Dehumidification, temperature control and ventilation services for comfortable working condition inside confined space
Safe Confined Area Access - Ventilation
What is a confined space?
Confined space means any place like tanks, columns, spheres, boilers, drums, chimneys, pipelines, cyclones, dust catchers, scrubbers, sulphur pits, ESP areas, kiln and other similar spaces, by virtue of its enclosed nature.
In confined areas, during maintenance and repair jobs like welding, fabrication, riveting job, strip lining, nozzle replacement, trays replacement are carried out, as a result, the air inside the confined areas becomes unhealthy and hazardous. Due to maintenance work and the presence of many people inside the confined area, the temperature increases to high levels approx. 48-500C with high relative humidity.
Also, the inherent danger of working in a confined space environment include:
Toxic, flammable, or explosive atmospheres
Harmful gas, fume, or vapour
Lack of oxygen
Excessively high temperature
Chemical exposures due to skin contact or ingestion as well as inhalation of ‘bad’ air.
With the depletion of oxygen in the air and more toxic fumes, it becomes difficult for workers to work inside the confined areas for a long duration. Consequently, they have to take breaks in regular intervals. Thus, the competence of the worker is affected, resulting in delays in the completion of the job and project. Also, toxic and flammable gases are injurious to the health of workers, engineers & the inspection team.
The temperature of the confined area should be between 32º – 35ºC
The relative humidity inside the confined area should be below 60%
Replenish oxygen at the correct amount of air change
Purging out toxic gases and replacing it with treated fresh air at the correct amount of air change
TDS provides customized dehumidification and temperature control systems to create the perfect working conditions inside the confined areas. Our package includes dehumidifiers, condensing units, blowers, and ducts backed by technical manpower to maintain the required relative humidity and temperatures inside the confined areas.
Desiccant based dehumidifiers adsorb the excess moisture from the air and maintain RH below 60%. At the same time, the condensing units help in maintaining the temperature between 25º-26ºC.
Improvement in productivity of the workers
Shutdown period is not extended hence reduced revenue loss
Timely completion of projects
Reduction of shutdown time resulting in tangible cost benefit
Health of the workers, inspectors, maintenance department, engineers is not affected.

Mr. Deepak Pahwa is the Chairman, Pahwa Group and Director of Technical Drying Services Asia. Pvt. Ltd. The group has 1500+ employees in 6 continents & 11 manufacturing plants.
In 1979, he set up the first company in the group, Arctic India Sales, introducing dehumidification in India. Subsequently, he set-up Technical Drying Services Asia, Desiccant Rotors International, Delair India and Technical Drying services.
An alumnus of IT-BHU, Mr. Pahwa has been honored with several awards, including the “Leadership Award 2013” by IACC for his dynamic leadership. He was also awarded a “National Award 2011 in Research & Development” in (Medium Enterprise) by MSME, the “IT-BHU Alumni Lifetime Achievement Award 2009-10”, and also the “Entrepreneur Of The Year Award” in 1987 in the SME entrepreneur category, to name just a few.
Mr. Pahwa is a Fellow, ASHRAE (American Society of Heating, Refrigeration and Air conditioning Engineers) and serves on several technical committees of ASHRAE. A life member of ASHRAE as well as ISHRAE, he has been recognized and honored by various industry associations for his contribution in enhancing India’s role in providing the best in the next class technologies from India to the world. He has also introduced many new technologies in field of dehumidification, IAQ and many others in India since 1979. He has played an active role in connecting the European Air-conditioning federation, REHVA, to the Indian industry.
Currently, he is the Chairman, Committee on Innovation, PHD Chamber and also serves on the Chamber’s Managing Committee. He has also served as the National President, Indo-American Chamber of Commerce. He has also served as the Convener, FICCI MSME Committee.
He is an advocate of collaborative work for advancing knowledge and works with the specialists, in the field of Adsorption and airgineering technologies, in the academia as well as the industry experts, not only from India but all over the world including Japan, Singapore, Korea, Turkey, Europe and USA.
With almost 50 years of experience in engineering & marketing of HVAC&R, Airgineering & Environmental Control Technologies, his success mantra is “Innovation is Life”. He believes that with the right amount of inspiration, encouragement and knowledge, ordinary people can achieve extraordinary work.
He has institutionalized innovation within the organization so that every employee learns to be an innovator and rewarded for their contribution
For the Society at large, Mr. Pahwa, taking inspiration from his grandfather, Padma Shri, Rai Bahadur Dr. Mathra Das Pahwa, a renowned Eye surgeon and a dedicated philanthropist, Mr. Pahwa has mandated through the group’s CSR initiatives work on providing education, skill development health & hygiene and opportunities in sports for enriching the lives of the underprivileged and differently abled. Another focus area is working towards environmental sustainability, both through the technologies being introduced as well the contributions and support provided to environmentalists.
