Water-Cooled Screw Chiller Unit

Product Introduction:

The OYRR Water-Cooled Screw Chiller Unit is a market-proven, highly stable large-scale central cooling powerhouse. The unit is equipped with world-renowned semi-hermetic twin-screw compressors, paired with Eurasia's self-developed and manufactured pressure-vessel-grade high-efficiency shell-and-tube heat exchangers. Available in single or dual compressor circuit designs depending on the required cooling capacity. Thanks to its robust cooling performance, mature manufacturing process, and low operating costs, this product has become the main force for global industrial cooling and central air conditioning in large civil and commercial buildings.

Features:

Efficient Patented Screw Compressor: Employs a high-efficiency 5:6 patented asymmetrical rotor profile and zero-clearance SKF/FAG bearings. It features a built-in differential pressure oil lubrication system for long lifespan and strong resistance to liquid slugging.

Precise Stepless Capacity Control: Features 25%-100% stepless capacity regulation or multi-stage control, tracking terminal load changes in real-time to ensure the unit consistently operates at its peak efficiency point.

High-Efficiency Heat Transfer Tech: Condensers and evaporators utilize advanced heat-transfer inner-grooved copper tubes with fully automated CNC welding. The structure is robust, scale-resistant, and strictly inspected under national pressure vessel standards.

Smart Heat Recovery (Optional): Can be equipped with partial or total heat recovery technology, capturing condensation waste heat for free during cooling. It provides free domestic or process hot water up to 70°C, boosting overall system efficiency by 5%.

Application Scenarios:

Large Commercial & Cultural Tourism Buildings: High-star hotels, massive shopping malls, theme parks, and large theaters requiring a stable and massive cooling supply.

Traditional Heavy & Light Manufacturing: Plastic molding, chemical reactor cooling, electroplating/electrophoresis bath temp control, packaging/printing, and non-ferrous metal smelting production lines demanding rigorous cooling.

Food & Pharma Engineering: Beer/beverage fermentation cooling, dairy processing, and centralized cooling for pharmaceutical GMP cleanrooms.

Large cold storage facility: Refrigeration of fruits and vegetables, precision instruments, seafood, and meat freezing

Our Advantages:

 Customization Capability: Backed by Eurasia’s strong vessel manufacturing capabilities, we can customize falling-film, flooded, or dry-type chillers based on different water qualities and working conditions, offering special anti-corrosion and explosion-proof treatments.

Safe & High-Redundancy Design: Dual-compressor models utilize completely independent dual refrigeration circuits. If one requires maintenance, the other continues to run, ensuring "uninterrupted cooling" for industrial production.

Intelligent Cloud IoT: Equipped with Siemens SMART LINE touch control panels, capable of seamless integration with BMS (Building Management Systems) and factory DCS (Distributed Control Systems).

Large-scale stable production capacity:

The company has an industry-leading large-scale production base and a complete manufacturing system. Compared with small and medium-sized manufacturers, it has a larger production capacity and more stable delivery guarantees. It can efficiently meet the demands of large quantities and multiple batches of orders, ensure a stable and reliable supply cycle, and provide solid support for the delivery of customer projects.

Comprehensive solution capability: can provide professional services covering the entire chain from selecting main equipment, planning system solutions, designing piping systems, to matching end units, optimizing the overall system, and providing technical support. It can offer precise, reliable, and efficient customized solutions according to different project conditions and customer needs, effectively ensuring the stable operation, energy-saving, and high-efficiency of the project system.
