Wagner-Meinert provides the most efficient and reliable refrigeration control systems to the Food Process and Cold Storage industry available today.  Our custom systems are based upon industry standard equipment and software with a 100% “Open Architecture” philosophy.   This gives our customers many different choices for future modifications and enhancements to their system rather than being “locked in” to purchasing expensive proprietary equipment and software.
Here is just one example of a computer interface schematic of a plant layout with equipment locations and their operating status.
The Engine Room Screen typically displays critical information and status for compressors and vessels.  This includes compressor mode, suction, discharge and condenser pressures.  It may also display vessel alarms, pump status and refrigerant sensing alarms.
Vessel screens display liquid levels, valve and pump status, runtime hours, lead pump selection and auto switching enable/disable status.
Wagner-Meinert has developed serial communication interfaces from all of the major compressor manufacturer’s equipment to our refrigeration control systems.  Critical information on each compressor can then be viewed from a central computer screen.
The compressor’s loading and unloading is based on pressure and sequence set points.  Set points and sequences can be monitored in high or low stage operation.
The Energy Monitoring Option provides real time energy consumption data. Utility companies typically do not have this accurate or timely information available to them. Typically, utility companies takes a reading every 15-30 minutes, whereas our system continually monitors kilowatt demand, power factor demand and kilowatt-hour consumption.
In addition to monitoring, alarm set points can be established to alert you of high usage situations. Used in conjunction with the optional “Load Shedding” module, automatic control responses can be triggered to maintain specific maximum energy consumption.
