Short Term Drying

September 24, 2011

 

Drying is the process through which moisture is removed. Naturally drying is done by evaporating the water. Evaporation happens by air drying, sun drying, smoking or wind drying. But natural drying is not always convenient as the time duration required for the drying process cannot be controlled and has to be dependent on the environment.

Therefore industries basically utilizes dehumidification to carryout their drying process. Through dehumidification drying or the required moisture level can be controlled by the user as per need.

Drying is essential for industry because undesired moisture in the air can lead to:

  • Formation of rust and corrosion on steel structures.
  • Peeling or blistering of exterior paint. 
  • Pharmaceutical and Fertilizer  sector suffer from agglomeration of products.
  • FMCG industry faces problem during packaging.
  • Proper blasting and coating of steel structures are not possible.
  • Indoor air quality deteriorates.
  • Environment becomes conducive for mold/mild dew and fungus growth.
  • Damp spots on ceilings or inner surfaces of exterior walls. 
  • POP/Epoxy laying procedures gets elongated as proper drying is not possible when humidity is high.

Dry air is the solution to the above problem. But many a times drying requirements are seasonal it is required only in rainy season when the humidity is high or in case of petrochemical, power, fertilizer and sugar units in time of annual shutdown for maintenance. Short term drying is the solution for seasonal requirements as it helps in fulfilling the temporary drying needs.  

General Recommendation:

Short term drying through dehumidifiers is the most prevalent method among industries and it is the most recommended method. Dry air is provided through dehumidifiers to overcome the problems of rust, corrosion, fungal and packaging/storage problems. Through dehumidifcation excess moisture in the air is removed to have moisture free air. 

TDS Solution:

Technical Drying Services(TDS) provides short term drying services with the help of desiccant based dehumidifiers. The desiccant based dehumidifier removes moisture from the air by chemical attraction rather than condensation. Humid dry air is directed across a desiccant material that acts as a drying agent. The moisture is collected in the desiccant. The moist desiccant is dried using second hot air stream that heats the desiccant and releases the moisture. Then the desiccant is reused to provide more dry-air. In a continuous process the air is dried by the desiccant, at the same time the moist desiccant is dried for reuse so that dry air is available at all times continuously.

The main USP of TDS services is that it provides highly qualified technical manpower along with all the required equipments. As the service is provided on rental basis it can be availed whenever required.
