Atlas Copco Rental assists temporary hospital in Italy

Fiera Milano is home to some of the most prestigious exhibitions in the world. But, with all events canceled right now, the space is still being put to good use. A new hospital, designed specifically to treat patients with Covid-19 is being set up.

The “Fiera” Hospital was commissioned by the Lombardy Region (Italy) and is a full-fledged hospital.

When finished, the facility will have more than 400 intensive care units. Once operational, it is expected that 500 nurses and 200 medical professionals will be working and treating patients here, that will come from all over Italy.

The temporary hospital is a source of inspiration and hope, as well as determination.

The Italian government is also considering to replicate what was done here in Milan, and build more temporary intensive care facilities in the center and south of Italy. Regions which are also greatly affected by the Coronavirus pandemic.

For an indefinite period of time, our GA75 VSD+ FF will be a vital part of providing the hospital’s Medical Gas Supply. These systems typically include oxygen, nitrogen, carbon dioxide, nitrous oxide, etc.

Temporary solution for temporary site

We were able to surpass our customer’s expectations thanks to the high efficiency of our equipment.

The GA75 VSD+ FF is capable of providing a maximum flow of 956,88 m³/h at bar. It is equipped with a Variable Speed Drive+, a powerful motor and has a compact footprint.

The GA’s Variable Speed Drive+ (VSD+) technology closely matches the air demand by automatically adjusting the motor speed. Combined with the innovative design of the iPM (Permanent Magnet) motor, this results in substantial energy savings. Even when it is on-site only temporarily, you can still expect the most sustainable solution. Besides that, the GA series is ISO 9001, ISO 14001 and ISO 1217 compliant.

Atlas Copco Rental Russia keeps air oil-free at sub-zero temperature

From extreme temperatures, both high and low, and the most remote locations, our equipment can be found all over the world. In this case, working conditions were pretty cold, to say the least. Gloves: check. Scarf: check. Winter coat x 2: check. Here we go!

Our client specializes in construction services in the oil and gas industry. When a section of pipeline needed repairs and partial replacement in Northern Russia, we provided Atlas Copco Rental equipment that was capable of working in sub-zero temperatures as well as meet all expectations. Working parameters ranged from 10 bar to a potential increase of up to 80 bar, so we came up with a unique solution that was up for the task, every step of the way.

  • 100% oil-free air PTS 916 compressor
  • CD41 dryer
  • Nitrogen generator
  • 4 high-pressure and diesel-driven XRVS compressors with different specifications

Before the pipeline can be used again, a mandatory integrity check has to be performed. In this case, it was possible to perform a hydrotest. Water is used to put the section of pipeline under extreme pressure, far higher than the operating pressure, and make sure it is compliant with all applicable rules and regulations. In order to perform the test, a constant supply of water is required. Nearby water supply was too limited and would have had too big of an environmental impact when these would have been used. So a secondary pipeline, of around 2 kilometers was then constructed to reach a small river. Because it was winter, you can imagine this came with its own challenges. After the hydrotest was successfully completed, the pipeline needed to be dried and cleared of any remaining air, debris. This is where our high-pressure compressors and boosters come in. Usually after dewatering a pipeline, some water remains in the pipes. Dry air goes under pressure into the pipes to absorb the remaining water in the pipeline. Then nitrogen purges the pipelines of all remaining air. These procedures are essential. Not only do they displace the oxygen, but they also delay oxidation and avoid explosions by not allowing air and natural gas to mix in dangerous concentrations. Nitrogen generators with different flows and purities are matched with compressors to reach the required nitrogen pressure and flow. Soon after passing all tests, the pipeline was up and running again!

Getting to the core: faster drilling and reduced fuel costs with Rand-Air’s new DrillAir compressors

In a first for Rand-Air, the company has acquired Atlas Copco DrillAir Y1260 variable high pressure (21 to 35 bar) compressors.

This new technology – from the world’s leading manufacturer of drilling equipment – has been scientifically designed around pressure and flow for a wide range of high-capacity drilling applications.

These two new units are ideally suited for applications such as mineral exploration drilling, geothermal drilling, construction and blast hole drilling; as well as for services such as aerated drilling and the drilling of wells.

“At Rand-Air, we constantly strive to exceed customer expectations. And therefore, for our drilling customers, choosing the right compressor to match hole depth and hammer size is critical to their success,” says Rand-Air Fleet Manager Craig Swart.

“With these two new compressors, our mining customers can choose the right compressor for their core business; and have the flexibility to adapt to changes in well depth and hammer size for any custom application,” Swart points out.

