More Information

  • The science behind ReNew:
    - It is a new type of de-humidifier that is greener, more compact, more efficient, and less costly to operate than other traditional products on the market today. It gains these advantages because it eliminates the need for a fan and the use of a desiccant. It is quiet and has no moving part. It simply uses gentle dry heat and a powerful air convection current to remove moisture and refresh hearing instruments
    - Traditional de-humidifier uses a small heating element and a fan to distribute the heat into the chamber. In contrast, ReNew uses a large aluminum heater to generate gentle dry heat
    - The heating element is housed on a large piece of industrial grade aluminum plate that measures approximately 59 mm (wide) x 113 mm (Long) x 3 mm (thick). Since aluminum is an excellent heat conductor, it distributes heat evenly across its entire surface without the need for a fan. This heated aluminum plate is placed slightly below the chamber so warm air can rise into it. This ensures heating consistency and uniformity
    - A precision electronic temperature controller maintains a constant 45°C / 113°F inside the chamber. This gentle dry heat evaporates surface moisture or condensate on the hearing aids. The 20°C temperature gradient (difference) between the chamber and outside (25°C) creates a powerful air convection current that drives resultant moist, warm air outside via the small openings on top
    - Simultaneously, cooler and drier room air is being drawn back in via the bottom inlets and warmed by the aluminum plate before entering the chamber
    - Computer-aided design and analysis techniques were used to optimize both inlet and outlet openings for maximum air convection current. This dynamic action is constantly repeating until the selected timer setting is reached
    - It shuts off automatically at the end of the timer setting. ReNew offers three timer settings (2, 4, or 8 hours) for optimal control and energy saving. The 4-hour setting is more than adequate even for the most demanding location such as a summer home in Florida or Hawaii
    - The amount of energy consumed by ReNew is extremely small, it only consumes 48 watt-hours of energy during the entire 4-hour period. This is less than that consumed by a 60 watt bulb in 1-hour. At an average electricity rate of 13 cents per KW-hour, ReNew costs less than a penny per usage. This is much less costly than the use of a desiccant which must be replaced on a regular basis
    - ReNew is about 30% smaller than other devices, and is made of high-impact polycarbonate plastic (bullet-proof window material)
    - It is extremely durable and can withstand numerous drops from a nightstand or table. It boasts a large heating chamber and can accept two sets of hearing-aids for fast, even drying. Its compact power adapter can be stored inside the chamber when traveling
    - It is compatible with all international electrical systems (Asia, Africa, Europe, North and South America). All thats needed is the appropriate local plug adapter
  • How it Works:
    - Room air enters via bottom inlets of ReNew
    - Room air is warmed by aluminum heating plate and then rises into chamber; warm air in chamber evaporates hearing aid moisture
    - Temperature gradient between chamber and outside creates a powerful convection current that drives resultant moist, warm air outside. Purged air is then dispersed by normal air circulation in the house
  • Built-in battery tester:
    - ReNew is the only de-humidifier with a built-in battery tester. It provides a simple and reliable method of testing a battery before replacing. This saves money by eliminating the waste of good batteries. A user simply presses a battery against the two gold contacts on the tester to get a quick reading on the condition of the battery. Four or five-bar indication means the battery is good while one or two-bar means the battery is marginal, and should be changed before going out. 
  • UV light:
    - Two UV lights are provided in the heating chamber. They sanitize hearing aids and provides similar beneficial effect as UV light in sunlight. An independent ON / OFF control is provided for its operation. 
  • Magnetic latch cover:
    ReNew uses a magnetic latch cover, and it can be open or close using one hand. Very little hand dexterity is required to open or close. It is a great relief for someone who has arthritis. Magnetic parking for batteries: Another unique feature is its magnetic parking spot for keeping the batteries at one place. Although we recommend leaving the battery in the hearing aid while using ReNew (with battery cover open for air circulation). Some users prefers to take the batteries out and placing them on a nightstand overnight. Unfortunately, batteries tends to disappeared from the nightstand the next morning. This magnetic parking spot is an elegant solution to a common problem.
  • Important Safety Instructions:
    When using electric appliances, basic precautions should always be followed, including the follawing:
    - Read all the instructions before using the appliance
    - To reduce the risk of injury, close supervision is necessary when an appliance is used near children
    - Do not look directly at the 2 UV lights located on the front corners of the drying chamber
    - Only use attachments recommended or sold by the manufacturer
    - Do not use outdoors
    - Do not use near water
    - To disconnect, turn all controls to the off position, then remove plug from the outlet
    - Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord
    - Unplug from outlet when not in use and before servicing or cleaning
    - Do not operate any appliance with a damaged cord or plug, or after the appliance malfunctions or is dropped or damaged in any manner.
    - Return appliance to the nearest authorized service facility for examination, repair, or electrical or mechanical adjustment
