5.3. Cooling the Vulcanizer
Safety: The cooling water may discharge from the platen initially as steam creating a burning hazard. Ensure
the cooling water discharge is not directed at any person or injury could result.
1. When the cure time has been completed and the temperature controllers are switched to the off position (0), turn
on the water supply to cool the upper and lower platens. Leave the power supply connected to temperature
control panel so the platen temperature can be monitored.
2. When the platens have cooled to an acceptable temperature, the cooling water can be turned off. A typical cool
down temperature for a good splice result and safe handling of the belt without the risk of a burn is 150°F
(65°C).
3. The water must be blown out with air before the platens are reheated. Water remaining in the cooling channels
will reduce platen temperature uniformity, increase the heat-up time and may cause the elements to overheat.
Important: If water remains in the platens and the vulcanizer is stored at temperatures below freezing the platens
may be severely damaged.
Tip: The standard cooling hoses and fittings on the Pro and Solo vulcanizer are of the highest quality and have been
selected for their durability and their ability to cool the platens quickly with a minimal amount of water. The
passages in the hoses and fittings may become restricted if there is any solid matter in the cooling water, and this
will affect the cooling rate. Always use clean water for cooling and clean the fittings if the cooling time becomes
excessive.
5.4. Depressurize
1. To depressurize the vulcanizer, turn the safety relief valve toggle on the air control so it is in line with the valve.
