VapoChill cooling tower Refreshingly efficient

Kühlturm, Kühlung von Prozesswasser beim Pasteur

The energy required for cooling plays an important role in the beverage industry. Rapid, reliable cooling is critical to a variety of processes. Whether it’s the brewing of beer, bottling of juices, treatment of products in a tunnel pasteurizer, or flash pasteurization – efficient cooling makes it possible to quickly continue with the product’s further processing and also ensures high quality and impeccable flavor. With the specially designed VapoChill cooling tower, Krones has demonstrated a knack for cooling and for meeting the critical needs of the market.

VapoChill is built on a modular principle. Depending on the configuration, the individual models can later be easily expanded and/or combined. The design is based on Krones’ tunnel pasteurizers, which have performed successfully on the market for ten years now. The housing of the VapoChill is made completely of high-quality stainless steel, which means that the system is built to last. It is also available in the more chemically resistant V4A or AISI 316L stainless steel, on request. The tower packings, which are made of polypropylene, can optionally be treated with a biocide.

A significant advantage of the Krones VapoChill is its exceptionally clean design, which includes sloped surfaces that allow water to run off, the elimination of dead ends in the pipework, and a low volume of water inside the cooling tower. As a result, thorough cleaning can be accomplished with minimal personnel effort and time.

The cooling tower also offers excellent accessibility thanks to removable sidewalls and tower packings. Double detachable sieves make it possible to examine and clean parts of the system while it is in operation. Krones also offers dosing stations for water treatment chemicals as an optional extra. The chemicals themselves are sold by KIC Krones.

A new standard for more efficient cooling

VapoChill sets new standards for efficient cooling of process water. Compared with conventional cooling towers, it reduces process water consumption considerably. Infinitely adjustable control of the fan’s speed based on the desired cooling temperature avoids unnecessary cooling. The resulting reduction in motor power can also lower energy consumption by as much as 85 percent when the tower is operating at capacity. The EC fan features a brushless motor, which enables maintenance-free fan operation and maximum drive efficiency.

The VapoChill proves consistently flexible in ongoing operation and can be used in any application where process water needs to be cooled. It does not have to be combined with another Krones system to do so. The VapoChill can also be used for applications outside the beverage industry that work with cooling water. If the system uses a different coolant, a heat exchanger may need to be installed as an intermediary. And Krones has a preconfigured solution in its portfolio for just that purpose. If the cooling tower is connected to other Krones machines, all of the relevant control systems can be networked, which simplifies operation to a single, integrated system.

Thus, the VapoChill cooling tower from the House of Krones offers not only a clever solution for cooling process water, combined with enormous savings in energy and ongoing costs. Krones also stands behind the entire underlying system, with its scope of supply including a tailored control system as well.
