DC Piston Oil-free Compressor
Leynow · DC Oil-free Compression Technology
Vehicles, energy storage cabinets, and outdoor equipment are mostly DC-powered. Using AC compressors requires additional inverters, increasing loss, volume, and cost.
Fixed-frequency solutions start and stop frequently, with obvious noise and vibration, affecting the experience in scenarios such as nighttime rest and medical silence.
Wrong selection of voltage platform and displacement leads to slow cooling and large temperature fluctuations, making it difficult to stably maintain the set range.
Controllers, liquid receivers, filter driers, etc., need to be purchased from multiple suppliers, parameters do not match, and the integration cycle is lengthened.
Supports multiple DC voltage platforms such as 12V/24V/48V/72V, wide voltage range design, reducing inverter links, convenient for direct matching in scenarios such as vehicle-mounted, RV, and energy storage cabinets.
Brushless DC motor with inverter drive, adjustable speed; operates at reduced speed under low load, reducing frequent start/stop, helping to control overall power consumption and operating noise.
Small, medium, and large displacement low-temperature series are available, corresponding to different box volumes and target temperatures, covering scenarios such as vehicle-mounted refrigeration, parking air conditioning, and frozen storage.
Optimized dynamic balance and vibration damping structure, compact complete machine; horizontal and vertical installation orientations are available, convenient for embedding in small equipment and narrow spaces.
Fully enclosed compressor structure, closed operation of the refrigerant circuit, reducing leak points; simple structure, suitable for equipment requiring long-term continuous operation.
Can be matched with drivers, speed control, liquid receivers, filter driers, and other components; selection calculation based on box volume, ambient temperature, target temperature, and cooling time.

The Leynow DC compressor is driven by a brushless DC motor. The driver receives the temperature sensor signal and automatically adjusts the compressor speed according to the set temperature and actual temperature difference.
The refrigerant completes the cycle through compression, condensation, throttling, and evaporation, transferring heat from the box or cabin to the external environment to achieve cooling and constant temperature control.
Compared with fixed-frequency solutions, inverter speed regulation allows the compressor to operate at reduced speed under low load, reducing frequent start/stop, helping to reduce power consumption and noise; the fully enclosed structure facilitates equipment integration and long-term operation.

Usage Limitations: Compressors must be matched with the refrigerant model, refrigeration oil, and system piping; the system must be strictly evacuated and moisture content controlled; do not operate for a long time beyond the specified voltage range and working conditions; the condensing side must ensure heat dissipation conditions to avoid high-temperature and high-pressure protection shutdown.
Selection Recommendations: Calculate the required cooling capacity according to box volume, target temperature, ambient temperature, and cooling time; it is recommended to reserve a 15%-20% performance margin; for low-temperature working conditions, select low-temperature compressors and suitable refrigerants; confirm the matching of the voltage platform, driver, and control system before batch integration.
DC compressors are directly driven by DC power, suitable for scenarios with only DC power such as vehicles, energy storage cabinets, and outdoor equipment, reducing inverter links; with a driver, speed regulation can be achieved, operating at reduced speed under low load, helping to control power consumption and noise. AC compressors are more suitable for fixed locations with stable mains power.
Small-volume vehicle-mounted refrigerators and portable coolers mostly use 12V/24V; parking air conditioners, RV air conditioners, and larger transport boxes mostly use 48V/72V; for large displacement low-temperature requirements, the wide voltage low-temperature series can be selected. During selection, it is necessary to simultaneously confirm the power platform, box volume, target temperature, and cooling time, and it is recommended to reserve a 15%-20% margin.
Under the premise of stable voltage, good condensing heat dissipation, and correct refrigerant charge, Leynow DC compressors can support long-term continuous operation; it is recommended to confirm operating parameters according to working conditions and ensure ventilation and heat dissipation conditions on the condensing side.
