Accuheat™ chemical in-line heaters consist of ultrapure quartz tubes, wrapped in an Inconel heater element that provides even, conductive heat over the entire area. Alumina Silica insulation is tightly packed to minimize heat loss and the PTFE housing offers chemical resistance and a low surface temperature. Temperature sensors and leak detection devices are included within the housing to ensure safe and efficient operation. For the ultimate in high purity, Accuheat™ quartz heaters can be made of synthetic quartz materials with even lower trace element levels than standard semiconductor-grade materials.
Quartz in-line heaters can be used in many applications requiring heating of high purity process fluids such as acids and cleaning solutions. The traditional application uses the acid in-line heater as part of the recirculation loop, either as the sole heat source or in combination with a heated quartz tank for faster heat up times and better control. Below you will see the typical installations of quartz chemical heaters:
Single Pass Point of Use
Conductive Heating Element
Many commonly-used chemistries do not readily absorb infrared heat, making infrared heaters a poor choice for some processes. Heaters employing this technology often have maintenance issues and require cooling or a purge to prevent overheating failures. IMTEC chose a special conductive heater element to reduce maintenance and overall cost of ownership.
Quartz Fluid Path
Quartz performs well with almost any chemistry including solvents. Since the fluid path is quartz, IMTEC’s in line units can also be used as high-purity solvent heaters. Ultrapure synthetic quartz materials are also available.
IMTEC’s proprietary power modulator ensures that the exact amount of heat for any process is applied- no more, no less. During initial heat-up, the rate of heat transfer gradually decreases with time. When the rate of heat transfer bottoms out, the power modulator turns the heater off, allowing the heat built up in the quartz to disperse into the liquid.
Turning off the heater when it isn’t needed means that there is no wasted energy, and no undue stress on components caused by over-heating. IMTEC’s proprietary technology ensures minimal heat-up times with an efficient use of energy for any application.
