The TICA Water-Cooled Flooded Screw Chiller (R513A) is a premium chilled water system designed to provide dependable, energy-efficient cooling for commercial, institutional, and industrial facilities. Utilizing advanced semi-hermetic twin-screw compressors and a flooded evaporator design, the unit maximizes heat transfer efficiency while reducing compressor power consumption, resulting in lower operating costs and improved overall system performance.
The system is available in two distinct configurations to match varying building load profiles and efficiency goals:
Fixed Frequency Series (TWSF-AC5): Delivers robust, reliable cooling capacities ranging from approximately 458 kW to 1,480 kW, offering an economical solution for stable, baseline load demands.
Variable Frequency Inverter Series (TWSFV-AC5): Delivers extended capacities from 504 kW to 2,243.5 kW. It continuously adjusts compressor capacity to match precise real-time demand, significantly boosting part-load efficiency and providing ultra-precise temperature control.
Next-Gen R513A Refrigerant: Operates on a low Global Warming Potential (GWP) refrigerant, aligning with modern sustainability initiatives without compromising thermal capacity.
Flooded Evaporator Design: Refrigerant fully surrounds the heat exchange tubes to maximize heat absorption, driving up overall system efficiency.
Heavy-Duty Shell-and-Tube Components: High-performance shell-and-tube evaporators and condensers optimize heat transfer and feature removable end covers for straightforward maintenance.
German-Engineered Compressor: Built with a premium, high-efficiency semi-hermetic twin-screw compressor for extended operational life.
Smart Oil & Flow Management: Outfitted with an intelligent electronic expansion valve (EXV), high-performance oil separator, and advanced oil return technology to mitigate component wear.
Comprehensive Safety Array: Integrated protections safeguard against high/low pressure, compressor overload, freezing, discharge over-temperature, phase sequence issues, power supply faults, and water flow disruptions.
Touchscreen Interface: Controlled via an industrial microprocessor paired with a 7-inch color touchscreen for clear real-time monitoring, trend logging, and automated fault diagnostics.
Smart Integration: Built-in RS485 Modbus communication allows seamless pairing with Building Management Systems (BMS), with optional wireless modules available for remote off-site supervision.
