Differential pressure, flow and temperature controllers

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.

Product range

  • Differential pressure controllers- Danfoss
    Differential pressure controllers

    Differential pressure controllers keep a constant and lower differential pressure across a motorized control valve or a total system/substation. This eliminates pressure variations and improves temperature control quality.

  • Differential Pressure Controllers & Flow Controllers Limiters- Danfoss
    Differential pressure controllers & flow controllers / limiters

    With Differential Pressure Controllers & Flow Controllers / Limiters you can control the flow available for each consumer as well as the differential pressure control at the substation. This allows efficient network balancing.

  • Pressure independent control valves- Danfoss
    Pressure independent control valves

    Pressure independent control valves ensure efficient control, delivered in a simple way.

  • Pressure relief controllers- Danfoss
    Pressure relief controllers

    Pressure and differential pressure relief controllers can protect variable flow pumps from overload in the event that flow falls below minimum pump capacity. They relief pump/application and forward heat power to other connections.

  • Safety pressure controllers- Danfoss
    Safety pressure controllers

    Safety Pressure Controllers through automatic opening of the valve prevents exceeding pressure before the valve and behind the valve.
