15kW Automatic Variable Frequency Drive Hvac Air Compressor VFD

KY900E Series Construction Air Compressor Dedicated Variable Frequency Drive

The frequency converter for building air compressors is an energy-saving control device designed specifically for the working conditions of the construction industry. It optimizes the operation of the air compressor through frequency conversion speed regulation technology to meet the gas demand in high load and complex environments of construction sites.

Technical Principles

The dedicated variable frequency drive for building air compressors is an energy-saving control device designed to meet the high load and complex working conditions of construction sites. Combining variable frequency speed regulation technology with the operating characteristics of air compressors, it achieves the following functions:

• Precise pressure control: Automatically adjust the motor speed through PID algorithm to maintain stable gas supply pressure (error ≤± 0.1bar).
• Energy saving and consumption reduction: Compared with traditional power frequency drive, the comprehensive energy saving rate reaches 20% -50%, and the energy consumption during no-load operation is reduced to 30% -40% of full load.
• Equipment protection: Built in 12 protection functions including overload, overvoltage, undervoltage, phase loss, grounding, etc., extend the motor life by 2-3 times.

Core Advantages

• Fast dynamic response: pressure fluctuation recovery time<50ms, meeting the instantaneous high load demand of construction sites.
• Soft start function: The starting current is ≤ 2 times the rated current, reducing the impact on the power grid.
  Waste heat recovery interface: Reserved RS485/CAN bus, supporting linkage with air compressor thermal energy recovery system.
• Multi machine linkage control: supports 1-to-N (such as 1 frequency converter driving 4 air compressors), optimizing energy allocation.

Application scenarios

• High rise building construction: Provide a stable air source for pneumatic tools such as anchor drills and breakers.
• Tunnel engineering: Used in conjunction with rock drills and wet sprayers to adapt to high-altitude environments above 3000 meters.
• Bridge construction: Provide air supply for sandblasting rust removal and pneumatic tensioning equipment, with pressure fluctuations of ≤± 0.05 bar.
