Optimal hydronic balance and perfect temperature control are the key to maximizing the efficiency of heating or cooling networks. As a world leader in heating control technology, we offer a comprehensive range of products and integrated solutions for even the most challenging district energy conditions. Danfoss control solutions improve the efficiency of district energy networks and allow end-users to enjoy an ideal indoor climate while maximizing energy efficiency.

Differential pressure controllers automatically ensure dynamic hydronic balancing in the district energy network

Water flows through a supply network according to the principle of least resistance. If there is no hydraulic balance, the consumers nearest to the power supply enjoy a better service than more remotely located consumers.

Differential pressure controls can be used to reduce available differential pressure in a specific area of a network (area control), before each building subscriber station or at each control valve. By limiting differential pressure to the required value, this automatically and dynamically balances the network, ensuring that all consumers receive the specified flow.

The system will remain in balance and will not require rebalancing, even when the network is extended to new areas.

This also applies in the event that the location of the energy source changes, or during significant variations in user consumption. This not only contributes to energy efficiency but also improves end-user comfort.

Differential pressure controllers eliminate pressure variations and provide optimum operating conditions

In variable flow systems, large variations arise in the available differential pressure. Because they are sized for the lowest available differential pressure, this means that the control valves are forced to work with a very small degree of valve opening and at many times larger differential pressure.

At these high pressures, the valves become too large and temperature control inaccurate and unstable. This causes unnecessary equipment wear and higher return temperatures, as well as affecting the other valves in the system.

The differential pressure control is thus the key to eliminating pressure variations and providing control valves and house stations with lower and stable differential pressure. Good working conditions for control valves increase the quality and precision of temperature control, even for low flow requirements. The connected system is protected against pressure surges, fluctuations, cavitation and noise.
