Robuschi extends Robox blower package
R
obuschi has extended its innovative Robox blower package range to now cover a 200-kW model. The revolutionary Robox package provides one low-pressure solution for most applications in wastewater treatment and industrial environments, by offering both rotary lobe and screw technologies in a single enclosure, so owners and operators can choose the blower technology that’s the most suitable for them.
The solution is ideally suited to blower applications in the wastewater treatment and industrial sectors. For wastewater treatment plants, the Robox package can provide reliable low-pressure air for processes such as aeration, back washing, sand filtration and desalinization. For industrial facilities, the system can be used for the pneumatic conveying of granular, powdered and sensitive bulk materials, lime cement fluidization, and many other applications requiring low-pressure air. The difference between lobe and screw technology in the Robox enclosure is reduced to just a few components, making it a simple, straight-forward process to switch from one blower technology to another. As a result, decision makers can select the technology that will best help them improve energy efficiency levels and reduce on-going costs, depending on a site’s industrial air demands. The latest 200 kW model of the Robox blower package is available with a pressure range up to 1,000 mbar (g) and volume flow of up to 5,900 m3/hr. The system also features a horizontal axis with a compact suction silencer, ensuring a reduced noise level.
Protection Devices (SPD) becoming increasingly common in installations it is surely time that there was an accepted test to confirm their efficacy.” “The manufacturers say that they are 100 per cent tested before they leave the factory, but it is not hugely reassuring to the installer whose insurance take on liability once they supply and install the SPD. Furthermore we know they deteriorate with repeated overvoltage episodes; so how should it be tested as it ages? We know that electrical engineers are not going to want to buy the complex and expensive testers the SPD industry sells. They are going to want an additional function on their existing tester”
Tickling the SPD nerve B
rendan Beaver, the manager of Metrel UK Ltd said, “With Surge
“Metrel multi-function testers have for more than 10 years offered a ramp facility on the insulation test which gives the ability to test varistors and some SPDs in the field. Maybe it is time that the powers that be recommend a test protocol which could be incorporated in all multi-function testers!”
ECA responds to Queen’s Speech “skills guarantee” he
number of apprentices fell in almost a quarter of
T
electrotechnical and engineering services firms since the beginning of 2021. The figure comes from an ECA business survey carried out earlier in May. In the light of this finding, ECA applauded yesterday’s confirmation of a ‘lifetime skills guarantee’ in England and urged engineering services employers to make the most of all the recruitment options now available to them. While welcoming the Skills and Post 16 Education Bill announced in the Queen’s Speech, the trade body sounded a note of caution. Andrew Eldred, ECA Director of Employment and Skills, said: “The current uncertainty facing firms from many directions is the root cause of falling apprentice numbers. No amount of incentives will change employers’ minds if the outlook remains volatile. However, the ‘lifetime skills guarantee’ opens up another important option for employers looking to support skills development. Training routes for career changers or unqualified but experienced workers – which employers or individuals themselves have had to fund before – will now attract Government support.” The ECA survey of 700 electrotechnical and engineering services firms revealed 24 per cent fewer firms employed apprentices in Q2 2021 than in Q1. Over a third (34 per cent) employed fewer subcontractors. And 22 per cent hired fewer direct employees.
The ‘lifetime skills guarantee’ incorporates industry recognised qualifications, as recommended to Government by the Electrotechnical Skills Partnership (TESP). ECA is a leading member of TESP and advises member- businesses on appropriate training routes. Andrew Eldred added, “A recovery in apprenticeship recruitment is vital if businesses are to benefit from new growth opportunities and competence requirements – but nurturing older candidates, including those switching jobs and sectors, is another crucial part of the mix.”
