AREAS OF APPLICATION
The muffle/chamber furnace is designed for thermal technology applications in the laboratory:
Volume of furnace work chamber 4.7 1 (M 104) or 3.8 1 (K 114)
Heat treatment of samples and objects from 300 °C to 1000 °C (M 104) or to 1100 °C (K 114)
Loads of up to 5 kg
The unit is generally designed for installation and operation in the following areas:
Laboratories, such as those found in manufacturing trades and industry, schools, universities, hospitals and biology.
lt is used for:
ageing, analysis, tempering, decomposing, baking, annealing, hardening, soldering, oxidising, reducing, incineration and preheating.
The over-temperature protection "upper limit cut-out" which can be supplied with the unit enables operation without constant supervision.
The unit is designed for continuous operation.
To avoid samples being unevenly exposed to heat, care must be taken to maintain a distance from the inner surfaces of the furnace work chamber.
Provisions should always be made to provide operators with protective clothing, such as working gloves and protective glasses, due to the often high temperatures existing in the working environment.
Do not use the unit:
- to heat up foods
- for drying or heat treatment of substances which release gases or vapours Into the atmosphere that are flammable or dangerously explosive when mixed with air. This furnace is equally unsuitable for the heat treatment of combustible dusts and fibrous materials.
DESCRIPTION OF UNIT
The basic design of the unit comprises casing, work chamber, tilting door and switching and controlling components.
The work chamber of the M104 laboratory muffle furnace consists of a ceramic muffle. The heating elements are covered and embedded in the muffle. The muffle furnace is designed to operate at temperatures of up to 1000 °C.
The work chamber of the K 114 laboratory muffle furnace consists of fiberboard. Exposed heating elements are set into grooves in the walls and ceiling of the furnace chamber. A ceramic plate covers the floor of the furnace chamber. The unit is designed to work at operating temperatures of up to 1100°C.
Fiber materials provide the unit with thermal insulation showing reliably good heat containment properties and temperature/time parameters.
The metal surfaces around the mouth of the furnace can become extremely hot during Operation at high temperatures. Care must be taken against the danger of injury. To warn against touching them, these surfaces have accordingly been marked with the Symbol shown here.
The furnace chamber is closed off by a tilting door.
The door is opened and closed with a lever on the right side of the unit. The hot interior side of the door swings downward when the door is opened. An integrated protective shield against escaping heat and heated particles simultaneously folds out. The lowered door then serves as a surface on which the unloaded samples can be placed.
There is an aperture (Ø 5 mm) in the middle of the swing door which serves as an access for encased thermocouples providing external measurement of temperatures inside the furnace chamber.
Special measures must be taken and strictly observed to ensure protection of persons from electrical shock when using external temperature measurement devices. Failure to observe these measures is EXTREMELY HAZARDOUS and presents a DANGER of DAMAGE TO ALL CONNECTED SYSTEMS - please refer to instructions in the appropriate section of this manual.
The operating elements for built-in electrical components are integrated into the operating panel of the switching and control unit.
The unit is designed as a plug-in unit and is supplied with a fixed mains connection. A PE conductor (protection class 1) provides protection against electrical shock.
The laboratory furnace is equipped with radio interference suppression.
Temperature control is provided by an electronic temperature controller featuring a sensor defect indicator. The interior temperature is measured by a thermocouple. A power semiconductor in the temperature controller regulates the power supplied for heating.
SAFETY STANDARDS
The unit meets the following safety standards:
DIN 12 880 Section 1 / 11.78
DIN VDE 0700 Section 1 / 04.88
DIN VDE 0875 Section 11 / 07.92
The M 104 / K 114 laboratory muffle and chamber furnaces have also been safety-tested by the testing and certification institute VDE. Certain models (see APPENDIX) comply with GS certification standards and with interference standards, depending the optional equipment installed.
