Year Founded:

GIG Karasek provides systems and equipment, for the thermal separation of different mixtures, for among others, the pharmaceutical, polymer, petrochemical, oleochemical, finechemical, pulp & starch and food industries as well as for the environmental/recycling industries.

Therefore is GIG Karasek a leader in evaporation technologies, a major player when it comes to Thin Film and Short Path technology (Wiped Film evaporation technology) and a specialist in processing high-quality special materials. Anyone in need of tailor-made, precisely planned plant and equipment – for example, for the production of medication or vitamins, for the recovery of biological or chemical substances or for the purification of waste water from problematic industries – can’t fail to notice the customised product range that GIG Karasek has to offer. “Use no more energy than is absolutely necessary,” is a challenging goal shared by many of our customers. Instead of over-engineered design solutions, we offer intelligent concepts that not only save energy, but also lower costs.

The advantage of GIG Karasek is that you only need one partner for the implementation of your projects starting with lab and pilot plant tests, continuing with basic engineering, production and installation, and right up to the initial start-up and after-sales service.

Since GIG Karasek was founded in 1933, it has developed continuously and dynamically from a simple metal processing workshop into an internationally respected plant constructor with over 140 employees.

Even in the early years it was never too time-consuming for the company’s founder Franz Karasek to develop new products for his clients and to find new methods in production to achieve better quality and increasingly high-value technologies. Norbert Karasek changed the focus of production towards the paper and pharmaceutical industry and the processing of stainless steels. Now in the third generation, the points are already being set in the right direction with a great deal of subtlety. With the incorporation of Grill & Grossmann (GIG) site in Attnang-Puchheim in 1996 and expansion of the Graz office in 1998, GIG Karasek has matured to its present size with its impressive range of services. The next generation although still young is already showing huge enthusiasm for the company.

Joy in the enterprise duty and reinvesting the yields guarantee a growth also in the future.

Reliable solutions for solids loading currents to free-flowing products 
In the field ofdrying GIG Karasek provides a wide range of conventional drying technologies. Where other plants come to their limits when it is about heat sensitive products, the successful thin-film-evaporation-principle ensures gentle processes.  Based on their wealth of experience and knowledge from the separation technology, our experts implement powerful vertical and horizontal thin film dryers, convincing both economically and process engineering. For individual results, tailored to the market and so not available, our technical center provides the ideal R & D environment in order to cover in-depth tests etc.

The thin film dryer is a special design of the thin-film evaporator, which are used in chemical, pharmaceutical and other fields. There are 2 types, the vertical and horizontal dryer.

The product is distributed evenly in a thin layer by means of the rotor on the heating surface.  Through special wiper structures the thin film dryers allows to dry liquids up to the powder form. The aggregates (vertical / horizontal) can be used both, individually and combined (pre-drying in vertical, drying in the horizontal evaporator).

The GIG Karasek vertical and horizontal thin film dryer allow continuous operation with simultaneous discharge of solids.

Wide range of applications
The thin film dryer is mainly used in the chemical, pharmaceutical and in the food industry. Some typical examples of products would be: 
Chemical products (Precursor and intermediates), Sludge (Muncipal sludge, industrial sludge, process sludge), suspensions, pastes, Moisture solids, Saline Solutions, Products of fatty acid industry
