The design, and thus manufacturing process have been greatly simplified, meaning lower production costs. Models from 75hp up utilise a more advanced PLC system depending on the model being fixed or variable speed, single or 2 stage. Models from 75HP up use the same air end structure as the SR Premium models, however, motor efficiency is only offered at an IE1 level. Variable Speed models come with a standard Permanent Magnetic IP54 motor structure across the range.
SR Economy Series screw compressors still have the benefits of a customer focussed cabinet structure allowing for quick and easy servicing. All parts and spares are well priced and offer cost savings benefits to solutions focussed clients. Although designed as a cost effective compressed air solution, durability is not compromised, SR Eco series models can work in the same harsh environments as the SR Premium models and provide years of stable service. Model ranges include fixed and variable speed, single and two-stage variable speed and tank mounted package units up to 30hp.
