Hygienic line heat exchangers - Innovating hygienic performance 

Minimized fouling, superior cleanability, and simplified maintenance. All come together in Alfa Laval Hygienic line—a complete range of premium heat exchangers with unparalleled hygienic performance. 

A secure path to heating and cooling

Food safety standards are on the rise worldwide. With the new Hygienic line, Alfa Laval answers the call for a complete range of heat exchangers optimized for hygienic processing.

SmoothPort – Optimization is in the details

If you are looking for optimized heat exchanger hygiene, you should pay extra attention to the plate port. SmoothPort is one key to the unparalleled hygienic performance of the new Alfa Laval Hygienic line range of heat exchangers.

Thin plates - the evolution of efficiency

Thinner plates are more thermally efficient. Are they also less durable? Not when you rely on 100+ years of Alfa Laval innovation.

Improving cleanability and service

After many years of supporting food and beverage manufacturers, Palle Melchart understands the importance of cleanability and easy service in hygienic heating and cooling.

How Alfa Laval Hygienic line plate heat exchangers work

The space between the plates forms channels. The ports at the top and bottom of the plate enable two different media to flow through alternate channels. The hot media flowing in one channel transfers heat through the thin plates to the cold media in the other channel. Counter-current flow makes it possible to achieve the highest heat transfer efficiency. 

Several hygienic heat exchangers are combined in the same frame using connection plates for certain process steps, such as pasteurization. Using several connection plates enables the creation of additional sections. If a redesign is required, changing the inlet and outlet of these connection plates is easy.
