Oil free Water injected screw compressor 55 -120 kW,  (KOMPBERG® ZWF)

Oil-free, water-injected screw compressors are a perfect fit to all applications that require clean compressed air. There is absolutely­ no risk of oil contamination and resulting production downtime – 100% oil-free compressed air is one of the competitive advantages of these screw compressors. 
High reliability as well as low operating and maintenance cost are essential benefits of BERG ZWF compressors. 
BERG water-injected screw compressors of the ZWF ranges, available from 55 to 120 kW, have been developed to ensure economic production of oil-free compressed air. 
A special feature of these compressors protected by utility patent is reflected by the fact that compressor oil usually applied for cooling, sealing, and lubrication has been completely banished from the process of compression. The oil has been replaced by the most natural of all raw materials: water. Being an ideal heat carrier, water takes away the heat of the compression process and thus ­ensures low temperatures in the system. The advantage of low temperatures is a nearly isothermal compression which is extraordinarily cost-efficient at high free air delivery.

What is Oil free screw compressor?

Oil free screw compressors are a type of air compressor that do not require oil for lubrication within the compression chamber. Instead of using oil to seal and lubricate the screws, these compressors use other methods such as special coatings, materials, or water injection to ensure smooth operation and prevent metal-to-metal contact.
Oil free air compressors are commonly used in applications where oil contamination is a concern, such as in food and beverage production, pharmaceutical manufacturing, electronics, and medical facilities. They are also preferred in situations where oil-free compressed air is essential for the end product or process. These compressors offer advantages such as reduced risk of oil contamination in the compressed air system, lower maintenance requirements, and improved air quality. However, they may have higher initial costs and require more frequent maintenance compared to oil-lubricated screw compressors.

How do Oil free compressor and Oil free Water injected screw compressor Work?

Oil free compressors and oil-free water-injected screw compressors both operate without the use of oil for lubrication within the compression chamber. In oil-free screw compressors, special materials and coatings are used to prevent metal-to-metal contact between the rotors, ensuring smooth operation and sealing. On the other hand, oil-free water-injected screw compressors inject a small amount of water into the compression chamber to provide lubrication and cooling. The water acts as a barrier between the rotors, preventing direct metal contact and reducing heat generated during compression. Both types of compressors are designed to produce high-quality, oil-free compressed air for applications where oil contamination is a concern, such as in sensitive industries like food and beverage production, pharmaceuticals, and electronics manufacturing.

What is Special about BERG Oil-free screw compressors?
