refrigeration unit

Latched on to a restaurant appliance the other day and have a question. This unit had a stainless steel hood and had a wood piece a foot wide and the length of the unit maybe 6 or 7' long. Underneath it had one sealed motor and it looks like 2 evapaoration units. One of the evaporation units is aluminum with copper coils. The other is only slightly larger but 2 or 3 times the weight. Meant to use the magnet but got busy breaking things a part. My question is what accounts for the heavier weight of this second unit. Also 2 small fan motors on the evaporation units. I'm thinjking that this might be like a salad bar or something similar. Lot's of copper and some aluminum and stainless and good weight on the other metal.

Was it a Delfield case?

I don't know. It came out of a Chinese restaurant. There appeared to be a lot of grease and I thought the girl said it might be a cooker but that doesn't sound right to me.

I'm looking at about 7 of these to scrap http://thumbs2.ebaystatic.com/m/m_o3...Q23a0g/140.jpg
But double sided, & longer.

So far its taken 4 trips (walking!) too the owners, 2 to the yard owners, 1 email, 5 trips to look at the items & 3 trips to the guy who I thought might be able to help me shift them (for a very good $$$) he said 'he would', now he's being evasive...

****! I just wanna scrap them, pay out the owner & the helper with good ca$h & clean up the eyesore & waste of space that it is...

Some people are just so ****, well 'stupid' is a complement.
