1400C University Lab Vacuum Tubular Furnace with Multiple Tube Sizes

Type

Bench-top;Vacuum Atmosphere

Furnace Structure

The furnace is made of carbon steel with powder coating on surface, integrate furnace body and heating system and controller system in one.

Diameter

Ф80

Heating Zone

Single Heating Zone 300mm

Tube Size

Ф80x800mm length

Max. Working Temp.

1400°C

Constant Working Temp.

1300°C

Min. Working Temp.

Ambient

Heating Rate

Fast heat-up time due to the low thermal mass construction

Suggest 5~20℃/min for longer life using of furnace

Temp. Homogeneity

Adopt the way of measuring temperature at 9-point

Temperature homogeneity is +/-5 degree

Power Supply

AC220V; 4KW

50Hz, single phase

Chamber Material

1. Adopt high quality 1500 grade alumina polycrystalline fiber, which used Japanese technology (vac-sorb forming alumina polycrystalline fiber) with good insulation and durability properties, high tensile strength and no miscellaneous ball, this furnace much more energy saving than the furnace use common fiber materials               

2. One-piece chamber and ecological insulation provide high thermal efficiency

Heating Element

1. High quality U shape Silicon Carbide rods

2. Vertical layout, distributes in two sides evenly, give an improved temperature gradient

Resistance of a SiC rods heating element does not change under normal use, and you can mix new and old elements together.

Thermocouple

Type S

Installation location:top center

Vacuum Flange

One set of Vaccum sealing flanges: Mechanical vacuum gauge andsealing flanges mounted on the quartz tube, ensured the installation very convenient and vacuum level precisely.

Sealing performance

Double furnace door structure, inner door block the fire, outer door is sealed with flanges, high temperature

PTFE gasket is installed on the outer furnace door to ensure the reliable sealing of the furnace; the furnace

body is equipped with an air intlet, which can extract vacuum; The tank body is designed with a circular flange

and conforms to the pressure vessel manufacturing method, the shell will not be deformed for long-term use,

and it has better sealing performance than the square style

Temperature Controller

1. Digital Shimaden SRS13A(Japan) with 4 programs and 32 segments

2. Simultaneous LED display of actual temperature VS set point

3. PID automatic control and auto-tune function

4. +/- 1 ºC temperature accuracy

5. Control system integrated in furnace base, defined application within the constraints of the operating instructions  

Electronic Component

SCHNEIDER maker air switch, solid-state relay, A.C contactor etc.

Furnace Shell

1. High quality cold-rolled steel sheets CNC processing

2. Environmental electrostatic plastic powder coating on surface after deoiling, derusting, phosphating etc.

3. Energy efficient insulation keeps exterior safe to touch

Furnace Door

Door opens sideways

Manual type

Safety Precautions

1. Overheating & Broken thermocouple protection

2. Leakage circuit breaker

3. Automatic power off when furnace door opens

4. Over-temperature protection and alarm allow for operation without attendant(s)

5. Microprocessor-based PID control with self-tuning capability to prevent overshooting of set temperature

Certification

CE compliance

Supply Scope

1. One set of tube furnace body

2. one piece of alumina tube

3. three-meter power line

4. One piece of S-TYPE thermocouple

5. One furnace hook

6. One pair of high temperature furnace gloves

7. An instruction book

8. Two ceramic blocks
