difference between stationary and portable machine

We are still preparing products.

But you can look at other categories.

Selecting the right KAMMAK rinsing machine is a key decision for the efficiency of every professional kitchen, yet we often encounter uncertainties regarding whether a stationary model needs to be installed or if a portable variant is sufficient. The difference between these two types is not only in their size, but primarily in the way they are connected to the plumbing and adapted to the specific operational requirements of your business.

Physical construction and placement

Stationary machines are designed as fixed units that are permanently mounted on the floor or into a specially designated work area and are directly connected to the water and sewer system. These machines have a more robust construction with a larger water volume and often feature an integrated pump that ensures stable pressure without dependence on an external source. In contrast, portable machines are designed to be mobile and easily transportable, making them ideal for smaller businesses or as a backup solution for seasonal needs.

This diagram visualizes the basic difference in infrastructure: while the stationary model requires permanent piping, the portable one relies on flexible hoses and manual drainage.

Water and sewer connection system

The difference in connection is the most technically significant point, as it affects not only installation, but also safety and maintenance speed. KAMMAK stationary machines require a fixed connection to cold water with sufficient pressure and direct drainage into the sewer system, which means the need for a plumber and compliance with wastewater regulations. This type of connection eliminates the risk of overflow and ensures maximum stability during intensive operation, as water flows directly into the system without intermediate steps.

Fixed piping ensures a constant flow without pressure loss.
Drainage into the sewer eliminates the need for manual water emptying.
Permanent connection allows integration with other appliances in the kitchen.
The risk of environmental contamination in case of accidental overflow is reduced.

On the other hand, portable machines operate on a "plug and play" principle, where it is sufficient to connect the inlet hose to a tap and the outlet hose to a bucket or sink. Although this is a very practical solution for restaurants with limited space that cannot modify the plumbing, it requires the operator to carefully monitor the water level in the drainage container and regularly empty it.

Performance and capacity for dish processing

Stationary machines are designed for high capacity and continuous operation, which is essential in restaurants, hotels or canteens, where hundreds of portions are prepared daily. They are equipped with more powerful pumps and larger water tanks, allowing them to maintain stable temperature and pressure even during long-term use, with their performance often exceeding 200 dishes per hour. Portable models are more suitable for smaller businesses, cafes or as a backup, where flexibility is more important than maximum capacity, and their performance is limited by the smaller tank volume and weaker pump.

A practical example from practice shows that in a restaurant with 150 seats, a portable machine would likely not be sufficient to cover the peak lunch time, leading to a pile-up of dirty dishes and service delays. For such businesses, machines like the KAMMAK series designed for industrial use are ideal, offering the reliability and performance needed for smooth operation.

Energy efficiency and water consumption

Stationary machines are technologically more advanced and use water recirculation and heat exchangers, which significantly reduce overall water and electricity consumption per dish. Thanks to their connection to a stable supply, they can precisely regulate the amount of water and temperature according to the set program, thus minimizing waste. Portable machines, which often use simpler heating systems and less advanced pumps, may have higher water consumption per cycle, especially if water needs to be frequently refilled or if leaks occur during hose handling.

Stationary models have lower water consumption per cycle due to precise dosing.
They use thermal energy from the heating phase to preheat the next water batch.
Portable models have higher variability in consumption depending on the quality of water pressure.
Long-term operation of a stationary machine is economically more advantageous due to the lower cost per m³ of water.

It is important to remember that although the purchase price of a portable machine is lower, its long-term operating cost can be higher due to higher water and electricity consumption, which becomes evident especially during intensive operation. When choosing the performance of a KAMMAK machine, always consider not only the initial investment, but also the monthly operating costs.

Installation complexity and flexibility

Installation of a stationary machine is a process that requires a professional, as it involves cutting and joining pipes, mounting drain traps and possibly modifying the electrical supply. This complexity means that after installation, the machine is fixed in one place and its relocation is associated with dismantling and reinstallation, which is time-consuming and financially disadvantageous. In contrast, portable machines are designed to be operated by anyone without specialized knowledge, it is sufficient to place them on a flat surface, connect the hoses and turn them on, making them ideal for businesses that frequently move or change the kitchen layout.

This graph shows that while the stationary installation is a complex process with multiple steps, the portable model is immediately ready for use after minimal actions. If you plan to move it frequently or have a small kitchen where the appliance must be stored out of operation, the portable model is clearly the better choice.

Recirculation principle and heat losses

Stationary machines use a closed water circulation system, where water is pumped back into the tank for heating after being discharged from the filter, minimizing heat loss and energy consumption.

Frequently asked questions

Which type of machine is suitable for small cafes?

For small cafes with low to medium dishwashing volume, a portable machine is ideal, as it takes up little space and does not require costly installation.

Can a stationary machine be moved later?

Yes, it is possible, but it requires disassembling the piping and reinstallation, which is time-consuming and requires the help of an installer.

How do the lifespans of both types differ?

Stationary machines have a longer lifespan due to their robust construction and stable connection, while portable models may be more exposed to mechanical wear during transport.

Conclusion

The decision between a stationary and a portable KAMMAK machine should be based on the actual needs of your business, capacity, and installation availability. While stationary models offer maximum performance and efficiency for large kitchens, portable versions are indispensable where flexibility and quick installation without structural changes are important. Choosing the right equipment ensures smooth operation of your business and long-term satisfaction with the investment.
