• High Initial Investment Costs for Liquid Ring Compressors Limits Market Penetration in Smaller Industries  

Although liquid ring compressors present several advantages, including energy effectiveness and flexibility in handling damp or dirty gases, initial high investment costs are considerable inhibitors for smaller industries. Sufficient capital outlay could be required for the purchase of and installation of liquid ring compressors, which becomes problematic for smaller businesses with lean budgets or start-up projects. Besides the initial investment, such systems usually require installation and maintenance services due to technicality, therefore raising their entire cost.

The liquids ring compressors require a high investment at the outset and this can greatly limit its adoption mainly by small industries. The liquid ring compressor can vary between USD20,000 and USD100,000 depending on the model and application; installation and maintenance add to the total cost. These systems offer long-term efficiency and energy-saving benefits but the capital outlay is indeed a barrier for most small to medium-sized enterprises. The payback period for such investments may range from 3 to 5 years, which is a long-term commitment for small businesses with limited budgets. SMEs in food and beverage, mining, and pharmaceuticals, where budgets are tight, tend to focus on low initial costs, hence slow adoption of advanced technologies like liquid ring compressors.
