Munters

Munters is the industry leader using Zeolite Rotor Concentrators for low concentration VOC abatement. Munters employs a team of engineers to design the most suitable, low cost solution to your VOC abatement problem. We use our own HoneyCombe rotors with hydrophobic zeolites to adsorb and concentrate the VOC stream. The smaller, concentrated stream is then directed to your choice of thermal or catalytic oxidizer, RTO, recovery or alternate abatement system.

What is a VOC?

VOC stands for Volatile Organic Compound. Volatile chemicals produce vapours at room temperature. Organic is a chemical containing carbon atoms. Volatile Organic Compounds include industrial chemicals, solvents, alcohols, and also petroleum products such as  gasoline. VOC's combine with sunlight to form atmospheric ozone, or smog.

Zeolite is a naturally occurring mineral, in crystal form. Natural zeolite is made of hydrous aluminium silicates of sodium, calcium, potassium or barium ions.

Natural zeolite is hydrophilic (water loving) and readily adsorbs and desorbs water. More recently, synthetic zeolites have been developed for commercial applications. Over 70 types of synthetic zeolites have been created.

Hydrophobic zeolite is an inorganic, stable crystal with properties suited to adsorbing VOC’s. The zeolite's inert properties mean that it does not promote chemical reactions and will not even react with strong acids. It is also non-flammable to extreme temperatures.

The basic molecular structure of a zeolite is a tetrahedron or pyramid, formed by silicon oxides (SiOn). The tetrahedron has one silicon atom in the center and oxygen at each of the corners. The tetrahedral zeolites are linked together by oxygen atoms. Linked zeolites form pores, the size of which are determined by how many zeolite molecules are linked together.

Depending of the number of linkages and which alkali ions are present in the crystal structure, several types of zeolites are formed, all with different pore sizes. The size of the pores also determines which VOC’s can be adsorbed.

Munters Zeol uses a mixture of hydrophobic zeolites with different pore sizes. This mixture allows a wide range of organic solvents to be adsorbed. In fact, most commercially available solvents are adsorbed by these hydrophobic zeolites.

A VOC is attracted and held in the zeolite pore by a weak attractive force. This weak physical attractive force between chemically neutral compounds is known as the van der Waals force. The VOC will remain in the pore until it heated, at which time the VOC will be released from the zeolite into the air.

When VOC laden air flows past zeolite molecules, the zeolite acts as a reverse filter or molecular sieve, capturing the compounds which are able to adsorb and allowing the compounds that are too large to flow past.

Munters Zeol combined the hydrophobic zeolite technology with its HoneyCombe rotor technology. A system was created that can operate continuously with constant adsorption and desorption, has a low pressure drop, and maximized the surface area. One square foot of HoneyCombe media has a surface area of 492,480 ft2 ( 45,753 m2).

HoneyCombe rotors were developed over 40 years ago by Munters. Munters is the world’s leading supplier of process systems using HoneyCombe rotors for dehumidification, heat exchange, and VOC abatement. Munters’ HoneyCombe rotors have numerous benefits. Rotors allow for high air flow, truly continuous operation. With a low pressure drop rotors have stable outlet conditions. The hydrophobic zeolite is permanently bonded with the HoneyCombe rotor therefore no attrition of the zeolite occurs.

Munters HoneyCombe rotors are manufactured at the ISO 9001 certified facility in Amesbury, Massachusetts. The rotors are manufactured from a corrugated mineral fiber substrate permanently bonded with a proprietary mixture of hydrophobic zeolite and inorganic materials. The hydrophobic zeolite rotor is inorganic, completely inert and has rigidity, physical integrity and the ability to withstand thermal stress. The permanently bonded hydrophobic zeolite is an integral part of the HoneyCombe matrix and will not be leached out or removed physically or chemically.

As a low concentration VOC laden air stream enters the hydrophobic Zeolite HoneyCombe rotor the air passes through the HoneyCombe media. The rotor turns several revolutions per hour continuously transporting VOC laden zeolite back into the regeneration sector and regenerated zeolite into the process section. In the process section the VOCs are adsorbed onto the zeolite and the clean air is exhausted to the atmosphere.

In an isolated section, a small, hot stream of clean air is drawn through the rotor. This stream is normally only 5–10% of the process volume. The hot air desorbs the VOCs from the zeolite forming a concentrated VOC laden air stream. The regenerated zeolite is returned to the process.

The concentrated stream is sent to a small oxidizer. The oxidizer converts the VOCs to carbon dioxide and water vapor which are exhausted to the atmosphere.

The energy content of the VOCs contributes to the oxidation process further reducing the fuel requirement.

The concentrated VOC stream can also be sent to alternate technologies, such as a condenser which recovers the VOCs for potential reuse, or a biofilter.

Munters’ Sustainability Agenda

Sustainability is a fundamental part of Munters’ long-term strategy and value creation. To verify that our strategic priorities in the field of sustainability are correct, we get information and draw inspiration via various channels. For example, we monitor which macro-trends – both long and short-term – are the most important. Another source of valuable information is monitoring the work of the UN and other countries around Agenda 2030. We communicate continually with our most important stakeholders – business partners, employees, and the capital market – in order to understand which issues they are prioritizing in the field of sustainability.

Based on the materiality analysis, we have defined Munters’ Sustainability Agenda, and in 2017 we began the work on setting goals, activities, and metrics for our eight areas of focus. This work will continue throughout 2018.

Initially, we chose to prioritize the work on the focus areas connected to the parts of the value chain where we feel we have the greatest possibility of exerting our own influence, such as product development, sourcing, sales through own employees and own manufacturing.

There are other areas in the value chain where we have less possibility of direct influence, for example, how the customer uses and recycles the product, and transportation – especially when customers or suppliers are responsible for it. These areas are also important, in order for us to be able to reduce the environmental impact of our operations, and we will therefore work further on also setting goals, activities, and metrics in these areas.

Our Brand Promise is “Your Perfect Climate”. How do we then go about fulfilling this high-aspiring promise?

The foundation for all we do in Munters is our very strong set of Core Values. The primary one is “Sustainable Value Creation”. We must always consider the things we do and how they make Munters a continually better company. We all work here for a short time – as compared to the time before us and the time after us. While we work for Munters we must focus on making our customers more pleased, our employees more engaged, our owners satisfied and also ensure that our surrounding society becomes a better place. We must leave the company in a better place than it was when we joined Munters.

We are also convinced that people enjoy working in a place where they experience personal growth through solving problems together with other talent. This is why our second Core Value is “Team Spirit”. We take pride in employing great people with a high level of competence. But only individual capability does not take you very far, it is absolutely necessary to work together in teams.

Because we will jeopardize our third Core Value if we do not work in Teams. This value is “Passion for Results”. We are of course not only thinking about our financial result, although we naturally keep a close eye on this. But results are also more qualitative, such as Customer or Employee Satisfaction. It is operational efficiency such as On Time Deliveries. It is developing new products on time and budget. It is providing our employees with learning opportunities to meet their development needs. All employees in Munters have clear goals – that is how we maintain our focus on results.

And our fourth Core Value is the natural extension of our result orientation. Because when we have achieved the level we want to reach, then we want to become better. This is how we always try to stay ahead of competition, of being the preferred partner to all with whom we work. We believe strongly that “There is always a better way”; a way to improve what at first may look like the perfect way. We are convinced that if employees every day look at what they do and think “there is probably a better way to do this”, we will always have an advantage on competition. Because how does our competition catch us if we are always moving further ahead?
