Intelli-Hood: Preventive Maintenance Is Critically Important (Not Just in Times of Crisis)

Preventive maintenance is truly important to your business’ operation. In the midst of the COVID-19 crisis, many business owners are continuously evaluating their corporate strategies to determine contingency plans. However, as we ride this roller coaster of uncertainty together, it is important to not just strategize for short-term implications of the virus. Now is the time to determine the best steps — like preventive maintenance and reducing the risk of damage to unoccupied buildings — to assist your company on the road to recovery.

And, just like any rollercoaster at an amusement park, the beginning and end have a pinnacle moment. Currently, we are adapting to the changes being implemented to minimize the impact. How we adapt will influence what the pinnacle moment will look like as we return to normalcy.

Of course, it is anticipated by many that financial strains will be incurred by companies across the United States as well as the world. In recent years, the buzzword “resiliency” has swept many energy tradeshows. One thing to add to this — although not glamorous — is the critical importance of executing preventative maintenance on equipment. A few benefits of preventative maintenance include:

  • Maximizing the efficiency of the equipment
  • Reducing downtime cost
  • Avoiding costly, last-ditch-effort service repairs
  • Improving reliability

Therefore, during an economic challenge, it is critically important to the bottom line of any company to have its systems operating correctly.

Intelli-Hood Preventive Maintenance

Melink Corp has implemented Demand Control Kitchen Ventilation (DCKV) systems across thousands of kitchens as an energy control measure to reduce operating costs. When preventive maintenance is not performed, it can lead to expensive repairs and downtime. Consider these examples…

Systems are designed to “fail safe,” meaning even a simple error can result in all associated fans operating at 100% speed.

One VFD reaches its end-of-life cycle and fails. Instead of replacing the component, Operations decides it is best to bypass the VFD, which now has fans operating 24/7.

These examples have obvious implications to the facility’s bottom line and operating costs.

And taking the idea of preventive maintenance even further, businesses should plan for staff turnover. For example, if a system was installed 15 years ago, the likelihood of the same staff on site is low. Therefore, it is important to have all individuals trained on the equipment to understand standard maintenance operations.

Taking Preventive Maintenance Steps

So how can your business prevent fix-on-fail for DCKV systems and other equipment?

Discuss with manufacturers to see if preventative maintenance services are offered. The cost of a service is low compared to the potential savings that can be lost with a system not operating correctly. The goal is to have a company maximize its bottom line to become financially stable or, should I say, resilient.

Think of preventive maintenance actions as opportunities. Take advantage of the opportunity to complete a preventative maintenance service. This is the time to make adjustments to maximize efficiency and provide training to your team. All this assures your facility’s DCKV system is operating correctly to maximize comfort within the work environment.

We shall all remain hopeful and confident that through working together, we can ride out the roller coaster ride of COVID-19.

Using An Air Balance Report for HVAC Upkeep

There is much hype these days in the facilities management industry about the importance of preventative maintenance, especially for critically important HVAC systems. In our experience,  we are often urgently called out to a facility because the site’s HVAC hasn’t been well maintained. While we’re happy to help, we also want to share insights so you don’t have preventable crises.

In a recent FER magazine article Realizing ROI on Planned Maintenance – author Michael Sherer quotes David Pogach, LEED GA, Longhorn Steakhouse Facilities Manager, as saying:

“We look at planned maintenance as a way of making sure equipment lasts its expected life cycle. … We know these programs work. They save money, so for us it’s not a debate of whether to spend the money now or later. We maintain our equipment.

“Planned maintenance makes the most sense for equipment that in-house staff doesn’t have the expertise or time to maintain. Most operators who have programs in place start with HVAC because putting people on the roof is a liability issue, and most foodservice employees don’t have the expertise to service HVAC systems.”

Following are ways you can use your air balance report to help start a new preventative maintenance program or audit the effectiveness of an existing one:

1)    In your report, you’ll have a list of deficiencies and recommendations for optimal operation (figure 1). First and foremost, you should schedule completion of these tasks as part of your quarterly or semi-annual preventative maintenance program.

 

2)   Another great use of a test and balance report is using the unit inspection checklists to see what should be monitored by your HVAC contractor (figure 2).

3)   The report will also include unit3)  A third way to make the most of your air balance report is to use the HVAC system layout drawings to locate and inventory all equipment that needs to be maintained (figure 3). Please note that not all test and balance contractors provide this. manufacturers, model numbers, serial numbers, pulley sizes, belts sizes, motor horsepower ratings, and a large amount of other useful data which would aid in the implementation or upkeep of any preventative maintenance program.

 4)   Finally, make sure your preventative maintenance programs include all of the items below. Omitting regular service on these is a leading causes of problem stores.

  • Change belts when damaged and verify proper belt tension
  • Replace filters quarterly
  • Clean outside air filters
  • Clean kitchen hood filters
  • Clean fan blower wheels
  • Clean grease traps
  • Clean evaporator and condenser coils
  • Verify thermostat settings are correct and someone onsite is trained how to adjust programming
