What PRO Engineering/Manufacturing does

PRO Engineering/Manufacturing Inc. is a privately held, family-owned industrial equipment manufacturer founded in 1977 in Milwaukee, Wisconsin by brothers Ed and Dave Michalski. The company specializes exclusively in pasteurization equipment for the beverage industry, producing tunnel pasteurizers (PRO/Line Series 4, 5, 7.5, 10 and Slim/Line), batch pasteurizers (Single Temp and Triple Temp variants), tunnel coolers, tunnel warmers, pouch coolers, the PRO/Float Transfer mechanism, and the PM-4 Pasteurization Monitor. All equipment is fabricated from 304 stainless steel and incorporates proprietary components including a Dynamic Transfer Mechanism mandated by one of the world's largest brewers and proprietary clog-resistant spray nozzle designs developed over four decades.

The company generates revenue through one-time capital-equipment sales of customized, quote-priced pasteurization systems, supplemented by a refurbishment/re-engineering service line for competitor pasteurizers and a trade-in program. Go-to-market is direct sales-led via a small team of dedicated account managers and in-house design engineers, serving over 100 beverage producers across the USA and expanding into four Canadian metropolitan markets (Toronto, Vancouver, Montreal, Calgary). Named customers span global enterprise beverage companies (Coca-Cola, Molson Coors, Miller Brewing) down through mid-market and craft brewers (Wisconsin Brewing Company, Darwin Brewing). Pricing is not publicly disclosed; entry-level turnkey batch systems start at approximately $25,000 for small-batch producers, while industrial tunnel pasteurizers are higher-ticket custom-engineered units.

The business model is asset-heavy industrial manufacturing with no recurring software or service revenue, no API or digital product surface, no external institutional investment, and no disclosed funding rounds. Strategic differentiation rests on accumulated pasteurization engineering expertise, proprietary mechanical innovations, the ability to service and refurbish competitor equipment (creating multi-decade customer relationships), and — as of July 2025 — a partnership with McIver Engineering & Controls for automated control panels that has enabled a new sub-$25K turnkey product tier targeting startup breweries and R&D labs.

Revenue model

1. Equipment Sales: Sale of tunnel pasteurizers, batch pasteurizers, tunnel coolers, tunnel warmers, and pouch coolers. Equipment is customized to customer specifications and includes various sizes from compact/small footprint to large industrial units.
2. Re-Engineering and Refurbishment: Repair and refurbishment of existing pasteurizers. Often more economical than full replacement as it avoids production downtime for equipment removal and installation.
3. Trade-In Program: Trade-in program for customers' current pasteurizers. PRO applies the trade-in value toward new pasteurizer purchases.
4. Service and Support: Ongoing service support including installation and commissioning of equipment. Account managers available post-sale for support.

Products and services

• PRO/Line Series 4 Pasteurizers Compact tunnel pasteurizer with a 4 ft wide by 24 ft long through-conveyor, designed for facilities with limited footprint that need pasteurization equipment fitting their space constraints. Targeted at smaller beverage producers that require tunnel-style continuous pasteurization but lack space for larger units.
• PRO/Line Series 5, 7.5, and 10 Pasteurizers Large tunnel pasteurizer series (Series 5, 7.5, and 10) positioned as the most economical large pasteurizers on the market. Designed for high-volume beer and beverage producers requiring cost-effective continuous pasteurization with high throughput.
• Slim/Line Tunnel Pasteurizers Extendable slim-design tunnel pasteurizers for facilities that cannot accommodate large pasteurizers. Offers scalable pasteurization with a compact footprint, suited to breweries with tight production floors.
• Single Temp Batch Pasteurizers Entry-level batch pasteurizers offering compact size and an accessible price point. Suitable for small-batch producers and exploratory projects requiring pasteurization. PRO-pioneered spray batch pasteurizer design.
• Triple Temp Batch Pasteurizers Batch pasteurizers that simulate multiple tunnel pasteurization processes in a compact unit. Features multi-stage heating, holding, and cooling phases for complex beverage formulations.
• Tunnel Coolers Cooling systems for packaged beverages following pasteurization, offering maximum performance with energy savings through efficient cooling zones. 304 stainless steel construction with PRO spray nozzle designs.
• Tunnel Warmers Warmers using minimum sump water volume, evaporative cooling, and thermal balancing to eliminate overheating issues in packaging lines. Features proprietary spray nozzles, 304 stainless steel construction, and plate-type heat exchangers.
• Pouch Coolers Cooling equipment designed for pouch-style beverage packaging, providing temperature control for flexible container formats such as pouches.
• PRO/Float Transfer Plates Floating transfer plates that transfer containers from ninety-degree in-feed conveyors to tunnel pasteurizer conveyors and from pasteurizer conveyors to ninety-degree discharge conveyors. 100% effective in eliminating dead zones where bottles/cans would remain outside transfer areas.
• Re-Engineering and Refurbishment Services Repair and refurbishment services for existing pasteurizers, including both PRO and competitor equipment. Often more economical than full replacement because it avoids production downtime associated with equipment removal and installation. Built on decades of experience refurbishing large pasteurizers.

Direct peers

• SPX FLOW: SPX FLOW designs and manufactures fluid handling and thermal processing equipment, including pasteurization and heat-exchange systems via its APV brand. APV plate heat exchangers and pasteurizer skids are widely used in brewery and dairy lines, making SPX FLOW one of the closest direct competitors in pasteurization technology.
• KHS GmbH: KHS is a leading German manufacturer of beverage packaging and filling line equipment, including tunnel pasteurizers for breweries and soft drink producers. Its full-line portfolio of filling, labeling, conveying and pasteurization systems is the most directly comparable competitor to PRO's tunnel pasteurizer offering for craft through large-scale brewers.

Broad incumbents

• Alfa Laval: Alfa Laval is a Swedish industrial group specializing in heat transfer, separation and fluid handling — including plate heat exchangers widely used for HTST pasteurization in breweries and beverage plants. Its products overlap with the thermal-processing technology at the core of PRO's pasteurizers.
• GEA Group: GEA is a major German supplier of food processing machinery, including pasteurization, separation and homogenization equipment for breweries, dairies and beverage producers. It competes with PRO across beverage thermal processing at multiple scales as part of a broader process-equipment portfolio.
• Tetra Pak: Tetra Pak is a global food and beverage processing giant offering heat treatment, pasteurization and packaging lines across dairy, juice, and beverage categories. It competes with PRO primarily at the high-volume, integrated-line end of the beverage pasteurization market.
• JBT Corporation: JBT is a US-based food processing and sterilization equipment supplier that inherited Stork's beverage and in-container sterilization capabilities. It offers tunnel pasteurizers and aseptic systems that compete with PRO's portfolio in high-throughput beverage applications.

Others

• Strahman Group: Strahman supplies specialty process equipment including valves, sampling systems and wash-down components used in beverage and brewing process lines. It is comparable as an adjacent process-equipment vendor to the same brewer and beverage producer customers PRO serves.
• Pneumatic Scale Angelus (Barry-Wehmiller): Pneumatic Scale Angelus, a Barry-Wehmiller Packaging Solutions brand, supplies filling, capping and end-of-line equipment to breweries and beverage producers. While not a head-to-head pasteurizer competitor, it is a comparable end-of-line integration vendor often named alongside PRO in brewer packaging-line projects.
