GZGS4 drum consists of several drums which have the same specification. This drum adopts isolating pump heat circulation technology and is effective in transmitting heat into drum by heating the media in the inter-bed which prevents the leather against contamination by separating the water from getting in touch with the leather liquid and ensures thorough discharge of water without residue.It works well in heating and temperature-keeping no matter with or without water in drum,even the drum stops.

We adopt intelligent controller or PLC touch screen together with frequency conversion function to make it possible for automatic rotation in positive and reverse direction,intermittent shutdown,single-direction rotation,forward/backward inching operation and so on. The chain & chain wheel we adopt,being smooth with low vibration and low noise in driving,can stand long-term operation with low frequency of maintenance.
