With so many technological advances around, it’s hard to believe that some industries still use outdated manual processes to carry out crucial and sometimes life-dependent tasks such as transporting temperature-sensitive items.

Consider this: Traditional refrigeration and cooling systems rely heavily on compressors and chlorofluorocarbons (CFC) gases. These systems are energy-intensive and pose significant environmental challenges, contributing to greenhouse gas emissions. Not to mention, they are not easily portable, which leaves the cold chain industry relying on ice packs and gel-based insulation boxes to transport temperature-sensitive drugs.

So what is the solution? Invensify, led by founder and CEO Faizan Ahmed, has developed an alternative. Instead of using these traditional methods, their product, Insuridge, uses semiconductor technology to keep things cool. This means more reliable temperature control, less waste and a greener way to transport medicine and other essentials.

“If you’ve ever looked at the back of a traditional fridge, you’ll see compressors, CFC gas and coils – a lot of mechanics and fluids working together. What we’ve done is miniaturize all of that into a single chip, simplifying the cooling process. No more CFC gas, compressors or coils; it’s now just one solid-state chip cooling the fridge,” explains Ahmed.

By moving away from compressor-dependent models, Invensify significantly reduces energy consumption and greenhouse gas emissions, aligning with global efforts to combat climate change. Its product is not only quieter but also more durable and versatile, opening up possibilities for use in applications where traditional cooling methods are impractical or too cumbersome.

Invensify’s journey began with a personal problem. While traveling with his diabetic father, Faizan saw firsthand how difficult it was to maintain a stable, cool temperature for insulin using traditional ice packs. With a background in electrical engineering and solid-state physics, Faizan decided to create a more reliable and portable refrigeration solution. He recalls, “I started thinking, why is there no reliable solution to transport temperature-sensitive materials? Why are we still relying on ice? That led me to focus my attention on developing a portable system that could be used for transporting drugs and other materials. That led to Invensify.”

One of the standout features of Invensify’s technology is its energy efficiency. Operating on a compact 30Wh internal battery, Insuridge can maintain a consistent temperature for up to five days without requiring an external power source.

“These portable refrigeration systems are essentially plug-and-play. Simply plug them into a wall outlet, and they begin cooling the payload. Within five hours, the temperature drops to 2°C. Once unplugged, the unit maintains temperatures between 2°C and 8°C for up to 5 days using the internal battery,” explains Ahmed.

In addition to its power efficiency, Insuridge is also connected to the Internet, providing real-time tracking capabilities. Each unit is equipped with GPS and LTE connectivity, allowing users to monitor temperature conditions remotely via a cloud-based platform.

Invensify has strategically positioned itself to cater to both business-to-business (B2B) and consumer markets. Initially, the company focused on B2B clients, establishing partnerships with pharmaceutical and logistics companies. Looking forward, the company plans to enter the consumer market within the next six months by introducing a smaller, portable unit. This unit, designed for individual use, will enable consumers to safely store medications like insulin while traveling, directly addressing the personal struggle that inspired Faizan to start the company.

Invensify’s vision extends far beyond the pharmaceutical cold chain. Faizan envisions a future where their solid-state technology can cool AI chips. As artificial intelligence processors generate tremendous heat, Invensify’s compressor-free system could replace the current water-cooling methods.

The company also sees opportunities in the electric vehicle (EV) market. Currently, EV batteries are prone to overheating, which can limit their charge capacity and longevity. By integrating Invensify’s solid-state cooling technology, EV manufacturers could improve charging speeds and battery life, addressing some of the key concerns surrounding these vehicles.

“Our vision for the future is very simple. We’re in the business of creating power-efficient cooling systems,” says Ahmed. “We want to create a paradigm shift and become a company that is going to reshape how cooling is going to be done in the future.”

Invensify is on a mission to modernize the cooling industry, creating solutions that benefit industries and consumers alike. The company’s focus on developing power-efficient, compressor-free cooling systems is already changing industries such as logistics and healthcare – and it’s only the beginning.
