Cases & enclosures
MechTronic has worked with enclosure manufacturer Spelsberg for over 18 years to provide the heavy-duty industrial housings it needs. Spelsberg includes an in-house design team, as well as a CNC capability, that enables it to tailor customised design requirements to secure MechTronic’s various metering and gauging components. To develop a customised enclosure, typically Spelsberg’s engineers make a site visit, and then create a prototype to test. Given MechTronic’s long relationship with Spelsberg, combined with their own engineering experience, the latest development could take place remotely. Simon Haigh, technical director,
MechTronic explains: “In the case of our pneumatic controller, I provided Claire at Spelsberg with the required internal dimensions, who in turn gave me the relevant format CAD file. I then inserted the relevant drill points, as well as the requirements for printing on the outside of the enclosure. Spelsberg completed the CNC work within two days and returned the protype to us for testing.” Driving down pot-holed farm tracks and remote country lanes in mid-winter means that despite the high volume of entry and exit glands, the enclosures have to resist all weather conditions, as well as vibration.
RUGGED ENCLOSURES “We use Spelsberg enclosures with a high impact resistance and a high IP67 ingress protection rating, which is also maintained at the entry points through cable glands,” says Haigh. “The trucks are often cleaned with a high-pressure jet wash as well, so the enclosures have to be able to withstand this.
Our equipment is also exported to countries including the Ivory Coast and Kenya, so it’s designed to deal with virtually all climates.” Spelsberg constructs its enclosures from polycarbonate, a high-strength plastic, which provides further advantages for MechTronic. “Not only are the polycarbonate enclosures extremely durable, they’re also a lot lighter,” says Haigh. “Ultimately, a lighter truck is more efficient and can carry a higher payload, which increases productivity for the fuel supplier.”
PREMIUM RELIABILITY MechTronic supplies its gauging and metering equipment to between 170 and
210 trucks a year. As well as supplying the home oil heating market, the company also supports the petrol and diesel artic delivery sector, as well as LPG, and uses Spelsberg enclosures throughout. “We are the leading manufacturer of fuel metering systems in the UK, and we work with the best suppliers,” says Haigh. “We do this to maintain a premium product, that is highly effective and reliable, and it has to last. In the UK alone, our systems are fitted to over 1,700 trucks, so we have to know that they are protected. This is why we partner with Spelsberg industrial enclosures.”
