Product Overview
In business parks adding tenancies faster than their mains can serve, the simultaneous demand of the morning peak places heavy loads on the supply; the Hydro Multi-E 3 CRE 15-1 answers with three CRE 15-1 pumps operating in parallel. Specify part number 99614446 and the whole set lands tested, assembled and ready for pipework.
The system supports flow rates up to 1400 L/min. It can develop up to 21 metres of head for dependable pressure boosting. Because every pump carries its own frequency converter and the Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.
For installation, the booster is supplied pre-assembled with stainless steel manifolds, two 100 mm manifold connections, isolation valves, non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It is designed for 3 x 380-415 V power at 50 / 60 Hz with a rated current of 9.3 A, with IP54 motor protection and a 10 bar maximum system pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.
Its home ground covers hospitals, hotel plant rooms and aged-care complexes. The variable-speed system suits clean-water boosting duties with changing demand.
Features
- The stainless steel manifold assembly is supplied with two 100 mm manifold connections.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- At P2 each main pump is 1.5 kW, covering the duty without oversizing the frame.
- The system pairs three CRE 15-1 pumps in parallel duty, controlled as a single coordinated system.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- The set ships with an 24L precharged diaphragm tank for low-flow stability.
- Rated for 10 bar system pressure; motors carry IP54 protection.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a phone.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
