Accessories | The sensors, compressors, and electrical components are all sourced from internationally renowned brands. |
Control & Display | 7-inch Color Touch Screen\PLC Controller |
Program Editing | Supports up to 5 programs, each with 50 programmable steps for preset temperature, flow rate, and pressure, enabling fully unattended testing |
Communication | CAN bus 2.0A/B (providing DBC messages), Modbus-TCP protocol (Ethernet interface), Modbus-RTU protocol (RS485 interface) |
Safety Protections | Features self-diagnostic function, overload protection, high and low voltage protection, overvoltage and under-voltage protection, phase sequence protection, low liquid level protection, anti-dry-burn protection, overtemperature protection, sensor fault, anti-freezing and anti-clogging protection, water leakage protection, earth leakage protection, and water starvation protection, etc. |
Load Power Calculation | The external load power calculation feature requires manual input of the antifreeze specific heat capacity and density parameters. |
Linear Temperature Ramp Function | Supports heating and cooling at a fixed ramp rate. |
Temperature Cascade Control | Supports direct control of external temperature points, with sensor input options including PT100, 4-20mA, and communication-based setpoint write. |
Multi-Level Permissions and Operation Logs | Featuring multi-tier user permissions, the system regulates operations and settings based on designated authorization levels, and records user actions to guarantee the security of equipment and experimental data. |
Multi-Point Sensor Calibration | Each sensor supports up to 5 calibration points and offsets, ensuring control precision. |
Data Archiving & Export | The archiving frequency is customizable (down to 1 second per log), with a storage capacity of approximately 3 months of data (at a 10-second sampling interval). Historical data, operation logs, and alarm records can be exported via USB in CSV format for viewing and editing in Microsoft Excel. |
Fully Enclosed System | The system is fully enclosed, preventing water vapor generation at high temperatures and moisture absorption from the air at low temperatures, which could otherwise raise the freezing point. |
