RBM

What RBM does

RBM SPA is an Italian designer and manufacturer of plumbing and heating components and systems, organized around five divisions: hydrothermal distribution, energy efficiency, climate comfort, air treatment, and service. Founded in 1953 by the Bossini family in Lumezzane and now headquartered in Nave (Brescia), the company operates four vertically integrated production plants in the Brescia area — two for brass components and two for plastic processing — supported by the 2,500 square meter RBM IBOX facility, which houses R&D (RBM I-LAB), laboratory and cyclic testing, training, and showroom functions. Its catalog spans 646 products, including patented magnetic sludge remover filters (MG1, MG2, MP1, MP2), hydraulic separators and mixing units, the Kilma Futura dry radiant panel, Zerofrost antifreeze valves, Stop Leak water detection systems, AIRFLAT and AIRFRESH mechanical ventilation with heat recovery, and chemical water-treatment additives, sold under the ITS, KILMA, and MORE Solutions sub-brands.

RBM monetizes primarily through B2B hardware sales to installers, wholesalers/distributors, construction companies, engineering and design firms, and OEM/private-label partners, with quote-based pricing and an aftermarket service and spare-parts stream. Distribution combines five wholly-owned international branches (France, Benelux, Australia, China) plus representative and agent coverage in Romania and Japan, with independent wholesalers reaching long-tail installers; go-to-market is reinforced by a BIM Objects specification portal, trade-show participation (e.g., ISH Frankfurt), and dedicated agent resources. The company is privately held under GLBS S.r.l., holds ISO 9001, EcoVadis Silver (72/100, 2024), and UNI/PdR 125:2022 certifications, and reports no public funding rounds or revenue figures.
