Uttam Make Vulcanizers are horizontal, circular vessels for curing of rubber articles. These are made in diameters ranging from 800mm to 2400mm and the length 1 meter to 12 meters depending upon the requirement of the users.


PRESSURE RATING : Uttam Vulcanisers are normally designed and built for a working steam pressure of 5 Kg/cm² and are tested hydraulically before despatch for a pressure of 7.5 Kg/cm²

DIRECT/INDIRECT HEATING : For direct steam curing single wall vulcanisers are standard supply, however for indirect curing coil-in-chamber type Vulcanisers can be supplied with cyclonic-fan motor for even temp. in vessel

TYPES OF DOOR : Either swing-bolt type doors with mono-rail type retracting mechanism, sealed against leakage by asbestos ropes or quick-lock type design as shown in picture.

TEMPERATURE INDICATION : Temperature indicator shall be provided.

FORCED AIR CIRCULATION : For hot air curing, forced air circulation fans can be attached on rear side of the vessel to ensure even temperature at all points in the Vulcaniser. These fans are with special water cooled seals.

STANDARD ACCESSORIES : Standard Vulcanisers are supplied with blank flanges for steam, inside batch trolly, bridge-stand, safety valves, Guages etc.
