In Fairmont, WV, a manufacturer with a 160,000 ft2 building faced a challenge. They were using direct-fired-recirculation units to heat their facility, but this resulted in uneven temperatures, high operating costs, cold dock areas, and maintenance headaches. They knew they needed a solution that would not only reduce their energy consumption and carbon emissions but also save on annual operational costs. That's when they decided to turn to the Cambridge S-Series.

There are two main non-recirculating direct gas-fired heater designs for commercial and industrial applications and those are blow-through and draw-through. The main difference in these two systems is the location of the blower relative to the burner. While a simple difference, blow-through units provide multiple benefits for large industrial space heating driven applications.

We, at Cambridge are frequently involved with heating “spec” buildings. You know how it goes: a developer puts up the shell, pours the concrete slab, heats the building to a minimum temperature the closes it up with no plans for ventilation. At some point in the future, the developer signs up a tenant and proceeds with the tenant fit-out. That is where our story begins.
