Gas In-Line Heater - ACCUHEAT

As sophistication and demand for process purity increases throughout industries, equipment manufacturers must pave new paths, to provide the tools needed to reach the next technology node. Imtec understands and demonstrates this core value throughout its product lines. With growing demand for heated high purity gasses such as heating nitrogen gas. Imtec has designed and delivered the Accuheat G-Series, a gas in-line heater, for heating a wide range of gases which include:

  • - Ammonia (NH3)
  • - Helium (He)
  • - Argon Heater (Ar)
  • - Hydrogen (H2)
  • - Arsine (AsH3)
  • - Hydrogen Bromide (HBr)
  • - Boron Trichloride (BCl3)
  • - Hydrogen Chloride (HCl)
  • - Carbon Dioxide (CO2)
  • - Nitrogen Heater N2
  • - Carbon Monoxide (CO)
  • - Chlorine (Cl2)
  • - Nitrous Oxide (N2O))
  • - Oxygen (O2))
  • - Disilane (Si2H6)
  • - Sulfur Dioxide (SO2)
  • - Methylsilane (SiH3CH3)
  • - And many more...

With technology and know how gained from over two decades of manufacturing quartz inline fluid heaters. Imtec has designed the Accuheat G-Series to be extremely robust, efficient, and pure. With quartz being the sole material to come in contact with gasses being heated you can be sure that there are no particle adders or contaminates.

In-Line Gas Heater

Extremely reliable, heavy gauge heater elements are affixed to the outer diameter of each quartz tube along with over temperature sensors, creating a truly robust design. The Accuheat G-Series are available in many sizes (single or dual tube) and wattages, contact us for more details.

Efficiency

double wall quartz tube

Ultra high purity gas heating is a challenge. Metals can break down and/or shed particulate, while other materials are inefficient at heat transfer. Imtec has solved this challenge using a unique tube-in-tube design that provides for excellent heat transfer in a ultra-pure, non-metallic flow path. The tube-in-tube design creates a .060” wide flow path that creates intimate contact between the gasses and heated surfaces. This makes a dramatic improvement in efficiency when compared to other designs.

High Flow Rates

The G-series heaters are available in single or dual tube configurations allowing for a wide range of temperature/flow applications. A dual tube configuration allows for high flows, almost a doubling of a single tube configuration.

Flexible Control

Gas heating applications can vary dramatically making the control tricky. The Accuheat G-series offer the ability to monitor/control heater element temp, which can be useful for low flow, intermittent applications.
