KILN selection
Determine the right kiln for your needs.
The creative process begins with the choice of the type of energy used in your firing processes. ROHDE kilns are electric.
Advantages of electrically operated kilns:
- Fully automated and precise control of the firing process using intuitive controllers
- Easy and reproducible control of the firing process using storable firing programs
- Runs automatically without the need for monitoring of the firing process
The kiln size is determined by the size of the ware to be fired and the firing frequency. If you fire mainly different sizes or very small pieces, ROHDE recommends that you purchase two smaller kilns instead of just one large one. Large kilns only work economically if they are tightly loaded. However, large individual pieces require a bigger kiln.
When considering the details for interior dimensions, consider a buffer in space for unheated areas and heating elements.
Keep in mind the transport and movement of your kiln to its operating location and make appropriate arrangements.
The choice depends on your individual conditions and requirements:
- Top loading: good overview of the firing chamber – choose a toploader
- Front loading: effective use of kiln height – choose a chamber kiln. Optimal efficiency, safety, and ergonomics – the ELS Ergo Load System
The technically solid dimensioning of each heating element and the use of high-quality Kanthal wire are important requirements for the highest performance and efficiency. When it comes to exact calculation, ROHDE considers a low surface load, a good gradient factor, and the highest possible wire strength as decisive factors for durability and power reserve.
Efficient accessories and additional equipment make daily work easier.
First, consider available features and then choose according to your requirements:
- Controller: easy and intuitive to operate, detachable, safe over-temperature cut-out
- Safety: door safety switch, low external temperature, lockable kiln door
- Exhaust air: good air ventilation of the firing chamber using exhaust air and air supply slides or an exhaust air socket.
The quality of a kiln is primarily determined by criteria such as durability, firing results, functional safety, energy consumption, and the need for spare parts.
The design of ROHDE products is outstanding across all these aspects, providing the highest level of product confidence. High-quality material and construction properties, such as a V2A stainless steel jacket or a completely ventilated steel frame, guarantee the highest quality and corrosion protection.
The top and walls are joined mortar-free, making them not only attractive but also allowing the kiln to expand naturally, preventing cracks and particles from falling from the ceiling onto the ware. These are optimal prerequisites for a long service life, reliable functionality, and first-class results.
Firing and application Temperature
When it comes to temperature information, we differentiate between the application temperature and the maximum temperature.
Maximum temperature
The maximum temperature (Tmax) is the maximum temperature defined by ROHDE at which a kiln can be safely operated. All materials used are designed in such a way that when used as intended in accordance with the operating instructions, up to the specified Tmax no damage is caused to the kiln or the surrounding area. This value contains no buffer and must not be exceeded.
Application temperature
The different series and products in our range are designed in such a way that they can be used reliably for the specified application temperature (Tapp), i.e. optimally and continuously.
