SpiroExpand MultiControl Modular (EMCM)
The SpiroExpand MultiControl Modular is an expansion and pressure maintenance unit in modular design for combination with pressureless EC expansion vessels (safety valve 0.5 bar) and a usable upper pressure of up to 16 bar.
The three MultiControl Modular systems and the standard upward extended working pressure range enables a wide range of applications:
- Solo: Single pump system, pump and overflow valve designed for 100% of the expansion volume.
- Duo: Double pumping system, pumps convey in parallel, allowing a greater expansion volume flow to be achieved. The overflow valve is designed for this volume flow.
- Maxi: double pump system, the pumps and the overflow valve are designed for 100% of the expansion volume. The 2nd pump is delivered as fail-safe.
The Duo and Maxi systems also have the option of two overflow valves (Twin), which are designed for 100% of the expansion volume.
SpiroExpand MultiControl modular systems are available with a usable upper workload pressure of up to 16 bar.
For example: the EMCM-D7-6.6-twin is a MultiControl Modular with DUO dual pump system. The maximum upper working pressure is 6.6 bar and the system is equipped with a double valve system (double).
Advantages of the SpiroExpand MultiControl Modular
- Already in the basic configuration, four potential-free signal contacts (fault, warning, replenishment active, device function activated) are available!
- The self-supporting construction and the casing ensure the lowest possible sound transmission.
- The standard upward extended working pressure range opens up an even wider range of applications!
- The connections for integration into the system (extension line, supplement) are located on both sides of the device.
Design of heating and cooling installations
SpiroExpand MultiControl modular units are designed to capture the volume of expansion and maintain a constant pressure in closed hot water heating, air conditioning and refrigeration systems in accordance with DIN EN 12828.

Touchscreen software update
Software updates should only be performed by our factory customer service or by trained service partners who are familiar with the devices and are aware of potential hazards and risks caused by software updates. In the event of non-conformity and direct or consequential damage, any warranty or warranty claim is excluded.
Note: During the implementation of the software update, the operation of the device is not guaranteed!
* Optimal degassing with a vacuum degasser or microbubble deaerator
Taking into account the VDI4708 and VDI2035 guidelines, Spirotech recommends the use of a separate microbubble deaerator or vacuum degasser to ensure optimal degassing of heating and cooling systems.
