What Elbi does

Elbi S.p.A. is a privately held Italian industrial company headquartered in Limena (Padua province), Italy, specializing in pressure equipment for hot water storage and heating systems. Its core product lines include autoclaves (pressure tanks), membrane expansion vessels, and air cushion autoclaves, sold under the Elbi trade name to industrial and professional customers via a quote-based B2B model.

The company supports its hardware offering with three web-based engineering sizing calculators — for autoclaves (UNI 9182), membrane expansion vessels (Raccolta R 2009), and air cushion autoclaves (UNI 9182) — that allow engineers and installers to compute required vessel volumes from project parameters such as pump flow rate, pressure settings, pre-charge pressure, and system volume. These tools act as a top-of-funnel demand generation asset and embed Elbi into the specification workflow.

Elbi distributes through a regional sales network of authorized resellers and a dedicated B2B reserved portal at b2b.elbi.it for registered business customers, supported by a corporate quote request flow on the main website. The company is privately held, has a registered share capital of €5,200,000, operates primarily in Italy within the broader European market, and discloses no public revenue, headcount, funding, or M&A activity in the available source data.
