Series GHE-Ⅱ Interlayer Heating & Circulating Stainless Steel Temperature-Controlled Comparison Laboratory Drum

Ⅰ.Application Scope :
Series GHE-II interlayer heating & circulating stainless steel temperature-controlled comparison laboratory drum is essential laboratory equipment in modern leather-making industry,which is composed of two same type of stainless steel drums used for comparison tests of leathers in small batch and varieties at a time,thus achieving the best processing technology.The equipment is suitable for wet operation in preparation, tanning, neutralizing and dyeing processes ofleather making.


1.The equipment is equipped with the advanced interlayer electric-heating & circulating system.The liquid insidethe drum is totally separated with the heating medium in the interlayer of the drum so that the drum can be heated and maintained at a temperature when it is stationary.It is especially suitable for test at low ratio of liquids.All test date are accurate.The inside of the drum can be cleaned thoroughly so that there will be no any residual liquid and west residue remained.As a result of that,color spot or chromatic difference can be eliminated completely.
2.Speed of the drum is regulated by means of frequency convertor through belts.It has advantages of stable drive and low noise.
3.This equipment is equipped with 2 control systems, 2 driving systems and 2 heating systems. Each drum can be operated separately.
4.The equipment has the timing functions of controlling total working cycle time,forward & backward rotation duration as well as single direction operation.
Each duration can be set up through timer respectively so that the drum can work continuously or interruptedly.
5.Equipped with an intelligent temperature controller,automatic heat,constant-temperature hold and temperature control can be achieved accurately.
6.The observation window is made of fully transparent,high-strength & thermostable toughened glass so that there is no such phenomenon as distoetion dimming.
7.There is cleaning door and dredge through so that wastewater can be discharged into the tough that makes the process clean.
