District heating – heat exchanger for heating

Introduction

Heat exchanger for heating graphic

Typical for applications are: slow changes in heating demand; high operating pressures and temperatures; safe and reliable operation even under extreme operating conditions is essential; fail-safe function is required; 2-port flanged or threaded valves; 3-position control.

The proposed combinations vary in: control accuracy; plant operating conditions, amount of flow volume.

High performance, high control quality solution
