More Than a Fan Supplier
We combine product engineering, manufacturing control and application support to help customers reduce cooling risks from development through mass production.
Engineering-Led Development
Our R&D team supports product selection, airflow evaluation, structure development and performance optimization for different equipment conditions.
Stable Mass Production
Automated and controlled production processes support consistent quality, repeatable performance and high-volume delivery.
Application-Specific Solutions
Fan configuration is developed around enclosure space, airflow resistance, noise limits, temperature range, life requirements and control systems.
Long-Term B2B Support
From samples and validation to production supply and product updates, Procool supports equipment manufacturers throughout the product lifecycle.
Performance Verified Before It Reaches Your Production Line
Procool operates a 3,000㎡ R&D laboratory supported by specialized acoustic, EMC and environmental testing facilities. Product performance is evaluated through engineering measurements and reliability testing rather than visual inspection alone.
Consistency Is Built Into Every Production Stage
Cooling fan performance depends on the consistency of every component and assembly process. Procool controls key production and inspection stages to maintain stable airflow, speed, noise and electrical performance across production batches.
"Every fan is produced for integration into another product, so dimensional consistency, electrical stability and traceability must be treated as engineering requirements."
Configure the Fan to Match Your System
Different equipment requires different combinations of airflow, pressure, voltage, noise, control and service life. Procool provides multiple configuration options across its product range.
Size and Structure
From compact miniature fans to larger industrial cooling formats.
Voltage
Multiple DC and EC voltage configurations according to the selected series.
Airflow and Pressure
Different speed levels and impeller designs for airflow or static-pressure requirements.
Bearing System
Dual ball, hydraulic and other bearing options for different operating conditions.
Speed Control and Signals
PWM, FG, RD, tachometer and temperature-control options according to model availability.
Protection
Locked-rotor protection, automatic restart, reverse polarity, overvoltage and other available protection functions.
