanted to retire the Gateway computer with Windows 98 and update the system to a robust current day controller. The refurbishment uses a modern PLC with an HMI with voice over motion on the diorama.
-
The HMI panel was designed to fit the motif of the display and the nature of the Adirondacks.
-
Remediation System
-
When the current Plattsburgh Air was the Plattsburgh Air Force base, Sherwin installed 3 PLCs controlling 9 pumps, a water treatment plant, a pressure/vacuum system and a Catalytic converter on the fire fighting range. After 12 years of operation, the system removed over 95,000 gallons of JP4 fuel from the surface water. The system also included a Scada system providing current and historical data for the remediation field.
