In times of uncertainty, make the most of your assets
Any change or upheaval that impacts on a company’s trading environment brings with it challenges, but also opportunities. Karl Lycett of Rittall looks at the role of enclosure climate control.
It’s safe to say that there is a great deal of uncertainty at the moment. In these circumstances, the best thing that businesses can do is protect their existing assets. It's fundamentally important to ensure that all assets perform at an optimum level during their entire service life, and for an organisation to continue its journey towards increased efficiency and reliability so that it can remain competitive in a changing marketplace.
In the industrial space, a company’s lifeblood is its machinery and all machinery has critical components. It’s imperative that electrical equipment is housed within a protective environment, to ensure it operates to its full potential. A protective environment takes the form of both high quality enclosures and correctly prescribed climate control equipment. The two items work together to safeguard your equipment from the following:
Prolonged high internal temperatures reduce the lifespan of your equipment. This will mean an increased chance of unplanned breakdowns, increased costs and reduced production output. Furthermore, your equipment cannot work at 100% output once its maximum operating temperature has been exceeded, which means you will experience an overall reduction in your machine’s efficiency. To prevent high temperatures being reached within the enclosure, correctly sized enclosure cooling products should be installed. This could be fans and filters, cooling units or air-to-water heat exchangers, dependant on both the amount of heat produced by the electrical equipment and the ambient temperature in the environment.
Equipment needs protecting from low temperatures as much as high ones. In winter, when ambient temperatures drop, any equipment that has been idle over the weekend can be damaged as soon as it’s turned on from cold. In addition, motors or compressors can experience problems when oil contained within sealed systems begins to increase in viscosity, damaging the seals/components.
To prevent this happening, you should fit a correctly sized enclosure heater inside the enclosure. When connected to a thermostat, the heater will maintain an acceptable minimum temperature preventing any damage to electrical equipment caused when the low temperature minimum is exceeded.
Condensate can be a real issue when it forms within the enclosure and on critical equipment in high humidity environments. Condensate poses a real safety risk to the electrical devices and can cause catastrophic failure if left unchecked. You can combat this problem by using a high quality industrial enclosure with a minimum of an IP54 seal to prevent humid air from constantly entering the enclosure. This can be combined with a cooling unit featuring an integrated condensate evaporator.
Many industries suffer from dusty or dirty environments, which can impact on electrical equipment and its optimum performance. Contaminants can attack and corrode (or worse) the wires and electrical connections within your enclosure, which in turn can cause excess heat and/or a panel fire.
In highly contaminated environments, the best advice is to use a cooling product which does not allow dirty ambient air to constantly enter the enclosure, so fans and filters are a no-no. Air-to-air or air-to-water heat exchangers and cooling units are best solutions, dependant on the heat load as they will only treat the small pocket of air within the enclosure, but they will also reduce the level of contaminants entering the space.
