High-Temperature Furnaces
Achieve temperatures as high as 1200° C for heat-treating metal.
76 and 128-cu. in. capacity furnaces have an LED that shows actual or set-point temperature in ° C; an indicator light flashes when set temperature is reached. The safety switch shuts off the furnace when the door is opened.

Programmable High-Temperature Furnaces
Program time, temperature, and rate of temperature change. These furnaces reach temperatures as high as 2192° F for heat-treating metal. These furnaces have six programmable parameters: 1) delay start, 2) rate of temperature change, 3) target temperature, 4) temperature timer, 5) memory retrieval, and 6) °C/°F digital display. Link two three-stage programs to create a six-stage operation. A maximum of 10 programs can be stored with up to a seven-day delay. An LCD shows internal temperature, countdown time, and program number.

Ovens
Also known as gravity convection and laboratory ovens, heat rises from the base into the oven chamber and out through the top vents. Use these general purpose ovens for heating and curing up to 437° F. The control components are CSA certified and UL recognized.

Quenching Oil
For controlled cooling, use quenching oil instead of water to minimize cracking and distortion after heat treating parts and tools. It's nonstaining and chlorine and sulfur free. Use full strength.
Abrasion-Resistant Firebrick Insulation
- Temperature Range: 0° to 2900° F
- Heat Flow Rate: 9.6 Btu @ 1500° F
- Density: See Table
- Color: Beige
- Specifications Met: See Table
Stronger than standard firebricks but with lower insulation capabilities, these withstand heavy abrasion on the floors and sides of furnaces. They meet ASTM standards for flame resistance. Also known as hard firebricks. Cut with a diamond-tipped tile saw and install with firebrick bonding mortar (sold separately).

Grease
Use this general purpose grease to lubricate most machinery.
NLGI viscosity grade is a rating of a grease's consistency. NLGI 2 is about the consistency of peanut butter.
Mineral-oil-based grease, derived from petroleum, is usually more economical than synthetic-oil-based grease. Grease with aluminum thickener has good moisture resistance and excellent oxidation resistance. Grease lubricates most efficiently within the listed temperature range. Melting temperate is the point at which grease will fail and run out of equipment, leaving it to run dry.