He adds that DrillAir compressors can achieve maximum air flow at any pressure, as the relationship between pressure and flow is optimised, thereby creating the ideal combination of these two variables to improve drilling efficiency through the most efficient use of compressed air – and ultimately, dramatically reducing fuel costs.

What sets the two new DrillAir compressors apart is their advanced PACE and DrillAir AirXpert technologies, which are simple to use and place drill operators firmly in control. PACE (Pressure-Assisted through Cognitive Electronics) is a dynamic optimisation feature, which allows the user to tap into the compressor’s electric engine to control pressure and flow.

Being able to match flow and pressure to their application requirements now eliminates the need to have two separate machines.

DrillAir AirXpert furthermore offers up to 30% improved drilling speeds. This performance management system includes software (Dynamic Flow Boost, Dynamic Control and XPR), as well as a LED hardware controller (Xc4003), electronically controlled inlet valve and a variable minimum pressure valve.

The Dynamic Flow Boost provides up to 4 m³ a minute additional flow when flashing and during drill stem refills. In addition, Dynamic Flow Boost gives 10% more flow at lower working pressure for large diameter drilling. The key benefits include quicker flushing, faster drill stem refill, and a shorter time to complete drilling.

“Atlas Copco’s XPR (Extended Pressure Range) extends the working pressure range whilst setting it as low as 21 bar. In addition, the FuelXpert system ensures fuel efficiency and partial load with an additional fuel filter for better engine protection,” he explains.

“The combination of DrillAir AirXpert technology, the Atlas Copco screw element and the Cummins Stage III engine provides high efficiency for a wide range of pressure and flow settings,” Swart adds.

With its 500-hour service intervals, Rand-Air’s new DrillAir compressors offer customers trouble-free service, quick and simple maintenance and low operational costs. The machines’ centralised drain and air filtration systems facilitate easy servicing; while the design of the new oil separator system reduces maintenance time by over an hour. A dedicated service door allows for convenient oil level observation and oil filling. A three-layer coating on the body of the machine offers an extended life of corrosion-free service, further contributing to lower operational costs.

“Our new DrillAir compressors have been chosen for their robustness, and the fact that they are therefore well-suited for use in remote and harsh environments, where support is sometimes hard to access,” concludes Swart.

Rand-Air temporary generator hire a ‘power of good’ for mining companies

Many South Africans have recently experienced the frustration of mains power outages. While for the private citizen, the lack of electricity for an extended period is an inconvenience, for companies such as mining operations the consequences are much more serious.

In renting generators to mines, there are two aspects to consider. First of all, there is the rental of ad hoc temporary power and secondly, and possibly more crucial, is the rental generators for mine plant shutdowns.

Mining companies, in particular, with the vast sums of capital often invested in them cannot afford production downtime. Rand-Air is able to respond to such crises with high-quality rental generators and the technical support to ensure an uninterrupted flow of power. The company’s range of generators runs from 20 kVA models right up to 1100 kVA units. All run at 50 Hz but can be adjusted to 60 Hz on request. The power supply can either be single-phase 220 V or three-phase 380 V.

“Importantly, our generators are supplied with all accessories needed for immediate operation,” explains Rand-Air Fleet Manager Craig Swart. This includes distribution boards, cables, joiner boxes, COC kits and transformers if necessary.

“If required, Rand-Air is able to advise its customers on the capacity of the generator they need,” he says.

What are particularly useful are the Change over Contactor (COC) kits. These are invaluable when a customer needs a generator to be on standby and start supplying electricity automatically should mains AC power fail. In order to use a COC kit, the generator needs to have an Automatic Mains Failure (AMF) feature.

Rand-Air generators are mounted on trailers (except for the TwinPower which is containerised) and, today, many have distribution boards mounted on the trailer as well, a factor which simplifies the use of the unit. Being trailer mounted, the generators can be taken right to the point where the power is actually needed.

Innovation has always been a hallmark of Atlas Copco. As an example, to this end, Rand-Air has purchased four Atlas Copco TwinPower generators, two 550 kVA generators being installed in each container.

This containerised generator solution gives a very compact footprint, unrivalled versatility, optimised performance and excellent fuel economy in demanding modular power plant (MPP) applications. In addition, the two modules inside the container can be synchronised so that it is possible to supply either 1100 kVA or 550 kVA – a versatile and portable cost- and fuel-saving option for the customer.

“Many of our mining customers prefer to have one self-contained unit on site, as opposed to two individual 550 kVA generators in sync,” explains Swart. The footprint of the container is smaller than two individual 550 kVA generators; and having the generators in containers protects them against extreme weather conditions.

