Munters, established over 65 years ago and with over 3,000 employees in 30 offices worldwide, is the global leader in energy-efficient climate control. Munters provides temperature and humidity climate solutions to assist the manufacture and storage of products, and create comfortable indoor environments. With more than 300,000 installations worldwide, Munters possesses a unique experience that is used to constantly improve and further develop the wide range of products for creating Your Perfect Climate.
In all processes involving ingredients, a precise control of humidity is a must. Climate conditions vary over the year and in periods with high humidity and/or temperatures both product quality and production efficiency will be negatively affected. Munters supplies humidity-controlling dehumidification solutions for any production process where ingredients are naturally exposed to high humidity.
When hygroscopic ingredients and powders absorb moisture they become sticky and build up inside silos and conveying lines. The resulting flow problems slow the process, create sanitation concerns and eventually cause costly downtime.
During storage in silos the difference in temperature (outside/inside the silo) will lead to condensation on the upper inside of the silo. The stored ingredients will be exposed to condensation dripping onto the product, thus compromising hygiene. Growth of mould is unavoidable when condensation appears and, combined with the contaminating condensation dripping, the risk of affecting the product quality increases instantaneously. Exactly the same problems occur when ingredients are in haulage. Transporters face flow problems that delay both loading and unloading, and result in product waste, frequent need of cleaning and product-quality-related issues.
Drying processes are sensitive processes that require close attention to both temperature and humidity control. Drying in spray towers and fluid-bed systems often requires pre-cooling to deal with the moisture load and the wet surfaces can cause hygienic concerns.
Munters' air treatment technology creates the best conditions for product drying, conveying, tabletting, milling, mixing, packing, freezing and storing raw materials and final products. This guarantees consistent quality, significant energy cost savings and increased throughput. Simply by mastering the temperature and humidity of the ambient air, it is possible to achieve significant cost savings and quality improvements. The key is to control the air quality surrounding the production process with Munters' air treatment systems that is designed around a desiccant dehumidifier.
Many high-volume manufacturing companies receive their ingredients by truck or by rail. Pre-drying the air used in their pneumatic conveying ensures that products are transported dry into the silos. Furthermore, the same dehumidified air used for conveying can be delivered into the silo or hopper, and will not cause the ingredients inside to solidify.
On silos, a desiccant dehumidifier will supply dry air to the top of the silo whereby the air above the product stored in the silo will be kept dry - avoiding the risk of condensation and bacterial growth. For ingredients in haulage the dry air will be introduced into the container from a small dehumidifier mounted on the vehicle. Controlling the humidity to be constantly below the dewpoint in the silo/tank will automatically eliminate the risk of condensation and the following problems.
Munters air treatment systems reduce:
Outdoor winter conditions with a low absolute humidity provide an ideal production climate for processes like drying of ingredients. In summer conditions however processes such as spray drying are adversely affected by the increased humidity levels, creating multiple problems associated with condensation.
Leave it to Munters to mimic the winter conditions and thereby create stable conditions all year round - your guarantee for reliable quality and less waste.
By fully controlling the relative humidity, condensation can be prevented and the growth of mould and fungus is greatly reduced. As part of a coordinated programme, this can help to satisfy the requirements of today's strict hygienic regulations. Furthermore, the constant climate around the year makes production more reliable and fully predictable.
For product drying processes Munters has developed the Quantum™ rotor that has an extraordinarily high DeltaX. That eliminates the need for pre-cooling, thereby solving hygiene problems related to the presence of wet surfaces.
Munters' patented innovative air treatment systems give faster productivity and thanks to desiccant wheels (rotors) that are independently proven to be both bactericidal and fungicidal, a high level of hygiene that will support compliance with HACCP regulations and GMP certification.
The basic principle of desiccant dehumidification developed by Carl Munters more than 60 years back is still the most efficient drying technique known today.
Like most good ideas, Munters dehumidification principle is basically simple. Functioning without any cooling coils, Munters desiccant dehumidifiers use no CFCs, HCFCs or gases linked with ozone depletion.
By optimising rotor material and the control of the desiccant rotor, Munters is able to improve dehumidification capacity and reduce energy consumption.
The Quantum™ rotor and internal rotor heat recovery systems are examples of Munters' environmentally friendly thinking, resulting in higher production capacity and lower energy bills.
