In addition to this, we are working on VOC concentrators and are also supplying NMP recovery solutions.

Automation enhancing the manufacturing process
The 4th industrial revolution is making its way into the manufacturing sector, giving rise to a phenomenon called ‘smart manufacturing.’ The process brings about the confluence of smart digital technology and manufacturing for flexible and versatile manufacturing. It is contributing to the realisation of real-time energy optimisation.

Using intelligent solutions like IoT helps exercise efficient control over the equipment and systems. Additionally, IoT-powered cloud services offer interactive interfaces to streamline various stakeholders in the same loop.

Consequently, this enhances manufacturing by harnessing the benefits of automation, machine learning, and real-time data. In this development, advanced technologies are enabling the production of efficient and sustainable products. Technologies like AI, big data, machine learning, robotics, cloud computing, etc., are transforming the manufacturing landscape. These enable every stage of the product cycle to be driven by unified information-driven decisions made in a factory environment. It has improved the efficiency from automating engineering processes to overseeing the business functioning.

In addition to all the advantages, it champions automatic management, rendering global quality products with minimalistic wastage of resources and acutely focusing on reducing customer claims while increasing user satisfaction.

Industrial dehumidifiers’ role in curbing manufacturing defects
India, at present, has a lot of potential and is emerging as the global manufacturing hub. As the country is eyeing the international market, it is crucial to manufacturing products of the highest quality. It necessitates manufacturers to always come up with new products and offerings to meet the end customers’ expectations with respect to quality, zero defects, and performance. This temperature regulation plays an imperative role in determining the quality of the goods. Temperature and Humidity control in most industrial processes go hand in hand and are defined as room conditions or process air conditions. This calls for integrated delivery demand from the Dehumidifiers. Therefore, in setting up a robust manufacturing infrastructure, industrial dehumidifiers will play an imperative role in curbing manufacturing defects and product malfunctioning occurring due to humidity.

Evaluation of temperature control in dry rooms
Considering that Li-ion battery manufacturing comes with many obligations to meet safety and quality standards, it is imperative to evaluate the temperature of the Dry Rooms. For instance, Dry Rooms need to maintain the RH at less than 1 percent and less than 10 percent in lithium cell manufacturing and battering assembling. It is required that the Dry Room maintain a shallow dew point, reaching up to -80 degrees Celsius for the ideal processing of hygroscopic and moisture-sensitive materials. Failing to comply with the required environmental conditions can impair the quality of batteries responsible for the inferior performance and, at times, can even give rise to serious safety issues with high chances of explosion. Therefore, evaluating the temperature of Dry Rooms emerges to be of utmost priority to produce quality batteries with the surety of unbeatable performance.

Present trends impacting the demand for your products and services
At present, the world is very enthusiastic about electric vehicles. Even India is actively participating in this transition to become the first EV nation by 2030. This drives the demand for dehumidification solutions critical for manufacturing highly efficient, superior-quality Li-ion batteries. Our Bry-Air Dry Rooms find application in this lithium battery production for providing complete Environment Control Equipment (Dehumidifiers). The dehumidifiers efficiently control moisture levels in the lithium-battery manufacturing areas from -40 °C to -80 °C dew point depending on the process being carried out that produces quality, safe and long-lasting batteries.

Apart from this, looking at the requirement for highly advanced technology, we have developed BrySmart® Series (BBS) Dehumidifiers to optimise energy consumption continuously. This eco-friendly dehumidifier is a step forward in energy conservation through advanced technology.

Likewise, in the plastic industry, we have launched Green Dry Smart Dryers to provide Waterless Plastic Drying solutions, considering the need for energy-efficient solutions in the industries like automobile, medical plastics, white goods, packaging, mobile accessories, sports/toy industry etc.
In the same way, the rate at which companies are undergoing digitisation which got fast-tracked during the pandemic, has given rise to the need for data centers in the recent past. This emerging sector heavily requires dehumidification solutions to arrest the micro corrosion menace due to moisture.

Opportunities and potential for industrial dehumidifiers
We at Bry-Air continually innovate and upgrade depending on the industry’s requirements. As technology progresses at a fast pace, we develop new product lines or modify our technology to match the evolving trends. We at Bry-Air have come up with the Green DryPurge (GDP) series for efficient dehumidification solutions for Li-ion battery manufacturing. With time, we introduced Low Dew Point (LDP) dehumidifiers to meet the requirement of energy-efficient Li-ion battery manufacturing requiring the shortest manufacturing time.

Similarly, we have customised and specially engineered P95°x Dehumidifier to cater to the pharmaceutical industry. It uses breakthrough rotor technology that enables unmatched performance and the benefit of unbeatable energy-saving capacity.

In the Compact Dehumidifier FFB series, we have developed FFB 4500 to provide an effective moisture control solution. It matches the ruggedness of industrial dehumidifiers, but at the same time, we customised it to meet the limited space constraints with the compact size that can be mounted on the ceiling to suit the proposition of a compact dehumidifier.
