The TICA Water-Cooled Flooded Screw Chiller – TWSF-FC Series is a premium chilled water system designed to provide reliable, energy-efficient cooling for medium to large commercial and industrial facilities. Built with advanced refrigeration technology, the unit combines a high-efficiency semi-hermetic double-screw compressor, flooded shell-and-tube evaporator, premium condenser, and an intelligent control system to ensure stable operation, low energy consumption, and a long service life.
At the heart of the TWSF-FC Series is a German-engineered double-screw compressor optimized for high adiabatic efficiency and smooth, continuous operation.
Stepless Capacity Regulation: Allows cooling output to automatically adjust according to real-time building demand.
Modulation Ranges:
Single-Compressor Models: Provide capacity modulation from 25% to 100%.
Dual-Compressor Units: Operate from 12.5% to 100%, drastically reducing energy consumption during partial-load conditions.
Advanced Oil Management: Equipped with a three-stage oil separator achieving up to 99.5% oil separation efficiency, which enhances compressor reliability and extends equipment lifespan.
Flooded Evaporator: Utilizes enhanced copper heat transfer tubes and CFD-optimized internal flow distribution to maximize heat exchange while maintaining stable refrigerant levels.
Premium Condenser: Features a high-efficiency shell-and-tube design integrated with patented oil separation technology to boost cooling performance.
Precision Flow Control: An integrated Electronic Expansion Valve (EXV) precisely regulates refrigerant flow, allowing many models to achieve Coefficient of Performance (COP) values exceeding 6.0.
Patented Automatic Oil Return: Continuously returns residual oil from the evaporator back to the compressor, minimizing wear, improving heat exchanger performance, and lowering maintenance needs.
Eco-Friendly Design: Utilizes environmentally friendly R134a refrigerant.
System operations are managed via an industrial-grade microprocessor controller paired with a 7-inch color touchscreen interface.
Dynamic Optimization: Advanced algorithms continuously optimize compressor loading, water temperature, and operating efficiency based on real-time demand.
System Protection: Features predictive diagnostics, automatic fault detection, weekly scheduling, and compressor load balancing to maximize uptime.
BAS Integration: Standard RS485 Modbus RTU communication enables seamless integration with Building Automation Systems (BAS) for centralized monitoring and remote management.
Simplified Set-up: Units feature a compact footprint, factory-installed refrigerant charges, integrated vibration isolation, and insulated components to minimize equipment room space and streamline field installation.
Hydronic Compatibility: Fully supports modern variable primary flow chilled water systems.
