Sheath heater - Import export

Square cartridge heaters are used where much power has to be installed near the surface of a tool, e.g. in cutting knives, sealing stations or hot plates. With a soft, malleable condition in stainless steel or nickel sheath square cartridge heaters can easily be pressed into common milled rectangular grooves. Apart from the advantageous heat transfer over ¾ of the sheath, it is not necessary to cement or cast in the heater which is imperative for round cartridge heaters. Unlike tubular heaters which are also available in square sections (see chapter Flexible Heating Pipes), the square cartridge heaters have the termination on one side and can be loaded with 16W/cm² (2.5W/in²) due to their special inside construction.

The Freek heat transfer nozzle heater type especially addresses manufacturers and users who operated their hotrunner nozzles with cast-in heaters in the past and would like to stick to their engineering know-how without paying the high price of this former heater design. The standard material of our patent pending Freek heat transfer alternative is brass, with or without coating, basically with a slit. Characteristics of our HotMicroCoil nozzle heaters sheathed by a reflection tube are easy mounting and variable heat distribution. Because of its direct touch and toleranced fit, the heater allows a very good heat transmission to the nozzle. In all our HotMicroCoils with reflection tube the assembly of a thermocouple is possible and recommended for bigger diameters and power. Also most common nozzle heater solutions are HotMicrocoil heating elements with clamp bands with diverse locking mechanisms.

Ceramic Pellet Igniter Information Ceramic Boiler Ignition Igniter surface can reach a permanent working temperature above 900℃;Since air can through and around inside and outside of the heater tube. Heat can be transferred from both inside and outside of ther heater element. Igniting wood chips, firewood, coal bricks or other biomass fuel.
