Specifications subject to change without prior notice
- 230 volts, 3-phase, 50Hz
- Other electrical characteristics available
Inner oven floor reinforced for loading and equipped with removable grating. Oven top surface constructed of ¼" steel plate and workspace interior equipped with wear bars to prevent damage during loading. Automatic door opening mechanism consisting of solid steel shaft, bearings, and air cylinder system.
Each features completely wired, side access control panel enclosing terminals for incoming power, temperature controllers, push buttons and pilot lights. Motor starter and heating element contactors electrically interlocked to shut off heaters if power to blower is interrupted and to permit operation of blower without heat for cooling. Incoloy sheathed tubular heating elements. Exhaust outlet 4" diameter
- 1,000 BTU natural gas at 6" water column pressure, 1" NPT inlet
- Other gas characteristics available
Control panel as detailed above and safety devices as listed on the front of this bulletin. Automatic preignition purge period and pushbutton electric ignition contributes to ease of operation. Modulating gas burner is protected with electronic flame safety relay.
These electric or gas ovens come in four sizes. They feature full horizontal airflow with adjustable patented opposed louvers for balanced airflow. The horizontal airflow pattern allows heated air to pass between stacked parts for uniform heating. High volume recirculating blowers are specifically designed for heating heavy loads.
The removable grating on the oven floor protects the oven from impact during loading and distributes concentrated loads across the entire oven floor. The grating allows for air movement beneath the work for uniform processing.
The LA and LC series have the heat chamber located to the rear of the workspace. ON the LB and LD Series, the heat chamber is located to the right side of the workspace to position the supply and return ductwork at the front and rear of the workspace respectively. This provides the shortest distance between ducts, which minimizes the temperature differential across the workspace.
1000oF Models Only.
Insulated with 2" of 10500C insulating block backed up with 6750C industrial rockwool. 16 gauge aluminized steelwork space interior; 304 stainless steel heat chamber interior with stainless steel recirculating blower. Gas models include stainless steel exhauster.
