1 DX330 L/M/V SERIES Universal Intelligent Controller for Screw Air Compressor Please experience DOTECH s technology based on simplicity, multi-function and safety!! Easier Faster Safer DOTECH, INC

2 C M K DX330 DX330 efficiently controls screw type air compressor based on microprocessor, gives users an alarm against trip by checking the status of the machine in advance and offers users the information for maintenance and let them treat it quickly and easily. Also, it is the cutting-edge electronic controller mounted with VSD (Variable Speed Drive) based on PID control system, which can help users to save more than maximum 30% of the energy costs. - Reducing the energy costs using VSD (Variable Speed Drive) Using inverter, the revolution of motor can be freely set up by either a microprocessor or users, so it is possible to start and stop flexibly. Also, it has users reduce energy cost by getting efficient and economic operation cost comparing with existing air compressor with other controllers. - Applying for the large size graphic LCD displayed by multi-language (Korean, English, Chinese and Japanese, etc.) - Easy analyzing for the trouble by storing up to maximum 160 numbers of trip alarm history (Black box function) - Notifying the information and expected time for PM (preventative & maintenance) and exchanging RSP (recommended spare parts) schedule - Automatic recovering from CPU down caused by noise - Various analogue output function (Inverter speed control, discharged pressure & air temperature transmission, etc.) - Establishing the most optimized system embedding high-function and high-efficiency in spite of monolithic small size - Providing perfect interface with upper systems by mounting RS485 communication, MODBUS RTU international standard protocol INVERTER OUTPUT 45.0 Hz COMPUTER TOUCH SCREEN INVERTER : 20 지열출구저온 02 DX : 20 지열출구저온 02 AIR COMPRESSOR
