*The 7⁄8", 13⁄8" and 17⁄8" hose sizes are only suitable for use with PTFE lined sanitary clamp (or triclover) end fittings and PTFE lined I-Line end fittings.
** The maximum working pressure (MWP) of a hose assembly is limited to the lowest of the MWP’s of either of the two end fittings, or of the hose itself as listed above. The MWP of the hose reduces as the operating temperature increases, consult Aflex Hose for guidance.
Note: 21⁄2" & 3" tube only (TO grade) cannot be ordered as an assembly.

Purpose
For use in applications where the temperature of the process fluid must be regulated as it passes through the hose. In some applications, an additional ‘melt out’ facility may also be required.
Description
The heating element comprises self-regulating element spirally wrapped around the hose assembly. Self-regulating elements may require a sensor and controller if a specific maintain temperature is required. Please consult Aflex Hose for clarification. The power leads and (if applicable) temperature sensor leads emerge from the hose assembly at one end, through glands and conduits. The thermal insulation is foam rubber, silicone foam rubber. The outer cover may be a polypropylene braid or SS wire braid with a blue or black EPDM rubber cover.
Design
Each hose is custom designed and built. Application details must be supplied by filling in an “ETH Hose Questionnaire”, available from the website. Generally, for hazardous areas, particularly “Zone 1”, the Self-Regulating type of heating element is employed, with or without a temperature sensor and control, and flameproof glands and conduit are also required. The watts per metre of the heating element, the pitch of the spiral on the hose, and the thickness of the thermal insulation are all calculated in accordance with established formulae to give the required maintained temperature.
Specifications
As for Bioflex Ultra GP, SS in Specifications, except that the minimum bend radius is tripled and the outside diameter and weight are significantly increased in line with the particular design. The maximum length of a CH/ETH hose is 10m (33ft).
Limitations
1” PTFE lined PN10 flange spigots on heated hoses can only have a maximum flare diameter of 50mm, not 63mm. If the hose is “hanging”, straight or at 90˚, under its own weight, special construction is required, so advise Aflex Hose accordingly. Minimum ETH Hose assembly length, when collars are used 1mtr.
