Several manufacturing or processing processes require a controlled relative air humidity value to ensure that treated materials or substances are modified by the water particles contained in the air. Some examples include the processing of paper, wood, ceramics, glass, pharmaceuticals and electronic products. Uncontrolled humidity levels affect the quality, performance and integrity of many of these materials, product safety and consistency, as well as transport costs and market value. Effective management of the humidity can dramatically improve both operating costs and product quality.

Application examples:
Electronics Industry:
Electrical and electronic equipment are highly vulnerable to the effects of uncontrolled humidity and moisture condensation. Moisture corrodes components and soldered connections, and can cause a short circuit, flash-over and current leakage. This translates into equipment malfunctions, production stoppages and constant maintenance. The use of FRAL dehumidifiers often translates into greater reliability and a substantial decrease in support and maintenance costs.

Plastics processing industry:
Every substance has some affinity for moisture. Even plastic resin collects from six to ten per cent of its dry weight in water vapour. In many cases, this is not a problem. In others, moisture can affect critical dimensions, like thermal expansion by making the product unusable or in any case lower quality. FRAL dehumidifiers provide optimal conditions for processing and storing plastics.

Pharmaceutical Industry:
Pharmaceutical products are among the most sensitive to variations in humidity and temperature. Powders, tablets, capsules and liquids can change their composition and quality due to a small variation in relative humidity. FRAL dehumidifiers provide optimal conditions for processing and storing pharmaceutical products and to protect equipment during their use. Some processes require desiccating or drying materials, for example tanneries, material washing, wood-processing. In these cases, the dehumidifier will be sized according to the water it will be required to condense over a given period of time. This process is significantly more efficient than high-temperature drying systems allowing potential energy savings up to 60%. FRAL dehumidifiers can be installed directly in laboratories or technical rooms. The relative ambient humidity value is controlled with a dehumidistat which allows the automatic operation of the dehumidifier. High efficiency FRAL dehumidifiers can even reach relative air humidity values of 15% and with advanced control systems, the margin of fluctuation can be reduced to +-1%. In processes where it is necessary to control temperature, industrial FRAL TCR models are available for managing humidity and temperature, or portable FRAL Air Conditioners are available just for cooling. With the experience gained over the years, and a skilled and flexible technical office, FRAL can provide solutions tailored to customer requirements.
