Energy-saving & Inverter: Optimally controls with inverter, and high efficient Permanent magnetic motor (TEFC) which has low heat loss characteristics and excellent environment resistance, reduces power consumption.
High quality stainless: Long life and clean due to adopting high quality stainless steel for major parts. because of its toughness, stable water supply is available for long term.
Low operation sound & Light weight design: Reduced operation noise of 5dB in maximum and mass of 38%, compare to conventional model, brings it installable in anywhere.
Constant discharge pressure: VFD keeps discharged pressure according to the water volume (Constant estimated terminal pressure water supply is also available in alternate & alternate parallel operation models)
Lengthened accumulator lifetime.
New developed small flow sensor (with temperature protective function)
Noise & harmonic suppression: Equipped noise filter and reactor as standard suppress noise and harmonic .
Soft start: VFD reduces starting current
Common use in 50/60 Hz
Certificated products by Japan Water Works Association is available in 150W model.
