ICHIKAWA Product Lineup

"HVAC" achieves miniaturization by eliminating the need for peripheral devices through harmonic suppression. Additionally, it allows for a reduction in generator capacity, leading to lower initial investment, and contributes to energy savings through the high-efficiency operation of PM motors. Due to its simple design, wiring labor can be significantly reduced, complicated calculations are unnecessary, and application procedures can be easily completed. [Features] - Miniaturization of control panels - Miniaturization of power supply equipment capacity due to high power factor - Miniaturization of emergency generators due to power supply harmonic suppression - Energy savings - Simple design *For more details, please refer to the PDF materials or feel free to contact us.*

The "V-CONT Series" is an inverter air conditioning power panel that provides transport energy data through digital communication. With the AHU controllers from Azbil Corporation and upper-level PCs, data from different manufacturers and models of inverters used in transport machinery can be easily utilized. Furthermore, with the digital operation panel (VOP), operation and maintenance can be standardized even if the manufacturers and models of the inverters differ. 【Features】 ■ Standardization of air conditioning power panels and adoption of digital communication ■ Miniaturization and reduced wiring of instrumentation power panels ■ Provision of transport energy data through digital communication ■ Monitoring and management of energy consumption (CO2 emissions) ■ Streamlining of on-site operations through standardization of operation and maintenance *For more details, please refer to the PDF materials or feel free to contact us.

The "VPM Series" is a motor that rotates in complete proportion to the frequency of the inverter. Due to its high efficiency, it is widely adopted for energy-saving applications. Since it has permanent magnets, there is no secondary current flowing in the rotor, which means there are no losses in the rotor. Additionally, because the dimensions are the same as standard motors, it is easy to replace existing motors. 【Features】 ■ Energy-saving ■ No losses in the rotor ■ Usable in both axial and radial orientations according to fan applications ■ Comprehensive measures against creeping ■ Easy replacement with existing motors *For more details, please download the PDF or feel free to contact us.
