|Vulstar® cartridges are used to heat metal like moulds, dies, plates and bolts or liquid. They can be provided with a thermocouple .||VULSTAR® cartridge with thermocouple
|VULSTAR® must be inserted in a drilling with an H7 allowance, pre-lubricated with an anti-corrosion product to facilitate installation and removal.
Where possible, this drilling must be extended by a hole through the other side for insertion of an extractor. Length L must be fully in contact with the medium to be heated. The high heat flow of VULSTAR® cartridges requires efficient temperature control with a probe (usually a J- or K-type thermocouple) installed close to the heating section.
