This webinar with Cambridge Air Solutions discusses the benefits and applications of their S Series direct-fired heaters, specifically designed for high-bay, open spaces such as warehouses, manufacturing facilities, and distribution centers. The main focus is on high-temperature heating ventilation (HTV), a term used to describe systems that provide 100% outside air with a temperature rise of more than 140°F and a discharge temperature exceeding 150°F. These systems are fully modulating, allowing them to meet both space heating and ventilation needs. 

They emphasize that HTV systems, especially Cambridge’s S Series, offer three key advantages over traditional unit heaters: lower installation costs, significant energy savings, and improved ventilation. The S Series units can replace multiple unit heaters in a single package, reducing the need for electrical connections, gas piping, and flue gas venting, which leads to lower overall installation costs. Additionally, their high-temperature discharge and direct-fired design make them up to 60% more energy-efficient than competing technologies, particularly in retrofit applications. This efficiency stems from both the direct-fired system’s combustion efficiency and the elimination of stratification, a common issue in high-ceilinged spaces. 

Stratification, where warm air rises and accumulates near the ceiling, is mitigated by the high-velocity discharge of the S Series heaters. These units discharge air at speeds of 1,500 to 2,000 feet per minute at a 45-degree angle, ensuring even air distribution throughout the space. This design induces air movement across the floor and back up to the ceiling, creating a more uniform temperature throughout the building, reducing heat loss to the roof, and improving occupant comfort. 

Another significant benefit of the S Series is its ability to provide 100% outside air for ventilation. Many buildings rely on natural infiltration for ventilation, but mechanical ventilation systems like those in the S Series can offer more consistent, filtered air, improving indoor air quality. This feature is especially important in large, leaky buildings that may otherwise lack proper ventilation. 

The webinar also addresses design considerations for HTV systems, such as unit placement and air load management. Cambridge Air Solutions assists with system layout and design to ensure optimal performance, and their S Series units are flexible in terms of installation options, including rooftop, through-wall, and vertical setups. Available in a range of sizes, from 250,000 BTU to 3.2 million BTU, these units can be tailored to a variety of high-bay applications. 

Cambridge’s S Series HTV units provide an efficient and cost-effective solution for heating and ventilating large, open spaces. Their ability to reduce installation costs, improve energy efficiency, and mitigate stratification makes them a valuable choice for facilities looking to enhance heating performance while maintaining good indoor air quality.
