Aalberts is sharpening its pitch to residential developers with the Pegler ResiFlow prefabricated utility array, a factory-built riser solution designed to speed up and standardize installations in multi-occupancy buildings. The system bundles hot and cold water, heating and metering components into a single pre-assembled unit that arrives on site ready to connect, shifting labor off the construction site and into controlled production.

How Pegler ResiFlow changes multi-occupancy riser installs

ResiFlow is marketed under Aalberts integrated piping systems' Pegler brand in the UK and targets high-density residential projects such as apartment blocks and student housing, where dozens or even hundreds of identical utility cupboards must be built to tight schedules. Instead of assembling valves, manifolds and meters piece by piece in each riser, contractors can specify a ResiFlow array that is built to project requirements, pressure-tested at the factory and delivered as a single module per dwelling. According to a case study from a major London development in White City, the prefabricated arrays significantly reduced on-site assembly time and simplified coordination between trades, as each cupboard was installed in a repeatable, standardized process. A construction industry report on the White City project details how ResiFlow modules streamlined the multi-occupancy installation.

From a technical standpoint, ResiFlow arrays are built around Pegler's own valves, fittings and manifolds, combined into a steel-framed cabinet that can house isolation valves, balancing valves, hot and cold distribution manifolds and metering points within a compact footprint. The manufacturer emphasizes that all pipework and joints inside the unit are fabricated under factory conditions, which allows for consistent joint quality and pressure testing before delivery to site. For developers and main contractors, that reduces the amount of hot works and assembly time in finished corridors, while giving building-control inspectors a clearly defined, repeatable layout in every riser cupboard. Because the arrays are custom-configured per project, they can also be designed with maintenance access in mind, grouping shut-off valves and meters where they remain accessible once the cabinet is boxed in.

Aalberts positions ResiFlow as part of its broader move toward modular, off-site fabricated piping solutions, alongside its press-fitting and connection technologies. The company has highlighted the role of engineered prefab units in reducing waste, limiting on-site welding and minimizing labor demands in tight construction markets such as the UK. In its corporate materials, Aalberts stresses that integrated piping systems are a core growth platform within the group, serving commercial and residential buildings as well as data centers and industrial facilities. The integrated piping systems business segment overview on Aalberts' website describes prefabricated arrays like ResiFlow as part of its engineered solutions portfolio.

Strategically, products like Pegler ResiFlow allow Aalberts to capture more value per project than individual valves or fittings, since the prefabricated unit combines multiple components with engineering and assembly services. That fits with the firm's emphasis on "mission-critical technologies" where it can be a partner to engineers and contractors rather than a pure parts supplier. The White City reference project shows how such systems can win specification on large developments, creating repeat business as developers roll out similar designs across multiple sites. For now, ResiFlow is primarily visible in the UK residential market under the Pegler brand, but the concept aligns with a wider trend toward modular building services in Europe.

Aalberts is headquartered in the Netherlands and is publicly listed in Amsterdam, where its shares trade under the ticker AALB. According to recent Euronext data, Aalberts shares changed hands on Euronext Amsterdam in euros, reflecting investor expectations for its key business segments including integrated piping systems, surface technologies and advanced mechatronics.
