cases & enclosures
An enclosure’s purpose is to create an environment in
which electrical equipment is protected from ambient contaminants. Having the door open allows a constant stream of dirty air to be pulled into the enclosure. This will then gather in switchgear/connection points and can cause short circuits or block on-board fans which will result in damage to componentry, reduced life and possible critical component failure. If this course of action is required it can point to the
fact that the cooling equipment currently employed is not adequate for the installation, or it requires some level of maintenance to bring it back into working order. A RiAssure free Cooling Review from Rittal is perfect
in this instance as your local Climate Control expert will perform a short appraisal of your existing equipment, give you honest feedback as to whether the equipment is adequate, and also provide details/quotations for a service contract to suit your ongoing needs.
3) “My EquIPMENT IS CuRRENTly
oPERATING, AND I HAVEN’T SERVICED IT IN MoNTHS/yEARS”
The problem may be “out of sight, out of mind” for now but the longer your cooling equipment is left unchecked, the higher the risk. For example, if a fan unit is in a dusty environment and
the filter mat becomes clogged, this will reduce its effectiveness to cool the electrical equipment within due to a reduced level of air throughput. This in turn can increase the enclosure internal
temperature. As a rule of thumb, for every 10°C you increase your internal temperature, you halve the life of the equipment within and increase the likelihood of an unexpected failure.
4) “I DoN’T HAVE THE MANPoWER/ WE HAVE A CoMPANy WHo DoES THAT WoRK FoR uS”
Many companies that Rittal visits say that they outsource their servicing to a third party, however it is important to question what checks they are performing, given that Rittal has been called onto site because an enclosure is overheating. on one occasion, Rittal asked the customer to speak
with his current service provider to understand what checks were being undertaken, because his cooling units were in quite a state of disrepair. It became clear after a short discussion that they serviced “Air Conditioning” in the offices and did not even look in the factory. obviously, this is not the case for all service providers out
there, however climate control equipment becoming increasingly efficient, while new, sophisticated, cutting-edge technology is launched every year. The only guarantee of the highest level of checks and service will come from engineers who have been trained by the manufacturers about the technology and its detailed workings. Rittal has been manufacturing industry-leading climate
control equipment for 30 years and all of its service staff are highly trained on the whole portfolio to ensure they can remedy your issues. Take the introductory example again and turn the
spotlight onto your business. Everyone has budgets and savings targets to hit, so ask yourself, can you afford not to have correct maintenance in place?

export success for ex enclosures
I
ndEx Enclosures, the Kent-based manufacturer of Hazardous Area and Industrial control gear enclosures has just dispatched the latest consignment of Activated
Isolation, Modulation, Fire & Gas Damper junction boxes bound for the huge Tengiz oilfields of Kazakhstan. The custom-designed ATEX Zone
1 certified and Industrial Standard enclosures, were ordered by North Sea Ventilation (NSV) of Hull. Andrew Sully, NSV’s project
manager, comments, “We originally began working with IndEx Enclosures on this contract back in 2016 leading to the supply of some 3,200 off ATEX- certified and Industrial Standard Junction Box enclosures destined for Kazakhstan which were delivered on time and as agreed. The ventilation systems on the various modules are obviously vital to the whole operation of the facility with the Actuated Dampers regulating the flow of air and extremely important parts of the systems which have to operate in potentially explosive atmospheres. “After the supply of these
enclosures over two years, during which time there had been no delays nor failures of ATEX testing, the scope of our contract was then extended to include another 3,000 off Junction Boxes for field buildings which is just completing. “What steered us towards IndEx
Enclosures was their willingness to design and manufacture non-standard enclosures to our exact specification which includes their population with electrical terminals and supply of tri-
language signage and certification. The products and service has been excellent and we now consider them as a primary preferred source of supply, not only for Kazakhstan, but all similar projects.” Manufactured from 316 Stainless
Steel for its superior corrosion resistance qualities, the 140mm x 140mm enclosures are the latest export success for the company who have developed a high degree of brand recognition and a first class reputation for the design and manufacture of hazardous area control, instrumentation and connection products at their Ashford facility. The company have established a global reputation for customisation and service within the energy, chemical processing, food, pharma and rail sectors with a client base of over 200 active companies. Mark Popple, general manager of
IndEx Enclosures, adds, “We’ve enjoyed a very successful relationship with NSV and look forward to continue to be of service to them. We are slightly unusual in the sector for designing and manufacturing totally in- house which gives us the ability to supply non-standard items for both Hazardous Area and normal Industrial use. Constant investment in our personnel and plant has given us the flexibility to compete with far larger suppliers of enclosures and our clients appreciate our ability to rapidly supply both standard and bespoke items at cost-effective rates.”
