Hitachi Industrial Equipment Systems Direct Water Ace
Hitachi Industrial Equipment Systems
Approximately 74% smaller and about 12% more energy-efficient compared to conventional models, this direct water supply unit is suitable for installation in tight spaces.
Features - Prevention of Red Water The water connection parts of the pump unit are made of corrosion-resistant stainless steel and copper alloys, paying attention to the prevention of red water. - Compact and Lightweight By adopting a high-efficiency magnetic motor and a new piping method, we have achieved miniaturization (approximately 74% of the volume of conventional models) and weight reduction (approximately 77% of the mass of conventional models). It is suitable for narrow spaces such as building side walls, under eaves, and stairwells. - Enhanced Backup Function With the installation of a backup microcontroller, even if a failure occurs in the control system for any reason, one of the pumps will operate in backup mode, allowing continuous operation. In the event of a pressure sensor anomaly, it switches to motor load current control, maintaining constant discharge pressure control without stopping the pump. - No Vibration Isolation Frame Required Vibration-damping rubber is used at the pump mounting part inside the unit, so a vibration isolation frame is not necessary. (For piping connection parts, flexible piping is used.) For more details, please contact us.
