What are some of the problems an oil needs to solve in refrigeration that it might not encounter other places?
For the longest time the main and only oil property the end user was looking for was low wax content and at the time naphthenic mineral oils did have a lower wax content but still they were not wax free as some marketers mistakenly called them.
Low wax content meant low Pour Point so that oil could flow at low temperatures below freezing and still protect bearings against wear and not impede heat transfer in the evaporators by turning waxy and therefore keeping that cold storage warehouse cold to prevent spoilage. Today, we ask a lot more of these oils for this application.
What are some of the more common mistakes people make when it comes to refrigeration lubricants?
The most common mistake in making industrial lubricant applications is focusing entirely on price. We may be forced, on occasion to compete on price, but we prefer to sell on the basis of cost benefits or what some of us call “Value Selling.”
In refrigeration this would translate to: Less oil carryover, less bearing wear, stay in grade viscosity, longer oil drain intervals, free used oil analysis which can cost upwards of $100, great system efficiency.
They say that on average a soft drink bottling company or a brewery spends 40% of its electricity bill on its ammonia compressors. So an energy savings of 1-3% can be a significant amount of money and this can just about pay for the lubricant purchase.
