Now, new versions of the VX25 are available in stainless steel and NEMA 4X to enhance corrosion protection and to ensure the equipment within it is shielded from dust, as well as from splashes and jets of water.
The frame structure, doors, panels and the gland plate, as well as all the external parts such as 180° hinges and comfort handle variants, are all made of stainless steel.
While the sheet steel and stainless-steel enclosure types have IP 55 and NEMA 12 protection categories as default, the optional NEMA 4X version with its corresponding IP 66 category protection offers greater protection. This means that the electrical and electronic equipment in the VX25 is protected from dust, water splashes and jets, even in the most demanding of environments.
In order to achieve the high NEMA 4X protection category, the enclosure underwent, among other things, a water jet test. This procedure (“hose-down” test) involved examining any gaps with seals for leaks using a jet of water with a flow rate of over 240 litres per minute for a test period of 40 min/30 s (6 mm/s per seal length). The tests confirmed that no water would penetrate the enclosure, under comparable conditions.
In addition, the tests included a check of the dust protection, corrosion resistance, and protection against damage caused by external ice formation.
The two VX25 enclosure variants have an almost identical design, which means that the interior engineering of the stainless-steel enclosures can also be applied, unchanged, to the NEMA 4X enclosures, saving electrical engineering companies both time and money.
Any requirement for energy-efficient cooling of VX25 stainless steel enclosures can be provided through the new Blue e+ cooling units, which are also available in stainless steel
Paresh Kansara, Product Manager for Enclosures at Rittal says: “The introduction of the stainless steel and NEMA 4X versions further extends the existing VX25 portfolio and ensures that our customers have greater flexibility to meet their customer and project demands, with optimum functionality, simplicity and traceability.
“In addition, our customers can expect to continue to benefit from excellent global service and support associated with the existing VX25 range and the complete Rittal value chain.”
Rittal has a key focus on research and development. An ambitious and exciting product and service roadmap is in place for several new product extensions and innovations in the next few years across Rittal automation systems, enclosures, power and climate control products.
