Your business can't afford to go down when the power goes out. Protect your data, security systems, inventory - in short, your bottom line - with a Honeywell commercial generator. All Honeywell Backup Generators include WhisperCheck, a weekly self-test mode which runs at a lower RPM, making it quieter and more efficient with fuel consumption. The use of PrecisionPower Technology allows for confident operation of sensitive electronic equipment like variable speed HVAC units. Keep your doors open and your customers buying during the next power outage.
