    built-in logic which may be tied into the existing starter. A modification may be required from the chiller manufacturer to allow proper operation with a VFD. You may need to bypass the control logic of the existing chiller and use temperature or pressure feedback and PID to optimize speed control
  • 4-20 mA Vibration Monitoring of Chillers and Cooling Units
    4-20 mA vibration monitoring of chillers and cooling units. Cooling towers, process coolers and HVAC cooling units can be monitored for vibration using the 4-20 mA analog input channels of existing PLC units. Control system data input. Most modern chiller and cooler systems are operated
  • Manifolds for Cooling Water
    Manifolds are common auxiliaries in a plastics injection molding shop. They are key components of mold water cooling circuits. Their primary function is to route cooling water from the tower or chiller to the water passages in the mold, then collect the warmer water leaving the mold, at turbulent
