ACI DLT Series Air Compressors Dedicated Energy-Saving CabinetThe dedicated energy-saving cabinet for air compressors is an
energy-saving control device designed for air compressor systems.
By optimizing motor operation and gas supply pressure control, it
significantly reduces the electrical energy consumption of air
compressors I. Working Principle
Air compressor motors operate in alternating "loaded" and
"unloaded" states. When the air pressure reaches the upper limit,
the motor enters an unloaded state, wasting electricity. The
energy-saving cabinet uses a pressure sensor to monitor air
pressure in real time, transmitting data to a central processing
unit (CPU). The CPU compares the set value with the real-time value
and sends instructions to the frequency converter to adjust the
motor speed, stabilizing the air supply pressure within the target
range and eliminating energy waste during unloaded operation. II. Technical Features Intelligent Constant Pressure Control
Transforms upper/lower pressure limit control into constant
pressure control, ensuring output power precisely matches demand.
This reduces high-energy losses in overpressure zones and avoids
inefficient unloaded or idling states, achieving energy savings of
10%–30%. Improved Power Factor
Raises the power factor from 0.7–0.8 to over 0.96, reducing
reactive current and line losses, and enhancing grid quality and
power supply efficiency. This effectively increases the capacity of
the power supply equipment. Soft Start and Protection
Enables smooth, impact-free starting, reducing stress on the motor
and grid, extending motor lifespan, and providing multiple
protections (overcurrent, overload, overvoltage, undervoltage,
etc.). Noise Reduction and Environmental Improvement
Reduces equipment noise by approximately 10 dB, ensuring smoother
operation and improving the working environment. Bypass/Energy-Saving Switching Function
Facilitates switching between energy-saving and bypass modes,
ensuring production stability.
III. Application Benefits Significant Energy Savings
A case study shows that a 250 kW air compressor equipped with the
cabinet saved 52 kWh per hour, reducing annual electricity costs by
approximately 360,000 yuan. For a factory with four 200 kW–280 kW
compressors, annual savings exceeded 1 million yuan, totaling over
10 million yuan in 10 years. Optimized Air Supply Quality
The closed-loop control system maintains constant pressure and
on-demand air supply, preventing damage to pipelines caused by
excessive pressure and reducing maintenance costs. Extended Equipment Lifespan
Soft starting and intelligent control reduce wear and tear,
prolonging the service life of air compressors and related
components.
IV. Product Advantages High Intelligence
Digital control ensures ease of operation, with RS-485
communication interfaces and standard protocols supporting
equipment upgrades and remote control. Simple Installation and Maintenance
Fewer peripheral components and plug-and-play terminals simplify
installation and maintenance. Ergonomic design enhances operational
comfort. Wide Applicability
Suitable for industries such as textiles, papermaking, machinery,
petrochemicals, power, cement, and food processing, as well as
public venues like shopping malls, hospitals, and schools.
