Overview

Bonis round top load kilns for firing ceramics are high quality professional equipment that fully meets the requirements of the modern studios.
Made from high quality raw materials ,produced by the best European companies, for guaranteed performance and long life span.
Their multilayer insulation combined with the high insulating capacity of the materials used, ensure high energy saving, and slow cooling rates.
The combination of our unique multi layer insulation together with the appropriate power of the heating elements, ensure that the furnace will operate at very high temperatures (up to 1300C), at very fast heating rates.

Features

Frame

The frame of the kiln is made by stainless steel.
All kilns come with a steel frame base which can optionally carry wheels.

Thermal Insulation

Multilayer insulation with total thickness of 13cm, consisting of special light weighted insulating firebricks (IFB), Grade 25, thickness 7.6cm, classification temperature 1350C, and two layers of non hazardous, low biopersistent Cerablanket, density 128kg / m3 with total thickness 5cm.
Multi-layer insulation offers great energy savings.

Heating Elements

Heating elements are made by Kanthal class A1 wire, able to withstand up to 1340C.
They are mounted in specially designed grooves, and are fully protected.
Heating elements are designed in zones. In this way we take advantage of the natural potential of heat, achieve lower energy consumption, and ensure temperature uniformity throughout the furnace.

Thermocouples

Kilns are equipped with an S type thermocouple (for maximum temperature 1300C), or K type thermocouple (for maximum temperature 1200C and 1250C)

Control Panel

The electric panel is constructed from stainless steel. It is equipped with all the necessary indication lights, switches and the conductors needed to connect the kiln to the main power supply.

Lid Support

All kilns feature a three position lid support. Lateral support provides great security, while less stress is transferred on the kilns frame.
The third mounting position allows to open for a few centimeters, for rapid cooling of the furnace.

Disassembly

All kilns are easily dismantled without the need to use any specialized tools.
Kilns are made in such a way that the disassembly of the electrical or electronic components is not required.
This makes it very easy to transport the kiln, and to place it in areas with limited accesibility (the minimum door opening required is 45cm)

Optional Features

Silent operation.

Heating elements on the floor.

Handle with lock on the lid.

Ventilation system.

Wheels on the metallic support.

Temperature Control

Kiln models with internal height up to 58cm, feature a single zone temperature control system. These kilns are equipped with the controller ST 215.
Kiln with internal height 69cm can be upgraded to a a multi-zone temperature control system.
The multi-zone temperature control system features three thermocouples and the temperature control is carried out in three different zones (upper zone, middle zone, bottom zone).
In kilns of large internal height, our multi-zone temperature control ensures complete temperature uniformity throughout the kiln, regardless of uneven ceramic loading, heating element condition, etc.
Multizone temperature control kilns are equipped with the ST535 controller.

Both controllers are easy and practical to use, and they are equipped with the most advanced features. The state of the art technology used to manufacture the controllers and high quality performance, guarantees safe firing and precise temperature control. Controllers are detachable and can be easily detached from the kiln for use in another kiln, or to be stored.

Both controller features:
- 32 programms each with 32 segments
- Free segment programming
- Segment comprises of 1 heating / cooling ramp followed by a soak period
- Segment is programmed as target temperature and ramp rate (C or F per hour)
- Ramp rate from 1 to 999/hour and Full power
- Programs can be altered while firing
- Program pause while firing (dwell / soak during pause)
- Program advance facilities (Skip Segment)
- Keyboard Lock
- Delayed Start facility (up to 99 hours 59 mins)
- Power failure recovery
- Energy used display (even during running a program, it will display the energy used up to this point)
- Set point display
- C / F operation

Optionaly, both controllers can have the capability to be accessed and controlled remotely from your mobile, laptop or tablet.
Using 'MyKiln" portal site you can view and control your kiln in real time. You can Stop a firing or adjust programs, from anywhere in the world.
WiFi enabled controllers feature also a USB port that allows you to directly control it from a PC and it also allows us to apply updates and run diagnostics from distance
