Hurricane Portable Booster

Model: B7-41/1000 Portable Booster

Model B7/1000 Portable BoosterStandard Scope of Supply

The Atlas Copco Hurricane booster B7-41/1000 is a single-stage oil-lubricated piston-type air/nitrogen compressor, powered by a liquid-cooled, six-cylinder turbo-charged, inter-cooled Caterpillar COM III/Tier 3-compliant diesel engine.

The unit consists of one high-efficient liquid-cooled booster block (pumper), air pre-cooler, scrubber tank, air aftercooler, safety valves, diesel engine, engine cooling, and control systems - all mounted on a strong steel base skid.

A small day tank of 20 gallons and external fuel tank connections complete the standard scope.

Special attention has been given to the overall product quality, user friendliness, ease of serviceability, and economical operation to ensure best in class cost of ownership.

Principle Data

Hurricane Booster

  • Atlas Copco Hurricane boosters are second-to-none. They are smaller, lighter, and still pack as much power as the larger and heavier comparable units of our competitors. Over 40 years of experience has taught us to maximize every component. The Hurricane booster provides you with a faster pressure build-up, a better penetration rate, cooler bit temperatures, and longer bit life.
  • The 4-cylinder booster block model 275 includes vertical reciprocating pistons, concentric air valves, and a liquid cooling system.

Compressed Air System

  • The incoming pre-compressed air from the feed-air compressor(s) goes first into a standard pre-cooler with a performance of A+15°F. The suction scrubber tank separates the condensate, which can be drained through a manual drain valve. A high level shutdown switch ensures proper operation. For multi-stage booster an intercooler+scrubber tank is installed before each stage to take out the moisture. The standard air after-cooler has a performance approach of A+50°F. The booster coolers are high pressure tubular/fin design.
  • The back pressure valve at discharge guarantees a minimum discharge pressure of 600 psi (adjustable). This device eliminates low load conditions and related condensate issues.
  • Between each compression stage a safety valve is installed to safeguard your equipment and operations.

Booster Cooling System

  • The booster block and the concentric suction/discharge valves are liquid-cooled. The coolant system is connected to the standard engine coolant system. This guarantees an optimal operation in high ambient temperatures up to 125°F.
  • A unique advantage of liquid-cooled concentric valves is that the temperature gradient is kept to a minimum. This ensures a longer valve life.

Booster Regulating System

  • The booster capacity depends on the engine speed and the suction air pressure (see capacity chart).
  • The engine speed can be adjusted manually to match the capacity of the feed-air compressor(s).
  • The pressure switch at discharge is factory set to 1080 psi. Above this pressure the load/unload valve will open and the high pressure air will flow back to suction side. At the same time the diesel engine will slow down to 1200 rpm idle speed, which results in big fuel savings.

Engine: Caterpillar C7 ACERT

  • COM III/Tier 3 compliant six-cylinder, liquid-cooled diesel engine provides ample power to operate the booster continuously at full-load.
  • The engine has the capability to start the compressor to -14°F without the addition of a cold start aid. Cold weather kits are available for up to -20°F.

Fuel System

  • The booster is standard equipped with a small day fuel tank (20 gal.) for short test runs, and with external fuel tank connections for connection to a bulk fuel tank. Optionally a big fuel tank can be installed for 8 hours running at full load (85 gal).
  • Low fuel level switch is included.
  • Fuel system includes a 10 micron pre-filter and 3 micron high efficiency filter along with standard Caterpillar water separator.

Engine Cooling System

  • The cooling system consists of an integrated aluminum oil cooler, intercooler, and radiator with axial fan to ensure optimum cooling. The cooling system is suitably designed for continuous operation in ambient conditions up to +125°F.

Electrical systemElectrical System

  • The booster is equipped with a 24 volt negative ground electrical staring and operating system.
  • The control panel includes a ComAp engine controller as standard with pressure gauges, load/unload switch, engine speed control, and monitoring.
  • The digital ComAp controller monitors all critical booster and engine functions and parameters. It is programmable, and a historic event log enables easy fault finding. The read-out is done on the LCD screen.

Safety Devices

The booster will give a warning and/or shut down in the following conditions:
  • High suction air temperature
  • High discharge air temperature (1 sensor per cylinder)
  • High discharge air temperature differential
  • Low suction air pressure
  • High compression ratio
  • High liquid level in scrubber tank
  • Low engine oil pressure
  • High engine coolant temperature
  • High engine speed
Safety devices installed
  • Emergency stop
  • Safety valves at suction and discharge
  • Battery disconnects

Maintenance and Repair

Genuine Parts
  • The booster is delivered as standard with genuine consumables, with radiator coolant PARCOOL, and with mineral PAROIL 15W40 for both engine and booster block. For extreme conditions the synthetic PAROIL 5W40 is the recommended oil.
  • Detailed maintenance schedules are available for each booster model. Standard service packs for the 250-hour intervals include all consumables and make preventative maintenance as easy as it can get.
  • Valve repair and piston repair kits can be ordered for corrective maintenance.
  • Recommended spare parts proposals help customers to identify which main components they should place in stock to maximize the uptime of their equipment.
