Sanyo Denki Fans for 24/7 High-Load Operation in Telecom Base Stations-Capital-Cooling fan manufacturer

Under scorching sun, high ambient temperatures, and continuous high-power output, traditional fans often fall short, leading to soaring module temperatures and even signal interruptions or equipment crashes.

The cooling challenges for telecom base stations are mainly reflected in:

Narrow air ducts, making it difficult for air to flow adequately;

Summer temperatures can exceed 60°C, creating immense cooling pressure;

High requirements for dustproofing, waterproofing, and corrosion resistance!

Faced with these severe tests, how should one choose the right cooling fan?

In telecom base stations, choosing the right fan ensures stable module operation; getting the cooling right keeps the signal online.

For selecting cooling fans for telecom base stations operating under 24/7 high load, the core considerations are reliability, long lifespan, and low noise.

Sanyo Denki's San Ace series fans are born for such harsh environments, with a rich product line capable of precisely matching the needs of different scenarios.

The following will outline several ideal choices based on their different characteristics.

High Airflow & High Reliability Choice: San Ace ST1-109S005UL

For scenarios pursuing ultimate stability and high airflow, this AC fan is a reliable basic choice, requiring no additional control circuits and simplifying system design.

（1）Core Advantages

High Airflow: Maximum airflow reaches 95.4 CFM (2.7 m³/min), efficiently removing accumulated heat inside the base station.

Ultra-Long Lifespan: Expected lifespan is up to 250,000 hours at 60°C, and even reaches 560,000 hours at 40°C, significantly reducing maintenance costs and frequency.

Wide Temperature Operation: Operating temperature range covers -30°C to +60°C, capable of handling various extreme weather conditions with ease.

（2）Key Parameters

Size: 120mm x 120mm x 38mm

Voltage/Frequency: 100V / 50/60Hz

Noise: 40/43 dBA

Intelligent Speed Control & Energy Efficiency Balance Choice: San Ace 9LG1248P1H001

If you wish to dynamically adjust cooling based on base station load to achieve a balance between energy saving and noise reduction, this DC fan supporting PWM speed control is a better choice.

（1）Core Advantages

PWM Intelligent Speed Control: Automatically adjusts speed based on device temperature and load, reducing power consumption and noise under low load, and providing full cooling power at high temperatures.

Long Lifespan Design: Expected lifespan can reach 180,000 hours at 60°C, meeting the requirements for long-term, maintenance-free operation of communication equipment.

High Airflow & Static Pressure: Maximum airflow of 176.5 CFM, maximum static pressure of 0.76 inches H₂O, effectively handling resistance from complex air ducts.

（2）Key Parameters

Size: 120mm x 120mm x 38mm

Voltage: 48V (Supports PWM speed control)

Noise: 54 dBA (at rated speed)

Choice for Harsh Outdoor Environments: San Ace Waterproof Fans

For telecom base stations deployed outdoors, facing challenges like wind, rain, high humidity, and high dust levels, Sanyo Denki's Waterproof Fans (Splash Proof Fan) offer professional-grade protection.

（1）Core Advantages

High-Level Protection: Offers various protection ratings such as IP54, IP55, and even IP68. For example, IP68-rated fans can operate normally after short-term immersion when powered off, fearless of heavy rain.

Equally Long-Lasting: Some models can also achieve a maintenance-free lifespan of up to 180,000 hours at 60°C, ensuring stable operation in harsh environments.

Intelligent Control: Also supports PWM speed control and speed pulse sensors for intelligent management.

（2）Applicable Scenarios: Outdoor telecom base stations, unattended server rooms, photovoltaic inverters, etc.

Choice for Special Air Ducts & High Static Pressure: San Ace Centrifugal / Counter-Rotating Fans

When the internal space of a base station is narrow, air ducts are bent, or cooling resistance is extremely high, traditional axial fans may be inadequate. In such cases, centrifugal fans or counter-rotating fans can play a key role.

（1）Core Advantages

Centrifugal Fans: Through a 90° airflow turn design, they can maintain strong static pressure even in high air resistance systems, acting like a "bending air courier" to make airflow smoother.

Counter-Rotating Fans: Employ two sets of impellers rotating in opposite directions (front and rear), with airflow mutually superimposing. They can provide static pressure and airflow far exceeding ordinary fans of the same size, offering a solution for extreme cooling spaces.

（2）Applicable Scenarios: High-density servers, compact communication modules, devices with complex internal air ducts.

Summary and Selection Recommendations

Sanyo Denki's San Ace series provides comprehensive cooling solutions for telecom base stations. You can match them according to specific needs:

Model/Series	Core Advantages	Applicable Scenarios
ST1-109S005UL	AC power, ultimate stability, ultra-long lifespan	Indoor base stations pursuing system simplification, concerns about control circuits
9LG1248P1H001	Supports PWM intelligent speed control, dynamic energy saving & noise reduction	Base stations wishing to dynamically adjust cooling based on load, focusing on energy efficiency
Waterproof Series	IP54-IP68 high-level protection, fearless of wind and rain	Outdoor deployed telecom base stations, power cabinets, etc.
Centrifugal/Counter-Rotating Series	High static pressure, handles complex air ducts and extreme spaces	High-density equipment with compact internal space, bent air ducts

Final Recommendations

If pursuing system stability and simplified design, the San Ace ST1-109S005UL is a reliable choice.

If you wish to achieve dynamic cooling, energy saving, and noise reduction, the San Ace 9LG1248P1H001 is more suitable.

For outdoor base stations, be sure to choose San Ace Waterproof Fans to ensure absolute reliability.

In special cases where space or air ducts are limited, consider Centrifugal or Counter-Rotating fans.
