Subzero

What is dual refrigeration, and what's the advantage? Do all refrigerator units have dual compressors?
Sub-Zero is the only home refrigeration system with dual refrigeration, which simply means that the refrigerator and freezer have separate compressors. This has several advantages. Frozen foods need very cold, dry air. Refrigerated foods need somewhat warmer and much moister air. Each compressor maintains precisely the conditions needed on its side of the unit with the compressor running only when needed. In other refrigeration systems the single compressor has to pull double duty—wear and tear you avoid with Sub-Zero. In a Sub-Zero unit, thanks to dual refrigeration, air never passes back and forth between refrigerator and freezer. Which means you'll never again have frozen foods picking up unwanted flavors from the fridge. No more onion-scented ice cubes. Yes, all combination refrigerator/freezer models have dual compressors.
What is the life expectancy of your products? How does this compare to industry standards?
Sub-Zero products are at or above all industry standards. The life expectancy, as with any product, will depend upon other factors such as daily use and climate.
What is the purpose of a door stop?
A door stop limits the travel range of the door to 90° or 110°.
What is the required icemaker water supply line for my unit?
We require ¼ inch (O.D) copper tubing for units containing an icemaker.
Are Sub-Zero stainless steel units magnetic?
No.
Are the door handles included with my overlay unit?
No, please consult with your dealer and/or designer. Sub-Zero offers a limited selection of Stainless Steel handles through your local dealer.
Are the wine units available with 2 temperature?
All 400 series models have 2 independent temperature zones.
Can I switch the door swing on my unit?
ONLY on 200 or 300 under counter series. Please call customer service for information on swing change requirements.
Can I use a water filter on my ice & water dispenser?
Yes, an inline filter is recommended for water with high sediment.
Can Sub-Zero units be free standing (not built-in)?
Yes. However, the unit will still need to be blocked as specified in the installation manual and will require side panels, as the sides of the unit are unfinished.
Do Sub-Zero units run more often than the competitors?
No. It may appear so, but because there are two independent systems and compressors in our Sub-Zero products. Therefore, the freezer compressor could run, followed immediately by the refrigerator compressor. This may give the illusion that one or the other is running continuously.
Does Sub-Zero manufacture any commercial units?
No. We are strictly a residential built-in refrigeration company.
How can I obtain an additional logo tag for my unit(s)? How much do these cost?
Please contact our customer service department. Cost will vary depending on model.

What is the steel gauge on the range units?

What type of stainless steel finish is used for the Wolf products?
It is a #4 brush, the same that is used on our refrigerators.
What's the appearance of the Wolf finishes?
Stainless steel exterior and cobalt blue interior on the Dual Fuel Ranges and Wall Ovens with a black interior for the gas ovens.
What's the difference between the Wolf convection system on the new wall oven and other convection systems?
It boils down, if you'll pardon the expression, to consistency and flexibility. The Wolf system is a dual convection system, using multiple burners and blowers to produce extremely even temperature throughout the oven. Roasts brown evenly all over. Your pie crusts come out as nicely done on the bottom as they are on top. As for flexibility, the oven's logic control system uses the burners and blowers either together or sequentially to produce the best results for the type of dish you're cooking. You simply choose a cooking mode-convection bake, convection broil, etc.-and the system takes it from there. It's intuitive and easy to use, and the results are spectacular.
When a range has two ovens, are they both convection?
Yes but can be operated without fans if required.
