Feature: Enclosures
Is it just an enclosure? By Chris Lloyd, Managing Director, Spelsberg UK
T
he design and specification of an enclosure can make or break an application. While some projects require a standard
enclosure for quick installation to keep costs down, others rely on a highly- specialised design. Whatever the application, gaining the
right advice on the correct enclosure to meet the requirements is vital.
Just a casing? In one respect, an enclosure is simply a casing used to retain and position electronic/electrical components or equipment, whilst protecting them
from external conditions and intrusion. However, as soon as we begin to consider the items that the enclosure will house, a series of increasingly complex questions arise, starting with where it will be installed and how it will be used. Failure to specify the right enclosure
for use within a given setup can have expensive consequences. Not selecting the right level of functional integrity for protection of the contents in the event of a fire could create an even more serious outcome. When selecting an enclosure,
it’s crucial to be provided with the sufficient level of advice in order to make the right specification, first time.

The first step is usually the enclosure supplier’s telephone and web support; in case of Spelsberg it is called Pro- Active. Technical support operatives ascertain specific needs, to advise on critical decisions on the enclosures’ key features and properties. Alongside understanding the application, engineering expertise will help determine aspects such as the climatic conditions and resistance to weather, temperature and ingress of dust and liquids, as well as the level of impact resistance required. The application could even be coastal or marine use, with challenges relating to corrosion and UV protection, in addition to water ingress.
