ROTFIL srl Via Praglia 15 -10044 Pianezza (TO) ITALY T. +39-011-9683-111 F. +39-011-9683-225 [email protected] www.rotfil.com 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 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 section: 6 x 6 mm (along heating length). • 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 MΩ. • 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 centerline, with 6x6 mm section: 15 mm. • Important: unheated (round) part at both ends shall not be bent.
