Smart compact water booster platform upgrades are at the heart of Ebara Corporation’s expanded “Fresher 3100NEO BN‑MG” water supply unit range, giving design engineers and contractors greater freedom when sizing booster systems for buildings and industrial facilities. The updated line‑up now includes 0.75 kW, 3.7 kW (65 mm port size), 5.5 kW and 7.5 kW models, enabling a more precise match between pump output, physical space and real site demand.
Smart compact water booster concept
The Fresher 3100NEO BN‑MG series is a packaged water supply unit engineered to provide stable pressure and flow in applications such as apartment blocks, commercial buildings, factories and other facilities where incoming or municipal pressure is insufficient. By integrating pumps, controls, valves and associated components on a compact skid, this smart compact water booster platform simplifies design and installation compared with fully bespoke systems assembled piece‑by‑piece on site.
Since its market introduction in 2019, the series has been positioned as a lightweight, space‑efficient option for crowded plant rooms and mechanical spaces where every square metre counts. In 2024, Ebara enhanced the platform with a motor terminal box‑less structure and an outdoor installation option, helping mechanical and electrical designers exploit rooftops or external plant areas when indoor space is limited.
New models and sizing flexibility
The latest expansion of the Fresher 3100NEO BN‑MG range comes in direct response to customer feedback from the Japanese market, where consultants and installers have been seeking finer output steps that track more closely with real‑world load profiles and equipment arrangements. On smaller systems, the new 0.75 kW model targets low‑rise residential blocks, compact commercial buildings and facilities with moderate demand variation, while the 3.7 kW unit with a 65 mm port size supports medium‑scale applications.
At the higher end, the 5.5 kW and 7.5 kW units are designed for larger buildings and demanding industrial utilities, delivering the heads and flows needed to maintain pressure right through to remote or elevated points of use. By expanding the line‑up across this 0.75–7.5 kW spectrum, the smart compact water booster platform helps prevent oversizing, which can otherwise increase capital cost, power consumption and lifecycle operating expenses.
Ebara stresses that aligning booster output with actual site requirements is critical in multi‑storey projects, where pressure profiles must be balanced carefully so that top floors receive sufficient supply without exposing lower floors to excessive pressure. The broader model range gives engineers more room to specify equipment that fits each building’s height, demand curve and piping layout, complementing detailed hydraulic calculations and digital design tools often used on complex schemes.
Controls, operation modes and protection
From a control standpoint, the Fresher 3100NEO BN‑MG units support both single‑alternating and parallel‑alternating operation, offered in BNAMG and BNBMG configurations to suit different redundancy philosophies and runtime‑balancing strategies. The control system incorporates functions to maintain an estimated terminal pressure while managing pump start frequency during low‑flow periods, reducing the risk of short‑cycling and extending equipment life.
The logic also moderates pressure restoration when power returns after an outage, helping to protect downstream piping, valves and fixtures from sudden surges that can cause leaks or nuisance failures. For projects where reliability and service continuity are essential, such as commercial towers, hospitals or industrial plants, these features allow the smart compact water booster platform to integrate cleanly with broader building management systems and protective schemes.
Installation, footprint and retrofit advantages
The expanded line‑up is available for three‑phase 200 V (50 Hz) and 200/220 V (60 Hz) power supplies, covering the 0.75–7.5 kW output range and a variety of suction conditions. Design options accommodate both suction‑lift and flooded‑suction configurations, giving specifiers flexibility where civil constraints or existing tanks dictate pump elevation relative to the water source.
Beyond pure performance, Ebara highlights the practical benefits of a compact, lightweight packaged design that can be manoeuvred through narrow access routes, stairwells and tight plant spaces with less reliance on heavy lifting equipment. For installation teams working under labour constraints or compressed timelines, fewer on‑site assembly steps and faster commissioning reduce project risk and can lower total installed cost, especially on retrofit and upgrade projects typical in mature building stock.
Energy efficiency, ESG and SDG alignment
The Fresher 3100NEO BN‑MG series is described by Ebara as part of a wider portfolio of energy‑saving and environmentally conscious pumping and water supply products. By allowing closer alignment between pump capacity and demand, and by using intelligent control strategies that avoid unnecessary starts and excessive pressures, the smart compact water booster platform supports lower electricity use over its lifecycle.
These characteristics tie into Ebara’s long‑term vision and medium‑term management plan, which place emphasis on ESG material issues and contributions to the UN Sustainable Development Goals, including clean water and sanitation, sustainable cities and communities, and climate action. As building owners and industrial operators face tighter efficiency regulations and decarbonisation expectations, such solutions help them modernise water infrastructure while managing operating expenditure.
Key takeaways for engineers and facility owners
With the expanded Fresher 3100NEO BN‑MG line‑up, Ebara is positioning its smart compact water booster platform as a versatile choice for projects ranging from compact building services installations to larger industrial utilities. The combination of refined sizing steps, integrated controls, install‑friendly footprints and efficiency‑focused design gives consulting engineers, contractors and facility managers more options when tailoring systems to each site’s specific needs.
As markets increasingly prioritise lifecycle efficiency, resilience and ESG performance, flexible packaged booster solutions are set to play a bigger role in new build and retrofit projects alike.
