Can the unit be designed for extreme climates?

Update Time:2025/12/17
Yes. Aurashu specializes in designing and manufacturing custom screw type air-cooled chiller & heat pump units engineered for extreme climate conditions.
With extensive experience in global projects across hot deserts, cold regions, coastal zones, and high-altitude areas, Aurashu provides climate-adaptive HVAC solutions that ensure long-term stability, efficiency, and reliability.

1. Wide Operating Temperature Adaptability

Aurashu units can be customized to operate reliably under:

High ambient temperatures up to +55°C, suitable for Middle East deserts, Africa, and tropical regions

Low ambient temperatures down to –30°C or lower, ideal for Northern Europe, Central Asia, and cold continental climates

Large day–night temperature fluctuations, maintaining stable water supply temperature

This is achieved through reinforced refrigeration circuits, optimized condenser design, intelligent defrost logic, and climate-specific control strategies.

2. Enhanced Heat Pump Performance in Cold Regions

For cold and ultra-cold climates, Aurashu integrates:

Low-temperature scroll or screw compressors

Enhanced vapor injection (EVI) or optimized economizer systems

Intelligent defrosting and anti-frost coil design

Backup electric or hybrid heating options when required

These features ensure stable heating output, high COP, and continuous operation even in sub-zero conditions.

3. High-Temperature & Desert Environment Optimization

In high-heat and dusty environments, units are equipped with:

Oversized condensers with increased heat exchange area

High-efficiency axial fans with desert-rated motors

Sand-proof coil protection and optional anti-fouling coatings

High-pressure refrigerant design to maintain cooling capacity at peak ambient temperatures

This ensures no derating or system shutdown during heat waves.

4. Corrosion & Coastal Climate Protection

For coastal, island, and chemical-exposed environments, Aurashu offers:

Epoxy-coated or hydrophilic aluminum fins

Stainless steel fasteners and anti-corrosion frames

Salt-spray-tested electrical components

IP-rated control cabinets

These measures significantly extend service life and reduce maintenance costs.

5. Smart Control for Extreme Climate Stability

Aurashu units integrate intelligent control systems that:

Automatically adjust compressor capacity and fan speed

Optimize part-load operation under fluctuating weather conditions

Provide fault diagnostics, alarms, and remote monitoring

Support BAS/BMS integration (BACnet, Modbus, etc.)

This ensures stable indoor comfort and equipment protection even in unpredictable climates.

6. Proven Global Engineering Experience

Aurashu has successfully delivered HVAC solutions for:

Power plants and energy infrastructure in Central Asia

Industrial facilities in hot desert regions

Government and commercial buildings in cold and coastal climates

Belt & Road projects with harsh environmental requirements

Each project benefits from site-specific design, simulation analysis, and factory testing.

7. Custom Engineering & Testing

Before delivery, extreme-climate units can undergo:

High-temperature and low-temperature simulation testing

Load performance verification

Electrical and safety inspections

Factory acceptance testing (FAT) tailored to project requirements

Aurashu does not offer “one-size-fits-all” solutions. Instead, every screw type air-cooled chiller & heat pump unit can be professionally engineered for extreme climates, ensuring reliable performance, energy efficiency, and long service life—no matter where the project is located.
