Hitachi 190 Water Cooled Chiller

BASIC INFORMATION

1. Advanced High-Efficiency Screw Compressor

Precision Engineering: The asymmetrical twin-screw rotor profile is machined with extreme precision, minimizing internal leakage and maximizing compression efficiency.

Capacity Control: Smooth and continuous capacity control is achieved through a sliding vane mechanism, allowing the chiller to match the building load exactly without the energy losses of start-stop cycling.

Reliability: The compressor has few moving parts and operates with minimal vibration, leading to exceptional longevity and reduced maintenance.

2. Superior Energy Efficiency

Hitachi RCU chillers are designed to achieve best-in-class energy performance.

Low Full and Part-Load Power Consumption: The efficient screw compressor, combined with optimal heat exchanger design, results in very low kW/ton ratings, both at full load and, crucially, at the part-load conditions where chillers operate most of the time.

Integrated Inverter Option (VFD): Many RCU models are available with or can be equipped with a Variable Frequency Drive (VFD). The VFD precisely controls the compressor motor speed to match the cooling demand, delivering significant energy savings, especially during low-load periods.

3. Intelligent Control & Monitoring System

Hitachi AI Controller: The chiller is managed by a sophisticated microprocessor controller that provides:

Auto-Tuning: Automatically optimizes operation for maximum efficiency under changing conditions.

Comprehensive Diagnostics: Monitors all system parameters, provides detailed fault logs, and alerts operators to potential issues.

User-Friendly Interface: Features a clear display and simple navigation for easy operation and system status checks.

Remote Connectivity: Allows for remote monitoring and control, facilitating integration into Building Management Systems (BMS) via protocols like BACnet.

4. Robust & Service-Friendly Design

Compact and Rigid Structure: The unit is built with a heavy-duty frame and chassis, ensuring stability and reducing noise.

Easy Maintenance Access: Key components like the control panel, oil separator, and strainers are designed for easy access, simplifying routine maintenance and reducing downtime.

5. Environmental Responsibility

Wide Range of Refrigerants: The RCU series is designed to operate with various environmentally responsible refrigerants, including H and next-generation , ensuring compliance with global environmental regulations.
