Through inspiration for the air filtration systems for their refrigerators is by a system developed for NASA.
When they build the interior of a refrigerator cabinet, it measures to within 3/1000 of an inch to ensure a square of nearly flawless dimensions.
Obsessed with perfection? You could say that about Sub-Zero and Wolf, a premium manufacturer of built-in luxury appliances. Then, that is probably the reason why homeowners who begin kitchen remodeling projects will replace everything including their kitchen sink – but rarely a refrigerator, freezer or oven with the Sub-Zero and Wolf name on it.
So can you imagine when a company like this needs all their internal processes to be just as perfect?
At Exact Metrology, it was a call we were thrilled to answer.
“Exact Metrology has a very similar philosophy to Sub-Zero and Wolf in taking care of the customer first and foremost. Any time there is a piece of equipment we have that needs special attention, it is a call to Exact Metrology, who can provide that equipment to us on a very timely basis.”
Mark Swartz, Corporate Quality Director, Sub-Zero and Wolf
Sub-Zero and Wolf had been studying ways of how they could bring more automation to their production facilities while making sure every design specification they made was still exceeding the expectations of customers and suppliers.
Greater precision in their design measurements would provide the company with a better understanding of their internal process capabilities, which in turn would only help in the product development phase.
Taking Precision Beyond the Kitchen
Part of the challenge that Sub-Zero and Wolf faced was that they were not looking for precise data in just one part of their Madison, Wisconsin facility. They required it anywhere it was required, from the shop floor to several of their labs.
We knew this called for the portability and agility of our ROMER CMM device. When you need to take coordinate metrology “on the road” so to speak in that the device has to go where a traditional machine cannot, you can take the ROMER portable arm directly to the part for greater flexibility. At just 17 lb, the arm is the lightest device of its kind.

This is ideal for large workpieces that are a major challenge to move, especially as Sub-Zero and Wolf required several points of production for analysis that were not in any proximity to one another.
It “knows” accuracy even before you turn it on.
Precision is vital, but so is a measuring arm that does not demand a great deal in the way of set-up at each point of measurement. Thankfully, the ROMER Arm features absolute encoders at its primary axis, so there is no homing procedure necessary prior to conducting measurement. In other words, it has absolute precision built right in.
With the project a success, Sub-Zero and Wolf did not have to imagine increased capacity for production. They could measure it down to the absolute finest degree.
That was nine years ago. In addition, we have been preserving their solid reputation ever since.
That is right. We have been doing business with Sub-Zero and Wolf for quite some time now, watching them purchase a variety of our laser scanning inspection devices, a laser scanning head to each ROMER Arm so they can do reverse engineering and many large stationary measurement machines.
