Used NATIONAL 5851 #9126413 for sale

NATIONAL 5851 is a high-performance gas-fired oven / furnace specifically designed for industrial and laboratory applications. The furnace is built to provide an efficient and effective means of heating materials to extremely high temperatures. The furnace is constructed of aluminized steel for durability and to ensure that no combustible materials are heated in excess of the maximum temperatures. The walls and roof are double-skinned, providing excellent thermal efficiency. The furnace is equipped with an electronic ignition system which is controlled by a digital thermocouple-based temperature controller. This controller allows for precise setting and adjustment of temperatures from room temperature up to 2600°F (1427°C). The furnace chamber is designed to facilitate uniform heating throughout the entire interior space. To ensure even heating, there are two layers of ceramic fiber lining, including a high-temperature seal around the inner liner and ceramic plates along each wall. The ceramic plates help direct air flow through the heating zone for even distribution and temperature uniformity. The furnace is also equipped with twelve blower fans and two adjustable louvers for adjustable air flow for optimal temperature control. 5851 utilizes two combustion chambers, each powered by four pressure-regulated burners. These burners provide precise fuel-air mixing and efficient combustion. Depending on the type of fuel gas available, the burners can be configured for natural gas, LP, or propane operation. Individual safety features are provided to protect operators and ensure safe operations. These features include automatic burner shut-off in the event of inadequate ventilation or high temperatures, an overheat/over-pressure control panel, an emergency stop switch, pressure windows for monitoring temperatures, and a pressure switch to shut off fuel flow when the pressure in the heat chamber is too high. NATIONAL 5851 has been designed to provide reliable, efficient, and uniform heating of laboratory materials. Its functional design, safety features, and quality construction ensure that it can serve your laboratory needs for years to come.
