Product Overview
In hotels whose kitchen, laundry and bath peak collide at six in the morning, the simultaneous demand of the morning peak places heavy loads on the supply; the Hydro Multi-E 3 CRE 15-4 answers with three CRE 15-4 pumps operating in parallel. Part number 99614455 provides the complete tested package in a single order line.
The system supports flow rates up to 1240 L/min. It can develop up to 79 metres of head for dependable pressure boosting. There is no separate central controller to purchase: Multi-Master control resides within the pumps, either unit can assume the controlling role, and a fault is handed over cleanly without interrupting supply.
The three-pump package arrives as one base-mounted assembly with stainless steel manifolds, two 100 mm manifold connections, valves, sensors and a pressure gauge, plus a 24L diaphragm tank. Electrical supply is 3 x 380-415 V at 50 / 60 Hz with a rated current of 24.3 A. The motors have IP54 protection and the system is rated to 10 bar maximum pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.
Typical duty sits with aged-care complexes, mixed-use commercial buildings and high-rise apartments. It is designed for clean-water pressure boosting where demand varies through the day.
Features
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Three Grundfos CRE 15-4 vertical multistage pumps run in parallel on one common base frame.
- The system protects its pumps against dry running if the incoming supply is lost.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- 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.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Each main pump is rated 4 kW (P2), so per-pump draw scales down as speed follows demand.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- Stainless steel manifolds provide two 100 mm manifold connections ready for pipework.
- The set ships with an 24L precharged diaphragm tank for low-flow stability.
