Cartridge Heaters-1

ULTRAMAX are a new generation of high wattage electric heating elements, having high power in a limited area and ensuring, all the same, excellent reliability under heavy-duty working conditions. The special technology used in their construction make them the most advanced type of heating element. The nickel chrome wire wrapped around a magnesium oxide core is situated in a peripheral position, with a very thin compressed insulating layer between wire and sheath. This allows efficacious heat exchange, thus maintaining the temperature of the resistance wire at a much lower level compared to other heating elements where the wire is situated in the center. Furthermore, not only do they owe total reliability to the use of advanced technology and precise inspection techniques during manufacture, but also to the use of first-class material from the best LA'ri1 l^"rfc T*1nl v*vt£tti Itvl NQpl ImpfraiLmi ■ lotal atimoc* of migmunt • low cuffioapj cd orwn wjpiAQCfi PTTS crudity mfi—ini uKid* jrm. wttfi orinUdr itrurtiini th»t Over 60,000 models on stock Over 60,000 standard, semi- finished elements are kept on stock, ready to be finished sealing, cable outlet, cable and insulation type, cable length, fittings and various other heating cartridges can usually within 3 working days from order receival.

The compactness and high watt density of Ultramax heaters make it an excellent solution for the heating of liquids. Place the heater as far as possible from the tank walls to favour the highest circulation of liquid by convection. Make sure the heater is always covered with at least 20 mm of Avoid too frequent ON/OFF cycles using a proportional Make sure no powder, rust, lime deposit or other foreign substance pollutes the heater's sheath. To avoid emptying the tank when replacing the used heater, is advisable to use our additional sheaths. If there is risk of liquid's overflowing, or there is...

Cable Options ULTRAMAX heaters can be supplied with flexible cables coming directly out of the cartridge. These are suitable when a highly flexible cable is required also near the head. With this solution, the cartridge head must not exceed the temperature of 260 °C. For higher temperatures, contact our Customer Service. ULTRAMAX cartridges can be supplied with cables protected by a flexible tube of galvanized steel (standard version), or stainless steel (on request). This type of protection is advisable to avoid the cable being smashed, grazed or torn. ULTRAMAX cartridges can be supplied with...
