Expanding its new line of SA-Series space heaters, Cambridge Engineering has added the SA350, capable of delivering 350,000 Btus per hour for commercial and industrial applications. The Cambridge SA-Series uses the same technology as the larger ultra high efficiency Cambridge S-Series but is sized for efficient heating and ventilation of smaller spaces. The SA-Series units offer the flexibility of being mounted through-wall, under roof or rooftop, potentially providing more usable interior space. As with other Cambridge heaters, the stainless-steel burners are supported with a five-year warranty with all other components warranted for two years.
