PIROMAX Sealed-Band Nozzle Heaters Features PIROMAX nozzle heaters are a top-quality product, result or our unique high-technology. They are completely against external agents such as melted plastics. PIROMAX are a rugged product that resists very well to wearing and shocks. Their high watt-density per square centimeter allows a fast and safe reaching of the required working temperature. During manufacturing, the heaters are submitted to extremely high pressure that ensures high insulation, excellent thermal exchange, lack of internal voids, perfectly smooth contact area for an optimum and uniform heat transfer to every part of the nozzle. The inner profile is perfectly round, providing a perfect coupling with the nozzle. Size of the connecting cap is minimal, giving extremely limited overall dimensions. Power connection is performed by a metal braided cable, standard length 1 m, with two nickel power leads plus a galvanized-copper ground lead. Technical data • Brass tubular sheath (also available in stainless steel, for corrosive materials such as PVC). • Standard power density: brass 4.5 W/cm2, stainless steel 7 W/cm2. • Tear-resistant connection of power cable. • Dielectric strength: 1500 V. • Perfect roundness. • Extremely small connecting cap.

Connection Options Standard connection (stock models) Fitting Instructions • A 4-mm exagonal wrench shall be used. • There shall be no gap between nozzle and heater (loose-fitting heaters shall not be installed). • After initial heating-up, clamping screws should be re-tightened . • Repeated bending of the cable near its junction into the heaters should be avoided. • Plastic material on the heater's surface must be removed by raising the temperature of the material. Avoid hammering or tearing to clean off attached plastics. 1 All PIROMAX heaters can be supplied with a built-in J-type...

PIROMAX Stainless-Steel Heaters For brass models, please see the previous page. Standard models are with 45° axial connection and 1 m-long metal-braided cable, inclusive of ground conductor.

PIROSLIM extra-slim Nozzle Heaters These heaters are not sealed against liquids. Please choose Piromax (see above) for sealed construction. Standard models are in stainless steel, with 1m-long metal-braided cable, inclusive of ground conductor.

MgO-insulated Nozzle Heaters Their compacted, high-purity MgO insulation provides high electrical insulation and thermal conduction. The AISI 304 stainless steel sheath makes these heaters corrosion-resistant and fully sealed against water, oil, melted plastics. The smooth inner surface and perfect roundness provide high, fast and uniform heat transfer to the whole Construction features allow high power densities (up to 20 W/cm2) and high working temperatures (up to 500 °C constant, or 700 °C for brief moments). Extremely small connection tube connecting to a high-temperature, flexible,...
