– Munters’ desiccant rotor – industrial dehumidification at its best

Munters desiccant rotor

In 1951, Carl Munters filed a patent for a desiccant-based drying system for cold storage rooms. He clearly realized the potential of the silica gel’s ability to reduce moisture.

Nearly a thousand patents later, his legacy is still at the heart of Munters’ dehumidification technology. Today, Carl Munters’ groundbreaking discoveries have been refined into a range of desiccant rotors that can remove moisture from virtually any indoor environment around the clock, every day of the year.

The concept is very simple: Air is blown through the rotor frame and the humidity is adsorbed by the impregnated media inside the frame. The process results in drier air.

The rotors are part of Munters’ desiccant dehumidification systems used to control the humidity of commercial buildings and industrial processes. Humidity control has a wide range of benefits, such as corrosion prevention, reduced microbial growth (mold, bacteria, etc.), condensation removal and improved human comfort. Due to the myriad benefits of humidity regulation, more than 20 major industries benefit from these systems, ranging from supermarkets and pharmaceuticals to electronics manufacturing and food processing.

A cheaper way to dry wet air

Industrial dehumidification systems have become increasingly popular in recent years due to lower total costs through economies of scale, modular designs and excellent reliability. The systems are also very energy efficient and Munters is constantly striving to make its solutions even more environmentally friendly by using waste heat from available sources, such as condensers, to dry the desiccant wheel.

However, efficiency, reliability and cost-effectiveness have become standard features in a competitive market. Munters therefore continues to push the boundaries and improves its rotors so that other factors such as the operators’ health, safety and hygiene are also covered. For example, the rotors are regularly tested by independent bodies, such as the Swedish Institute for Food and Biotechnology, to confirm their innate bactericidal and fungicidal properties.

At Munters we have a saying: “There is always a better way”, but ironically we have not found a better way to dry air than with desiccant rotors. Sometimes a original idea that was patented back in 1951 turns out to be the best way after all.
