Compressed air to remove residual concrete from piling rigs up to 80 meters

J. Murphy and Sons Limited is a global company, focusing on engineering, construction, utilities and infrastructure.  Headquartered in London, they are active in Britain, Ireland and Canada; employing over 3500 people.  Atlas Copco is a long-term preferred supplier with a strong local network and reliable solutions.

Compressed air to clean residual concrete from piling rigs

Murphy uses compressed air to clean residual concrete from 4” and 5” pipes on piling rigs. The compressed air propels an appropriately sized foam ball down the pipes, for a length of up to 80 meters. For this process, they require approximately 7 bar and 175 cfm flow. The XAS 88 can deliver this with best-in-class efficiency as it is 12% more fuel-efficient compared to previous models.

For over 60 years, Murphy’s have been ‘getting the job done’. We need a long-term partner that can provide reliable equipment that will perform when and where we need it. We have numerous Atlas Copco compressors and handheld tools in our fleet. Even though they are a global company, they have a local network to help us out, no matter where our projects take us.

Integrated solution

Murphy’s main challenge was mobility. As their applications are invariably on rough ground, Murphy had needed a crane to move towable compressors on and off sites in the past. The frame-mounted XAS 88 is mounted on the back of a vehicle; cancelling the need to manoeuvre the compressor on site by crane. With its small footprint and lightweight (under 750 kg) this is an easy integration. Additionally, the 110% containment spillage free frame prevents any hassle with spillages on-site, while service is only required once every 2 years and can also be completed in under one hour thanks to the new spin-on filter. All service points are easily accessible by opening the HardHat canopy.

This PE canopy ensures the compressor continues to perform, no matter how tough the environment. Finally, the customized dark green coloured HardHat hood fits with the strong Murphy branding.

More than a compressor

Innovation is part of our processes. When Atlas Copco informed us the new 8 series could feature an integrated 9 kVA generator; we immediately found additional use for the compressors. Today, the integrated generator provides the power supply used to light the tool cabins that typically accompany the piling rig. In addition, we can also power handheld grinders and small welders.

HiLight H5+ light towers illuminate the way for AVAX SA and the construction of the Greece-Bulgaria gas pipeline

Construction Group AVAX SA has selected HiLight H5+ light towers from Atlas Copco for use on the prestigious gas interconnector Greece-Bulgaria (ICGB) construction project. These low-fuel consumption light towers are providing excellent luminosity, which is essential to ensuring workers have good visibility and can continue their operations efficiently both day and night. 

The ICGB natural gas pipeline spans 182 km and when completed will connect the Greek national gas systems in Komotini, Greece, with the Bulgarian national gas system in Stara Zagora, Bulgaria. The project is part of the final Ten Years Development Plan (TYNDP) devised by the European Network Transportation System Operators of Gas (ENTSOG), which aims to establish a single market in Europe for gas.

The two-directional pipeline is expected to open at the end of 2020, with an initial capacity of three billion cubic meters of gas per year. Gas generated from Azerbaijan’s Shah Deniz 2 gas and condensate field is set to be supplied to Bulgaria via the pipeline.

Delivering reliability and fuel-efficiency

To ensure construction operations can be carried out regardless of natural light levels, Avax SA needed reliable and robust lighting equipment that was fit for purpose and easy to operate. The lighting equipment also needed to be fuel-efficient so Avax SA could operate effectively.

The light towers were required to run for at least eight hours daily, but also continuously for up to four days when constructing in a tunnel for example. After careful consideration, Avax SA chose 10 HiLight H5+ towers for this vast construction project. The light towers were delivered at the beginning of February 2020 and put into immediate use.

Completing this project efficiently is a top priority for Avax SA, A key factor in selection was the light tower’s low fuel consumption. The HiLight H5+ LED light tower can offer a run time between refuelling of 260 hours and consumes less than 0.5 litres of fuel per hour.

A shining example

The HiLight H5+ design includes directional optic lenses that maximise practical light coverage while minimising dark spots. A single light tower has four LED floodlights each projecting 350W of light and the HiLight H5+ can illuminate an area of up to 5,000 m2; providing an average brightness of 20 lux. The LED lamps offer users higher durability without any deterioration in lux level and have a life expectancy of more than 50,000 hours.

We ordered the HiLight H5+ light towers because we have used them before and know that they are easy to use and provide excellent light coverage. First and foremost, their low fuel consumption and maintenance allow us to save on fuel and increase our productivity, thanks to reduced downtime. Secondly, the HiLight H5+ towers have a great and clear luminosity during night operation compared to other manufacturer’s products.

In addition, the light towers are mobile and easy to transport. The model’s compact size means 10 units can be moved on a standard 13-metre truck, and they can be easily set up wherever required on site.

There are 10 light tower models in the HiLight range which have been designed to offer the widest choice when it comes to finding the light tower that is right for an application. 

“At Atlas Copco, we provide a flexible and dynamic set of lighting options, while addressing all aspects of efficiency and safety,” continues Kostas Bakas. “By choosing the HiLight H5+ tower, Avax SA doesn’t need to compromise by settling on a one-size-fits-all solution. The construction company can also be assured of the robust build quality and compact size for which Atlas Copco is globally recognized.”

Atlas Copco expands the WEDA range with the S50 Sludge pump

Atlas Copco has developed a new addition to the WEDA submersible dewatering pump range with the WEDA S50. Fitting into the S family of WEDA sludge pumps, the new model complements the other pumps in the range in terms of specifications.


