Uses: These models are designed for those users who require automatic temperature controlled furnaces from 250° F to 2000° F (Model C-601) or up to 2250° F (Model C401H)
At A Low Cost: An ideal unit for many of the small jobs found in Tool rooms, Production Shops or Laboratory.
Temperature Control: Auto tuning microprocessor-based controller.
Elements: C-601 chrome nickel wire. C401H-high temperature iron-aluminum wire.
Uses: These furnaces are designed for general use in the shop, laboratory or factory where temperatures from 300°F to 2250° F are required. They are used for heat treating metal, assaying and all types of testing.
Temperature controls: Auto tuning microprocessor-based controller.
Elements: High temperature iron-aluminum alloy wire elements are coiled and mounted on the side wall in porcelain plates.
"Heat Treating Furnaces" also known as hardening furnaces
Heat treat (Hardening) furnaces have higher heat output power than draw furnaces due to the elevated temperatures at which they operate. Heat transfer to the tool steel is accomplished by a very efficient process called direct radiation. Temperature uniformity in these furnaces is best in the red heat range. Normal maximum temperature is 1232°C (2250°F). Optional 1316°C (2400°F.) maximum temperature versions are available.
Uses: These furnaces are designed for general use in the shop, laboratory or factory where temperatures from 300°F to 2250°F ±25 °F are required. They are used for heat treating metal, assaying and all types of testing. 2400° F maximum temperature option available at additional cost.
Uses: Designed for those who desire a hardening furnace, a quench tank plus a separate furnace for tempering or drawing all within a Minimum floor space. The two chambers allow for immediate tempering or drawing after quench without waiting for the hardening furnace to cool to the lower temperature required.
Controls: Both chambers are equipped with their own electronic control, thermocouples and solid state relays.
Uses: This large capacity furnace can be used for various types of heat treatment processes which require temperatures up to 2100°F continuos temperature or 2250°F intermittent.
Controls: These furnaces come standard with a digital programmable main control and a digital high limit safety control. Solid state power switching to the heating elements, and dual door limit safety switches that interrupt power to the elements when the door is opened.
"Draw Furnaces" also known as annealing, tempering or forced
Draw furnaces are used for tempering and other low temperature processes. They normally operate at temperatures below red heat range where heat transfer to the tool steel is accomplished by the process of convection heat transfer. To increase convection efficiency, these furnaces are equipped with a fan in the heating chamber to move air (Forced Convection). This delivers a temperature uniformity of ± 6°C (± 10°F)
Uses: These furnaces are designed for heavy duty, larger volume jobs requiring controlled temperatures up to 2100°F continuous or 2250°F intermittent.
Controls: These furnace come standard with a digital programmable main control and a digital high limit safety control. Solid state power switching to the heating elements, and dual door limit safety switches that interrupt power to the elements when the door is opened.
Uses: Designed for those who desire a large hardening furnace plus a separate furnace for tempering or drawing, all within a Minimum floor space. The two chambers allow for immediate tempering or drawing after quench without waiting for the hardening furnace to cool to the lower temperature required.
Controls: These furnaces come standard with two sets of individual digital programmable control and a digital high limit safety control. Solid state power switching to the heating elements. Each chamber is equipped with dual door limit safety switches that interrupt power to the elements when the door is opened. Fan stops when lower door is opened. (Note: door blocks view of the lower set of controls)
Uses: These bottom opening quick quench furnaces, are designed for aluminum heat treatment to a maximum temperature of 1200 ºF. Temperature gradients are ± 5 ºF or less.
Controls: These furnaces come standard with a Model SD, digital LED readout microprocessor programmable control mounted in a separate free standing control cabinet. T
