These compressors are built on the basis of high-efficiency screw blocks, manufactured using modern CNC technologies and laser control, which guarantees accuracy and durability. Fixed rotation speed allows achieving optimal efficiency in full load modes, minimizing energy consumption.

Efficiency and Savings in Daily Operation

One of the key advantages of fixed speed is the simplicity of design, which reduces the risk of breakdowns and simplifies maintenance. Compressors are equipped with IE3 class electric motors that meet international energy efficiency standards, and operate at temperatures up to 46°C. This allows using them in difficult conditions, for example, in hot workshops or regions with high temperature. The automatic belt tension system extends the belt's service life, reduces noise and vibrations, which contributes to comfortable work of operators.

Savings are achieved thanks to low energy losses: the integrated air/oil cooler with bypass quickly warms up the system, preventing condensate and wear. In-house production of dryers with patented heat exchangers provides low pressure drop and compactness. For business, this means reducing electricity costs by 10-15% compared to less efficient analogs, as well as minimizing downtimes thanks to reliable design. Fixed speed is the choice for stable processes, where priority is on reliability and low costs.

Application in Different Industries

Compressors with fixed speed are widely used in the automotive industry, where constant compressed air is needed for painting or assembly. In the food industry, they provide clean air without contaminants, thanks to cleaning options. For small and medium enterprises, ESM is an ideal solution, as it combines affordability with premium quality. Integration with GD Connect systems allows managing multiple compressors, optimizing the overall system efficiency. Overall, these models help business focus on production, not on equipment maintenance.

Compressors with Variable Speed: Flexibility for Variable Needs

The VS series with variable speed (Variable Speed) is an innovative solution for productions with fluctuating air demand. The speed regulation technology allows the compressor to adapt to real needs, reducing energy consumption up to 35% compared to fixed speed. This is achieved thanks to integration of motor, drive and screw block, which provides a wide regulation range without on/off cycles. VS models effectively cope with peak loads, minimizing wasteful energy costs.

Significant Energy and Resource Savings

Variable speed is the key to energy efficiency: the compressor automatically adjusts rotations to match the current demand, which reduces annual electricity costs. The C-PRO 2.0 or GD Pilot SE controller monitors parameters in real time, allowing easy pressure change with one press. This not only saves money, but also extends equipment service life, as it reduces component wear. In the e-line, manufactured in Germany, efficiency is even higher thanks to the integrated screw block with low rotations, which reduces energy consumption by additional 5-10%.

For business, this means return on investment in 1-2 years due to savings. VS compressors ideally integrate into systems with multiple units, where one VS regulates load, and fixed ones work at full. Low noise level (about 67 dB) and vibrations make them suitable for placement directly in production, without additional isolation. Resource savings also manifest in extended oil change interval – up to 4000 hours, which reduces maintenance costs.

Flexibility in Use and Integration

Variable speed allows VS compressors to adapt to seasonal fluctuations or changes in production, for example, in textile or pharmaceutical industries. Mounting options on receiver or with dryer make them compact airstation, reducing installation area by 55%. The Modbus and RS485 system provides integration with industrial networks, allowing remote monitoring. For enterprises with inconsistent demand, VS is a way to avoid overexpenses, providing precise air supply without surpluses.

Design and Construction: Engineering Excellence
