Your supervising attorney comes to you with the following facts and a plate of Wisconsin Cheddar and crackers:

Chester, an artisanal cheese maker, entered into a contract for the purchase of a commercial pasteurizer and related equipment from Louis, who was also to install the machinery. The installation and ongoing maintenance by a professional of the pasteurizing equipment is essential to the manufacture of cheese and achieving the related health standards.

Make an argument both for and against the application of the UCC to this transaction.

Are there any additional facts that would make a difference in the determination? What are they?
