MULTISTACK BAC LLC

Multistack BAC LLC specializes in the design, integration, and delivery of precision thermal management systems and facility support services for mission-critical government operations. Their core technical expertise lies in the manufacturing of custom heat exchangers and fluid cooling packages, including plate heat exchangers rated for high thermal loads such as 16 kW and 130 kW systems handling flow rates up to 50 GPM. These systems are engineered for reliable operation in demanding environments, with precise control over process fluid temperatures and thermal transfer efficiency. The company also delivers facilities support services, including building mechanical equipment (BME) maintenance for critical infrastructure like elevators, demonstrating an ability to operate across both high-precision manufacturing and operational sustainment domains. Their unique value stems from dual proficiency in engineered thermal systems and facility lifecycle support, enabling end-to-end solutions for complex government installations. Multistack BAC LLC has established a consistent presence with the National Aeronautics and Space Administration, providing specialized thermal control hardware for spacecraft and ground-based test systems. Their work for the Department of State focuses on maintaining essential building systems, indicating a capacity to support both high-tech R&D environments and diplomatic infrastructure. The contractor demonstrates a pattern of delivering mission-critical hardware and maintenance services to agencies requiring rigorous reliability and compliance with operational standards. The company’s primary industry focus is in the manufacturing of other measuring and controlling devices, particularly thermal control equipment, alongside facilities support services. This positions them as a niche provider in the defense and aerospace supply chain, serving applications where thermal regulation directly impacts system performance and safety. Multistack BAC LLC is a small business structured as a 2L entity, headquartered in Willoughby, Ohio. While currently holding no formal government certifications, its operational footprint is centered on federal contract execution with a focus on technical precision and responsive service delivery within the U.S. government market.
