Energy efficient capacity control of desiccant air drying systems.
With new government efficiency targets and ever-increasing energy prices, it is DST’s policy to use new technologies wherever possible. This ensures that our products continue to use energy effectively and efficiently.
Our programmable logic control (PLC) systems will improve operating efficiency, lower carbon emissions and reduce running costs; factors that may be crucial for environmental certification.
PLCs (C2, C4 and C7) are tailored to ensure highest operating efficiency is achieved for each specific project. PLCs can be used independently, with one of our digital controllers (EH3 & EH4) or interlinked with a building management system (BMS).
adjust unit capacity to maintain required humidity, airflow and temperature.
DST’s entry level PLC type C2 is fitted as standard to all our industrial dehumidifiers. A user friendly keypad allows easy access to the menu options and a two-row backlit LCD screen displays important messages to the user. Used in conjunction with one of our humidity controllers (EH3 & EH4) or an external controller (BMS), the dehumidifier drying capacity can be finely tuned to accurately maintain the required set point.
Our PLC type C4 provides a multi-function control capability. Bespoke programming ensures efficient control of the complete drying system and its related processes.
A user friendly colour LCD touch screen provides a graphic display of the principal components with live operating data. There is easy access to menu options and the 5.7” backlit screen clearly displays important messages to the user.
The C4 offers great expansion possibilites since it is easy to add on additional functions. Using our free PC software tool, PLC operation can be monitored and adjusted remotely via the internet.
• To prevent condensation, a mounted temperature sensor provides a ‘floating’ set point for dew point control.
• Duct mounted temperature sensor can also be used for controlling air temperature.
• Communication through Modbus RTU.
