Technical data

General Pointer and Facts

General

Nominal size: The nominal size (inside diameter) is abbreviated as NW or (English) DN, and is

determined by the ﬂ ow quantity and/or the viscosity of the medium. Standard in PTFE (T1...T4) 4....

50 mm, stainless steel (T5) from DN6. Larger dimensions are available on request (see also page

31 transfer - unload hoses).

Hydraulic pressure hoses: The hydraulic pressure hose type is mainly determined by the same

parameters as the nominal size. Added to this is the operational pressure. Other selection criteria

like heat transfers, bending radius or strongly pulsating loads are also important parameters. The

table about the bending radius and operational pressure can be found on page 8. We also heat

special hoses made of Viton, silicone, NBR... that can be supplied on request.

Attention! ➞ The data is deﬁ ned for temperatures from 20...50°C. Increased temperatures

decrease operational pressure loads; please adhere to temperature correction factors.

Connection ﬁ ttings: The selection of the ﬁ ttings is dependent on the nominal size and the opera-

tional pressure load resistance of the hose (light, medium and strong ﬁ ttings range). The standard

range is shown on page 6-7. The heating hose may be ﬁ tted with different ﬁ tting on either side.

Additionally open ends without ﬁ ttings and many types of special type ﬁ ttings (clamp, ﬂ ange, milk

pipe...) are available on request.

Temperature sensor(s): As standard our heating hoses are ﬁ tted with Fe-CuNi (J) thermo ele-

ments. As standard we also apply NiCr-Ni(K) thermo elements and PTC sensors PT100 in 2-wire

connections (3 and 4-wire connections are possible). Other thermo elements types and PTC/NTC

sensors are available on request. Depending on application a variety of sensors can be installed.

The HTI or HTP integral action controller will control the temperature directly at the heating wire

with PTC behaviour.

Control pipes: The assembly of the heating hose can include a variety of electrical connection pipes,

ﬂ exible piping for air, test gas or ﬂ uid media, even in combination. The entry and exit point and

the corresponding connection elements (connections, couplings...) have to be determined. Parallel

pickups enable the connection of additional consumers at the same basic guidelines. Conductor

cross-sections and pipe diameter depend on the connected consumers.

Connection / plug connection: The access line can be taken out from the end cap as described

on page 11. Industrial hoses normally have 1.5 m, analyser connections 3.0 m long connection

pipes. Special models with relegated outputs, different dimensions, separate pies for heating, sen-

sors and control pipes .... can be realised.

The heating hose is ﬁ tted with a connector that matches our control appliances. Basis is the tempera-

ture controller HT43 with a circular connector 6+PE (page 84). Please note that for a non-monitored

operation an additional fuse has to be installed in the heating system (limiter, temperature control

fuse…).

We can also supply devices without connectors for the connection of clamps or the assembly of

customer-speciﬁ ed connectors. We use the connectors of many well-known manufacturers. We can

assemble such parts for you, if you state the pin connections with your order speciﬁ cations.

Heating-up time/safety: Under normal conditions the heating-up time will be between 15 to

30 minutes (enclosed space, approx. 20°C). Before commissioning it has to be ensured that the

medium in the hose and the connection points has reached processing temperature. Bending loads

and plug-ups in the ﬁ tting before reaching the processing temperature may damage the hose.

Before commissioning please read our operational and assembly instructions.
