Accelerated circulation in domestic hot water loops. Instant hot water on demand. Collective housing Offices Local authorities Industries Hospitals Hotels, etc. Qm /h BENEFITS Certified Reliable components Motor compartment insulated by a mechanical seal. Motor equipped with an integral (and automatic in -M) ipsothermal sensor Compact size. Easy to install - no alignment problems. Harmless materials in contact with water - maintains water quality. Very quiet operation as all rotating parts and components in contact with water are integrated into the motor cartridge. Choice of operating speeds (dual voltage, three-speed motor in three-phase). Automatic venting. Maintenance-free V -speed selector~ V (accessory) N.T. No -/ENG - Ed. /-
