Models for 2 and 3 heating circuitsOZB-A-35-х and OZB-A-50-х

For heating systems that do not require hydraulic separation of the boiler circuit and consumer circuits. For example, systems with a buffer tank (e.g., heat pump + BT, solid fuel boiler + BT).

OZB-А-35Hydraulic blocks with Dn20 connection

Maximum heat carrier flow rate – 2.2 m³/hour

OZB-А-50Hydraulic blocks with Dn25 connection

Maximum heat carrier flow rate – 2.9 m³/hour
