Hand dryers are electrically operated components built to efficiently dry hands after washing. Old models typically have a downward-facing vent where users place their hands to be dried. Modern hands-in dryers feature an innovative design with openings that allow users to insert their hands, enabling air to flow and dry all sides of their hands. They fall into two major categories: hot-air dryers, which use warm air for slower drying, and high-speed dryers, also known as jet air dryers, which rely on fast, concentrated air streams to remove water efficiently without rubbing the hands.
Moreover, the hygiene implications of hand dryers remain a topic of concern. Research conducted on the comparison of hand dryers to paper towels proposes that bacterial counts may rise with hand dryers while reducing with paper towels. Overall, these drying components can be beneficial in terms of time and cost saving, providing effective drying performance without taking much time.
How Do Hand Dryers Functions?
At an early age, hand dryers used a heating element to produce hot air that would evapourate the water from the user’s hands. Today, modern hair dryers come equipped with an infrared sensor that detects hand movement, which in turn triggers the hand dryer to produce warm air. This hand-drying approach is very energy-saving as it only works when needed. The latest hand dryer models prevent users from touching the dryer, which reduces the risk of bacteria spreading.
What are the Typical Uses of Hand Dryers?
Hand dryers have become a ubiquitous fixture in public restrooms worldwide. From bustling airports and train stations to local cafes and shopping malls. Some of the most common applications include:
- Shopping Malls: Used in shopping centres where high footfall is common.
- Medical Facilities: A hand-under dryer is suitable for patients with disabilities.
- Educational Institutes: Typically installed at a lower height in schools so that children can be easily accessible.
- Restaurants and Cafes: Used in edible spaces to facilitate customer hygiene.
- Events: In events where a substantial number of people attend the restroom simultaneously.
- Workplaces: Critical for businesses of all sizes to ensure employee hygiene.
What are the Potential Advantages of Using Our Best-in-Class Hand Dryers
- Lowers the spread of germs and bacteria than paper towels.
- Minimises paper waste and reduces the environmental impact.
- Lower long-term costs due to minimised paper towel usage.
- Many modern hand dryers are built to be energy efficient.
- Sleek and modern layout enhance the overall look of a restroom.
Available Hand Dryer Types
The two major types of hand dryers are listed below:
- Jet Air Dryers: Features robust fans to expel high-velocity jets of warm air to dry hands rapidly. They are cost-saving and reduce the risk of bacterial transfer.
- Warm Air Dryers: This type of hand dryer uses a blow fan to blow warm air on hands. Warm air dryers provide a quiet operation, which makes them perfect for noise-sensitive environments. However, they may take longer to dry hands than jet air dryers.
