B4-41 1000psi 1350cfm 113kW Booster Compressor

The Atlas Copco B4-41 1000psi 1350cfm 113kW booster compressor is a single-stage, oil-lubricated, high pressure booster compressor, powered by a Cummins QSB 4.5L industrial diesel engine. Powered by the Cummins QSB4.5L industrial diesel engine delivering 113 kW (152 bhp), this unit outputs a maximum flow capacity of 1350 cfm (38 m³/min) at full suction pressure of 350 psi (24 bar).

Product Overview

The Atlas Copco B4-41 1000psi 1350cfm 113kW booster compressor is a robust single‑stage, oil‑lubricated piston‑type portable booster compressor built to elevate inlet air or nitrogen from primary feed compressors up to 1000 psi (69 bar) discharge pressure. Powered by the Cummins QSB4.5L industrial diesel engine delivering 113 kW (152 bhp), this unit outputs a maximum flow capacity of 1350 cfm (38 m³/min) at full suction pressure of 350 psi (24 bar).

This booster does not work as a standalone compressor. It pairs perfectly with Atlas Copco primary feed‑air compressors for field‑critical high‑pressure gas delivery. Engineers design this compact, lightweight skid‑mounted machine for harsh remote‑site environments. It serves mineral exploration, blast‑hole drilling, water‑well and geothermal drilling, oil & gas exploration, nitrogen generation, pipeline services and well‑service operations. It delivers faster penetration rates for drilling jobs while keeping overall transport and operating costs low. Manufactured under ISO 9001 quality and ISO 14001 environmental management standards, every unit uses genuine factory components for long‑term stability and consistent performance. You can select either open skid or protection‑frame configuration based on your site‑protection requirements.

Core Working Principle

The B4‑41 booster uses positive‑displacement single‑stage piston compression to raise incoming gas pressure. Lower‑pressure compressed air or nitrogen flows from your feed compressor into the dual‑inlet suction manifold. The piston block compresses gas inside water‑cooled booster cylinders. Two‑way concentric valves control gas intake and discharge during each piston cycle. The unit maintains a maximum compression ratio of 2.87:1 to avoid harmful condensate formation inside compression chambers.

Built‑in pre‑cooler and after‑cooler assemblies reduce gas temperature step‑by‑step before discharge. The pre‑cooler delivers +15 °F (8 °C) temperature rise, and the after‑cooler limits output air temperature rise to +50 °F (28 °C). An integrated booster bypass valve lets operators connect the primary feed compressor to downstream pipelines before booster activation, enabling safe, gradual pressure build‑up for your workflow. The Xc4004 digital controller coordinates engine speed adjustment, automatic load‑unload cycles, and full‑system condition monitoring throughout operation.

Key Applications

This high‑pressure booster fits multiple demanding field‑operation scenarios:

1. Drilling operations: Blast‑hole drilling, mineral exploration drilling, water‑well drilling and geothermal drilling. Higher discharge pressure improves bit penetration speed and extends drill‑bit service life.
2. Oil and gas field services: Pipeline pressure testing, pipeline purging, well‑site servicing.
3. Nitrogen‑generation workflows: It boosts nitrogen output from upstream nitrogen generators for high‑pressure inert‑gas assignments.
4. Rental‑fleet deployment: Compact footprint and easy maintenance make it ideal for equipment rental companies serving remote project sites.

Outstanding Product Features & Benefits

Smart Xc4004 Digital Control System

The Xc4004 full‑function digital instrument panel serves as the operation nerve centre of the B4‑41 booster. Its 7‑inch touch screen displays all core working parameters including pressure values, temperatures, running hours, fuel consumption and engine speed. It hosts built‑in fault indicators and automatic protection‑shutdown triggers. It monitors discharge temperature for every cylinder valve independently, stores historical operating data, supports audible alarm alerts and offers optional remote‑control access. Operators adjust target pressure and engine speed directly on the interface. The controller cuts off machine operation automatically when it detects dangerous conditions such as high discharge air temperature, low engine oil pressure or high coolant temperature, and it prevents catastrophic core‑component damage.

Robust Mechanical Design

– Water‑cooled booster block: The water‑cooled piston assembly stabilizes operating temperatures, extends concentric valve service life and delivers stable performance under high‑humidity and high‑ambient‑temperature field conditions.
– Integrated pre‑cooler, after‑cooler and suction scrubber tank: These components remove moisture from incoming gas flow and reduce thermal load on internal parts. A pre‑cooler bypass system expands adaptability across variable working scenarios.
– Safe pressure‑relief hardware: Suction‑side and discharge‑side safety relief valves, low‑pressure suction‑inlet switch and emergency‑stop button deliver multi‑layer equipment safety protection.
– Field‑friendly skid layout: Single‑point lifting lugs and forklift slots simplify loading, transport and on‑site positioning for remote locations. An on‑board fuel tank reduces auxiliary‑equipment requirements.
– Automatic load‑unload system: This system matches booster output to feed‑air compressor performance, cuts unnecessary fuel burn and optimizes energy consumption during partial‑load cycles.

Service‑Friendly Construction

Atlas Copco engineers this booster for fast, straightforward field maintenance. All key service points sit within easy reach. One qualified service technician completes routine maintenance work within four hours without special lifting equipment or custom tools. Factory‑approved service packs cover 250‑hour and 500‑hour service intervals. You can order dedicated valve‑repair kits and piston‑repair kits for corrective maintenance. The unit ships with PARCOOL EG coolant and PAROIL E mineral oil as standard consumables; you select PAROIL Extra synthetic oil for extreme‑climate assignments.

Recommended Operation & Maintenance Guidance

You always verify that your primary feed‑air compressor delivers gas within the 24 bar maximum suction‑pressure rating before you start the booster. Confirm all safety relief valves and temperature sensors function correctly for every work shift. Operators observe the green‑zone performance range marked on capacity charts to maximize concentric‑valve service life; yellow‑zone operation will accelerate valve efficiency loss and wear rates.

Carry out preventive maintenance strictly following the official service‑schedule documentation. Use genuine Atlas Copco parts to retain valid factory warranty coverage. The official warranty provides 12‑month coverage from start‑up date or 18‑months from shipment date (whichever comes first), limited to maximum 2000 running hours and conditional on genuine‑part usage.
