Westec Tank & Equipment

What Westec Tank & Equipment does

Westec Tank & Equipment is a privately held, family-owned specialty fabricator of custom stainless steel wine tanks and winery equipment, headquartered in Healdsburg, California. The company designs, fabricates, and installs tanks ranging from 10-gallon portable units up to 350,000-gallon field-built fermentation and storage vessels, alongside integrated catwalks, micro-oxygenation systems, dimple cooling jackets, and complementary winery equipment such as sump carts, manways, and de-juicing screens. Its core manufacturing differentiator is a set of custom-built dimple jacket machines that produce 5-foot and 6-foot wide cooling panels not available from standard fabricators, enabling fewer seams, simpler plumbing, and more uniform glycol cooling on large tanks.

The company operates a dual-channel delivery model: shop-built tanks and components are fabricated at the Healdsburg facility (which holds California B, C60 welding, and C38 refrigeration contractor licenses), while field-built tanks of 60,000-250,000 gallons are constructed on-site at customer wineries using A-frames, cranes, and trained installation crews. Westec also provides engineering and layout services using 3D modeling software, along with retrofit and repair work for tanks made by any manufacturer. Customer engagement is direct and enterprise-style, working with winery owners, vintners, and architects from facility design through installation, and the customer base consists predominantly of Northern California wineries of varying scale, with adjacent work extending into craft distillery equipment.

Revenue is generated one-time per project on a quote basis with no public pricing, supplemented by ongoing retrofit and repair services. There are no disclosed funding rounds, no external institutional investors, and no public listing; ownership and management are concentrated in the Belli family and long-tenured personnel including Mark McDowell. The company has been operating continuously for over 30 years, holds OSHA Golden Gate safety recognition, and maintains a technology-integration partnership with StaVin for combined oxygen and oak management systems.
