Gruenberg has always been known for heavy-duty construction and innovative custom solutions, but the truth is, their expertise is every bit as impressive when it comes to standard, ready-to-ship options. And with so many top-quality Truck-In ovens on hand and ready to order, why should anyone settle for anything less than Gruenberg? Every oven is built around a welded, structural steel frame with separate, insulated inner and outer surfaces. Pliable, silicone rubber gaskets create a final seal on oven with temperatures up to 650°F. Proprietary CHIL technology means better energy use and more controllable temperature. +/- 1.5% Uniformity 650 degrees
