Square Cross-Section Tubular Heaters
Features
The most advanced technological solution for injection manifold heating.
The square cross-section of the heating length results in a very high level of heat exchange.
Installation is very easy: no fixing is needed to hold the heater in its seat. It is simply necessary to work a square cross-section groove where to fit and press-down the heater in its final position.
Square Cross-Section Heaters will guarantee both the perfect stability in the groove and the perfect contact and heat transmission on three sides of the heater.
Technical Data
• Cross sections: 6 x 6 mm (or 8 x 8 mm, special).
• Tolerance on cross section sides: ± 0.15 mm.
• Tolerance on length: ± 5 mm for lengths up to 250 mm, ± 2 % for lengths over 250 mm.
• Tolerance on the length of unheated parts, at each end of the heater: ± 5 mm.
• Tolerance on power: +5%/-10%.
• Electrical strength: 1500 V.
• Electrical insulation, when cold, with 1000 Vcc: > 10 MOhm.
• Leakage current, when cold: < 0.1 mA.
• Maximum working temperature (external sheath): 750 °C.
• Sheath material: AISI 321 stainless steel.
• Minimum bending radius to the heater's axis, with 6x6 mm section: 15 mm.
• Minimum bending radius to the heater's axis, with 8x8 mm section: 20 mm.
• Important: unheated (round) part at both ends shall not be bent.
