Uncompromising Build Quality

True reliability starts from within. We integrate only world-class components into our systems. Hover over the blue markers to explore the robust architecture and intelligent design that guarantee stable cooling for your critical processes.

Standard Features

Heavy-Duty Twin-Screw Compressors: Powered by authentic Hanbell or BITZER (Germany) semi-hermetic screw compressors. Engineered for continuous industrial duty, they deliver outstanding volumetric efficiency, exceptionally quiet operation, and prolonged service life compared to standard alternatives.
Next-Generation PLC Management: A built-in Siemens microprocessor continuously monitors and optimizes chiller performance. Combined with an ergonomic touch-screen interface, it ensures precise temperature regulation and maximum operational stability for your critical processes.
High-Performance Shell-and-Tube Evaporator: Designed with heavy-gauge materials to provide superior heat transfer rates, excellent resistance to fouling, and simplified maintenance for continuous, non-contaminating fluid cooling.
Optimized Air-Cooled Condensation: Features a high-efficiency finned-tube condenser array paired with low-noise axial fans. This provides maximum heat dissipation and reliable “plug-and-play” cooling without the infrastructure cost of a cooling tower.
Seamless BMS Integration: Fully equipped for smart automation with standard RS-485 communication interfaces, allowing effortless connection to your facility’s existing Building Management System.
IoT & Remote Diagnostics Ready: Includes an integrated Wi-Fi connectivity module, enabling real-time mobile monitoring and allowing our engineers to provide rapid remote diagnostic support.
Fail-Safe Protection Suite: Built-in systemic safeguards include high/low pressure switches, anti-freezing protection, compressor motor overload relays, phase sequence monitors, and water flow interlocking.

Key Components

Available Options

Inverter-Driven Efficiency (VFD Upgrade): Equip your chiller with Variable Frequency Drive technology for unmatched part-load efficiency, precise capacity matching, and significant energy savings during fluctuating production demands.
Harsh Climate Adaptability: Custom engineering available for extreme operating environments. Choose from oversized tropical condensers for high-ambient heat or specialized winter operation kits for reliable starting in sub-zero climates (down to -40°C).
Plug-and-Play Hydronic Module: Streamline your site installation with our factory-integrated pumping station. Includes custom-engineered chilled water pumps and insulated buffer tanks, fully assembled and tested for immediate system readiness.
Corrosion Protection Coating: Advanced epoxy treatments (such as hydrophilic fins or specialized anti-corrosion coatings) for the condenser coils, highly recommended for installations near coastal areas or in chemically aggressive atmospheres.
