Scene-Specific Solutions for Water-Scarce & Outdoor Environments

In regions with limited water resources or outdoor low-temperature applications, our Air Cooled Chiller (-5~-40℃) eliminates the need for water supply, solving key pain points:

Remote Area Cold Chain: Powers mobile cold trucks and temporary storage in deserts or mountainous areas, maintaining -15~-40℃ for frozen foods and vaccines.

Outdoor Industrial Equipment: Cools low-temperature testing chambers (e.g., for automotive parts) and outdoor refrigeration units, withstanding ambient temperatures as low as -10℃.

Laboratory Deep-Cold Experiments: Supports material science labs requiring -20~-35℃ for cryogenic testing, ensuring temperature stability with ±0.3℃ precision.

Product Design & Material Advantages

Air-Cooled Efficiency & Reliability

High-Performance Condenser: FNHM/FNVT-series air-cooled condensers with large air flow (6000~36000 m³/h) ensure efficient heat dissipation even in low ambient temperatures.

Built-In Receiver: 6~45L receivers store refrigerant, stabilizing system operation and reducing frequent refilling needs—critical for remote sites.

Durable & Weather-Resistant Materials

Compressor Body: Cast iron with weatherproof paint, resisting rain, dust, and UV radiation for outdoor use; service life extends to 12 years in harsh conditions.

Fan Motors: High-torque motors (compatible with 380~480V/50~60Hz) operate smoothly at -35℃, with low friction bearings reducing maintenance frequency.

Technical Support & After-Sales Service

On-Site Installation: Engineers travel to remote locations for installation, ensuring proper alignment of the condenser with wind direction to maximize heat dissipation.

Maintenance Training: Free training for on-site staff on cleaning the condenser (to remove dust/snow) and checking refrigerant levels—critical for air-cooled unit performance.

Spare Parts Delivery: Emergency spare parts (e.g., fan blades, compressors) shipped via DHL/FedEx, with 3-day delivery to most countries.

Energy Audit: Optional annual energy audit service to optimize operating parameters (e.g., fan speed, condensing temperature) and reduce energy costs.

Q: The equipment shuts down suddenly during operation, showing "module protection activated". What should be done?

A: First, check the cause of motor overheating (e.g., poor heat dissipation, excessive load). Repair it after identifying the cause (e.g., clean heat dissipation holes, reduce load), then restart the equipment.

Q: After ruling out motor overheating, the equipment still shuts down due to "automatic control unit protection". What needs to be inspected?

A: Focus on checking the setting parameters of the control components, such as whether the overload threshold and temperature protection upper limit are abnormal. Adjust them to standard parameters and test.

Q: If the equipment frequently triggers protection and shuts down, what preventive measures should be taken besides troubleshooting faults?

A: Regularly inspect the operating status of modules and control units, clean dust, and fasten wiring to avoid false triggering of protection due to component aging or poor contact.