The WEDA S range is designed for thick, soft, wet mud or other similar mixtures. These pumps are ideally suited for construction dewatering, industrial or refining applications. The technical specifications of the new S50 model place it between the S30 and the S60 pumps. It offers a maximum flow of 1450 l/min while pumping sludge with a specific gravity of up to 1400 kg/m3. The S50 has a rated output of 4.8 kW and a maximum solid handling size of 50 mm, which is the same as both the S30 and S60 models.

“The WEDA S50 is an ideal pump for rental companies and general contractors where they don’t have to worry about what goes in the pump,” explains Hrishikesh Kulkarni, Product Manager, Atlas Copco Power and Flow division. “Accordingly, these vortex designed pumps are ideal for abrasive media and handling solids up to 50 mm (2”). The S50 fits neatly into the existing range of Sludge pumps, making our S family portfolio complete with a range from 0.5-1-3-5 and 7.5 KW.” The Sludge portfolio covers a wide range of applications such as cement plants, industrial process water, sedimentation tanks, treatment plants, construction sites etc.


The WEDA S50 comes with the standard WEDA+ features, including rotation control, phase failure protection, thermal switches in each motor winding, and 16 Amps phase shifter plugs. All WEDA+ pumps are fitted with a 20 m cable and the reinforced cable entries ensure high resistance to water leakage.

S50 pumps are built with hardened high-chrome impellers and volute which provides high wear resistance. The aluminium alloy construction also offers high corrosion resistance. All these features combine to ensure durability and reliability in harsh environments. Low weight materials have the extra benefit of making handling and transportation easy. The Sludge range along with the new S50 is, therefore, an attractive option for rental use in the construction and industrial sectors.

For extra protection, the casing rib design offers external cooling to the motor in case of dry running which gives the S50 exceptional dry running capabilities.

Everything about the WEDA S50 is configured for ease of operation and maintenance. WEDA seal systems have a unique modular design, thus allowing for flexibility and ease of maintenance. Service technicians can change S50 seals at the job site with minimum impact on pump availability. The pump has an external oil inspection plug making it a simple maintenance task to perform quick inspections.

The S50 base is designed for stability while the bottom side discharge allows the passage of solids up to 50 mm. It offers several options and sizes for connections and flow-direction is changeable from 90 to 180 degrees on the discharge.

An extensive network of dealers and service technicians support the WEDA S50 along with the entire WEDA range. Spare parts are readily available and easy to fit.

Atlas Copco QAS generators boost snowmaking capacity of Chile ski resort

To combat unseasonably low snow cover and to maintain optimal slope conditions, Ski Portillo in Chile now has five times more snowmaking capacity thanks to the installation of four Atlas Copco QAS generators powering 25 snow cannons.

Chile brings together world-class snow destinations that are key businesses for tourism and industry of great relevance for the country’s economy. Annually the country receives almost one and a half million visitors to its ski centres such as Portillo, the oldest ski area in South America.

In order to ensure ideal ski conditions on many of the resort’s intermediate slopes at times of lower than average snowfall, Ski Portillo has had to complement natural snowfall with sufficient man-made snow to cover nine snow tracks over an area of 10 hectares. During the 2019 season, a new snowmaking system was installed comprising 25 snow cannons positioned throughout slopes. These are powered by a bank of four skid-mounted Atlas Copco QAS 630 generators, housed in a plant room adjacent to the main complex.

Boosting snowmaking capacity

As a result, snowmaking capacity has been boosted to five times that of the previous season and it is now possible to create up to 16 inches of new snow over a 70-hour time period, with equipment functioning day and night if the ambient temperatures will allow.

Snow cannons require two climatic variables for their operation, a specific environmental temperature and a percentage of air humidity. When the system detects these conditions, the snow generation cycle starts up gradually. Whether it is to run for just a couple of hours or operate a full 24/7 session, it relies 100% on the power supply from the QAS machines as a single source of energy.

The new system is fully automated which allows maintenance teams to control and monitor the status of each machine at all times – even from a smartphone. The system is a combination of mobile and fixed machines, which allows uniform coverage of the slopes and the ability to move the machines as needed.

QAS generators

Each of the four QAS 630 plug-and-play generators delivers 630kVA/500kW of prime power at 50Hz and offers a combination of reliable engine power, compact design, 500-hour minimum maintenance intervals, simple paralleling and long service life. All QAS generators incorporate dual-stage filtration with a safety cartridge and dual-stage air cleaning. This centrifugal dust separation unit, together with the heavy-duty filtration system, helps to prolong the generators’ life. Although in the Portillo application the generators are protected by a plant room environment, they are essentially designed to survive extreme outdoor conditions. Units are fully protected by heavy-duty, weatherproof, enclosures which feature an integrated door sealing system comprising a unique foam and seal layering structure to ensures water-tightness and improved sound attenuation. The QAS machine’s anti-rust canopy has a unique “no weld” corner design to eliminate traditional rusting spots. Furthermore, the spillage-free frame that is standard across all QAS models helps to minimise environmental impact.

Power management system

A major feature of each of the QAS 630 units is a controller equipped with an energy management system to optimise fuel consumption and extend the useful life of multiple generators when they run in parallel to form a mobile or independent power plant.

The generators at the Portillo site incorporate Atlas Copco’s Power Management System (PMS). It is an innovative feature that manages the four generators running in parallel with load demand, starting and stopping units in line with increases or decreases in load. In this way, the load on each generator remains at a level which optimises fuel consumption and eliminates the need to run with low load levels, a situation which can cause engine damage and shorten the life expectancy of the equipment.
