Bolt-Lengthening Electrical Heaters (middle voltage) Electrical bolt heaters are designed to be inserted 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.

BOLTMAX Middle-Voltage Bolt Heaters • 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. Turbines, motor heads, shipbuilding, pressure boilers, flanged pressure pipings, civil construction, mechanical...

BOLTFAST Low-Voltage Bolt Heaters BOLTFAST heaters are a practical and reliable tool and are mainly used for the extension of bolts and rods during the assembly of turbines, nuclear plants, presses, building construction, pressure boilers, etc. Due to their quick action the BOLTFAST heaters guarantee precision and high productivity. They are essential when fast action and a perfect thermodynamic action are required. Insulation by means of compressed borum nitrite raises the speed of heat transmission and allows excellent insulation even with temperatures above 1000 °C. The strong and...
