Masterwatt:heaters mounted on threaded plug
been conceived to satisfy the most different needs in
the heating of liquid substances, both in the industrial
and in the civil applications.
They are designed to be inserted into tubes, basins or
pressurised tanks and they are sunk in direct contact
with the fluid. Thanks to the presence of armoured
electrical heaters, the heat exchange is very effective
and it is possible to design very compact heaters.
These heaters are quite different from the flangemounted
heater: they are normally smaller and their
heating power is lower.
These products are designed by our technical
department on the basis of customer provided
functional requirements. The design takes into
account the physical, chemical and thermodynamic
characteristics of the fluid to be heated, as well as
the operating temperature, the features of the site
and the allowable clearance in the area where the
heater will be installed. The iteration between design
and analysis leads to define:
1. the specific power and the required number of
heating elements (1 or 3)
2. the threaded-plug dimensions
3. the maximum sheath temperature and,
consequently, the safety devices to be used
4. the materials to be used in the construction
5. the dimensional characteristics of the heater
Thanks to the accumulated experience, to the data
collected during in-house testing and to the return
information provided by our customers, we can today
propose the most appropriate materials and solutions
to the customer.
The main characteristics of the heaters are defined in
a technical data sheet, provided with the offer, which
allows the customer verify the main electrical data
and the mechanical interfaces to the plant.
