Screw Type Air-Cooled Chiller & Heat Pump Unit is a highly engineered HVAC solution designed to meet specific project requirements where standard models cannot fully satisfy performance, installation, or operational needs. Unlike conventional air-cooled chillers, Aurashu’s custom screw units are tailored in terms of cooling and heating capacity, system configuration, climate adaptability, energy efficiency targets, control logic, and application scenarios, ensuring optimal performance throughout the entire lifecycle.
At the core of this system is a high-efficiency screw compressor, known for its stable operation, wide load range, and excellent part-load efficiency. Compared with scroll compressors, screw compressors are especially suitable for medium to large capacity applications, continuous operation, and projects requiring high reliability.
Aurashu’s custom air-cooled screw chiller & heat pump units integrate both cooling and heating functions into one system. In cooling mode, the unit efficiently removes heat from chilled water and dissipates it to the ambient air through high-performance condensers and axial fans. In heating (heat pump) mode, the refrigeration cycle is reversed, extracting heat from outdoor air—even under low ambient temperatures—and transferring it to the water side for space heating or process heating. With enhanced vapor injection (EVI), low-ambient operation kits, and intelligent defrost strategies, Aurashu units can operate reliably in cold regions where winter temperatures drop significantly.
Based on detailed project analysis, the unit can be customized in the following aspects:
Capacity range and configuration: Single or multiple screw compressors, dual refrigeration circuits, staged or stepless capacity control to match actual load demand.
Climate adaptability: High ambient design for hot regions, low ambient heat pump design for cold climates, anti-corrosion treatment for coastal or industrial environments.
Energy efficiency: Optimized heat exchangers, variable-speed fans, intelligent part-load control, and compliance with local and international efficiency standards.
Noise and vibration control: Low-noise fan options, acoustic enclosures, vibration isolators, suitable for urban, hospital, hotel, or residential-adjacent installations.
Control and integration: PLC or microprocessor controllers, BMS/BAS communication via Modbus, BACnet, or LonWorks, remote monitoring and fault diagnosis.
Installation flexibility: Rooftop, ground-mounted, or modular layout options adapted to limited space or complex site conditions.
Aurashu’s custom screw type air-cooled chiller & heat pump units are widely used in commercial buildings, industrial plants, data centers, hospitals, hotels, airports, shopping malls, district cooling/heating systems, and special process cooling or heating applications. Each unit is engineered to balance performance, efficiency, reliability, and total cost of ownership.
From design consultation and selection to manufacturing, testing, delivery, installation guidance, and after-sales support, Aurashu provides a full-lifecycle solution. Every custom unit undergoes strict factory testing to ensure stable operation, safety, and performance compliance before delivery. This makes Aurashu’s custom screw air-cooled chiller & heat pump units a dependable choice for demanding and non-standard HVAC projects worldwide.
