Clear Tubing

For most applications, clear tubing is the preferred choice. Because clear quartz has a much higher transmission rate of infrared energy than translucent quartz, it also has a higher radiant efficiency.

In addition, clear quartz provides for a faster response time and generates a shorter wavelength than translucent quartz. It is available in a larger number of diameter options and can operate at higher temperatures — namely up to 1800°F (982°C).

Translucent Tubing

The main advantages of translucent tubing are low pricing, longer wavelength, and a non-exposed heating element. Some customers prefer a translucent tube for their applications for the aesthetic reason that the heating element is concealed within the tube.

Tubing Diameter

Clear- 3/8", 1/2", 5/8", 7/8", and 1" | Translucent- 3/8", 1/2", and 5/8".
The tubing diameter is commonly determined by matching the existing tube diameter or by basing it on the specifics of the tube's design using aspects such as wattage, voltage, and heated tube length. The goal is to maintain a low coil watt density for a long tube life. Coil watt density should not be confused with watts per lineal inch, which is the total wattage divided by the heated length. Coil watt density is the watt density on the coil itself. A good design for long element life is attained by having a low coil watt density. Sometimes this is accomplished by changing the tube voltage, while other times the tube's diameter is increased.
