A range of variable-speed vacuum pumps that are claimed to have the potential to halve energy costs have been launched by Atlas Copco.
The GHS 3800-5400 VSD+ rotary screw pumps are particularly suited for large industrial vacuum users in the canning and food packaging industries.
Users can reduce their energy consumption by up to 50 per cent if they upgrade their existing centralised vacuum systems or switch from using multiple, decentralised point-of-use pumps to a central vacuum system based on one or two super-efficient GHS VSD+ machines.
Richard Oxley, vacuum product manager for Atlas Copco in the UK said: “To ease the transition to a central vacuum system we’re offering free vacuum energy audits to new customers and a 30-day no-obligation trial of the technology on certain models.”
“To illustrate this, I recently visited a company in the food packaging industry who we predicted could save in excess of £16,000 a year in energy costs by replacing their existing centralised system with a smaller number of GHS VSD+ pumps.
“Following this, an independent energy auditor was brought in to verify the results, while the pumps were on trial, who further upgraded the potential savings to the region of £20,000 a year.”
GHS VSD+ pumps are said to provide significantly higher performance levels and reduced maintenance, noise and heat emissions compared to conventional oil-sealed and dry vane vacuum pumps.
All the pumps are equipped with easy-to-use Elektronikon controllers that can be integrated into a process control system and also control other manufacturers’ vacuum pumps.
The GHS VSD+ range, previously with a maximum flow rate of 1,810 m3/h, has now been extended upwards to 5,004 m3/h, and is specifically designed to reduce maintenance requirements and life-cycle costs.