From time to time, mines need to shut down their processing plant for an extended period of planned maintenance in order to avoid un-scheduled shutdowns. With these shutdowns, on occasion, mines use the services of hundreds of subcontractors, all of whom need temporary power. Every day a mine plant is out of operation, the financial losses are considerable, so all equipment on site has to be absolutely reliable and well supported. As Rand-Air sources its generation equipment from world leading manufacturer Atlas Copco, reliability is not an issue. Combined with Rand-Air’s superb service, this is a winning combination.

“Naturally, before any equipment item goes on to site it scrupulously checked by our technicians to ensure no costly breakdowns or downtime ensues,” Swart continues.

“For us at Rand-Air, mine shutdowns, while they are challenging, are also very exciting as they give us the opportunity to show what our company is capable of,” he explains.

“The achievement of finding 50,000 cfm of compressed air for a customer at short notice and getting it safely to site on time is a satisfying and rewarding experience both for ourselves and, ultimately, for our customers,” Swart concludes.

Whether portable diesel or stationary electric, for every application Rand-Air has a compressor to blow you away

In its 46 years of operation, Rand-Air has built up an enviable reputation in the mining industry for the quality of its compressors and the excellence of its service. The company supplies either portable diesel compressors or stationary electric compressors, each of which have particular applications. All Rand-Air compressors use screw compression elements to produce compressed air.

“In mining, industry and manufacturing, compressed air is frequently absolutely essential,” explains Rand-Air Fleet Manager Craig Swart. In the extraction of minerals from the ground, the first action that is taken is exploration drilling, which is carried out with compressed air. If a mine is an open pit operation, then compressors are essential for initial overburden stripping and blast-hole drilling to remove the actual ore.

“Some of our smaller portable generators are roadworthy and can be towed behind a suitable vehicle, and can be rapidly deployed to site,” Swart continues. The smaller range of Rand-Air compressors range from 190 cubic feet a minute (cfm) unit to a 400-cfm compressor. These deliver seven bar pressure.

However, if there is a requirement for larger volumes, Rand-Air is able to supply a range of compressors from a 620-cfm unit to its XAS746 compressor which supplies 1500 cfm. This range will supply pressures of between 7 and 10 bar. These compressors are mounted on four-wheel trailers and need to be transported to site. “They have often proved invaluable in factory breakdown situations, as standby compressed air where an uninterrupted supply of air is crucial,” he adds.

If there is a requirement for high-pressure compressed air, Rand-Air supplies a range of compressors from the XAHS186 (370 cfm @ 12 bar) to the impressive XRVS 487 (1052 cfm @ 25 bar). These have application in mineral exploration drilling and for flaring in the petrochemical industry.

“What is new to Rand-Air is that to more effectively serve the needs of the exploration drilling industry, Rand-Air has introduced the DrillAir Y1260 variable high-pressure compressor which will deliver 1431 cfm @ 21 bar ranging up to 1226 cfm @ 35 bar. Being able to choose exactly the right pressure to match strata conditions, hole size and bit type “is proving to be a cost saver for local drilling contractors”.

Rand-Air also supplies what are known as ‘boosters’. These skid mounted units are well suited for use in the pipeline industry and an exploration drilling. They have a maximum working pressure of 69 bar and are able to deliver 2440 cfm.

Customers of Rand-Air can also source a range of various Atlas Copco electric compressors. These deliver volumes from 190 cfm – 1500 cfm at 7 bar pressure and our available on wheels or skids. They operate on 380 v with step up and down transformers. “These units are particularly useful in underground mining operations where diesel fumes would not be acceptable,” he continues.

A growth area for Rand-Air has been in the supply of oil free compressors, which supply air which is absolutely contaminant free. While there are other compressors on the market which are advertised as ‘technically oil free’, Rand-Air’s Atlas Copco oil-free compressors supply air that is 100% absolutely oil- and contaminant-free. This machine has proved very popular in the food and beverage industry, in medical applications and in particular with oil refineries and mines during major plant shutdowns. Temporary compressed air is needed to activate control systems during the shutdowns, and here Rand-Air’s oil-free air provides the answer. The PTS916 supplies 1600 cfm at 7 bar, and 1270 cfm at 10 bar. The unit can be run from 1 bar up to a maximum pressure of 10 bar. A built-in after cooler ensures the air is supplied at ambient +10°.

In addition, with its compressors, Atlas Copco supplies a range of highly efficient air dryers which are dedicated oil-free air units and are suitable for use with oil-injected compressors.

“What our mining customers like about our compressors is that they get much more than just a machine. We strive to serve our customers with bespoke solutions that exactly suit their needs and exceed their expectations,” Swart concludes.
