Topcontrol modular TCM

The elko-mat eder topcontrol devices are the consequent further development of the well established multicontrol modular MCM devices and the elko-mat patent, that is proved and tested for decades and thousandfold.

Topcontrol devices are designed for lossless acceptance of the expansion volume and for keeping the pressure constant in closed warm water heating-, climate- and cooling-devices, according to EN12828.

Topcontol modular TCM is an expansion- and pressure maintenance unit in modular design for combination with the pressureless EG expansion vessels (0,5 bar safety valve).

Additional to the standard signal contacts „error“, „warning“, „make-up in operation“ and „device operation enabled“ the basic configuration of the topcontrol device includes two analog standard signals (4-20mA) „current vessel level [%]“ and „current system pressure[bar]“ for integration to an on site process control.

By the self supporting construction and the housing a minimal sound transmission is ensured.

Using electronic speed-controlled pressure maintaining pumps and electric overflow valves a huge scope of application of the single device types is possible. Of couse, within the top control device the four systems „solo“, „duo“, „maxi“ and „twin“ are available, depending on the necessary reliability.


The connections for integrating into the system (expansion pipe, make-up) are foreseen at both sides of the device.

Using the successful exeriences of existing elko-mat EDER systems – based on the multicontrol devices – many detail improvements were implemented to the topcontrol facility series.

Following combinations of the topcontrol modular TCM are available:

Systems solo, duo, maxi and twin
useable upper working pressure up to 23.5 bar.

Additionally to the basic configuration following original accessories for the topcontol modular TCM are available:

Elko-mat EDER EG expansion vessels and EGZ additional expansion vessels

Multicontrol MCF-1 (1/2“) and MCF-3 (3/4“) make up module for amount controlled make-up

Mulitcontrol MAE-1 low pressure degassing module

Extension modules for analog and binary remote monitoring and binary remote monitoring with remote quitting for extended signal exchange with the process control

SMS module for mobile and alltime smooth remote monitoring
