Overview
Bonis front 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 along with the optimum power of the heating elements, ensure that the kiln will operate at very high temperatures (up to 1300C), at very fast heating rates.
Features
Frame
The frame is constructed by forged metallic beams and corners. The external cover is made by metallic sheet, painted by a special fire proof colour.
Frame features the appropriate lifting points,so that kilns can be handled by manual lifting equipment.
Thermal Insulation
Multilayer insulation with total thickness of 14cm (kiln type MKF20 to MKF85) or 18cm (kiln type MKF150 to MKF720) It consists of special light weighted insulating firebricks (IFB), Grade 25, thickness 7.6cm, classification temperature 1350C, and a second layer (back up) of Grade 23 IFB, thickness 6.4cm. 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 on the insulating firebricks, and are fully protected. In all our kilns, heating elements are properly balanced, and designed in zones, taking so advantage of the natural potential of heat, achieving lower energy consumption, and ensuring absolute temperature uniformity.
Thermocouples
Kilns are equipped with an S type thermocouple (for maximum temperature 1300C), or with a K type thermocouple (for maximum temperature 1200C)
Door Safety
Kiln feature a door safety switch, which will cut off the power supply to the kilns elements in case someone opens the door while the kiln is in operation.
Arch Cosntruction
Models MKF85 to MKF730 feature a self-supporting, vaulted, arch ceiling
Observation Hole
Kilns feature obesrvation holes on the front side. Depending the model, kiln may feature one, two or three observation holes
Door seal
Door sealing firebricks, precisely placed by hand , along with heavy duty door toggle clamps, ensure tight sealing.
Exhaust air opening
Kilns feature an exhaust air opening in the center of the roof, which ensures proper ventilation of the kiln.
Heating Element Support System
Heating elements in models MKF150 to MKF730 are supported by special refractory shelves. They are made by insulating firebricks, they fully protect heating elements from damage, and can be easily replaced by the user.
Base moving on rails
Optionally, all kilns can feature a wagon type base, which moves on rails. Kiln base exits the kiln, allowing easy and ergonomic loading, especially of heavy, large ceramics
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
