Compressors: The Heart of the System
Our compressor range includes rotary, scroll and inverter types from brands such as LG, Samsung, Copeland, Panasonic, SANYO, Daikin, GMCC and Hitachi. We supply compressors for residential and commercial AC units, with capacities from 9,000 BTU to 30 HP. Each compressor is selected for efficiency, reliability and compatibility with refrigerants such as R410A and R134A.
When specifying a compressor, we consider cooling capacity, voltage (e.g. 220V/50Hz or 208V/60Hz), refrigerant type and the physical dimensions of the unit. Our team can help match the correct compressor model to your system requirements.
Capacitors: In-House Manufacturing Expertise
We are a dedicated manufacturer of metalized polypropylene film capacitors, with an annual production capacity of 10 million units. Our capacitors are used in AC compressors and fan motors to provide starting torque and improve power factor. We produce CBB65 series capacitors with metal cases, plastic insulation and oil impregnation, available in various capacitance and voltage ratings.
In-house production allows us to control quality closely. We use high-precision slitting and winding equipment to ensure consistent film tension and layer alignment, which is critical for capacitor reliability under high inrush currents. Each capacitor undergoes testing to verify capacitance, insulation resistance and withstand voltage.
Control Systems and Electrical Components
We supply universal A/C control systems and remotes that can replace original parts across multiple brands. These systems include wired and wireless controllers, as well as receiver boards. Our contactors, transformers, relays and overload protectors are rated for the electrical loads of typical AC units, ensuring safe and reliable switching.
For temperature management, we offer thermostats and temperature controllers with various sensing ranges and switching capabilities. These components are essential for maintaining setpoint accuracy and preventing compressor short-cycling.
Motors and Fans
Our indoor and outdoor AC motors are designed for continuous operation in demanding environments. We provide shaded-pole and permanent split capacitor (PSC) motors for fan applications, with options for different speeds and voltages. Fan blades are available in various diameters and pitches to match airflow requirements.
We also supply defrost timers, thermostat guards and select switches that are commonly needed during maintenance or retrofit projects.
Installation and Maintenance Accessories
To support complete installations, we offer air conditioner brackets, flow deflectors, service bags, high-pressure washers, charging valves, capillary tubes and insulation tubes. These accessories help ensure proper mounting, airflow direction and system protection.
For service technicians, we provide charging valves and capillary tubes that are critical for refrigerant management. Insulation tubes prevent condensation and improve energy efficiency by reducing thermal loss along refrigerant lines.
Quality Assurance and Testing
We implement quality control throughout our production and sourcing processes. For capacitors, we use advanced testing equipment to monitor key parameters in real time. For sourced components, we work with established manufacturers and perform incoming inspections to verify specifications.
Our products are designed to meet international standards for safety and performance. We can provide documentation such as test reports and certificates upon request for specific projects.
Information We Use to Configure Your Solution
To prepare an accurate quotation and configuration, we need the following details about your project:
- Application type: window, split, central or commercial AC system.
- Brand and model of the original part (if replacing).
- Key specifications: capacity (BTU/HP), voltage, frequency, refrigerant type.
- Quantity and target delivery timeline.
- Any special packaging or marking requirements.
With this information, we can recommend the correct part numbers and ensure compatibility with your system.
