Electrical
- 460 / 575 / 230 / 380 Volts 60 / 50 Hz
- 120 / 240 Volt single phase control voltage
- Microprocessor controller
- Operating and fail lights
- UL or CSA approved components
Central Control Electrical Panel
A custom electrical control panel allows one point hookup and may include:
- HMI ( Human Interface Device ) touchscreens
- PLC ( Programable Logic Control )
- SCADA ( Supervisory Control And Data Acquisition ) Communication Systems
- 24/7 alarm reporting to cell phones
All pump starters, fuses, disconnect, control voltage transformer, run and fail lights, are housed in a common NEMA rated panel.
Central Thermostat Control System
This system is used to control chiller units in a multiple central industrial chilling system. The temperature controller is located at the 华娱体育 tank and senses the process water temperature. The process water temperature is maintained by cycling the chiller units.
