Case Studies

Wendy’s International Inc. – Quick Service Restaurant – www.wendys.com

Market:  Point Of Sale (POS)/Information Technology (IT)

Problem:  Wendy’s could not shake serious downtime issues at scores of locations.  Critical POS equipment – including cash registers and other sensitive electronics – was being damaged by powerline surges.  In this environment (and in addition to lightning-induced surges), heavy-duty kitchen equipment cycling on and off was regularly degrading the equipment.  All too frequently, the resulting interruptions brought business to an unexpectedly sudden standstill.  Conventional surge protectors were not doing the job over time.

Solution:  An in-depth engineering evaluation of Zero Surge’s plug-in and panel mount products was conducted.  Then, restaurants having high POS register downtime were retrofitted with these advanced power quality filters.  Subsequently, the results were so successful that more than 1,000 company-owned locations in the United States and Canada were equipped with Zero Surge products to protect the POS systems, office computers, and digital menu boards.  Today, after more than three years of this protection, the chain reports a healthy “surge” in documented uptime and productivity with no suppression technology failures.  Franchised locations are now being retrofitted as part of a store remodel project.


Multiforce Systems Corporation– Electronic Fuel Controllers – www.fuelforce.com

Market:  Electronic Controls

Problem:  Multiforce Systems turned to Zero Surge to help protect its FuelForce automated fueling systems from the potentially devastating impacts of unexpected surges.  FuelForce controllers are located on fuel islands outdoors where they are susceptible to frequent power fluctuations on a daily basis. Additionally, the controller is typically configured to turn on and off ½ to ¾ horse powered motors located inside the fuel dispenser, essentially creating and exposing the system to its own transient power surges.

Solution:  By utilizing Zero Surge’s OEM open chassis modules, Multiforce was able to effortlessly integrate surge protection directly into the electronics of the controller, offering its customers total peace of mind when it comes to quality surge protection.   “As Director of Engineering, I’m responsible for the design and manufacture of all FuelForce systems, and after analyzing previous models, I soon realized that surge protection was not incorporated into our controllers – a problem that needed to be addressed immediately. Considering the demanding applications for which FuelForce is utilized and the electronics that needed to be protected, only the most reliable, highest performance surge protection would do.  Zero Surge was the only option for us.  Since incorporating Zero Surge’s high-performance surge suppression technology into our fuel controllers, we have had no reported failures due to power surges. Multiforce now uses approximately 350-400 units per year in its fuel controllers and any new design moving forward will definitely include Zero Surge technology for power protection,” said Barry Wennagel of Multiforce Systems.


Integrated Services Inc. (ISI)– Hardware/Software for Fast Lube & Car Wash Industry – www.ints.com

Market:  POS/IT

Problem:  Computer and other point of sale equipment were getting damaged by surges generated from the cycling on and off of motor driven equipment inside the garages.

Solution:  A plug in 8R15W placed ahead of the computer and POS equipment to filter the damaging surges and noise disturbances from the power line solved the problem.  According to Darren Ball, Hardware Services Manager at ISI, “I cannot imagine how many computers alone we have saved with this technology.  In all these years, there have been absolutely no surge-related failures of equipment protected by the Zero Surge power quality filters.”  ISI has been a VAR since 1991.  Thousands of fast lube centers and car washes across the United States depend on Zero Surge protection every day.


Moran Towing Corporation– Marine Towing & Transportation – www.morantowing.com

Market:  Maritime/IT

Problem:  Catastrophic shipboard fires caused by typical surge protectors containing metal oxide varistors (MOVs) prompted The Coast Guard to issue a safety alert on the use of surge protective devices (SPDs) aboard vessels.  A review of surge protection appropriate for shipboard applications was recommended with attention given to how the devices use the ground line when handling the surge.

Solution:  Zero Surge’s series mode filter technology does not use the ground line and has a proven track record in the maritime industry of superior surge protection without the risk of failure or fire.  Moran towing installed the Zero Surge 2R15Ws and 8R15Ws on the IT equipment in the pilot houses of their tug boat fleet.


GTECH – Gaming/IT – Technology Solutions for Lottery & Gaming Markets – www.gtechlottery.com

Market:  Lottery/IT

Problem:  High profits from a new Keno roll out made downtime from surge damage to equipment highly undesirable.  Even dispatching replacement machines in high volume locations meant lost sales for a minimum of several hours.

Solution:  A modified Zero Surge 8R15W with a 15 ft. cord was specified and installed into Keno locations over the course of six years to eliminate surge related downtime.  The result was no surge damage, no failures, no lost sales.


Feld Entertainment Inc. – Live Family Entertainment (Ringling Bros./Disney on Ice) – www.feldinc.com

Market:  Audio/Visual

Problem:  The 30 Amp uninterruptible power supplies used for the sound systems were suffering surge damage and premature end of life of the batteries.  The high cost of lost equipment and downtime necessitated a new solution.

Solution:  Zero Surge’s 1R-2U-30T-120 was put ahead of the 30 Amp UPS to remove the damaging surges and EMI/RFI noise disturbances.  This has resulted in increased UPS battery life and uptime for a company where “the show must go on.”


Hyondai Fire Engineering Consultants Co. – Fire Protection Engineering – South Korea – http://www.fire-hyondai.co.kr/

Market:  Fire Alarm Systems

Problem:  Fire alarm systems in government installations were suffering surge damage.  The critical nature of the application required a surge protection solution that would prevent system failure, downtime, and costly damage.

Solution:  Zero Surge’s FF1-20W-120 Facility Filters were specified into the application in 2005 and hundreds of units have been installed yearly since then.


The Church of Jesus Christ of Latter-day Saints – Mormon Church – www.lds.org

Market:  Audio/Visual

Problem:  Preventative measures were taken to protect expensive projection equipment.  Typical MOV-type surge suppression has high voltage protection ratings, much too high to adequately protect sensitive electronics.  The client also required a locking plug to insure the protection was not accidentally unplugged.

Solution:  Zero Surge semi-customized its 2R20 series with a special NEMA-L5 locking plug to fulfill the customer’s requirements.  Several hundred units were installed in key locations throughout the United States.
