Baltimore Aircoil got its start back in 1938, when John Engalitcheff Jr. built the first blow-through evaporative condenser in his garage. He even pawned his wife’s wedding ring to get the business going. Over the decades, it grew from that one invention into a full-blown global company with plants in multiple countries, lots of patents (especially in evaporative cooling), and a reputation for being a pioneer. They were early movers in modular cooling equipment, corrosion protection, hybrid cooling, and thermal storage.

In time, BAC added cooling towers, evaporative condensers, closed-circuit cooling towers, dry coolers, hybrid/adiabatic chillers, immersion cooling, and thermal storage units to their portfolio. Their tech tends to focus on efficiency, water/energy savings, durability, and adaptable designs for heavy-duty industrial & refrigeration / HVAC / process cooling uses. They’ve also built up a lot of R&D strength, pushing steady innovation in materials, fan systems, fill kits, and sustainable performance.

BAC’s cooling towers, evaporative condensers, and dry coolers are built for long service and tough conditions: dealing with water, heat loads, corrosion, and continuous cycling. For many plants (processing, plastics, food, data centers, etc.), cooling systems are mission-critical: keeping processes stable, avoiding downtime or damage, and meeting environmental/efficiency standards.
