Slider_icecube_PantherLiebherr refrigerators with an IceMaker automatically keep you topped up with ice cubes so you can enjoy refreshing drinks with ice whenever you want. But what kind of technology enables you to enjoy your drinks ‘on the rocks’?

Surely, you can imagine yourself here? It’s a hot summer day and you’re sitting in the garden, or on your terrace, with a cool glass of juice or cordial and you take things to the next level by adding a little something extra… a few ice cubes! There’s that moment when the ice cubes hit your drink… crackling softly, before they slowly dissolve. Total bliss! This is just what you needed; it’s just what summer’s all about – and drinks absolutely must have ice cubes! But how does Liebherr create ice cubes? What technology lies behind the process and how come the ice cubes are so perfect?


Ice cube geometry

In the first instance, of course, water must change its physical state from a liquid to a solid to create ice or ice cubes. In Liebherr appliances, the finished ice cubes are made from about 9 ml water, which corresponds to a ‘weight’ of about 9 grams each.  Before the water is turned to ice it must first be ‘fed’ into the appliance, and this is done in one of two ways: either the appliance has a plumbed-in connection or it has a water tank. We’ll consider that a bit more later on, but first let’s look at how the ice cubes are produced. The plastic ice cube tray is automatically filled with water by the electronic system that operates within the IceMaker and IceCenter appliances. Depending on the type of water supply, either a pump (water tank) or a solenoid valve (plumbed-in connection) is activated for a specific amount of time for filling.

A sensor under the ice cube tray detects when the water is sufficiently frozen and then starts the process of automatically ejecting the ice cubes. To do this, the ice cube tray is rotated and, on reaching a certain ‘twist angle’, the back section of the tray stops moving while the front end continues to twist by a further 20° causing the cubes to be released – this is similar to the manual process of twisting an ice tray so that the ice cubes pop out. And hence we get the name: TwistTray. Unlike some other manufacturers’ models, the ice cubes are not thawed slightly to facilitate their release and so Liebherr ice cubes never clump together in the storage tray – contributing to their irresistibly appealing shape.

Appliance with IceMaker – plumbed-in connection or water tank?


Available with water tank or plumbed-in connection: Liebherr appliances with an IceMaker

As already mentioned, when you choose a Liebherr refrigerator with an IceMaker you can either opt for one with a plumbed-in connection or one with a water tank. The main difference is that you have to refill the water from time to time with the latter, but the 1.2 litre water tank provides an innovative solution if water quality is low or if there is no water feed. It can easily be removed for filling. The plumbed-in IceMaker will provide a continuous supply of high-quality ice cubes whatever the occasion. Depending on the model, the IceMaker produces up to 0.8 kg/24 h in built-in, 60 cm wide appliances and 1.0 kg/24 h in 75 cm wide appliances. All models featuring a plumbed-in connection have an ice cube container that holds 1.5 kilograms. Plumbed-in connection appliances are fitted as standard with a high-quality ¾”, 1.50 m connection hose, and if required, a 3.0 m flexible reinforced hose can be ordered from the Liebherr customer service team.

The following Liebherr appliances have an IceMaker with a plumbed-in connection:

  • CBNPes 5167
  • CBNPes 3967
  • SBSes 7165
  • SBSes 7353
  • CBNes 6256
  • SBS 70I4
  • ICBN 3366
  • ECBN 5066

In the following appliances, the water is supplied from a water tank:

  • CBNPes 3976
  • ICN 3366
  • CNesf 5123

The Liebherr IceCenter offers optimum versatility for serving cool drinks, delivering ice cubes, crushed ice and chilled water. All of these can be obtained by pressing the touch-sensitive paddles, which are illuminated by an LED light during use (the light can be switched off if not required). An integrated water filter ensures optimum water quality. (Features available on SBSes 8283)

Incidentally, Liebherr has been manufacturing automated ice cube systems since 2003. Appliances with an IceMaker produce almost conical ice cubes for the simple reason that this shaped ‘cube’ is easier to release from the tray once frozen. Ten ice cubes or ‘ice cones’ are made at a time and, if needs be, new ice cubes can be made every two hours thanks to the speedy automated ‘production process’. In addition, the rate of ice cube production can be increased by almost 50% by pressing the SuperFrost button.

And before I forget… not all ice cubes are made of ice…! There is nothing that can’t be found in today’s digital world… including ‘digital ice cubes’ – which, naturally, come from Liebherr! You can download these to your iPhone whenever, and wherever, you like. Free of charge, of course!
