CARTRIDGE HEATERS - OPTIONS & ACCESSORIES - SPECIAL FEATURES

 
S28 ULTRAMAX WITH BUILT-IN THERMOSTAT
  These cartridge heaters with built-in thermostats are the ideal solution when you need an extremely compact system for heating while also controlling the temperature. They are especially suitable for heating liquids and especially when you need an effective safety control against exceeding the maximum allowed temperature. The thermostat has a non-adjustable pre-setting.
S29 ULTRAMAX WITH CONTACTS FOR SLIDING SUPPLY
  These cartridge heaters are suitable for heating rotating cylinders
S30 ULTRAMAX WITH TEFLON BUSHING
  All Ultramax cartridges can be supplied with head bushing in teflon instead of ceramic material. The teflon bushing offers moderate protection from humidity and excellent protection against mechanical shocks.
S31 ULTRAMAX WITH DIFFERENTIATED TEMPERATURE SECTIONS OR NON-HEATING SECTIONS
  Ultramax heaters can be supplied with differentiated wattage density heating sections and with cold sections. Contact our Customer Service.
S32 ULTRAMAX WITH INDIVIDUAL TEMPERATURE CONTROL AREAS
  Ultramax heaters with individual temperature control areas that allow you to have a diversified temperature control on predetermined areas of the system to be heated. The areas can have constant or diversified wattage and length, with internal or external thermocouples. When you order, specify accurately the diameter, length, wattage and voltage, the position of the areas and the thermocouples. Our technical office will rapidly conduct a feasibility study.
