Why Choose Us
Professional Team
We have a lean yet professional "core team of 8" (2 sales personnel, 3 technical personnel, and 3 after-sales service personnel), working together collaboratively with complementary skills.
Certifications
Through years of international engineering experience, our factory has the ability to produce transformers that meet IEC,IEEE,ANSI, CSA and other international standards.
Production Capacity
The refined layout of our single factory enables a seamless, closed-loop production process from raw materials to finished products. Our stable annual output of hundreds of thousands of units ensures that we can respond flexibly and promptly to market demands, providing reliable production capacity to guarantee the successful implementation of our clients' projects.
Quality Control
Every transformer undergoes a full FAT at our facility before delivery. The FAT includes routine tests according to IEC 60076, such as insulation resistance, turns ratio, short-circuit impedance, no-load/load losses, and more. Third-party witness (SGS, BV, etc.) is also available upon request.

Key Features

-
Variable Speed & Pressure Control
Continuously adjusts fan speed (using sensors) to match the cooling load. This ensures stable head pressure, even during cold-weather operations.
-
Energy Efficiency
By slowing the fan down during mild or cool conditions, the controller reduces the power used by the fan motor compared to traditional on/off fixed-speed operation.
-
Multiple Control Modes
Advanced units can control multiple fans based on saturated temperature, liquid sub-cooling, ambient temperature differences, or discharge pressure.
-
Auxiliary Fan Staging
Many controllers feature auxiliary outputs to switch on additional fixed-speed or staged fans only when high-capacity operation is required.
Type
Circuit Board Type Fan Controllers
Electronic fan speed controllers employ a miniaturised design. Their purpose is to dissipate the significant amounts of heat generated by many computer processors, graphics cards and circuit boards.
Variac Style Fan Speed Controllers
Variac devices provide fan speed control by cutting the ongoing power supply to the fan. These manually adjustable devices can control up to two fans with sufficient current.
Hybrid Fan Speed Controllers
Hybrid fan speed controllers make use of a conventional Variac-style transformer to provide variable-speed fan control. However, this is controlled by an electronic controller circuit. This means that the fan blades are less prone to oscillation and the system can also respond dynamically to changes in temperature.
Applications

Supermarkets & Retail Refrigeration
Used in centralized refrigeration racks to manage the condensing pressure of multiple fans. By using a combination of variable speed and single-speed fans, they minimize compressor power use and ensure perishable foods stay at consistent temperatures.

Industrial Cooling Facilities
Applied to massive evaporative or air-cooled condensers, variable frequency drive (VFD) controllers match fan operations to dynamic weather conditions and daily cooling loads. This achieves significant energy savings over the year.

Data Centers & Server Rooms
Fan speed controllers adjust airflow to the outside temperature, keeping data center cooling equipment stable while keeping acoustic noise at a minimum in populated or restrictive environments.

Food & Beverage Processing
Controllers manage precise temperature and pressure parameters in hygienic environments where condenser dirt build-up and fluctuating cooling loads are common, reducing stress on the system.
