SH420/SH420F Graphite Digester
SH420/420F Graphite Digester adopts globally advancedhigh-temperatureinfrared radiation heating technology
and microprocessor control platform,accurate temperature control and quick temperature rise. It has two kinds of
temperature rise mode: linear and curve temperature rise mode, and offers 20 digestion programs for control of
temperature rise curves.
Neutralization system is including ternary filtration functions, condensation, neutralization and filtration. The product adopts high-quality anticorrosive Pumps, low noise, strong suction, reduce exhaust emissions, eco-friendly.
Characteristic
* 20 positions enhance working efficiency rapidly.
* Graphite block have longer life after special anti-oxidation processing and heating more uniform.
* Corrosion-resistant design
* It adopts advanced PID temperature control technology,high accuracy heating up to 400°C only 25minutes.
* Multi-protection, Over-current protection, high temperature warning, overload protection.
* It adopts 5.7" color screen, easy for use.
* Standard configuration with waste gas collection hood WD03.
S402 Exhausting System
* Mould design, compact appearance
* Absorption device area is translucence design, easy for inspection and changing
* Suction pressure is adjustable when become negative, to avoid acid gas spilling oremptying
* Anticorrosion vacuum pump, low noise, large suction, reduce wasted gas exhausting and environmental friendly
* Ternary filtration system (water condensation, alkali neutralization and active carbon filtration) ensure perfect neutralization and absorption performance. PTFE anticorrosion pipe design, improve using life
Temperature control model
Program control, curve and linear temperature rise.
Waste gas treatment
Neutralization system has perfect effect of neutralization and absorption performance, can neutralize acid mist and reaction waste gas where from Kjeldahl or other experiments.
Adopt efficiency anticorrosion pump f o r absorption, unique and efficiency absorption device design. It makes contact area expanded with gas/ liquid, perfectl y neutralize acid gas, made operating environment friendly.
