Industrial muffle furnace 45 liter up to 1093 °C with five shelf positions

The Thermo Scientific Thermolyne industrial muffle furnace is designed for laboratories and industrial environments handling large sample volumes or high sample throughput. As a result, this model offers the largest tabletop chamber in the Thermolyne line: a 45 liter space (36 × 36 × 36 cm). Specifically, the temperature range is 100 to 1093 °C, with stability of ± 1.2 °C and uniformity of ± 3.5 °C at 1000 °C. Furthermore, heating elements are positioned on the top, bottom, and sides of the chamber, delivering even heat distribution across the entire work surface.

Five shelf positions and two included shelves

Specifically, the chamber features five different shelf positions, allowing you to tailor the loading layout to the dimensions of your samples. Notably, two refractory shelves (SH412X1) are included as standard, which triples the effective work surface compared to a single loading layer. As a result, you can treat multiple samples at once or process larger parts without compromising chamber accessibility.

Three controller choices for your process

Specifically, you choose from three PID microprocessor controllers depending on the complexity of your application:

• F30420C-33 (B1): Single setpoint with ramp to setpoint and dwell function. Specifically suitable for controlled heatup curves with a hold period when no multi-segment profile is required.
• F30420C-33-80 (C1): Programmable with 1 stored program of 8 segments. As a result, more complex thermal profiles become possible, for example stepwise heating followed by controlled cooldown.
• F30430CM-33 (D1): Programmable with 5 stored programs of 16 segments each, plus RS-232 communications. In addition, suitable for labs that want to log data or remotely monitor from a PC.

Furthermore, all three models feature a Platinel II thermocouple and user-selectable OTP for added safety during extended processes.

Applications in lab and industry

Specifically, this industrial muffle furnace is used for applications that require both large sample volumes and reproducible results. Common applications include:

• Large-scale ashing and gravimetric analysis
• Heat treatment of metal parts and tooling
• Sintering and bonding of ceramics and glass
• Thermal decomposition and pyrolysis
• High sample throughput in pilot plants and R&D
• Thermal expansion and viscosity testing

In addition, this model is regularly used in materials research, quality control in production environments, and in the food industry for combustion analysis on large sample batches.

Safety and operation

Moreover, this industrial muffle furnace features multiple safety functions matched to the high 5500 W power. Specifically, a 35 A circuit breaker protects the critical electronic components and heating elements against overload. Furthermore, the door switch interrupts power to the heating elements when the door opens. Notably, user-selectable OTP provides an adjustable layer of overheating protection, while open thermocouple protection cuts heating when a sensor fails. In addition, the built-in vent port removes fumes and moisture directly, and a 0.64 cm diameter port at the rear allows independent temperature measurement.

Standard and optional accessories

Each industrial muffle furnace ships with a Platinel II thermocouple and two refractory shelves (SH412X1). As a result, the unit is immediately ready for applications that use the full work surface. In addition, a hearth tray (PH480X1) is optionally available for extra floor protection, plus a stainless steel exhaust kit (AY408X1A, 2.5 inch ID, 5 ft length) for connection to an exhaust system.

Note: all EU models require hardwiring by a qualified technician. Specifically, no plug or power cord is supplied, because the 5500 W power demands a fixed electrical connection.
