The growing industrial demand for compressed air requires compressor manufacturers to provide more reliable, economic and versatile compressors within a small footprint. Gardner Denver addresses these requirements, with the introduction of the new ESM / VS 7-22 series.
Without an efficient, durable air-end, a unique compressor design means nothing. That’s why Gardner Denver designs and manufactures this critical component to exacting standards. Tens of thousands of our air-ends are in operation world-wide, proving that the heart of the ESM / VS 7-22 Series can stand the test of time.
Gardner Denver product development is a balance of technology, efficiency and performance — all focused on meeting your demand for compressed air.
The ESM / VS 7-22 fixed and variable speed screw compressors are designed to meet the high requirements which the modern work environment and machine operators place on them. As a result, our belt driven ESM / VS 7–22 compressors are extremely energy efficient, quiet, reliable and easy to use, ensuring long operating life and delivery of optimal air quality.
The number of special options available makes the ESM / VS 7–22 compressors the right choice for producing high quality compressed air for a wide range of needs.
The basic ESM / VS 7-22 compressors can be equipped with useful options to meet even the toughest demands for building up a flexible compressor station. As a result, you will get a compact air solution which can be installed quickly and efficiently wherever the need for high quality compressed air exists.
includes compressor and refrigerant dryer, both mounted on a tank
From 15 kW, the compressors are available with highly efficient heat recovery systems, which can be factory fitted or are available as retrofit kits comprising all the necessary pipe-work and fittings.
The new control system ensures reliable operation and protects your investment by continuously monitoring the operational parameters.
The “GD PILOT” controller also has the capability to have programmable inputs and outputs, control additional equipment as well as providing the following features with clear readable text.
Today no modern energy efficient compressed air system is complete without the installation of an intelligent master control system.
The new GD Connect 4 is the ideal control solution for smaller compressed air stations, and will intelligently control up to 4 fixed speed compressors.
Sequencer with up to 35% energy savings!
Compressor systems are typically comprised of multiple compressors delivering air to a common header.
The combined capacity of these machines is generally greater than the maximum site demand. To ensure the system is operated to the highest levels of efficiency, the “GD Connect 12” management system is essential.
Each 1 bar decrease potentially results in a 6% reduction in energy consumption and as much as 25% decrease in air leakage losses.
