The single-stage, oil-free screw compressors in the Delta Screw Generation 5 plus series are universal tools. They bundle all the know-how of a world market leader in compressor technology to offer you ‘the user’ maximum efficiency. These innovative machines are belt-driven to provide air and nitrogen applications at positive pressure, negative pressure, and in a range of nominal sizes. The flexible modular system allows for almost any combination of compressors and accessory components. The belt drive allows for optimal adaptation of the system to do the job at hand, as well as for any changes that may become necessary later. In addition, the belt drive allows for precise configuration – an important feature given that the greatest savings come from saving energy. This means, for example, that a 5% deviation in the volume stream means a 5% increase in energy consumption.
Delta Screw Generation 5 plus is the fifth generation in Aerzen’s most successful line of compressor packages and also comes with five main advantages:
Another unique feature: the screw compressors in the Generation 5 plus series come with a choice of special designed rotor profiles for added flexibility. VML compressors have a 3+4 profile and are ideal for applications up to pressure ratio 3 (final pressure over intake pressure). That means they are also perfect for negative pressure applications up to 70% vacuum (0.3 bar abs.). A special pre-inlet version can achieve up to 85% vacuum (0.15 bar abs.).VM compressors have a 4+6 profile. They are tailor-made for positive pressure ranges (up to pressure ratio 4.5) and for intake volume flows of around 120 m³/h to 2,030 m³/h.
The available outlet port choices enable the AERZEN compressor to be adapted for the process at hand. The various outlets in the cylinder, called πi, are a measure of internal compression. This flexibility is decisive. In every Delta Screw Generation 5 plus compressor, the choice of compressor type and πi can be optimized to best meet the desired pressure and volume flow. Over- and under-compression can be minimized, leading to maximizing the compressor’s efficiency.
Leading companies in industries ranging from petrochemicals to cement have been relying on AERZEN for decades, and for good reason: The Delta Screw series is unrivalled in the assortment and flexibility of available models and how they can be adapted to a wide range of customer requirements. The Delta Screw Generation 5 plus series has set a whole new standard. The new benchmark class of dry-running screw compressors.
