PRODUCT HIGHLIGHTS
- *High-Velocity Pressure Barrier: Our centrifugal air curtain creates a powerful, high-speed invisible air wall that effectively blocks up to 90% of heat transfer, ensuring stable indoor temperatures for warehouses and cold storage.
- *Superior Energy & Thermal Protection: By preventing the loss of conditioned air, this unit significantly reduces the workload on HVAC and refrigeration systems, leading to substantial energy savings and lower operational costs.
- *Rugged Industrial Durability: Engineered with a robust all-metal casing and a heavy-duty centrifugal motor, our air curtain is built to withstand harsh industrial environments, offering reliable performance with a long service life.
- *Effective Insect & Dust Control: The high-pressure airflow acts as a relentless shield against flying insects, dust, and outdoor pollutants, maintaining a clean and hygienic environment for food processing and medical facilities.
- *Intelligent Low-Noise Operation: Despite its high-power output, the precision-balanced centrifugal fan wheel ensures smooth operation with reduced vibration and noise levels, suitable for both commercial and industrial settings.
- *Versatile Installation & Customization: Designed for easy mounting over large industrial doors, it supports various widths and heights. Ideal for logistics centers, supermarkets, and factories requiring frequent door operation.
FAQs
What is the primary difference between a centrifugal and a cross-flow air curtain?
Centrifugal air curtains provide significantly higher air pressure and velocity. They are designed for large industrial openings or locations with high wind pressure, whereas cross-flow types are typically for smaller, commercial shop entrances.
How do I choose the correct size for my industrial door?
The air curtain should be equal to or slightly wider than the door opening. For heights over 3.5 meters, a high-power centrifugal model like ours is essential to ensure the air barrier reaches the floor effectively.
Can this air curtain really save energy in my cold room?
Yes. When the door is open for loading, the air curtain prevents cold air from escaping and warm air from entering. This maintains the set temperature and reduces compressor run-time, saving up to 30-40% on energy bills.
Is the motor capable of 24/7 continuous operation?
Absolutely. We use industrial-grade motors with high-temperature resistance and high-quality bearings designed for continuous use in busy logistics and production environments.
How effective is it at stopping flying insects?
It is highly effective. The strong downward air pressure is too powerful for most flying insects (flies, mosquitoes) to penetrate, making it an essential tool for HACCP-compliant food facilities.
Does the unit require professional maintenance?
Maintenance is minimal. We recommend checking and cleaning the air intake and the fan wheel every 3-6 months to prevent dust buildup and ensure maximum airflow efficiency.
Can I customize the voltage for my country's power grid?
Yes, we support various voltage and frequency configurations, such as 220V/50Hz, 380V/50Hz, or 110V/60Hz, to meet the electrical standards of your specific region.
What is the noise level during full-power operation?
While industrial centrifugal units are more powerful, our fans are precision-balanced to minimize vibration. Noise levels typically range from 60-70 dB, which is standard for industrial-grade airflow equipment.
