Pumping and inertial storage tank kit

NECS 0202T - 0612T
The system capacity can be increased by installing an accumulator between the refrigeration unit and a user. Thanks to the increased thermal inertia, this ensures a number of advantages: – Longer life of the refrigeration machines due to longer working-time of the compressor between two starts. – Reduced water temperature swings, which results in greater stability of final adjustment. The SPF units consist of a package containing all the necessary components for outfitting a refrigeration unit; they are optimised to satisfy a large number of requirements: Low or high prevalence units. With one or two 2 and 4-pole pumps. With housing box, suitable for installation in nontechnical rooms and locations exposed to the weather. Without housing box, suitable for indoor installation and limited access locations (available capacities 300 – 500 litres).
