The Hydrodemolition and Industrial cleaning process starts with the High Pressured water. Aquajet Systems AB is a supplier of the whole package of products that cover the Hydrodemolition and Industrial cleaning business needs.
Besides the Aqua Cutter robots the Power Pack is the core products in the program. Aquajet Systems presents a complete range of Power Packs, and with its broad performance we cover all needs of different pressures and flow.
The Skid mounted Power pack can be equipped with the Diesel engine and High Pressure pump to reach the same efficiency as the containerised Power Pack. The skid mounted unit is a budget version for those customers that want to do the end fitting them selves, in a container or on a trailer concept.
Option: Wireless Radio Remote Control. The skid unit can be installed into a 20ft uninsulated steel container, painted and air ventilated.
-Only one container for all.
-Self supplied, no external electricity.
-Easy handling and cost efficient in transport and set-up time.
-Minimum space required at the site.
-Robot and accessories are in the container for convenient transport and storage.
The diesel engine and the high pressure pump are connected by means of a flexible coupling and assembled complete on a heavy-duty welded steel
frame.
The base frame is installed in the container on vibration isolators.
A bag-type water filter prevents impurities from entering the system and pump.
A booster pump is mounted between the water tank and the high-pressure pump to provide adequate inlet
pressure.
The safety shutdown system will automatically shut down the unit, or return it to low
idle, in case of any malfunctions or safety alarms.
Remote Control system with pressure on/off switch and emergency stop.
When the remote control is switched to off position, the system will depressurize the pump and high-pressure hose and reduce the engine rpm to low
idle.
The container is sound insulated with a double door on the right side, double rear doors and hatches for the cooling air.
The container can be equipped with a ”Roll off” frame, for easy on/off truck loading and transport.
Built in workbench with vice and storage room for spare parts.
Movable heavy hooks for storing of HP-hoses and cables.
24 volt electric system for lighting.
Built in fuel tank and water tank.

Our containerized Power Packs have space also for the robot and accessories such as hose lines etc.
Only one container is necessary and it is completely independent from power supply or any other external utility except from water and diesel
fuel.
One container means one truck-, which means easy transport, short mobilisation and demobilisation for your
advantage.
Contractor AND operator friendly system.
In short: self-contained system ready to go to work.
ECO SILENCE
AQUA CUTTER ECOSILENCE - POWER PACK PP-700
Environmental issues are of increasing importance to Hydrodemolition contractors. Stringent regulations are increasing the pressure for town centre operations to be kept quiet to avoid disruption to nearby residents and
businesses. Escalating fuel prices and concerns about emissions are driving the need for ever more efficient plant.
Aquajet Systems AB has tackled both aspects with the launch of a revolutionary new power pack that represents a significant advance for the sector and can be used for anything from scarifying to deep concrete removal. The ECOSILENCE Power Pack’s noise levels are similar to those of a normal conversation and it can easily save 30l/hr in
fuel.
Noise is one of the greatest challenges in the Hydrodemolition sector and contractors are keen to find quieter power packs to avoid complaints from clients and the public. The new power pack is the result of a project that Aquajet started three years ago to meet the challenge of engineering and designing a completely new system with noise levels at least 10dB less than conventional
models.
A reduction of 10dB is recognized by the human ear as being half as loud – and the values from ECOSILENCE are even better than the original
target.
At 66.5dB, the noise from the new power pack represents a dramatic improvement in the sound levels that people will
experience. In contrast, conventional power packs create higher noise levels of between 78dB and 82dB, depending on the manufacturer and the type of
application. These levels – which can be compared to the noise from traffic or a motorcycle - can be a considerable problem when carrying out urban projects close to residential and office areas.
Use of the ECOSILENCE Power Pack also achieves a substantial reduction in fuel consumption over conventional designs, saving an estimated €35,000 a year in typical operation. Traditional power packs use between 105 l/hr and 120 l/hr of fuel and consumption is of increasing concern both in environmental terms and because of today’s escalating
prices. ECOSILENCE has achieved a dramatic reduction, to just 70 l/hr when producing 189 l/min at 1000 bar at 73% of full power.
Aquajet´s engineers have addressed all aspects of power pack design and
manufacture. Many engineering and design innovations have been combined, such as a 40% increase in sound
insulation, including the provision of tailor-made seals for all doors and hatches to block noise
propagation. Wall construction has also been enhanced, with an acoustic surface treatment and sound-absorbing insulation to reduce noise and vibrations.
The power packs purpose-built steel enclosure features two hydraulically-operated hatches for the engine
compartment, enabling the operator to vent any excess hot air between operations.
ECOSILENCE uses an advanced heat exchange system in place of traditional cooling and its exhaust silencer also incorporates new
criteria, with every aspect rigorously considered.
The system’s design features a new vibration dampener as well as pipes, hoses and tubing that have all been refined and improved in line with the new design approach.
The choice of a Volvo engine was an important aspect of the development. The engine had to combine power and durability while meeting all of Aquajet´s requirements in terms of
flexibility, quality and performance. A key factor was its very high torque range from 1100 rpm up to 1800 rpm, which means that the operator never needs to use more energy or power that the task
requires.
This type of engine was also found to be particularly suitable for the
application, thanks to its low noise characteristics. Fuel efficiency was another crucial aspect in today’s operating
environment.
The high pressure water output is from a 700hp plunger pump, which gives good performance even at 1280 rpm. Its output of 189 l/min of water at 1000 bar achieves a respectable production rate for concrete removal, with exceptionally low fuel consumption of just 70 l/hr.
This can mean a saving of 30 litres of diesel an hour compared to a conventional system, which can equate to a financial saving of €35,000 during an 800 working hour
year.
Water flow and pressure can be tailored to suit the application in hand. A water output of 181 l/min at 500 bar uses just 40 l/hr of
fuel. The ECOSILENCE can be used to provide up to 261 l/min at 1000 bar utilizing only 85% engine power output.
Aquajet has also included features to offer flexibility in transportation and maintenance of the 12, 800kg ECOSILENCE Power Pack. The 2.8m high by 7 m long unit can be delivered either with a roll-off frame for transportation by truck, or can be truck-mounted with ISO container
corners.
The Power Pack also includes workshop space, to accommodate a workbench, spare parts and
accessories.
