Munters Zeol System | How the System Works | Advanced Design | Munters Zeol Brochure

Sixty Years of Excellence and Innovation With the combination of breakthrough zeolite research and time-tested Munters rotor technology, the systems have introduced a new level of efficiency and effectiveness to VOC abatement. Continuous research and engineering has lead Munters to its current dominant position in the field.
Munters Zeol is a division of Munters Corporation, a sixty year old air treatment technology company, headquartered in tockholm, Sweden. The company’s founder, Carl Munters, was a renowned 20th century inventor who many consider the “Edison of weden.”
Among his accomplishments were the development of the first home refrigerator and the substance now marketed widely as “Styrofoam.” Before his death in 1989, Munters had earned nearly 1000 patents.
The company that now bears his name has operations on six continents. Munters began its American operations in the 1950s, manufacturing products for humidification and dehumidification. Since then, Munters has grown to be the worldwide market leader in air treatment technologies.

Today, our lives are impacted by Munters technology in a myriad of ways. Our products fight pollution, speed manufacturing, improve building comfort, increase agricultural production and help people recover from disasters.
In each case, Munters products improve or control the quality of air. Our success is based on leadership, technology, solutions-oriented engineering and a dedication to product quality.

Unparalleled Experience Munters is the industry leader in zeolite rotor concentrator systems having hundreds of installed systems. We pioneered the commercial use of zeolite for adsorption of VOCs.

Rotor Technology and Production All engineering and manufacturing activities take place in our ISO 9001 certified factory. This is the only facility in the world that controls all aspects of rotor concentrator system manufacturing including the HoneyCombe® rotor structure and assembly of complete VOC abatement systems. We continuously work on product improvements and advancements in zeolite rotor technology.

Low Cost of Ownership Munters concentrator systems have lower operating costs than RTOs and recuperative oxidizers. Less natural gas is required, and the low pressure drop across the system equates to smaller fans and lower electrical costs.

Reliability Munters systems are engineered to operate continuously. Maintenance downtime is one day per year allowing customers to maximize production.

Turnkey Systems Munters turnkey solutions include system design, installation services, project management, construction supervision and commissioning.

Engineered Retrofits Munters can retrofit your existing system to increase capacity, improve performance and greatly reduce energy consumption. We also custom fabricate zeolite blocks for replacement of carbon rotor systems.

Modular Design Munters systems are factory pre-wired, skid mounted and factory tested ready for installation and startup. Our modular design provides flexible configurations and minimizes lead time.

Worldwide Service Munters service division offers comprehensive preventive maintenance programs. Our highly trained service
personnel are available 24 hours a day worldwide.

Solvent laden air is drawn through the HoneyCombe rotor where VOCs are removed from the airstream by adsorption onto the hydrophobic zeolite. After passing through the rotor, the cleaned air is discharged into the atmosphere. The Zeol rotor turns continuously (1-6 rph) transporting adsorbed VOCs into a regeneration zone. There, the VOCs are removed by a small heated
air stream that is 5-10% of the process air volume. The regenerated zeolite is then rotated back into the process air stream.
The concentrate is typically sent to a small oxidizer where the VOCs are converted to water vapor and CO2.

The energy content of the VOCs contributes to the oxidation process further reducing the fuel requirement.
Heat exchangers are used to pre-heat the concentrate and provide the required heat needed to desorb the rotor and create additional fuel efficiency. Hydrophobic Zeolites Munters proprietary zeolite offers several characteristics that are ideal for VOC
abatement. Hydrophobic Properties Munters zeolite is made hydrophobic using a chemical process that replaces the aluminum in the crystal with silicon atoms. Since it repels water, it is unlike any other zeolite, synthetic or natural. This property allows the zeolite to use all of its pores to attract and hold VOC molecules from an air stream. Non-flammable Properties As an inert and stable inorganic crystal, it does not react with organic materials or exhibit catalytic properties. This allows use of high temperatures for desorption of high boiling compounds and eliminates the safety risk associated with carbon adsorbers.
Pore Sizes Zeolite pore size determines which molecule the zeolite will attract. Munters uses a proprietary mixture of
zeolites with pore sizes to cover a wide range of organic solvents.
Adsorptive Capacity At low inlet VOC concentrations, zeolite has a higher capacity to adsorb VOCs than comparative technologies. (see Chart A) At high relative humidities, zeolite adsorbs less water than carbon (see Chart B) leaving more sites for adsorption of organic molecules. Carbon experiences loss of adsorbent efficiency at 50% RH, whereas Munters zeolite remains efficient up to 90% relative humidity.

Zeolite HoneyCombe rotors are manufactured from a corrugated mineral fiber substrate treated with a proprietary zeolite and other inorganic materials to provide physical integrity, rigidity and enough flexibility to withstand thermal stress. The HoneyCombe rotor, capable of withstanding 1,100°F is not affected by corrosive substances such as strong acid and is not blocked by high boiling solvents, particulates or resinous materials. Air flow through the flutes is uniform and of low velocity, resulting in very low pressure drop (less than 1.5” w.c.). It has continuous operation, non-fluctuating outlet conditions with no adsorbent attrition and few moving parts. The rotor has low friction contact seals to prevent leakage.

Munters custom fabricates replacement zeolite blocks for any existing carbon or zeolite concentrator
system. The drive motor is explosion proof, inverter duty, UL listed and can be manually adjusted
with a speed controller.
