Product evidence

Product views and construction details.

Square external furnace chamber with a cylindrical heated space and installed resistance wire — Internal hot space, outer profile, element route and terminal positions are dimensioned as separate integration boundaries.

Two-part curved furnace chamber with resistance-wire grooves and external leads — Split lines, opening geometry, movement, element routing and service leads are coordinated around the installed equipment.

Product configuration

Configuration overview

Application fit: OEM furnace integration, replacement projects and specialized laboratory or industrial heating equipment requiring box, cylindrical, curved, split or application-specific chamber geometry.
Temperature / cycle: Defined by the selected configuration and required working cycle. Working and maximum values must be confirmed separately.
Geometry: Dimensioned internal space, external envelope, openings, wall sections, split or movement lines, mounting features, terminal positions and service clearances are required.
Atmosphere boundary: The chamber assembly provides the heated and insulated geometry; any vacuum, pressure or controlled-atmosphere seal must be defined as a separate process boundary.
Heating / connection: Element material, groove or support layout, zone arrangement, resistance or power target, leads, terminals and sensor position are developed with the chamber geometry.

Shape the heated chamber around the equipment interface

A custom furnace chamber begins with the space that must be heated and the machine that surrounds it. Box, cylindrical, curved and split constructions can be developed for different loads, process tubes, access directions and enclosure limits. Pyrocore treats the chamber as an integrated heated assembly; loose refractory board, blanket and paper are outside this product scope.

Separate internal, chamber and machine dimensions

Provide dimensioned views that distinguish the usable hot space from the insulation body and the surrounding equipment envelope. Mark doors, tube openings, observation or sensor ports, supports, flanges, terminal guards and maintenance clearances. For a replacement project, include both the original chamber dimensions and verified measurements from the machine.

Select a geometry that supports the heat path

Rectangular chambers suit many front-loading arrangements, while cylindrical and curved sections can follow a tube, vessel or round load. Split constructions allow access around an installed component or process tube. The joint location, movement direction and closing method should be established before the element route is finalized.

Integrate element grooves, zones and terminals

The chamber photographs show several ways of arranging resistance wire within shaped grooves. The final route depends on the required hot zone, available wall area, electrical design and service access. State the supply, power or resistance target, number of control zones and preferred terminal locations. Alternative element systems can be reviewed when supported by the furnace temperature and process duty.

Position sensing around the actual load

Temperature-sensor type and insertion position should be shown on the drawing. The sensor opening, element clearances and load position must not be developed independently. If more than one zone is required, identify the intended zone boundaries and how performance will be evaluated in the assembled equipment.

Define the atmosphere and enclosure boundary

A shaped insulated chamber does not automatically create a vacuum-tight or gas-tight vessel. Identify the component that contains the process atmosphere, its seals and the interface between that boundary and the heated chamber. Also describe ventilation, vapours, contamination sensitivity and any mechanical protection required around the insulation assembly.
