Working volume and outer envelope
State internal width, height and depth as well as the maximum external dimensions. Include the door overlap, threshold, supports and any restricted area around the furnace casing.

02Overview
Muffle and box chambers are supplied as a formed hot-face body, an assembled chamber set or an element-integrated heating component. Quote data should separate the internal working volume from the maximum outer envelope and identify the door interface, hearth or base, vents, observation ports, thermocouple position, element material, voltage, power and terminal direction. These values determine whether a one-piece, sectional or framed construction is practical.

Box-type heater module sizes
Box-type modules combine ceramic fiber insulation with a resistance-wire heating layout. Suitable configurations can be specified for continuous operation up to 1350°C, depending on the element alloy, electrical loading and process atmosphere. Specify the usable hot zone and maximum outer dimensions separately. Reference module sizes below are in mm; the quotation drawing identifies the working space, wall thickness and outer envelope.

05Selection guide
Choose the chamber construction before fixing element details.
A muffle furnace chamber quotation separates the usable hot zone from the outer installation envelope, then defines the wall build-up, door fit, temperature cycle and electrical interfaces. Record both internal and external dimensions instead of using a nominal chamber size alone.
Temperature profile and atmosphere
Provide normal and maximum operating temperature, ramp and hold pattern, cycle frequency, furnace atmosphere and typical load. These conditions determine the grade, wall construction and element selection.
Heating and access interfaces
Define voltage, power, phase, preferred element type, thermocouple position, vents, observation ports and lead direction. Mark each opening on the chamber drawing.

ProjectProduct configuration
400 × 300 × 300 mm muffle chamber
This rectangular muffle chamber has a 400 × 300 × 300 mm working space, a 1500-grade ceramic fiber body and spiral heating elements mounted along the side walls.
The size table covers compact and larger box-furnace chambers. Other dimensions can be made from a drawing or measured sample.
Choose a formed body or a matched multi-piece chamber according to size, access and manufacturing requirements.
A single chamber can be used to check fit and electrical details before repeat production.
08Product FAQ
Common questions about muffle chamber dimensions and ordering.
01Can you manufacture a chamber from our drawing?+
Yes. A drawing, marked-up photo or reference sample can be used to confirm dimensions, openings, element layout and mounting interfaces.
02Are the listed chamber sizes fixed?+
No. The standard-size list is a reference. Internal dimensions, wall thickness, external envelope and door structure can be customized.
03Can the heating elements be supplied with the chamber?+
Yes. Element type, distribution, voltage, power, lead exits and terminal arrangement are engineered as part of the complete chamber design.
04Can I order one sample?+
Yes. MOQ can be one unit or a sample, followed by repeat production after validation.
