Regulating units ensure proper regulation of heaters

Efficient operation of heaters in various applications usually demands proper regulation and protection of the heater or the heating unit, selection of which is based on the application and the process requirements. There are different ways and types of regulation and control, for different heating requirements. It can be implemented as a simple circuit with contactors, or continuously operating regulation with thyristor controllers, Solid State Relays (SSR) with digital controllers, or PLC.

Vimosa specialises in the design of different kind of regulating units, used for regulating operation of heaters and heating units. It can be carried out via simple capillary thermostats, the mobile control unit, or a special control box. For any heating applications that tend to be more complex, the company designs and manufactures regulating units adapted to the requirements of the system/application.

Capillary tube thermostats use capillary tube with a diaphragm switch on one end, a bulb on the other, and contain a special liquid that expands and contracts at the needed rate, to activate the switch. Regulation with capillary thermostats is perfect for non demanding applications, where response time and high accuracy are not at most importance.

If we want them to work properly and long term, the electric heaters need different sorts of protection. fail-safe overheat protection is best provided by the use of thermal fuse links. A suitable circuit protection ensures safety and helps to avoid down time and unnecessary repairs to the system. The two most common types of overcurrent circuit protection are circuit breakers and fuses. Frost protected heaters are designed to produce a low level of heat output, to combat frost or dampness, and are typically used in workshops, garages, conservatories etc.
