SV Mk.II (EN 1539) chamber dryer in which flammable substances are released up to 300 °C

Chamber dryers with EN 1539 standard safety equipment

Chamber dryers SV Mk.II (EN 1539) with safety equipment according to industrial standard EN 1539 are suitable for a wide range of production processes (drying, curing, preheating, vulcanization, etc.) during which flammable substances are released (e.g. volatile organic compounds VOC ). These can exist as gases, vapors, liquids, solids or their mixtures and can enter into an exothermic reaction with air when ignited. Typical applications are the drying of molding varnishes, surface coatings and impregnation resins.

The safety concept of the operation is based on the prevention of the formation of explosive mixtures by means of continuous ventilation in the entire working area of the dryer. The standard design of the dryers corresponds to the requirements of the EN 1539 standard for Dryer type A, and for operating area No. 1. The calculated values of the maximum permissible amount of flammable substance (see Technical parameters) were determined for the specified exhaust value and further for the following general parameters of flammable substances:

Flash point Δ LEL=20%/100K
Lower explosive limit LEL20=40 g/m³
100% content of releasable flammable substances from the paints
Zero losses through pre-drying

The values of the maximum permissible amount of the content of releasable flammable substances are calculated in relation to the worst case scenario, i.e. rapid evaporation of the paint over the largest possible surface. At lower drying rates or other types of flammable material being released, larger volumes can be processed per batch. If we know the specific values and parameters of the processed substances and the drying process, we are able to design and optimize individual atypical parameters of the dryer.

SV Mk.II dryers (EN 1539) are characterized by the very precise distribution of temperatures in the working chamber. A wide range of custom modifications, extensive accessories, very short delivery period and quick supply of spare parts are indisputable benefits.
