Is your company wasting this money?
Electricity black hole:
The fan/water pump operates at full load for a long time, and the proportion of no-load power consumption exceeds 40%!
For example, one 110kW water pump has an annual no-load power consumption of 110kW × 40% × 24h × 300 days=316800 kWh (calculated at 0.08 cent/kWh, resulting in an annual waste of 25340 dollar)!
Equipment wear and tear:
Frequent start stop cycles have reduced the lifespan of motor bearings and windings by over 50%, resulting in an annual maintenance cost exceeding 15000 dollar!
Production bottleneck:
Traditional speed regulation response is slow (5-10 seconds), unable to meet high-precision production requirements, resulting in an 8% increase in defect rate!
ZFeng frequency converter, designed specifically for industrial scenarios, achieves energy saving, cost reduction, and efficiency improvement in one step!
Significant energy-saving effect
Accurate load matching: The frequency converter dynamically matches the output power with the actual demand by adjusting the motor speed, avoiding energy waste caused by the "big horse pulling small car".
Case: A 110kW water pump in a certain factory used to consume 800000 kWh of electricity annually, but after installing a frequency converter, it saved 45% of energy and 360000 yuan in annual electricity bills (calculated at 0.8 yuan/kWh).
Soft start energy-saving: Smooth starting current is reduced to 1.2 times the rated current, reducing grid impact and no-load power consumption.
Square torque characteristic: The power of loads such as fans and pumps is proportional to the cube of the rotational speed, and a 10% reduction in rotational speed can save 27% energy.
Decrease in operation and maintenance costs
Reduce mechanical wear: Soft start and deceleration control reduce the impact of motors, bearings, and gears, extending equipment life by 2-3 times.
Data: After the transformation of the reaction kettle motor in a certain chemical plant, the bearing replacement cycle has been extended from 1 year to 4 years, and the annual maintenance cost has been reduced by 70%.
Reduced failure rate: overcurrent, overvoltage, and overheating protection mechanisms reduce the risk of motor burnout, resulting in a 90% decrease in failure rate.
Predictive maintenance: The IoT module monitors the motor status in real-time, alerts potential hazards in advance, and reduces unplanned downtime.
Production efficiency improvement
Fast speed response: Vector control technology achieves millisecond level response, meeting high-precision production requirements.
Case: After the transformation of a steel mill, the torque fluctuation was ≤ 3%, the rolling speed increased by 15%, and the annual output increased by 8%.
Process optimization: Closed loop control (such as PID) achieves precise adjustment of temperature, pressure and other parameters to improve product quality.
Flexible production: supports multi-stage speed, automatic start stop and other functions to adapt to different production scenarios.
Outstanding environmental benefits
Reduce carbon emissions: Energy conservation directly reduces fossil energy consumption. A certain cement plant saves 1.2 million yuan in electricity bills annually, corresponding to a reduction of 960 tons of CO ₂ emissions.
Reduce noise pollution: Smooth speed regulation of the frequency converter reduces mechanical vibration and reduces noise by 30-50dB.
Compliance with policy requirements: Assist enterprises in passing energy efficiency assessments and obtaining government energy-saving subsidies (up to 40% of project investment).
