Wedholms AB

What Wedholms AB does

Wedholms AB is a privately held Swedish industrial company founded in 1879 in Nyköping by Carl August Wedholm, specializing in the design and manufacture of milk cooling tanks, CO2-based refrigeration systems, and related accessories for dairy farms. The company's core technology is direct expansion cooling using carbon dioxide (CO2) as a natural refrigerant with a Global Warming Potential (GWP) of 1, delivered through a product portfolio spanning horizontal tanks, silo tanks, open tanks (from 330L up to 40,000L capacity), cooling units, the Genovus/Argos control systems, and a Milk Tank Manager software module. The portfolio is engineered to integrate with all major milking systems, including robotic platforms, and includes heat recovery functionality.

The company's business model is primarily B2B capital equipment sales, complemented by aftermarket service and spare parts. Distribution combines a global network of authorized dealers and Lely Centers — including Eurotanks (Poland, Lithuania, Latvia) and Kylmakarki (Finland) — with regional sales managers covering Sweden, Norway, Finland, Estonia, Poland, Lithuania, Latvia, and Export markets, plus a direct e-commerce webshop for spare parts. A 2006 exclusive OEM relationship with Lely makes Wedholms the sole manufacturer of Lely Nautilus milk cooling tanks designed to integrate with Lely Astronaut milking robots. A September 2024 partnership with Sigma Technology Tech House is intended to develop next-generation IoT-enabled control systems, signaling a strategic move into smart connected products. Revenue is not publicly disclosed; the company operates multiple units covering manufacturing, engineering, sales, and service, and is positioned to benefit from the EU F-Gas Regulation (EU/2024/573) banning high-GWP refrigerants in milk cooling from January 2025.

• Mueller Industries / Paul Mueller Company: Paul Mueller Company manufactures milk cooling tanks and dairy processing equipment, including bulk tanks for on-farm use. It is a direct peer to Wedholms in the milk cooling tank category, primarily in the Americas.
• DeLaval: DeLaval is a global leader in dairy farming solutions, including milk cooling tanks and integrated milking systems. It is the most directly comparable peer to Wedholms, competing head-to-head on bulk milk cooling equipment and farm automation.
• JOZ: JOZ is a Dutch manufacturer of dairy farm equipment including manure robots and stable equipment, with adjacent exposure to on-farm systems. Less direct overlap on cooling specifically, but operates in the same farm-equipment category and customer base.

Others

• Lely: Lely is Wedholms' strategic partner and exclusive customer for Nautilus milk cooling tanks, but also a broader dairy farm automation provider (Astronaut milking robots). Listed as peer because a change in their sourcing or competitive overlap would directly affect Wedholms' business.

Broad incumbents

• GEA Group: GEA is a large industrial equipment manufacturer with a dedicated dairy farming and milk cooling/tank business, alongside much broader food processing and separation technology. Competes with Wedholms on farm-side milk cooling and storage equipment but operates at much larger scale across multiple verticals.

Emerging players

• Fabdec: Fabdec manufactures milk cooling and heat recovery solutions for dairy farms in the UK and Ireland, with emerging focus on low-GWP and energy-efficient systems. Comparable as a smaller specialist peer in the milk cooling and heat recovery niche.
