3 lessons and 5 mistakes of IIoT projects

Sam Hoff, president of Patti Engineering. suggests to start collecting data only after one has identified the problem. See IIoT project success: First identify the problem, then begin collecting data. I think he meant to say "problem area", because if you know what the problem is - you do not need more data, you need [...]

Use slow time to implement small improvements

Slow production time is an opportunity to do that myriad of small projects that maintenance kept suggesting for years, but could never implement because 'production comes first'. Now is the time to do them. How to find micro maintenance/efficiency projects during slow time? When external resources are limited, what do we do? We turn [...]

Simple energy management procedure cuts energy costs during uncertain times

During quarantine time many plants face uncertain work load and even less certain revenue. The simplest way to save energy and cost to turn unnecessary machines off. This simple recommendation is rarely easy to implement, it's even more difficult to monitor. How to find if unneeded machines are turned off without breaking a bank? [...]

#10. Energy audit saved $125,000 CAPEX

Reduction of air exhaust from refrigerated room reduced cooling load and eliminated need for refrigeration plant upgrade

#9. Energy audit finds $20,000 in energy savings at a cost of a 30 ft pipe.

A perfectly efficient machines can still waste lots of primary or secondary utilities. A complex utility audit routinely uncovers how water, heat or 'cooling' can be reused. Hot water reuse at poultry slaughter house Two industrial poultry processing procedures were set in adjacent production space - vacuum pump and scalding. [...]

How much money is at your ‘energy waste’ account?

Situation Doing nothing is an investment decision too. Investment with a guaranteed return of nothing. Here is a common conversation at a manufacturing plant: Me: … Implementation will cost you $5K and save $15K within 12 months. Maintenance manager: So we save $10K?  Not much for our plant. Besides, I do not make investment [...]

#8. Energy audit busts ‘Nothing to save, Everything is automated’ belief

A common objection to doing an energy audit is that 'Everything is fine'. This is rarely the case. Here are two examples when audit uncovered saving opportunities that clients did not know existed because they believed everything was in perfect state already. Efficient equipment does not equate to efficient operation. Sanitation staff turned [...]

Energy waste is invisible, until you measure it

A prospect informed about a possible massive cost of compressed air leaks responded: “What leaks? I do not hear hissing noise from compressed air leaks on the floor.” Plant manufactures gravel. Production noise is deafening.  To hear compressed air leak would be a disaster, not only for energy bill, but likely for the whole [...]

#7. 4 sources of energy waste at plants with efficient machines

A common belief is that if plant is equipped with efficient machines it runs efficiently. Unfortunately, this is not always true. Efficiency of components does not equate to efficiency of the whole plant. Common reason for utility waste by efficient machines: Misuse: compressed air used instead of blowers or for cooling, oversized motors, excessive [...]

#6. 6 beliefs about energy efficiency busted by energy audits

We often hear: "Our plant runs at top energy efficiency because we use these procedures and settings and our efficient equipment is fully operational." Just how often is this true? With all due respect to maintenance and operational staff, recommendations of a proper energy audit are based on direct observation of operations and lots [...]
