Path of Sap in a Corsair Evaporator with Drop Flue Pan Set + Same Side Reverse System

This system enables you to easily reverse the flow in the front pan without ever moving the pan or dealing with plugs. Reversing flow is as simple as swinging the handles of two stainless steel ball valves. Our SSR System is the best in the industry. It is fully cross flow and has only one syrup outlet regardless of flow direction. The Same Side Reverse System (SSR) also works beautifully with the Smoky Lake Auto-Draw-off Systems.

(In contrast, our “standard configuration” Drop Flue Pan Set allows you to change direction of flow by turning the pan 180º.)

NOTE: Feature photo includes additional, optional components. (Sight Glass, Forced Draft System, Auto Draw-Off with Valve Assembly)

SSR Drop Flue Pan Set Bricking a Corsair

Four Reasons the Door Design is Critical

1Competitor doors/fireboxes are often much too small. In contrast, the 16″ x 16″ Corsair doorway makes it easier to load wood, and generate more heat.

2If you ever want to upgrade to Forced Draft — either now or in the future — you need an airtight door. With Corsair, you’re all set.

Regardless whether you have Forced Draft or Natural Draft, an airtight door increases efficiency. A leaky door works against you by allowing cold air to enter the firebox and cool your pans.

4Our competitors’ cast iron door fronts have been cracking since the 1800s. The Smoky Lake Corsair door will not. We guarantee it.
