Multipurpose furnaces streamline loading and unloading

| By Chemical Engineering

L&L Special Furnace

New GS2026 bench-mounted box furnaces (photo) include a spring-assist vertical-lift door that allows for effortless loading and unloading even at high temperatures. The furnaces are controlled by an industrial control system that includes a Eurotherm temperature control, overtemperature protection and a recirculation fan for uniformity. The heating elements are located on both sides and at the top and bottom, which enables equal heat distribution from all sides. This element distribution can achieve a uniformity gradient of ±10°F. Standard units include a sheathed thermocouple, a slot in the door for access into the furnace, a powder-coated machined case, ceramic hearth plate with standoffs, a door limit switch that turns the power to the elements off if the door is opened, an on/off toggle switch with control fusing and a power plug. An optional angle iron stand and vent kit are also available. The GS2026 has an operating voltage of 208, 220 or 240 V single-phase, 60 or 50 Hz. — L&L Special Furnace Co., Aston, Pa.
