SENHO VRA Series air cooled scroll chiller

Standard Features

Premium Scroll Compressors: Equipped with world-renowned scroll compressors (such as Copeland or Danfoss) for high efficiency, quiet operation, and exceptional reliability in demanding continuous-duty applications.
“Plug-and-Play” Installation: Integrated hydraulic module, including an oversized reservoir and high-flow pump for easy deployment.
Robust Thermal Exchange: Equipped with an integrated SUS304 coil-in-tank evaporator, ensuring high durability, simplified maintenance, and a non-contaminating fluid cooling.
Energy-Saving Staged Operation: Engineered with independent refrigeration circuits. Our intelligent load-matching logic activates only the necessary compressor stages based on real-time heat loads, significantly reducing your facility’s energy consumption.
Corrosion-Free Fluid Circuit: Standard on models PRA025L2 and below, featuring non-ferrous water circuit parts.
Intuitive Control Interface: Smart controller engineered by SENHO specifically for industrial cooling, 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.
Comprehensive Safety Suite: Including high/low-pressure alarms, motor overload protection, over-temperature monitoring, flow/level alarm, and phase sequence monitoring.

Key Components

Available Options

Ultra-Precision Temperature Control: Advanced logic and valving upgrades available to achieve an industry-leading ±0.1°C temperature accuracy for highly sensitive manufacturing processes.
High-Capacity Hydronic Upgrades: Custom-engineered water pumps to provide increased flow rates and higher delivery pressures, easily overcoming resistance in complex or long-distance piping networks.
Dual-Circuit Design: Purpose-built for applications requiring a high delta-T (large temperature difference) process cooling solution.
Extreme Climate Adaptability: Specialized configurations and robust component selection guarantee rated performance in extreme ambient temperatures, ranging from -40°C up to 65°C.
Advanced Siemens PLC Upgrade: Replace the standard controller with a Siemens PLC and intuitive touch-screen interface for pinpoint mission control and complex system automation.
IoT & Remote Diagnostics: Add a Wi-Fi connectivity module for real-time mobile app monitoring and rapid, manufacturer-assisted remote troubleshooting.
