In our post, Daily vs. Seasonal Temperature Changes, we compared average daily highs and lows over the year for more than a half-dozen cities across the globe and found that virtually all of them experience daily temperature swings in excess of 20°F!
Looking specifically at California, we noted:
“If we look at the… data for Los Angeles, we can see that the average temperature change from morning to evening is still between 15°F – 20°F year-round!”
Looking at the graph below, we can see average overnight lows range seasonally from the upper 40’s to the mid 60’s, which puts average daytime highs in the range from the upper 60’s to the mid 80’s.
Los Angeles, CA
That’s pretty nice weather! No wonder they call it the “City of the Angels”!
All is Not Perfect in Paradise
California’s a pretty big place – over 1,000 miles from north to south. It includes mountain ranges like the Sierra Nevada, and desert wastelands like Death Valley. In short, there are a host of different climates represented – a veritable petri dish for the study of temperature control!
To the east of Los Angeles is an industrial area on the edge of the Palm Desert. Looking at the graph for Rancho Cucamonga, we can see that, contrary to popular belief, this desert climate holds some of the widest morning-to- evening temperature swings in the country – exceeding 30°F throughout much of the year!
Rancho Cucamonga, CA
Northern California is another mixed bag. Up the coast from LA is San Francisco. Looking at its data we can see the climate effect of that large thermal mass we call the Pacific Ocean. Here, daily temperature swings hover in the 10°F – 15°F range as do overall seasonal temperatures. It’s pretty consistent – and pretty idyllic as well!
San Francisco, CA
Moving inland, almost due east of San Francisco is another industrial area on the outskirts of Modesto.
Oh, what a difference 90 miles makes!
Without the ocean to “pacify” the weather, seasonal highs shift by nearly 40°F from winter to summer, while daily temperature swings range from 15°F in the winter to 30°F in the summer.
Because of this diversity, we work with many clients in California experiencing significant temperature problems with their dispensing processes. This includes folks from industries like printing, packaging, automotive, composites, and steel manufacturing, just to name a few. So, how is it that all of these different manufacturers experience the same issues across such diverse processes? It turns out that they all have one thing in common – they are all fluid dispensing processes.
Trouble Manufacturing in Paradise
One of our customers in the packaging industry was experiencing variation with their liner process. In our post, Avoiding One Customer Reject Makes it all Worthwhile, we outlined the process that they went through to solve a temperature-based process control issue that culminated in a very costly customer reject.
In the ideal environment of California – who knew?
But they’re not alone. In fact, this is common.
Same Story, Different Industry
Steelscape, one of our customers that coats steel coil, experienced similar situations in their industry. They related their experience in a series of articles in Coil World Magazine entitled, A Tale of Two Coil Coaters and A Tale of Two Coil Coaters: Five Years Later.
In the first article, they demonstrated how they were able to eliminate the differences between the processes in their facilities north of Portland, and on the edge of the desert outside LA. In the follow-up, they revisited their progress over a five-year period. Ultimately, in addition to the immediate gains, they were able to take the tools and create continuous improvement efforts that resulted in receiving the EPA’s prestigious National Partnership Environmental award for naphthalene reduction.
The Devil is in the Details
The bottom line here is that, whether you are making can ends or entire coils of steel, your fluid dispensing operation will be affected by changes in the weather. Your only option is to accept this fact, then find and adopt a long-term solution that provides you the ability to continuously improve – even in a place as “perfect” as the “City of Angels”.
