Templine

If a medium-carrying link must be movable and easily extended or replaced,
hoses and not rigid pipes are the practical choice for that link. Moreover,
to prevent heat loss in the carried medium, a combination of hose and
electric heating is the ideal solution.
This combination is offered by the novel templine heated-hose system from
Masterflex AG. This innovative design additionally leads to a significant
reduction in energy consumption! Development of the Masterflex AG templine
product series was the outcome of the Company's long expertise in the field
of innovative High-Tech Hose Systems and of ongoing dialogue with customers.
The heart of this new development is a medium hose combined with an
economically efficient heating system and a completely new design. By virtue
of their design, templine heated hoses have specific advantages for the user
compared with conventional heated-hose systems. The latter, electrically
heated by means of conventional heating elements derived from the "trace
heating" model are always only a compromise. Such heating systems cannot
always match operators' individual requirements. Awareness of this inspired
Masterflex AG to develop an alternative approach and ultimately a new heated
hose system.

Applications
The number of individual applications in process
engineering is immense. Electrically heated hose systems are found for
example in:
- chemical and petrochemical plants for grease and oil liquefaction, for
conveying chemicals in movable plant units, in plants handling bulk
materials (decondensation) and liquids and much else
- in the motor industry in analysis systems for monitoring exhaust gases
in mechanical engineering, e.g. for heating hydraulic fluid and in
book-binding machines
- in adhesive technology, e.g. in labelling machines and machines for
laminating wood and plastic
- in automation, e.g. in production robots in the motor industry (painting,
bonding of bodywork parts etc.)
- in the food and allied industries, e.g. for conveying fats, liquid sugar,
cocoa butter
- in special applications, e.g. equipping of vehicles during exhaust-gas
clean-up

Heated Hoses

Wherever media must be kept flowable by temperature maintenance and a
flexible link between inlet and outlet is required, electrically heated
hoses are the ideal solution. templine heated hoses are flexible in two
senses:
- high mechanical flexibility due to the concentric layout of the heating
system
- four heating cables = four circuits = four different heating capacities
- Electrical interconnection of these heating cables determines the heating
capacity of the templine heated hose. It can vary between 50% and 200%.
templine functional principle
The medium-carrying hose inside is covered by a temperature-resistant
braiding. The four heating cables are woven into and fixed inside. They
produce on the hose surface a uniform heat which can be precisely monitored
at all times. The heating conductors consist of various metal alloys with
different resistances. Designed as highly flexible fine-wired conductors,
they follow almost every movement.
Different combinations of the heating cables allow to influence on the
heating capacity of the hose.

templine-R temperature controller
The templine-R complements the heated hose, making it an
integrated, ready-for-use system. The electronics monitor the temperature of
the medium in conjunction with a sensor on the surface of the
medium-carrying hose. They are installed at the factory in the heated hose's
connection housing.

templine-B temperature limiter
The temperature controller can be combined with the
templine-B temperature limiter inside the adaptor enclosure. The limit value
can be individually chosen according to process requirements as with the
temperature controller.

templine-A connecting piece
The templine-A heated-hose system has been designed for
the connection between external supply/control and heated hose. The
temperature sensor lines are integral components of the flexible supply
cable.
