SOLÖ Mechanical to save energy with ELGi EG Series Screw Air Compressor

SOLÖ Mechanical chose the EG37 VFD compressor to improve efficiencies at their Eskilstuna plant in Sweden.
India, July 28, 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. The audit identified inefficiencies and provided recommendations for an upgrade along with expected savings and cost estimates.
Based on the audit's recommendations, SOLÖ Mechanical replaced 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) estimated that SOLÖ Mechanical would 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 confirmed the energy savings. After only five 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 the steps we needed to take and what savings the project will generate. They showed us how to save 4,364 kWh of energy a month 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."
Thanks to low operating speeds further improved by the operational Variable Frequency Drive (VFD), the compressor can adapt to the changes in demand and optimise the airflow, saving energy costs. These EG compressors run very quietly, contributing to improved employees' comfort at the SOLÖ Mechanical plant.
