FREEFLEX heated tubing from Watlow provides a flexible heat-up and transport system for moving fluids in tubing as small as 1⁄32 in. (0.8 mm) inside diameter. These heated tube assemblies are made from polymeric tubing. FREEFLEX heated tubing heats fluids up to 212°F (100°C) and maintains temperature during transfer from a reservoir to a point of use. In some applications, the heated tubing can actually serve as the reservoir for limited volumes of fluid, helping to reduce start-up times. For higher temperatures contact your Watlow representative. Watlow's innovative design places the heating element and sensor directly in contact with the perimeter of the tube to produce efficient, responsive heating and temperature control of the tube contents. The element is evenly wound to ensure reliable, close contact for uniform heating along a portion or the entire length of the line. A flexible, durable jacket covers the wound element and lets the tubing flex and move in a dynamic system. This allows for fluid delivery to multiple locations from a single supply source. In stationary applications, the FREEFLEX heated tube is conveniently routed through available space or around other system components. This saves space and provides for an uncomplicated retrofit in existing systems.
