Dew Formation Chamber/Dew Test Chamber

The Dew Formation Chamber is designed to stimulate temperatures of the sample specimens below the dew point of air and is most commonly employed for plant pathology studies. They maintainhigh humidity levels within the working area therefore allowing the formation of dew and helps in understanding the plant pathogenesis. These Dew Test Chamber feature unique and advanced self-contained air-cooled condensing unit that ensures precise temperature control by alternately cycling refrigerant and hot gas to the coil.

The dew condensation on plant surfaces creates an ideal environment for development of plant diseases and facilitates the germination of dormant fungal spores present in the air leading to infection and outbreak of diseases. Dew condensation is also a major cause of deterioration in buildings and homes and is particularly hazardous for the electronics items and components as it causes numerous problems in the product such as ion migration and can often lead to malfunction and breakdown of the electronic equipment. By simulating a natural humid environment, these chambers facilitate the study of plant diseases, providing a better understanding of the mechanism of infection and disease pathogenesis. Apart from study of plant diseases, these equipments also help in testing the stability and shelf life of electrical items, resistance of paints and coatings and study of other manufactured goods and industrial products.

Special Features:

• The test chamber uses special plates mounted on side walls for capturing the excess heat radiated by the samples.
• Cooling plates come without fans to prevent the spreading of adherent fungal spores within the equipment.
• False ceiling of these dew test chambers is tapered to prevent the water droplets from settling on the plant surfaces on the top shelf.
• HMI+PLC based controls.
• Color touch panel
• Less use of Electrical and Mechanical Components on the Top and Bottom of Chamber - Provides easy maintenance of chamber, increases durability because of proper air circulation; cooling systems kept at bottom of the chamber to provide proper environment for compressor.
• Circulation Fan with Variable Speed -
  
  • Electrical efficiency
    Variable speed motor saves money by reducing energy bills, as it consumes less electricity than conventional motor.
  • Cooling Efficiency
    Variable speed enables gaining air conditioning efficiency or SEER.
  • Air Quality
    Variable speed motor helps clean the air efficiently. When the fan is in constant operation (indicated by the "Fan" setting on thermostat), the motor continues to slowly circulate air, allowing filters to capture more contaminants.
  • Humidity Control
    Variable speed motor combined with a Thermostat allows controlling the amount of humidity.
  • Quieter Operation
    Variable speed blower motor are significantly quieter thanits single-speed counterpart.
• Air Cooled Refrigerated System - Air cooled refrigeration system offer various benefits like
  
  • low fan power consumption
  • resistant to corrosion and freezing conditions
  • requires very low maintenance
  • Guaranteed long life operation
