One assembly for two mixed circuits with return flow utilization and two-zone principle at the buffer storage tank   For highly efficient two-zone discharge of a buffer storage tank in a mixed low-temperature circuit (2nd mixing circuit) with highly efficient use of the return flow of a mixed high-temperature circuit (1st mixing circuit).   With this product it is possible to double to triple the usable buffer volume.

Capacity DN 25 light version: 1. mixing circuit: Kvs = 6,2 - V'max[100mbar] = 2m³/h - Q'max[20K] = 47kW 2nd mixing circuit: Kvs = 6.2 - V'max[100mbar] = 2m³/h - Q'max[10K] = 23kW   Capacity DN 25 heavy version: 1. mixing circuit: Kvs = 11,9 - V'max[100mbar] = 3,8m³/h - Q'max[20K] = 88kW 2nd mixing circuit: Kvs = 12,9 - V'max[100mbar] = 4,1m³/h - Q'max[10K] = 48kW   Capacity DN 32 version: 1. mixing circuit: Kvs = 11,9 - V'max[100mbar] = 3,8m³/h - Q'max[20K] = 88kw 2. mixing circuit: Kvs = 18,9 - V'max[100mbar] = 6m³/h - Q'max[10K] = 70kW
