SOLÖ Mechanical to realise significant energy savings with an ELGi EG Series Screw Air Compressor

SOLÖ Mechanical chose the EG37 VFD compressor to improve efficiencies at their Eskilstuna plant in Sweden

Waterloo, Belgium, 28 July 2021: ELGi Compressors Europe, a subsidiary of ELGi Equipments Limited, one of the world’s leading air compressor manufacturers, announced today that one of its customers, SOLÖ Mechanical, will realize up to 20,000 EUR in energy savings over the next five years with an ELGi EG Series screw air compressor.

SOLÖ Mechanical, a Swedish provider of sheet metal and cutting, processing, welding and assembly services, was looking for a partner to resolve the efficiency, noise and pressure issues they faced with their erstwhile air compressor. The ELGi team in Sweden conducted an energy audit of the compressed air system using the ELGi Air Audit which identified inefficiencies and provided recommendations for an upgrade along with expected savings and cost estimates.

Based on the audit’s recommendations, SOLÖ Mechanical decided to replace their aging compressor with an ELGi EG37 VFD (Variable Frequency Drive) unit. The ELGi Air Audit analysis (also confirmed by an independent third-party consultancy) estimates that SOLÖ Mechanical will save approximately 350 EUR a month or up to 20,000 EUR in five years in energy spends, from upgrading to the EG Series. After having commissioned the unit in January 2021, a recent energy audit conducted confirms the energy savings. After only 5 months, ELGi’s EG Series has already saved SOLÖ Mechanical 1,630 EUR.

“We’ve been looking for a partner that could provide us with an accurate overview of our compressed air needs while recommending a solution that could deliver reliable, uninterrupted, compressed air at lower operational costs,” said Tommy Bolinder, Maintenance Manager at SOLÖ Mechanical. “The team at ELGi suggested an air audit, which clearly indicated the improvement areas along with recommendations for what steps we needed to take and what savings the project will generate. They showed us how we can save 4,364 kWh of energy a month just by replacing the present compressor. Numbers speak for themselves, so it was easy to make this decision as it is a 47% saving on my energy bill.”

“Understanding the performance and efficiency of compressed air systems is critical in every industrial application as it directly influences our customers’ bottom lines,” said Patrik Almström, Area Sales Manager Sweden at ELGi. “With the ELGi Air Audit we present a clear picture of how they can reduce power consumption, the load and wear and tear of their compressed air systems, while extending life-time and lowering life-cycle costs. With the air audit results from SOLÖ Mechanical, we provided a tailored solution for the compressed air requirement; one that maximises the customer’s energy savings.”

The robust design of the EG Series compressor range enables operations at extreme temperatures – from cold to hot and from dry to extremely humid conditions, leading overall to a higher reliability of the compressed air system. ELGi’s high efficiency airends are equipped with in-house developed η-V profile rotors, with 4/5 lobe combination, designed to run at low rotor speeds. This unique design reduces pressure losses and together with the OSBIC (Oil Separation by Impact and Centrifugal action), 3-stage separation provides best-in-class energy efficiency.

Thanks to low operating speeds further improved by the operational Variable Frequency Drive (VFD), the compressor can adapt to the changes in demand, and optimize the air flow saving energy costs. These EG compressors run very quietly, which also contributes to improved employees’ comfort at the SOLÖ Mechanical plant.

The EG Series is backed up by ELGi’s industry-leading warranty program with no limitation of running hours and comes with 10 years warranty on the airend, 5 years warranty on the compressor package, 3 years on the VFD and 1 year on electrical, rubber and plastic parts.
