TUNNEL THERMAL TECHNOLOGY - Suitable thermal process of already filled product can be crucial from several aspects such as product’s quality, its lasting shelf life and outside appearance. All this we can provide with our most standard and referential product group – tunnel technology.

This modern, up to date technology can be used for three different kinds of thermal processes after filling:

•Pasteurization after cold fill of product.

•Cooling after hot fill of product.

•Warming after cold fill (when already flash pasteurization was applied before filling).


Sophisticated technology for gradual heating of already filled product from inlet temperature up till pasteurizing temperature, holding on pasteurizing temperature for necessary time and gradual cooling to outlet temperature.

The platform of pasteurization process is a precise temperature regulation that enables exact thermal process which is essential for quality of your product and its required shelf life. These values are achieved through properly reached number of pasteurizing units (PU’s). Special feature of our pasteurizers is active control of pasteurizing units also in case of production stop-down. With our own developed system and software we can secure safety and constant thermal process without any frights of possible “under” or “over” pasteurization.

Main features of our systems are:

•Active monitoring and control of PU which enables that the set value of pasteurizing units is always within agreed tolerances (also in case of stoppages on filling line).

•Efficient heat exchange provided between heating and cooling zones enables very rational process in terms of heat energy required for normal pasteurization process.

•Heating is preformed indirectly by means of heat exchangers.


When temperature differences between product and production room are significant, heating of product inside container is necessary to avoid subsequent condensation of container surface. Condensation is a problem that can occur already in production room or later in a warehouse. Wet containers can cause following issues: problems of label application, of destroyed packages or printing.


Cooling process is applied at hot fill production process after products are filled and need to be cooled down relatively quickly to ambient temperature of production room or warehouse. Quick cooling is recommended when we have to prevent products retention on high temperature for too long in order to avoid certain damage of products’ colour, taste and other organoleptic properties.

Function: Precise product cooling down to the required temperature prompt after the container entrance into the tunnel. Heat exchange is provided by water coming from an outside cooling source (cooling tower, cooling aggregate etc.).


Because food and beverage industry does not tolerate anything less than perfect intactness we have to assure for some more delicate products after hot fill to stay under pasteurising temperature a little longer.

This solution is usually applicable where transport distance from the filler to the cooling tunnel is door-to-door or very short so that the product does not stay on the required pasteurising temperature long enough.


•Modular structure that enables easy loading, transport and assembly.

•Complete stainless steel construction with no carbon steel parts.

•Innovative design solutions.

•Rational energy consumption.

•Considerable “world famous components” that assure long life period of machine and easy maintenance.

•Modern and accessible software for simple use of device, adding of new products or parameters modification of the pre-set programs.

•Complete adaptability to concrete technological requests.
