CARTRIDGE HEATERS - BOLT HEATERS - BOLTMAX (MID VOLTAGE)

 

BOLTMAX Bolt Heaters

BOLTMAX electrical heaters are provided with a sturdy ergonomic handgrip that lets their inserting into holes that are purposely drilled in bolts. They very rapidly thermally lengthen the bolt, letting the nut be further turned on it, therefore providing the highest torque.

Features
• Sturdy plastic-rubber handgrip with rough anti-slide surface.
• Heavy aluminium fusion painted box for electrical connection.
• Cable fastener especially designed to avoid tearing or cutting of the cable.
• Feeding cable, optional, with silicone rubber sheath, length to be specified.
• Internal insulation: compacted MgO.
• Working temperature in free air: 800 °C with 8 W/cm².
• Construction designed for keeping an excellent linearity in time.

Applications
Turbines, motor heads, shipbuilding, pressure boilers, flanged pressure pipings, civil construction, mechanical and hydraulic presses, molds.
