Alfa Laval Filters (ALF) are automatically cleaned fine and coarse filters primarily used to protect heat exchangers from contamination in a variety of applications.

Increased efficiency through protection against contaminants

Contaminants can cause serious undesirable effects, reduce heat transfer efficiency and limit the water flow rate through the heat exchanger. Such effects occur due to biofouling and the increase in surface contamination caused by the reduction in flow rate.

Alfa Laval filters are an effective and cost-effective solution to these problems, guaranteeing a reliable supply of cooling water. The system automatically carries out self-cleaning by reverse flow at regular intervals without interrupting the filtration or cooling process. This technology guarantees that there is no cause for concern for the operators of process equipment that is downstream of the ALF in the production chain.

Reduced energy costs

In addition, ALF has a high filtering capacity and low pressure loss, which reduces energy costs. Reduced pressure loss across the ALF heat exchanger and filter reduces the overall cost of a highly efficient cooling system. Few moving parts reduce maintenance costs.
