and freezing

Examples from our portfolio

Shock freezer.

Our shock freezer enables the shock freezing of food and dishes within a few minutes and is indispensable to the catering industry. In addition to the required temperature management, it offers optional areas of product customisation.

  • Formation of microcrystals instead of macrocrystals avoids damage to the cell structure, for better food preservation
  • Temperature range: -40°C to +60°C
  • Customised touch display
  • High-pressure safety shut-off via pressostat
  • Fully automated programmes, e.g. blast freezing to minus 18 degrees core temperature or for chilling drinks

Development and series production of OEM devices in the field of extraction systems for hobs and generation of vacuum
Downdraft extraction systems

Through the Appliances and Ventilation & Surfaces divisions, we develop and produce various downdraft systems for a wide range of cooktop variants, including electric cooktops and cooktops with induction or radiant heating technology.
For this purpose, we use our expertise in appliance and component manufacturing as well as in the development and optimisation of blower systems.

The advantages:

  • Increase in ventilation efficiency
  • Reduction of noise emissions
  • Ensuring a low installation depth
  • Wide range of design options


Cooker hood systems

We develop and manufacture complete cooker hoods and extractor hoods or individual components for both the gastronomy and household appliance industries. We customise the design and functionality of the hoods, and develop the integrated fan system with optimised performance and noise levels.

Customisation options:

  • Interface (position and design of the icons, colour of the LEDs).
  • Various lighting options for the hob below
  • Front designs in all materials – aluminium, stainless steel, glass


Vacuum drawers

Our vacuum drawer enables the gentle preparation and natural preservation of food.
The concept was developed by Gronbach itself and is produced in series at our own plant.

The biggest advantages of the drawer, compared to other vacuuming devices, are its compact design and the pressure control. In contrast to most free-standing devices, our vacuum drawer vacuums not only the bag itself, but rather the whole chamber – so there is no pressure difference acting on the food during vacuum packing.


Development and series production OEM devices in the field of fluid systems, fluids
Built-in fully-automatic coffee machine

Gronbach has exploited its expertise to develop and assemble high-end fully-automatic built-in coffee machines and espresso machines for gastronomy and for private use. We supply a wide range of design-oriented functional components and assemblies (drip plates, front panels, frames, operating elements, racks) as well as complete high-end built-in fully-automatic coffee machines and espresso machines for the catering trade and offices.

Development OEM equipment in the field of vertical farming, vertical gardening
Vertical Farming

Our group participated in the development of a household appliance for the domestic cultivation of salads, herbs and other plants, including the development of the metal frame for optimised industrial production.
In the field of vertical farming, we are active both as a complete equipment manufacturer and as a developer and producer of assemblies and individual components.


Manufacturer cooktops and downdraft exhaust systems for the home appliance industry.

On behalf of our customers, we develop and manufacture functional and design-oriented cooktops for many types of heating, including electric cooktops, cooktops with induction or radiant heating technology, and cooktops with downdraft extractors. We work together with renowned suppliers of glasses and electronics for this purpose.


Warming drawers

Warming drawers are ideal for preheating dishes or keeping food warm. For a uniform look, they can be combined with other household appliances, e.g. ovens, steam cookers or built-in fully automatic coffee machines in the kitchen front, but they can also be adapted to customer-specific specifications.
Our warming drawers were developed in-house and are mass-produced on an OEM basis for our brand customers and are constantly being developed to meet new demands in the household appliance sector.

Racks and fronts

The racks and fronts are designed, mass-produced and finally assembled according to the customer specifications of well-known appliance manufacturers. We either manufacture the necessary assembly components ourselves or obtain them from our affiliated supply partners. They are characterised by a high degree of precision and robustness.
Depending on the customer’s order, we realise a wide variety of decors, e.g. made of glass and/or aluminium, and also integrate user-oriented operating elements.


Extension rails

Partial-and full-extension rails for ovens and range cookers represent a central product group in our portfolio, enabling a particularly stable and low-noise gliding movement for the end user. Outside the household appliance industry, our drawer rails are adaptable for alternative fields of application, e.g. for the furniture industry.


Hinge solutions

We manufacture mechanical and electromechanical flap door hinges for installation on the door or appliance side, primarily for the household appliance industry. We adapt these according to the installation situation and the requirements of our customers for a perfect fit. Through our platform, we are able to adapt our solutions not only to new household appliance models, but also to alternative application areas and industries.


appliance development.

In accordance with the individual requirements of our customers, we develop and manufacture products in series as ODM and OEM and, if desired, take over the packaging design and logistics. We have many years of experience in development and series production for the household appliance and catering industries, and are active for the medical technology and entertainment industries, among others.
