Heat exchanger for beer, dairy and other high viscous media
Kelvion has released the new NL 100M plate, the big brother to the NL80M plate, offering high service life and high efficiency.
Available in Titanium for ultra-purity and cleanliness, the plate is already making its mark, with large orders coming in from contractors in the food and beverage industries, according to the company.
The NL100M plate now offers the ideal compromise between flexibility and efficiency. 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 approx. 4.15mm, it provides enough space to allow strongly-hopped media 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 approx. 4.15mm are a significant improvement in heat transfer in the double digit percentage range and lower energy consumption. Customers benefit from a good heat transfer rate, less build-up of fouling and extended production times.
As well as brewing the NL100M is ideal for a wide range of dairy products. The challenge in those applications is that the product needs very careful handling, with minimum stress to achieve the desired smooth texture and viscosity.
The answer 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, with the OptiWave plate design, offers interaction of the plate profile and corrugation depth. It ensures high heat transfer rates by means of uniform distribution of the product over the entire width of the plate. The large gap of 4.15mm keeps the original product’s viscosity at a high level.
Furthermore the NL100M is suitable for oil and steam and glycol applications where low pressure drop is the limiting factor.
