Kelvion launches heat exchange solution for the dairy industry

The new NL100M plate

BOCHUM, Germany, 20 May 2020: Kelvion said its new NL100M is ideal for a wide range of dairy products. A challenge in those applications is that the product needs very careful handling, with minimum stress to achieve the desired smooth texture and viscosity, Kelvion said by way of highlighting the NL100M’s capability.

The answer to the challenge, the company elaborated, is a heat exchange solution that combines low velocity with low pressure. With conventional plates, low velocity reduces the performance, leading to a build-up of deposits on the surface, but the plate heat exchanger with NL100M plates, and with the OptiWave plate design, offers an outstanding inter­action of the plate profile and corrugation depth, the company claimed. It ensures high heat transfer rates by means of uniform distribution of the product over the entire width of the plate, the company said. The large gap of 4.15mm keeps the original product’s viscosity at a high level, the company said, adding that furthermore, the NL100M is suitable for oil and steam and glycol applications, where low pressure drop is the limiting factor.

For dairy products and other high viscose media

The new NL100M plate, big brother to the NL80M plate, is available in titanium, as well, for ultra-purity and cleanliness, the company said. And, it’s already making its mark, with large orders coming in from contractors in the food and beverage industries, the company added.

The NL100M plate offers the ideal compromise between flexibility and efficiency, the company claimed, adding that it is suitable for operating pressures of 16 bar, provides connections with a nominal diam­eter of 100mm and has a heat exchange surface area of 0.47m² per plate. With a gap width of approximately 4.15mm, the company said, it provides enough space to allow media containing particles to pass through and also provides improved heat transfer, compared to plates with even bigger gap width or wide gap patterns.

The advantages of reducing the gap width to approximately 4.15mm are a significant improvement in heat transfer in the double digit percentage range and lower energy consumption, the company said. Customers benefit from a good heat transfer rate, less build-up of fouling and extended production times, the company added.

The product’s PosLoc assembly system and EcoLoc gasket system ensure easy assembly of the heat exchanger during installation and maintenance, the company said. The PosLoc design makes sure that the plates of gasketed plate heat exchangers align automatically during assembly and seal tight, the company said. The EcoLoc gaskets can be at­tached easily without special tools or adhesives, the company said. When the device is closed, the company said, the correct fit is established automatically, which results in reliable gaskets that can be replaced, if necessary, quickly and easily.
