Why Condensate Drains are Critical to Compressed Air System Efficiency

Condensate drains are a commonly overlooked and forgotten component in a compressed air system, nevertheless they play a critical role in ensuring an efficient and reliable system. No matter how much investment is made in efficiency boosting features like Variable Speed Drive (VSD), correctly sized air receivers or lowering system pressure for example, neglecting to install and manage condensate drains correctly will offset some or all of your efficiency gains and cause ongoing headaches due to poor system reliability and increased operating costs.

rWhat to consider when buying a new air compressor

What do I Need to Consider When Buying a New Air compressor?

When buying a new air compressor, to select the right air compressor is vital to ensure you keep your energy and maintenance costs to a minimum and to deliver long term operating cost savings. Selecting the wrong compressor for your application can lead to thousands of dollars wasted in inefficiencies.

There are a number of things to consider to ensure you get the right air compressor for you, 10 important considerations include:

1) What are you using compressed air for?

How you are going to use the compressed air will dictate the best type of air compressor for your application. Gaining a thorough understanding of your usage by determining how much air you need and when you use it will guide you to the type of air compressor best suited to deliver it efficiently. For existing systems a thorough air audit will help you identify an exact usage profile which can then be used to make informed decisions on requirements.

reciprocating compressor vs screw compressor

Reciprocating vs. Screw Compressor, Which Should I Buy?

For customers looking for a new air compressor in the 5-15 kW power range this is a common question.

The answer is it depends on the amount and frequency you require compressed air that dictates the type of compressor suited to your application.

If you are a frequent user of compressed air, as in you require compressed air for long durations of time, such as an entire shift, generally a rotary screw compressor would be best suited to your application. Rotary screw compressors perform at peak efficiency when run for long periods of time and are not suited to short periods of demand and long periods off duty. The majority of rotary screw compressors are oil lubricated so not unlike an engine the warmer it gets the better the lubrication and higher the efficiency. Running a rotary screw compressor in short bursts can cause excessive wear and tear due to running cold, decreasing efficiency and increasing maintenance costs. Rotary screw compressors are generally more expensive than reciprocating compressors but they also come with advantages such as superior efficiency (in suitable applications), and can be programmed to turn off during breaks or at the end of the shift to avoid energy usage when no compressed air is required.

Melbourne Heatwave Takes its Toll

In early January Melbourne sweated through the worst heatwave in 100 years. Four consecutive days over 40°C and overnight temperatures above 25°C not only took their toll on people but also tested the limits of every compressed air system.
Southern Cross Compressors received a number of calls for help from customers with compressors shutting down due to overheating. The extreme heat caught out many plants that had compressed air equipment not capable of handling these extended periods of extreme heat.
The weather highlighted the importance of ensuring companies select compressors and ancillary equipment designed to handle the Australian climate.

Two-Stage Compression Can Save you Thousands of Dollars in Energy & Maintenance Costs

If you require a rotary screw compressor 90kW or above than you should consider the benefits of a two-stage compressor over a typical single stage machine. Single-stage compressors use one airend to compress air to the required system pressure whereas a two-stage compressor separates the compression process over two separate airends.
A two-stage screw compressor can provide total efficiency savings of between 15-20% over a single-stage equivalent screw compressor, resulting in a fast payback on the additional capital investment. In any plant that equates to significant energy and maintenance cost savings per annum.

New Air Compressor Rebuild Centre Completed

A key feature of the new Southern Cross Keysborough operation is a state of the art airend rebuild centre. This specialised workshop is where customers rotary screw air ends will be returned to original manufacturers specifications.

Rebuilding a rotary screw airend requires specialist skills, tools and equipment. Southern Cross has invested in a first class facility to gives us the best chance of getting the optimum service life out of an airend. Rotary screw air ends, like any rotating equipment, require overhaul from time to time. These precision engineered components are the heart of any screw compressor. Correct bearing replacement must be undertaken in a controlled environment to prevent dust and other contaminants from impacting the life of new bearings.
