Durex Industries

DFX electric heat exchangers
DFX electric heat exchangers provide fast, safe, and effective heating of liquids and gases. Unlike traditional electric circulation heaters, the DFX Series heater elements are isolated from the fluid flow path. The heater elements and a coiled, seamless, Type 316 stainless steel flow tube are embedded in a lightweight aluminum casting. This design is said to be ideal for heating deionized water, solvents, sterilization gases, and other substances that are prone to contamination.

Durex thermocouples
Designed for pollution control and process applications, Durex thermocouples can be protected from hostile environments with thermowells or with protection tubes constructed of stainless steel, nickel alloys, ceramic or silicon carbide. Various terminal housings may be used to provide compliance with all NEMA standards, including explosion-proof designs. In addition, these thermocouples are manufactured to meet all applicable ANSI and ASTM specifications. Head-mounted transmitters are available for 4–20-mA signal conversion. Temperature tolerances are standard or special limits-of-error. The thermo-element design can either be single or duplex for multiple outputs from the same point. Elements can be manufactured as large as 8 gauge (.128-in. O.D.) on each leg for long service life.
