What makes Vindon Stability Technology different?
Vindon stability storage rooms, and the engineering techniques used in their manufacture, have been honed and perfected over the 40 years of Vindon Scientific's industry experience.
Humidity control
Vindon Stability chambers use TDK ultrasonic transducers to produce humidity. When humidity is needed, a metal plate vibrates creating a focused beam energizing the water molecules just below the water surface. A 'cloud' of water droplets then form just at the surface. Air is then taken from the chamber, mixes with the vapor cloud for humidity, and is reintroduced into the chamber.
Benefits include:
- Ultrasonic transducers run only when humidity is needed reducing cost of energy
- Humidity is generated immediately when needed.
- With no heat output from the system, the need for extra cooling is reduced
- Humidity generation is terminated immediately when room equilibrates De-humidification option to 15%RH and below is possible with the addition of a desiccant dryer.
Temperature control
For applications requiring operating temperatures above 10ºC, an indirect refrigeration system is recommended. Unlike a direct system where the refrigerator evaporator is located in the room and runs at sub zero temperatures, our indirect system simply uses water as the coolant passing through a coil located in the chamber. The water is cooled by a refrigeration system, using R134A refrigerant, with the temperature set just below the dew point of the room. This results in less power being used by the heaters and also acts as a balance to provide extra control of the humidity level inside the room. .
Benefits include:
- No ice up and, therefore, no need for defrost cycles
- Close matching of surface temperature to dew point of internal air for greater humidity control
- Requires less energy from heater to offset cold air For applications requiring temperatures below +10ºC but above 0ºC, the type of refrigeration system will be selected to suit the particular requirement.
Energy consumption
With a combination of indirect cooling and ultrasonic transducers for temperature and humidity control, we are able to realize significant savings on energy cost.
Vindon stability storage rooms and chambers require significantly less energy draw than other stability storage rooms and chambers available on the market, while maintaining a very stable environment.
Shelving
We use perforated grade 304 solid stainless steel for all of our shelves to give a sturdy flat smooth surface and ensure optimum air movement throughout the chamber for the most uniform conditions.
The height of every perforated shelf is easily adjusted without the need for any tools. Other options available including plastic coated or stainless steel wire shelving.
The design and manufacture of all Vindon Stability Storage chambers is geared towards reduced energy usage and therefore lower cost of ownership.
