Willmes Merlin PLUS+ horizontal pneumatic presses -

Willmes' Merlin PLUS+ horizontal pneumatic wine presses feature a double-sided membrane for double the area of pressure application, and vertical electropolished stainless steel juice channels for excellent press results. The Merlin PLUS+ is equipped with a range of pressing programs which Willmes have developed and perfected over the years, which are favoured by leading oenologists and experienced users around the globe.

Models are available from 1200 to 5100 litres capacity.

When compared with conventional pressing systems, the Merlin PLUS+ benefits include:

  • 50% lower pressure - the double membrane technology doubles the area of pressure application, thereby halving the pressure at the same force
  • Higher juice yield - the short juice paths through the vertical juice channels and double the area of pressure application allows yields up to 90% at pressures of less than 0.8 bar and results in an extremely high quality must
  • Shorter pressing time - with the Willmes Pressing Principle (see Features), pressing times are reduced by up to 30%
  • up to 40% less lees - gentle processing of grapes frequently leads in only 2% lees, so net juice yield and must quality are significantly increased
  • 25% more filling quantity - the optimum pre-juicing due to special design of the press tank and the vertical juice channels enables a considerably higher amount of filling material

The Willmes Pressing Principle:

  • 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 from all sides on the material to be pressed.

  • Vertical juice channels: The double-sided membrane presses the material to be pressed against the vertical electropolished 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. This makes 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; therefore, there are less lees and a higher yield of juice of premium quality.

Other features include:

  • Intelligent pressing programs, which are perfectly adapted to all grapes and types of grave harvest for optimum pressing results
  • Easy and intuitive operation via touch-screen
  • Large filling opening over the whole length of press tank to simplify and accelerate the filling/emptying process (filling hopper with lifting shoes optional)
  • Unique filling opening ensures optimum distribution of the material to be pressed, while dispensing with all rotations for enhancing distribution
  • The vertical juice channels can be be dismantled in a few simple steps for easy cleaning
  • Corner and edge-free press body for minimal dirt traps and reduction in cleaning times
  • Pneumatic control with reversible blower for an efficient and energy-saving pre-pressure and evacuation control (integrated compressor optional)
  • Round-shaped, sliding juice tray (must pump control optional)

Willmes invented the modern pneumatic press and continue to innovate and make top quality equipment with features not found on other presses.

Willmes presses are exceptionally well made and offer unique features that put them at the forefront of press design. Willmes, established in 1918, invented the modern pneumatic press in 1951 and remain market leaders. There are currently about twenty Willmes presses giving good service in UK vineyards. Willmes presses have vertical juice channels, which produce high quality juice at low pressures. This system also allows good pressing performance with small amounts of grapes.

Willmes presses from Vigo offer many advantages:

  • Robust construction
  • High yields of premium quality juice at low pressures
  • Ease of operation and maintenance
  • High retained value
  • Commissioning by Vigo engineers
  • 5 year warranty with annual service visits by Vigo engineers
