Key Features

SPG is available with a wide range of options to meet the needs of even the most demanding customers

Low life cycle costs

The expense of a blower ownership is comprised of equipment, installation, energy, and maintenance costs. Equipment and installation are a one-time expense, while energy and maintenance are continuous costs of ownership. SPG ensures a high level of efficiency (> 75%) within a wide compressor rotation speed range reducing energy consumption. In addition thanks to its robust construction and use of minimum parts contribute to high reliability and long intervals between maintenance.

Flexible

The SPG screw compressor offers a turndown capability in flow to meet the needs of the customer. It’s also suitable for intermittent use with frequent stops and restarts to best satisfy the specific process requirements. The belt drive ensures the right capacity for the application, and also allows the installation of the motor most suitable for the power absorbed by the compressor (therefore operating at optimum efficiency).

Quiet operation

The optimum efficiency of the internal compression, guaranteed by the innovative Pedro Gil rotor profile, means less noise during the compression phase. The low rotor rotation speed (max. 6,000 rpm) and the absence of a step-up gear, along with special silencers and a noise-reducing enclosure (also available without sound hood – SPGL version), guarantee low noise levels from the compressor, thus allowing installation in a variety of applications.

Easy installation and maintenance

As it can be transported with a forklift and/or pallet truck, the SPG offers easy installation. The electrical system connection is also simple, using the rear auxiliaries’ cabinet for configuration with controller.

Furthermore, maintenance costs are reduced as every component of the Screw has a simple and robust construction, thereby guaranteeing a long working life. Thanks to the simple layout of the unit components, all routine maintenance tasks can be carried out from the front of the compressor, ensuring:

Reliable

The painstaking design and meticulous choice of each component of the compressor, together with a low operating speed, make the SPG extremely reliable. At the same time, the controllers ensure optimum machine operation via the continuous monitoring of the operating parameters. The functions of remote diagnostics and predictive maintenance are proven to contribute to reducing downtown.

Tailor made

The design of the SPG can be tailored in order to meet customer needs and match the application requirements.
