This inexpensive heavy duty furnace is ideal for small and medium sized casting shops. The elements are deeply recessed to avoid damage by tongs. Supplied with wax elimination tray. Specification: Internal chamber dimensions: (229 x 229 x 229 mm) External 457 x 533 x 597mm
The units are constructed from the latest high temperature insulation refractories comprising an ultra-efficient brick hot face and back-up insulation to give a 150mm thick wall of exceptionally low conductivity. This ensures extremly low heat loss, very low external temperatures and low firing costs. Elements, in higest grade Kanthal for long life and fast economical performance up to 1300 degrees C. are fitted to both sides of the walls, with large spy hole in front of door and vent in the roof.
The unit is supplied with an ST-215 controller as detailed below.

The ST215 is a small easy to use ergonomically designed controller in a hand-held case with rubber hand grips. It is supplied with a wall mounting holster bracket and a flexible lead and plug as standard. Bright orange LED displays are fitted. The ST215 is designed to control single zone electric kilns and is derived from our long established ST315 controller. It is suitable for worldwide use with a universal power supply and selectable °C/°F operation. For a traditional pottery firing controller please see our ST216 (separate datasheet). This is in the same product range as the ST215 controller and has 80 programs.
The ST215 is a 10-program controller designed for glass, ceramics & pottery use. Each program can have up to 16 segments. It is fully adjustable with a detailed 4-lamp mimic display & continuous display of segment number. Each segment comprises of a ramp followed by a soak. Ramps can be heating or cooling. It executes a controlled ramp to the soak temperature where it dwells for the required period then executes the next segment. The end of the program is marked by selecting ‘End’ while entering a ramp rate. Natural cooling then follows.
The ST215 can be configured to the kiln using a configuration menu. The thermocouple type and kiln power rating (for the energy used function) can be configured together with °C/°F operation. Other installer-configurable items include power failure recovery enable/disable, error message handling and control parameters.
