Description
The Waring Commercial CB15 is a true commercial blender, not a domestic machine with commercial styling. Waring lists a 3.75 HP motor, a one gallon stainless steel container with two handles and lid clamps, three speeds with a MAX PULSE function, an electronic membrane keypad, NSF and cETLus certification and a three year limited warranty. It weighs 32.1 pounds, measures 15 by 15 by 22.25 inches and runs on 120 volts through a standard NEMA 5-15 plug. It has been in production since at least 2004.
The One Gallon Stainless Container
This is the specification that separates it from everything else in this catalog. A gallon is 128 ounces, close to double the 72 ounce pitchers on the largest domestic blenders, and it is stainless steel rather than plastic or glass.
Stainless is the commercial choice for good reasons. It does not craze, cloud or scratch the way polycarbonate does after months of daily use and hot washing, it survives being dropped, and it can go through a commercial dishwasher repeatedly. It has one clear disadvantage: nothing can be seen inside it. On a domestic blender, watching the vortex is how a cook knows when to stop. On this machine the operator works blind and relies on time.
The two carrying handles and the lid clamps are the other commercial details. A full gallon of liquid is heavy and awkward, and a lid that clamps rather than press fits will not lift under pressure from a hot or gassy blend.
Understanding the 3.75 HP Rating
Horsepower figures on blenders need reading carefully, and this one is worth working through honestly.
Waring rates the motor at 3.75 HP. One horsepower is roughly 746 watts, so 3.75 HP would be about 2,800 watts of mechanical output. The machine runs on 120 volts through a standard NEMA 5-15 plug, which is the ordinary North American 15 amp household plug, and a 15 amp circuit at 120 volts can supply a maximum of 1,800 watts.
Those two figures cannot both describe sustained output. Blender horsepower ratings are conventionally peak or motor rated figures measured at stall or startup, not the continuous mechanical power delivered during a blend. This is an industry convention rather than a Waring quirk, and the same applies to every blender advertised in horsepower. The Breville Super Q takes the opposite approach by quoting 1800 watts, which is the electrical ceiling on a 15 amp domestic circuit and a more directly meaningful figure.
None of this means the machine is underpowered. It means the 3.75 HP number cannot be compared against a wattage figure from another manufacturer without translation, and buyers should not assume it delivers more sustained power than any other 15 amp appliance can.
Certification, Controls and Duty Rating
NSF certification matters in commercial food service, where health inspection requires equipment certified for food contact and cleanability. cETLus is the electrical safety certification for the United States and Canada. Neither is relevant to a home cook and both are mandatory for a commercial buyer.
Waring rates the machine for more than 100 drinks per day, which is a duty cycle statement rather than a capability one. It is telling a buyer how hard the machine can be worked, not how well it blends.
Three speeds and a MAX PULSE button on an electronic membrane keypad is a deliberately short control set. A membrane keypad is a sealed flat surface with no gaps for liquid to enter, which is why commercial equipment uses them, and it wipes clean in one pass.
Highlights
- One gallon stainless steel container with two handles and lid clamps.
- 3.75 HP commercial motor, rated for more than 100 drinks per day.
- Three speeds plus a MAX PULSE function.
- Sealed electronic membrane keypad.
- NSF and cETLus certified.
- Stainless steel blade, removable for cleaning.
- 120 volts on a standard NEMA 5-15 plug.
- Three year limited warranty. Made in the USA with US and foreign parts.
- 15 by 15 by 22.25 inches, 32.1 pounds.
Things To Consider
At 32.1 pounds and 22.25 inches high this is the largest and heaviest blender in this catalog by a wide margin. It will not fit under a wall cabinet, it will not be moved casually for cleaning, and a 15 by 15 inch footprint is a significant piece of counter.
The stainless container cannot be seen into, so blend progress is judged by time and sound rather than by eye. Anyone used to watching a glass or plastic jug will find that an adjustment.
No amperage figure is published, though the NEMA 5-15 plug confirms a standard 15 amp circuit. A machine of this power will use a large share of that circuit, so sharing it with a kettle or toaster is a realistic cause of a tripped breaker.
Three speeds is minimal for domestic cooking. There is no variable speed control, no timer, no preset programs and no soup or hot blending function, all of which domestic machines at a fraction of the price provide.
The rating average is 4.1 out of 5 from 72 ratings, the second lowest among the blenders here, on a small sample of what is mostly a trade purchase.
A gallon container is also a poor vessel for a small quantity. Blending a single smoothie in a one gallon jar produces a thin film around the blade and very little else. Anyone blending one drink at a time should be looking at the personal size blender range instead.
Who It Suits and Who Should Look Elsewhere
This suits a commercial kitchen, a bar, a juice operation or a catering setup: somewhere that blends large volumes repeatedly, needs NSF certification for inspection, and values a container that survives a decade of daily washing. The gallon capacity, the clamped lid and the sealed keypad are all built for that environment and they work well in it.
It is the wrong machine for a home kitchen in almost every respect: too large, too heavy, too loud, too little control and far too much capacity for domestic quantities. Households wanting commercial durability at a domestic scale should compare the Blendtec Connoisseur 825 or the Breville Super Q, and everyday alternatives sit in the countertop blender category.
