SV2 Vacuum Furnace
What is the muffle furnace definition and what is a furnace? These questions are easy for lab staffs. Today we would like to introduce a new vacuum furnace made by Lanphan company. SV2 vacuum furnace is a kind of industrial furnace who conducts heating by electrical heating element in vacuum condition, that is taking advantage of vacuum system(consists of vacuum pump , vacuum measuring equipment, vacuum valve) to discharge part of material in furnace chamber, so as to make intensity of pressure lower than standard atmospheric pressure, so that realize vacuum condition in furnace chamber. Lanphan SV2 vacuum furnace adopts with furnace transformer.
SV2 vacuum furnace’s working principle is on basis of conservation of energy, that is transfer electric energy to heat energy. When furnace is in normal working condition, apply voltage and current on heating element(resistance), heating element produces a large amount of heat in working room, and generates heat convection and heat radiation, thermal insulation material absorb and emit a few heat and isolate most heat to make working room temperature rise gradually, finally reach to pre-set temperature. When reach to certain temperature, thermocouple senses working room temperature and feedback to temperature control meter(PID control), then control voltage, current in order to control the thermal power of furnace, and reach pre-set program temperature.
Temperature control system
- Temperature control: PID self-controlling in temperature, digital display, upper limit alarm, deviation alarm, auto stop when program running is over, no need of person to watch over.
- Linear current output of temperature control meter, trigger phase shift anti parallel double direction controlled silicon.
- Temperature control thermocouple use K/S/indexing thermocouple.
A: over temperature alarm: when furnace temperature reach to alarm temperature, it will power off and alarm light on.
B: thermocouple broken alarm: thermocouple open circuit, instrument will alarm and automatic cut off power.
Vacuum and water-cooling system
- Double-layer water cooling carbon steel vacuum tank, semicircle end socket. Furnace door end socket is connected to chamber by 20mm-thick stainless steel flange, built-in silicone ring to seal, hand wheel is locked tightly.(silicone ring is protected by water cooling circulating).
- Vacuum set is composed of backing pumping and diffusion pump.
- Diameter of diffusion pump is 300, pumping speed is 5000L/S, ultimate vacuum is 10-5 Pa, twin-stage spin backing pump air inlet diameter 80mm, pumping speed 25L/S.
- Vacuum pump extract port is equipped with electromagnetism differential pressure regulator, to prevent suck-back if come across misoperation or sudden power lost.
- Vacuum tank is connected to vacuum pump by bellows, manual flapper valve control.
- Configure one inlet valve and one air vent valve.
- Equip with one water pump refrigeration water circulating.
- Max working vacuum degree: 7x10-3Pa(cold state). High temperature vacuum degree 7x10-2Pa.

- Except for man-made or abnormal operation to cause damage, we carry out “three guarantees”, warranty period for main engine is 3 years, please call us and tell fault reason if equipment is damaged.
- Free quality warranty period of the furnace is 3 years(except for heating element and easily smash and consumable matters), temperature controller , thermocouple, regulator, furnace transformer and voltage regulator’s guarantee period is 3 years, if heating element has natural damage within 3 months, we will change it for free.
- Furnace box temperature is more than 1000℃, will it hurt people?
Furnace shell adopts double-layer forced cooling, makes its shell temperature close to room temperature, no more than 40℃, in case of accident.
- How long will it take to heat the furnace to 1300℃?
Our max temperature rising rate is 40℃/min, it will cost 32.5 minutes to rise to 1300℃. We advice you to use heating rate of 20℃/min to lengthen equipment service life.
- Usually I only need 900℃ to conduct my experiment, can I have a furnace with max temperature of 1000℃?
Yes, we can custom-made the furnace according to your need.
- The setting temperature on display refers to hearth temperature or sample surface temperature?
When thermocouple is collecting temperature data, probe directly touch the tested material, not influenced by medium, so it is the actual temperature of sample surface.
