World Dryer

World Dryer is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand World Dryer rather than just read about it. In short: World Dryer Corporation is an American manufacturer of hand dryers and related products. Established in 1950 as a subsidiary of Beatrice Foods, it has also been a subsidiary of the Carrier Corporation.

Key takeaways

  • World Dryer belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect World Dryer to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of World Dryer from memory before moving on to harder problems.

Reference excerpt

World Dryer Corporation is an American manufacturer of hand dryers and related products. Established in 1950 as a subsidiary of Beatrice Foods, it has also been a subsidiary of the Carrier Corporation. In 2017, World Dryer joined the Zurn Industries brand of Rexnord Corp. It is based in Berkeley, Illinois.

History World Dryer was founded in 1950 by inventor George Clemens, with the intention of inventing and selling a new hand dryer that could compete against paper towels. Three years later, Clemens patented a new hand dryer design, called the Model A. The original version of the Model A featured a wall-mounted assembly, a cast-iron cover, push-button operation, and a swivel nozzle. Beginning in 1955, World Dryer began manufacturing and exporting units internationally via a partnership with UK-based Warner Howard Limited (later taken over by Caerphilly-based Personnel Hygiene Services). In 1968, World Dryer introduced a version of the Model A with a recessed assembly rather than a wall-mounted version. This version, called the Model RA, was modified slightly in 1990 to ensure compliance with the Americans With Disabilities Act of 1990, and was further modified in 2005 with a squashed nozzle (Q Nozzle). Other available options on the Model A include a steel cover rather than a cast iron one (DA) and a fixed non-swivel nozzle (A5). In 1974, World Dryer was acquired by Beatrice Foods Co., and underwent a rebranding later that year, which saw the introduction of the current dark red "globe" logo. Also in 1974, World Dryer introduced a new hair dryer, called the Model B (later renamed the “Airstyle”), which features the same motor and assembly as the Model A, but the unit is flipped upside down (blowing air up instead of down) and has a longer 80-second timer.

In 1985, Beatrice Foods Co. spun off World Dryer as an independent company. Model As manufactured during Beatrice Foods Co.'s ownership of World Dryer from the mid-1970s to mid-1980s include the byline "A Division of Beatrice Foods Co" on their front labels. World Dryer sold their hand dryer model units to Bradley Corp with a modified version of their cast iron cover. In 1986, World Dryer introduced two new low-cost models, the NoTouch and the Airspeed. The NoTouch was the first automatic hand dryer. In 1987, World Dryer introduced an automatic version of the Model A, known as the XA, In 1992, World Dryer merged with the Electric-Aire Company. In 2000, World Dryer acquired Quebec-based Nova Hand Dryers, integrating its Nova line into its offerings. Beginning in 2005, World Dryer introduced several new models to compete against faster and more modern models that entered the market in the late 1990s and early 2000s, most notably the Dyson Airblade and the Xlerator from Excel Dryer, the latter of which had, by this time, overtaken the World Dryer Model A as the industry standard. The first of these was the AirMax in 2005, which is externally identical to the Model A Series, but is fitted with a larger, more powerful motor, drying a user's hands in 15 seconds. This was followed by the Airforce in 2008, the speed-adjustable SMARTdri in 2010, the ADA-compliant SLIMdri in 2011, the hands-in VMax in 2013, and the low-electricity VERDEdri in 2015. In 2017 World Dryer became part of Zurn Industries, and in 2022 with Zurn Industries merging with Elkay Manufacturing Company.

Worked examples

Example 1 — a first encounter with World Dryer

Start with the simplest possible case. Write down what World Dryer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to World Dryer before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about World Dryer ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of World Dryer

In research
World Dryer appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses World Dryer in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
World Dryer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950 establishments in Illinois, Companies based in Cook County, Illinois, Manufacturing companies based in Illinois, so understanding it makes those chapters shorter.
In everyday life
Look for World Dryer outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
