6 FAQs about [Screw air compressor circulating water requirements]

Do rotary screw compressors use a lot of water?

Compressed air systems consume a high volume of water to cool the compressed air circuit. Many air-cooled rotary screw compressors have seen design improvements and can accept higher ambient temperatures than in the past. In addition, customers will realize the most savings in terms of reduced water consumption.

What is the standard rating for air compressor cooling water?

The standard rating for the water used in cooling air compressors is how many gallons of water per 1,000 btu/hr is rejected into the cooling water flow. Air compressors generate a high rejection load due to their very basic inefficiency — i.e. it takes 7 to 8 input horsepower to supply 1 hp of work in compressed air.

What is the temperature limit for a screw compressor?

Standard screw compressor package design based on IIAR/mechanical code equipment room limits of 104°F (40°C). Screw package high temperature limit based on WEG motor. Other motor ratings are available for special applications. Screw package low temperature limit based on oil temperature limits.

How much water does an air compressor use?

A 125 horsepower water-cooled air compressor can consume 11.4 million gallons of water per year. A larger 350-horsepower water-cooled air compressor can consume 17 million gallons per year. A very ‘typical’ industrial plant running these compressors can consume these amounts of water.

How to choose a rotary screw air compressor?

When selecting a rotary screw air compressor, there are two cooling configurations to choose from: air-cooled or water-cooled. Air compressors create a lot of heat during their normal operation. The heat primarily comes from the motor, air end and cooling circuit.

How does a compressor water system work?

That is, the compressor water becomes cooled to 5 °C above the coolant temperature. If surrounding air cools the water, you'll need antifreeze (e.g. glycol). The closed cooling water system is filled with pure, softened water. With glycol, the compressor system's water flow must be recalculated.
