Accuheat™ Quartz In-Line Gas Heaters

Accuheat Quartz In-Line Gas Heaters


Accuheat™ G-Series gas heaters are robust, efficient, and pure. Quartz is the only material to contact gasses being heated, which prevent particle adders and contaminates. Their reliable, robust design consists of heavy-gauge heater elements affixed to the outer diameter of each quartz tube along with over-temperature sensors. The heaters are available in various sizes, wattages, and in single-tube or double-tube configurations. Single or double-tube configurations allow for a wide range of temperatures and flows. Double-tube configurations allow for high flows, almost a doubling of a single-tube configuration. Flexible controls are also available to monitor and adjust the heater element temperature for low flow, intermittent applications. Power Modulators may be purchased separately to protect the heater against low-no flow conditions.

Tube-in-Tube Quartz Gas Flow Path

The unique tube-in-tube quartz design offers efficient heat transfer in an ultrapure, non-metallic, narrow flow path. The all-quartz flow path eliminates metals that could break down and shed particulates. Quarts offers more efficient heat transfer than other materials. The narrow flow path ensures close contact of gasses to heated surfaces to dramatically improve efficiency compared to other designs.
