CIM/CIU communication interfaces enable control of pumps and pump systems
Saving you time and money while delivering peace of mind, Grundfos CIM/CIU communication interfaces are the ideal solution for control of pumps and pump systems. The Communication Interface Module (CIM) and the Communication Interface Unit (CIU) enable data communication via open and interoperable networks.
This Grundfos fieldbus concept is easy to install and commission, and the CIM/CIU communication interfaces support a wide range of Grundfos products. All modules are based on standard functional profiles for easy integration into the network and easy understanding of data points, improving your ability to control pumps and pump systems.
Whatever your system challenges, there are several ways intelligent controls can help. In our controls application guide, you can learn everything there is to know about how to install and commission our solutions to fully optimise your HVAC system. Find out how to:
- Reduce energy consumption
- Increase system performance
- Reduce manual monitoring
Does a distributed pumping solution require hydraulic balancing?
No. Because we use small circulators as coil pumps to supply chilled water to each terminal unit (ie. Air handling unit), your entire building will be perfectly balanced at any load.
This also simplifies the design phase, as it is no longer necessary to determine the critical pressure point / index loop when doing the HVAC design. With distributed pumping, your whole system becomes decoupled and each pump is sized to deliver just the right flow.
How is the Capital investment compared to a conventional system with valves?
Because a Grundfos Distributed Pumping system is replacing the valves with coil pumps and reduces the kW size of primary pumps, the Capital Investment will either be the same as a conventional system or around 20% more expensive, depending on the choice of valves in the conventional design.
But the commissioning efforts needed for a distributed pumping solution, will be much less, since there is no need for hydraulic balancing or determination of Set Points (ei. Constant ...
How reliant is a distributed pumping system compared to a conventional system?
Canned-rotor type of circulates have been manufactured by Grundfos since 1959 and integrated speed drives was introduced in 1991, so the design is incredibly reliable and well tested. The current version of MAGNA3 was realeased in 2012 and more than 1 millions units have been sold worldwide for mixed applications.
The expected lifetime of a MAGNA3 is 10 years, but the pump can easily operate longer than this, and is more than able to match the reliance of any type of control valve....
