Standard Features

Premium Compressor Technology: Hanbell or BITZER (Germany) twin-screw compressors(Danfoss or Copeland scroll compressor version is available for cooling capacity below 400KW). Known for their high volumetric efficiency, minimal vibration, and rugged durability, they provide steadfast, year-round cooling for your most demanding industrial applications.
Intelligent Precision Control: Integrated Siemens PLC controller provides pinpoint mission control and comprehensive protection for both the chiller unit and your production process.
Wi-Fi connectivity module for real-time mobile app monitoring and manufacturer-assisted remote diagnostics.
Intuitive Control Interface: Siemens PLC with touch screen, offering an ergonomic, user-friendly interface for streamlined operation.
Smart Automation Connectivity: Full support for RS-485 communication protocols, seamless integration into existing plant management systems.
Top-Tier Electrical Components: Constructed with Schneider Electric parts for uncompromising electrical safety and longevity.
Robust Thermal Exchange: Equipped with high efficiency shell-and tube evaporator, ensuring high durability, simplified maintenance, and a non-contaminating fluid cooling.
Comprehensive Safety Suite: Including high/low-pressure alarms, motor overload protection, over-temperature monitoring, flow/level alarm, and phase sequence monitoring.
