Product

Description:

The Low-Temperature Water-Cooled Screw Chiller is a heavy-duty industrial refrigeration unit utilizing a screw compressor as its core driving component and water as the condensing medium. Specifically engineered to deliver a Leaving Fluid Temperature (LFT) ranging from -45°C to 0°C, it serves as the primary cooling plant for large-scale central cooling systems. It is widely applied in industrial processes demanding deep cooling capabilities.

Features:

Ultra-Low Leaving Fluid Temperature (LFT) Range: Breaking the 0°C limitation of conventional chillers, this unit delivers a standard LFT of -5°C to -40°C. It fully covers the deep cooling reaction demands for pharmaceuticals and vaccines, specialized military applications, food quick-freezing, low-temperature chemical processes, and rapid manufacturing cooling.

Two-Stage Screw / Scroll Compression Technology: Utilizes a semi-hermetic two-stage compressor paired with Economizer Enhanced Vapor Injection (EVI) technology. This resolves the technical bottlenecks of single-stage compressors in ultra-low temperature applications, boosting cooling efficiency by over 30% compared to standard low-temperature chillers.

Intelligent Control & O&M: Equipped with a PLC for intelligent and precise temperature control (precision of ±0.5°C to ±1.0°C). It supports MODBUS and 4G remote communication, facilitating remote commissioning and fault diagnosis tailored for overseas clients (e.g., Middle East, Southeast Asia), and seamlessly integrates with the Ouya global service network.

Applications:

Biopharmaceuticals & Pharmaceutical Cold Chain: Low-temperature storage and cold chain logistics for vaccines/biologics; cooling for vacuum freeze-dryers (lyophilizers).

Food Quick-Freezing & Cold Chain Logistics: Tunnel blast freezing for seafood, aquatic products, and meat; industrial freezing/cooling for quick-frozen pastries and pre-made meals; centralized cooling for large-scale cold chain logistics warehouses; vacuum freeze-drying for food (lyophilized food).

Chemicals, Electroplating & Non-Ferrous Metals: Reactor cooling for low-temperature chemical polymerization, oxidation, and reduction; low-temperature thermostatic control of electroplating baths (to enhance coating quality); low-temperature cooling for non-ferrous metal smelting and rolling processes; low-temperature curing and molding of new materials (resins/plastics).

New Energy & Precision Electronics Manufacturing: Low-temperature process cooling for lithium battery electrodes/cells; low-temperature performance testing for photovoltaic (PV) solar modules; low-temperature process cooling for semiconductor wafers and chips.

Scientific Research Labs & Aerospace: Low-temperature physical property testing of materials for universities and the Chinese Academy of Sciences (CAS); extreme low-temperature environmental simulation for aerospace components; low-temperature testing for high-end equipment (bearings/engines).

Advantages:

Robust Custom-Engineering Capabilities: Leveraging full-scenario coverage and rapid bespoke customization, Guangdong Ouya Refrigeration leads the domestic market in ultra-low temperature industrial chillers. Backed by a CAS R&D team, the company operates a flexible customization system that guarantees a 24-hour response to client needs. With significantly shorter design and delivery cycles than the industry average, Ouya provides one-stop customization for ultra-low temperature conditions, industry compliance, extreme environments, and integrated installations, overcoming the adaptation barriers of general-purpose units.

Proven Application Cases: Our products are successfully deployed across seven core sectors: national defense, heavy industry, biopharmaceuticals, food & dairy, logistics equipment, new packaging materials, and university research. Ouya has served key benchmark clients, including Sanjiang Aerospace (aerospace component low-temp testing), North Mechanical Engineering (heavy industry process cooling), Livzon Pharmaceutical Group (GMP low-temp pharmaceutical processes), Jinmailang and Bright Dairy (food and dairy cooling), CIMC (modular cold chain integration), Jiangsu Ruijin Packaging (low-temp curing of new materials), and Hunan Institute of Engineering (scientific research temperature control).

Extended Supply Chain Ecosystem: Built on decades of project expertise, Guangdong Ouya Refrigeration has forged an integrated solution supply chain centered on ultra-low temperature technology. Beyond manufacturing the core chillers, Ouya can provide a full spectrum of customized ancillary components—including piping, cold storage systems, intelligent software, water pumps, insulation materials, and photovoltaic systems. This allows for the rapid, one-stop construction of a complete temperature control system, drastically reducing the project implementation cycle for clients.

Brand & Quality Assurance: Backed by a comprehensive, authoritative certification system. In addition to Chinese National Standard (GB) quality endorsements, our products hold top-tier international certifications such as EU CE/A+++, Halal, and German BAFA. This demonstrates our global compliance capabilities, ensuring access to mainstream worldwide markets and eligibility for European policy subsidies.
