USED 2013 LINDBERG / BLUE M BF51766C-1

Lindberg Blue M BF51766C-1 1100°C Digital Box Furnace (Plus Identical Repairable Spare Unit)Up for sale is a high-value industrial/laboratory package featuring two identical Lindberg Blue M Model BF51766C-1 Moldatherm Box Furnaces sold together as a complete lot.Unit #1: Fully operational, bench-tested to temperature, and clean.Unit #2: Included as a complete, identical spare unit. The chamber, shell, control assembly, and door are intact, but it exhibits outer shroud damage from shipping.Engineered by Thermo Scientific, this high-temperature benchtop series features a 5.3-liter (0.19 cu. ft.) chamber capacity and is capable of stable, continuous heating applications up to 1100°C (2012°F). Equipped with an advanced digital microprocessor PID controller, these furnaces ensure ultra-precise temperature regulation with minimal overshoot. This package represents a massive cost savings opportunity and instant fleet redundancy for materials testing, laboratory analysis, ash testing, or industrial component heat-treating.High-Value Key FeaturesMolded Moldatherm® Heating Elements: Features Lindberg's proprietary ceramic fiber insulation with fully embedded heating elements. This patented design ensures maximum heat distribution uniformity across the chamber, quick ramp-up/cool-down rates, and excellent structural thermal efficiency.Instant Redundancy Package: Having an identical second unit on hand gives your maintenance team an instant repository of high-dollar spare parts—including the digital microprocessor PID controller board, solid-state relays, Type K thermocouple, side-hinge door assembly, and safety switches.Double-Wall Air-Jacketed Construction: Built with an advanced double-wall cabinet configuration that minimizes exterior shell surface temperatures, enhancing operator safety and reducing ambient heat load on your workshop or laboratory floor.Integrated Safety Features: Includes a built-in safety door switch that instantly cuts power to the heating elements when the side-hinge door is opened, eliminating electrical exposure risk. Features an adjustable, independent high-limit Over-Temperature Protection (OTP) safeguard.Exhaust & Atmosphere Ports: Outfitted with a 1-inch diameter top exhaust vent and a 0.375-inch rear air inlet, allowing for controlled gas or inert atmosphere exchanges when necessary.Technical Specifications (Per Unit)Model Number: BF51766C-1Chamber Capacity: 5.3 Liters (0.19 cu. ft.)Temperature Operating Range: 100°C to 1100°C (212°F to 2012°F)Controller Type: Digital Single-Setpoint PID Control with adjustable Over-Temperature Protection (OTP)Electrical Profile: 208/240 Volts | Single Phase | 50/60 Hz | 1800 Watts (7.5 Amps)Thermocouple Type: Long-life Type KChamber Interior Dimensions: 9" D x 6" W x 6" H (22.9 x 15.2 x 15.2 cm)Overall Exterior Dimensions: 21" L x 17" W x 21.5" H (53.3 x 43.1 x 54.6 cm)Unit Net Weight: 110 lbs (220 lbs total for the pair)
