PLC control systems

Supervisory control systems operate refrigeration facilities 24/7 without the need for human intervention. This automation allows facilities to run unattended, easing the demand on personnel while providing operators and service personnel with near instant access to critical updates in the event of an alarm or system failure.

Features and benefits:

• Intuitive graphical view of the complete refrigeration system
• Remote access in the event of an alarm or system failure
• Remote access for system monitoring or to address an alarm or failure

Cool Ctrl by Danfoss provides commissioning support on all supervisory control systems. Our field engineers work with customers to commission and deliver an efficient and effective control system designed to meet their needs, on-site or remotely, with long-term trouble shooting support available.

Features and benefits:

• Commissioning support on all supervisory control systems
• Onsite or remote commissioning or trouble shooting
• Long-term support available

Cool Ctrl by Danfoss ability to monitor kilowatt (kW) usage at refrigeration facilities results in reduced operator costs—by remotely shifting or shedding kW energy to non-peak hours, energy costs can be significantly cut (available option).

Features and benefits:

• Reduced energy costs while maintaining product integrity
• Works seamlessly with PLC refrigeration controls

Cool Ctrl by Danfoss control systems follow IIAR standards to maximize safety.

Alarm text/email notifications are provided to key stakeholders, e.g. operators, facility management, and service contractors, to be alerted in the event of a system alarm.

Features and benefits:

• Adherence to IIAR standards for maximum safety levels
• Alarm notifications customized to multiple parties

Historical trending allows the Danfoss Cool Ctrl portfolio to review a control system’s various data points to troubleshoot and/or adjust performance for maximized efficiency, reduced downtime, and decreased customer costs.

Features and benefits:

• Optimized system performance
• Minimized downtime
• Reduced costs

The Danfoss Cool Ctrl portfolio leverages a comprehensive software library for connecting to older screw compressor, vessel, condenser and evaporator controllers. Our legacy control system library eliminates the need to make costly replacements of older controllers that are still functioning properly.

By not replacing controllers, customers save on the cost of a new controller, labor, and expensive field wiring. Further, Cool Ctrl's by Danfoss software library enables potential older control equipment and wiring can be retained and updated with new software versions for further savings on the system upgrade.

Features and benefits:

• Leverage consultative approach of Cool Ctrl by Danfoss 
• Maximize the re-using of existing control equipment to save time and money
• Fast and easy remote access
• Reduced risk of human error with automation
• Decreased demand for personnel
• Onsite or remote commissioning
• Long-term support available on all PLC supervisory control systems

Variable frequency drive and soft starter panels are designed for both new and retrofit applications, providing a bypass option for redundancy and offering compatibility with compressors, condensers, liquid recirculators, and complete motor control centers (MCC).

From conception to implementation, Cool Ctrl by Danfoss provide components, technical expertise, and support for OEMs looking to build a complete industrial refrigeration solutions.
