When dealing with delicate substances or temperature-sensitive products, or working in confined spaces companies must take care to take proper temperature control measures in their facilities. In order to properly control a facility's warmth and cooling ranges, temperature control systems are a must for any business or company. Temperature control is vital in a variety of different fields. For instance, temperature control systems are used to monitor the pre-heating of industrialized welding projects, or to regulate per-cooling of confined spaces like columns/vessels & reactors.

Pressure vessels in industries needs time to cool down as result of which worker cannot carry out the maintenance activities and the process gets delayed.

In petrochemical and sugar units,fertilizer and power plants annual shutdown takes place for the purpose of carrying out maintenance activities. Precooling services becomes essential at this stage because if the equipments like columns, tanks, boilers and reactors etc are allowed to cool on their own it takes very long and precious man hour gets wasted.   

During the time of maintenance-coating, painting, fabrication and other hot jobs are carried out as a result of which toxic gases are produced which affects the health of the workers &  inspection/maintenance team.     

General Recommendation:

Proper ventilation services is the answer to all the temperature and toxic gas related problems.

Temperature control services through condensing units,dehumidifiers,plenums and ducts is the most recommended method. Dehumidifiers and condensing unit combination can provide the level of temperature and humidity as per requirement. Impure contaminated air inside the vessel can be flushed out and fresh dry air can be provided to create comfortable working condition.

TDS Solution:

Technical Drying Services (TDS) provides temperature control services with the help of desiccant based dehumidifiers & condensing units. Fresh dehumidified, clean air at desired RH and temperature is provided by extracting the impure air from the inside environment. The desiccant based dehumidifier removes moisture from the air by chemical attraction rather than condensation. Impure air is directed across a desiccant material that acts as a drying agent.

The moisture & other impurities are 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 dehumidification 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.
