Industrial refrigeration: Finder solutions

Starting from the so-called ‘conquest of cold’ – the name by which the invention of refrigerators in the 20th century is known – refrigeration systems have been subject to non-stop evolution and innovation, and have expanded into different types of products in various sectors, such as food, medical, chemical/pharmaceutical and air conditioning.

The most popular applications in the refrigeration sector include:

  • cold rooms;
  • refrigerated counters and cabinets;
  • refrigerators;
  • blast chillers.

In compliance with the standards in place concerning refrigeration, Finder offers a wide range of products for:

  • the control of compressors for refrigeration loop generation to manage compressor programming and overall operation;
  • condensate level monitoring for refrigerated counters and cabinets.

With a compact footprint, the capability to manage high inrush currents, high sensitivity and control accuracy, Finder components are suitable for a wide range of refrigeration applications, and they boast a high number of agency approvals and certifications.
