The SV 125/40 NG compressor is a premium category, two-stage, reciprocating compressor from J.A. Becker & Söhne, specifically designed for natural gas (NG) applications. This model is excellently suited for industrial and commercial environments requiring reliable, high-pressure gas supply, achieving a maximum operating pressure of 40 bar. The unit follows the J.A. Becker & Söhne philosophy: not a „mass-produced product” but a highly efficient, long-life, precisely engineered piece of equipment.
The SV 125/40 NG compressor possesses several outstanding features that ensure efficient and trouble-free operation:
No „Mass-produced Product” (NO 08/15 PRODUCTS): Every single unit is manufactured according to the highest quality standards, with unique engineering precision, guaranteeing long-term reliability.
High Efficiency Cooling: The two-stage design and optimized cooling system minimize heat generation, which increases the compressor's lifespan and maintains gas quality.
Fully Automatic Discharge: The built-in automatic pressure reduction and unloading system ensures a safe shutdown and depressurization of the system, thereby facilitating maintenance and increasing safety.
Long Maintenance Intervals: Thanks to high-quality components and an efficient lubrication system, the compressor allows for exceptionally long operating times between scheduled maintenance, reducing downtime and operating costs.
The performance and parameters of the SV 125/40 NG are detailed in the following table, which forms the basis of the precise design and robust construction:
| Parameter | Value | Unit of Measure | Note |
|---|---|---|---|
| Inlet pressure (Inlet pressure) | 0,02 / 0,3 | bar | Minimum / Maximum Inlet Pressure |
| Volume flow (Volume flow) | 125 / 150 | l/min | 7.5 – 9.0 m³/h equivalent |
| Maximum operating pressure (Max. operating pressure) | 40 | bar | The final pressure achievable by the system |
| Pressure stages / Cylinder (Pressure stages/cylinder) | 2 / 2 | – | Two-stage compression |
| Electric motor power (Electric motor) | 1,9 | kW | Drive unit power |
| Speed (Speed) | 1.000 | rpm | The rotational speed of the main shaft |
The SV 125/40 NG compressor is the ideal choice for areas where natural gas is used for high-pressure storage, process control, or specialized gas delivery. The two-stage design ensures that gas compression occurs efficiently, minimizing temperature rise between stages.
The maximum pressure of 40 bar enables the gas to be compressed for filling high-pressure tanks or for technological processes that require a stable, high-pressure source. The 1.9 kW electric motor provides sufficient power for the reliable delivery of a volume flow of 125-150 liters/minute.
The two-stage (2/2) design is crucial for high-pressure applications:
Temperature control: After compression in the first stage, the gas is cooled (intercooler) before entering the second stage. This process drastically reduces the energy required to achieve the final pressure and prevents overheating, which could damage seals and valves.
Increased Lifespan: Thanks to the reduced thermal load, the mechanical components are less stressed, contributing to the long maintenance intervals mentioned above.
Efficiency: Thermal efficiency was a key consideration during the design of J.A. Becker & Söhne compressors, so the SV 125/40 NG optimally converts available energy into pressure increase.
The compressor's inlet pressure range (from 0.02 bar to 0.3 bar) provides flexibility for various natural gas supply conditions. A minimum pressure of 0.02 bar means the unit is capable of operating even from low-pressure networks, provided it can ensure the required volume flow.
The operating speed of 1000 revolutions/minute (rpm) indicates low-speed operation in the reciprocating compressor category, which further enhances mechanical stability and reduces vibration.
