Corsair Arch

This revolutionary evaporator design is fully convertible from conventional draft to forced draft in an instant. The airtight front gives you a critical advantage in efficiency and performance whether you’re running the forced air kit or if you choose to keep things simple with natural aspiration. 

The large loading door nicely compliments the large combustion chamber. This air-tight door will help prevent cold air from being pulled along the bottom of pan, negatively effecting evaporation rate and efficiency. 

The Corsair arch is fully steel framed. The entire perimeter is built as strong as possible, giving you confidence when filling the pans above it with your precious liquid and igniting an intense fire inside it. Additionally, the arch fits the geometry of whatever pan set you plan to use on it, forcing the pan to take full advantage of the heat created within. 

As of May 2, 2022, we are transitioning all of our Corsair Arches to include the Stainless Steel Upgrade. This feature is loved not only for its aesthetic beauty, but most important for its durability. Stainless steel resists rust and is extremely resilient in intense heat. It is guaranteed to outlive galvanized steel.

As of Summer 2023, all Corsair Arches include the precut brick kit upgrade as a standard feature.

The Stainless Steel upgrade applies to the Corsair Arch Sides, Base Stack and Stack Pipe as called out in the photo below.
