Research & Development

Bry-Air has always been in the forefront of technology and innovation through extensive R&D in moisture control, air treatment and optimisation of energy. Bry-Air’s efforts to introduce the best in class, energy smart technologies results in continuous R&D in designs, layouts, machinery and production methods which is integrated into the everyday work pattern. Research based development lends Bry-Air the leadership position it stands at today.

Bry-Air’s R&D facilities are recognized by the Department of Science and Technology and are  the best in the environment control industry, worldwide, in the corporate sector

Bry-Air, along with its associate group company, DRI…Desiccant Rotors International, flagship companies of the Pahwa Group, is the fastest growing Adsorption Technology group in the world today.

The R&D at Bry-Air focused to continuously provide the customer with Energy Smart green products through:

  • R&D on new technologies and materials as well as on controls and sensors
  • Design standardization through simulation, optimization and globalization
  • Innovative product and process development
  • Testing and certification of products

New Technologies Introduced Recently


The new, Bry-Air BrySmart Series (BBS) Dehumidifiers is embedded with patented BrySmart® and BryTherm™ technologies. The latest product offering from Bry-Air is designed for continuously optimizing Dynamic Specific Performance (DSP) and incorporates BHPTM (Bry-Air High Performance) rotor with special geometry and chemistry.

Integrating 4.0 tomorrow based concepts & technologies, BBS provides huge energy savings (upto 48% + additional 20%),  faster ROI and lowest cost of ownership. The technology is a step forward in energy conservation through enhanced automation (on real time). Read more


DryPurge desiccant dehumidifiers from Bry-Air is the most efficient and economical solution to provide dry air required for Lithium battery production. These engineered dehumidifiers incorporate the patented DryPurge® technology which ensure optimum performance of dehumidifiers, even at the ultra low dew point, up to (-) 90 ℃.

The Bry-Air’s DryPurge dehumidifier ensure recommended Dry Room conditions for lithium battery processing (proven success in meeting the stringent requirement of dew point lower than (-) 75 ℃, required by the most updated and largest lithium battery plant) and special grade coloured nylon blended PET bottles.

Adsorption Chillers – for energysmart cooling using waste heat

Bry-Air’s Adsorption Chiller harnesses the abundant low grade waste heat or solar heat available in process industries and solar plants and uses it for process cooling or air-conditioning (HVAC). It is available in the range of 11 kW to 1180 kW (3.1 TR to 335 TR).

Bry-Air has the latest and broadest spectrum of Adsorption Chillers available in the world. The energysmart cooling using waste heat is based on an advanced green technology and has inert Silica Gel (adsorbent) and Water (refrigerant) pair.  It helps cut cooling cost up to 99% and is ideal for industries like Power, Food & Beverages, Pulp and Paper, Solar, Chemical manufacturers, etc. and for Commercial areas like Offices, Buildings, Hotels, Malls, etc. Read more

BryWheel Dryer

The Industry 4.0 compliant generation next BryWheel rotor works on the principle of the Honeycomb technology which results in 25% more energy savings, 100% reliability and zero downtime. This ensures a much better control over dewpoint and temperature. This rotor is specially crafted for a very low dewpoint upto (-) 65°C.

Crafted for very low dewpoint upto (-) 65°C, the BWD series of dryers ensures a much better control over dewpoint,temperature and hence production process, even being far away. These dryers can be operated and controlled by a mobile phone, tablet or phablet. Read more

Research & Development Process

50 Years of Leadership in Adsorption Technologies

Bry-Air is the inventor of the Rotary Silica Gel Dehumidifier which is the forerunner of the fluted media based dehumidification technology

In 1964, substantial research and development activities were initiated to improve existing products and to develop new products. A unique laboratory was designed and constructed to serve two purposes:

Recent Technological Advancements and Breakthroughs

Recent TechnologiesRecent TechnologiesRecent Technologies

Our state-of-the-art R & D Lab is very versatile and is regularly used for the following

  • To simulate and optimize dynamic dehumidification variables for new product design and development
  • To standardize/establish ideal performance curve for desiccant products
  • To standardize /establish ideal performance curve of fluted media (honeycomb) products
  • To evaluate and certify the performance of granular desiccant. To evaluate and certify the performance of desiccant (honeycomb) wheel rotor.
  • To simulate and establish conditions for product drying at pilot scale for eventual full scale up.

Product Drying

To simulate conditions based on different environmental parameters to validate criteria for drying or storage of any product; e.g. products like Mushroom, Grapes or Tea can be spoiled due to over drying. The optimum conditions for drying such products can be simulated and validated in the Bry-Air dry chamber. Prototype development and bench marketing facility.

Test Facilities

Bry-Air along with its associate group company, DRI ..... Desiccant Rotors International has spent over 600 “man-years” of research in the field of rotors, to create the ideal honeycomb / fluted media and has setup a test facility to evaluate performance of EcoDry Desiccant Rotors. This Test facility is, perhaps, the best in the environment control industry today.

Desiccant testing facility

  • - To certify desiccant wheel performance
  • - To certify performance of desiccant
  • - To evaluate degradation quality of desiccant material of customers due to usage and pollutants
  • - To set criteria for vendors
