Competitive Components is Franchise Distributor for Cooltron Fans

Cooltron was established in 1998 in California.  Cooltron offers:

• DC Brushless Fans.  Frame size from 20~172 mm, thickness from 6~55 mm, with variety voltage design of DC 3.3/5/12/24/48V.
• DC Blowers.  Various design and voltage range of DC 5/12/24/48V for different applications.
• AC fans and Blowers.  AC 110, 220V.  115/230V dual voltage (available for some models)
• Fan Accessories.  Guards/Filters/Power Cords

Cooltron fans can be offered as an alternative to ADDA fans, Mechatronics fans, Sunon fans, Comair Rotron fans, Jamicon fans, Orion fans, EBM/Papst fans.

Fan Characteristics:

• Air Flow - The total cubit of flow moved in specified time.  Air flow is needed to determine the amount of flow required for heat dissipation.
• Air Pressure - The pressure of the flow while the fan is in static mode.  Air pressure is need to determine how much resistance created by the system.
• System Resistance - If the system resistance is small, then a fan with higher airflow and lower air pressure is needed.  If the system is large, then a fan with lower airflow and higher air pressure is needed.
• Performance Curve - The performance curve simulates different operating points to bring out the curve by performance test chamber (typically 8 pts).

Fan Mechanical

• Fan blade
• Fan frame
• Bearing

Category of Flow Direction

• Axial - The air flows along and through the shaft direction.
• Blower - The air flows in from the shaft direction and out from the radial direction.

Fan frame

• Standard frame with rib type
• Standard frame with flange type

Bearing Types

• Ball Bearing.  Advantages: 1) Suitable for low rpm, 2) high precision, 3) seal type, no oil leakage.
• Sleeve Bearing.  Advantages: 1) low cost, 2) easier production.
• Hydraulic Bearing.  Advantages: 1) suitable for high rpm, 2) long life span, 3) low vibration.

How to test fans at development stage

• Airflow / Air pressure
• Noise Level

• Abnormal noise, vibration
• Reliability test

How to test fans at reliability stage

• Life expectancy test
• High temperature resistance test
• Drop test
• Shock test
• Vibration test

How to test fans at production stage

• Electrical test (current, waveform, starting voltage, speed rpm)
• Abnormal noise
• Fan blade vibration
• 1 hour on/off burn in test and 100% check
• FQC (Finish Quality Control)
• OQC (Outgoing Quality Control)
