Double membrane technology
In contrast to a half-sided membrane, the double-sided membrane has a substantially larger (double) area of pressure application. In terms of physics, this means less pressure expenditure and less compression of the material to be pressed at the same force, which acts uniformly on the material to be pressed from all sides.

- Quick disassembly of vertical juice channels and corner-edge-free design minimize cleaning times
Vertical, flexible juice channels
The double-sided membrane presses the material to be pressed against the vertical juice discharge areas, which act like natural drains. Irrespective of the filling height, this always results in the same short juice paths, which allows the juice to drain more directly and quickly. If the membrane is relieved of pressure (vacuum released), the material to be pressed falls together.
The lateral pressure direction and the flexibility of the juice channels lead to continual self- cleaning of the mesh tissue. These things make the rotational effort for crumbling negligible and fewer pressing cycles are required. The mechanical load on the material to be pressed is kept to a minimum, thus resulting in a lower quantity of lees and a higher yield of premium-quality juice.

| Name | Description | Merlin | Sigma |
| Automatic valve in the cover | The additional automatic door valve allows a separate ventilation of the air in the pressing chamber. This prevents unwanted contact of the grapes with oxygen. read less | No | Yes |
| Central filling | Fast central filling of the press with minimal rotation required for gentle grape processing. read less | Yes | Yes |
| CIP – integrated cleaning system | The CIP cleaning system offers a comfortable and extremely fast solution for thorough cleaning of the press. The hardware and software components are coordinated so that the complete cleaning process is controlled automatically. read less | No | Yes |
| Cleaning program | Special cleaning program for fast and effective intermediate cleaning of the press. | Yes | Yes |
| Cooling system | For cooling or maintaining a defined mash temperature in the press. In addition to the isolation of the press drum, an active cooling within the container may be necessary. The principle of SIGMA presses offers therefore the ideal conditions: read less | No | Yes |
| Filling system via cover | The door filling system is used to automate and ensure the desired filling level when filling the press. read less | Yes | Yes |
| Chassis | With the mobility of the press, and with appropriate planning, important advantages in the production process can be achieved (in terms of time and quality). For example: driving the press from the place of filling (red wine tank) to the place of pressing or to the place of emptying (pomace disposal). read less | Yes | Yes |
| Emptying program | When emptying the press with the door completely open, the large amounts of pomace in the first rotations can lead to clogging of the pomace (for example: pomace screw). The convenient solution is the emptying program, which allows a continuous emptying of the press. read less | No | Yes |
| Filling with inflated membrane | The use of a flow meter ensures a multitude of advantages in process monitoring: – Volume flow measurement [litres / minute] – Display of the already drained amount of juice [litres] read less | Yes | Yes |
| Flow Measurement | The use of a flow meter ensures a multitude of advantages in process monitoring: – Volume flow measurement [litres / minute] – Display of the already drained amount of juice [litres] read less | Yes | Yes |
| Inert gas | The optional equipment “inert gas” allows operating the Sigma press in inert atmosphere to exclude or control unwanted oxidation processes. read less | No | Yes |
| Must-pump control unit | With the help of the juice pump control, overflow of the juice tray is prevented. Furthermore, the juice discharge from the press is stopped when the pump power is too low according to the set parameters. read less | Yes | Yes |
| Must separation controlled to the litre | Well-known from Champagne production: The litre-controlled must separation is interesting for anyone who wants to get more out of their wine without having to operate valves manually. There are good reasons for it: – You want to offer different qualities to maximize the profit – To specifically process the various fractions according to their individual nature read less | Yes | Yes |
| Must separation Cycle and pressure controlled | The must separation depending on cycle or pressure is interesting for anyone who wants to get more out of their wine without having manually operated valves. There are good reasons for it: – You want to offer different qualities to maximize the profit – To specifically process the various fractions according to their individual nature read less | Yes | Yes |
| Maceration program | The maceration program enables a standardized sequence with regard to rest times and rotation. Thus, a controlled maceration process is possible using the entire press capacity. read less | No | Yes |
| Manual control unit of the juice drain valve | In addition to the complete opening or closing of the juice drain valve on the press, a partial opening may also be advantageous: With the manually controlled juice drain, the juice valve can also be opened step by step: thus, an undesired shooting out of the free juice during the door filling or axial filling can be comfortably controlled. read less | No | Yes |
| Mobile hopper | The completely stainless steel hopper from Willmes is the comfortable and safe solution for the gentle filling of your press via the door opening by means of Euro boxes and slewing ring. read less | Yes | Yes |

| Program structure: UCE | The UCE program structure with a total of 12 memory locations is based on a maximum of 9 cycles, which in turn can be repeated a maximum of 9 times to allow the best possible adaptation to the grapes. In the foreground is a gentle juicing with low pressing pressure in the shortest possible time. The operator can not only create any program step, but also automatically control the program history and program end. read less | Yes | Yes |
| Program structure: VSQ | The automatic program VSQ is a universal pressing program. For individual handling of each program, individual cycles can be repeated as required, entire sequences of cycles can be skipped or repeated, and specific cycles can be targeted. The VSQ automatic program can freely program up to 99 cycles. Each cycle consists of a pressure stage to increase the pressure to set pressure (p n), a pressure hold time (d n) and a number of rotations (R n). These parameters are freely programmable. read less | Yes | Yes |
| Rocking program | Filling via the doors of the press with whole bunches leads to a pouring cone, which complicates a complete filling of the press. Therefore, in order to be able to completely fill the press, the filling must be interrupted several times. This procedure is very time consuming and not gentle on the grape material. read less | Yes | Yes |
| smart interface 4.0 | Via the local network connection, current and historical press data are transmitted to the PC via the smart interface. There, programs can be monitored, analysed, changed at will, and replayed to one of the panels of the panel for future pressings. Any malfunctions will also be forwarded via the in-house email server via push service to mobile devices such as mobile phones or tablets. read less | Yes | Yes |
