Ice rinks
Every icemaster's greatest fear is an ice surface, which is not tight and smooth. On one side this is influenced by the cooling system, on the other side by the stability of the iceresurfacer. To optimize the stability guarantee Zamboni has chosen to build a chassis at her own factory, which is so stiff that torsion is almost impossible, by which Zamboni is the only one on the market. The planing part has been backlash mounted and vibration is avoided by correct adjusting of the leaf springs. This adjustment is necessary to reach the correct working pressure. Especially on a Zamboni the weight distribution over the wheels is in perfect balance, which also contributes to the perfect stability. It goes without saying that every imbalance in the machine does not lead to the desired ice quality.

The Zamboni Iceresurfacers are world-wide used because of:
- perfect ice quality guarantee
- simple adequate operation
- very high reliability at continuous use
- very high technical lifetime (expected lifetime average of 20 years)
- a perfect service and spare parts provision
- available in electrical, diesel, LPG and gas version

Only this Ice resurfacer deserves the name ZAMBONI.

Filter technology
One of Imbema Controls' most important filter applications is intake air filtration for turbines. Turbines use enormous quantities of high quality cooling and combustion air. Bigger dust particles of > 10 µm can cause erosion of the rotor blades. Particulates of 0,3 to 5 µm causes an impact on the rotor blades, by which the effectivity eventually will be reduced and in the end the turbine has to be cleaned. The rough parts can be removed easily by the first filter. However, particulates are more difficult to remove.
The filters' resistance to overcome takes approx. 1,5% of the generated power. Although a small percentage, but it is absolutely a huge amount. The fuel represents 80 to 85% of the total costs for energy generation, while the other costs are hardly influenced. Therefore, all things related to fuel savings can directly be translated into financial revenue. The correct choice and timely replacement of filters effect the fuel consumption so much, that the purchase price of filters is hardly relevant compared to the achieved fuel savings. A well designed filter house, therefore, has a number of filter phases, increasing from rough to fine to also achieve a high filtration rate at a low pressure drop.

The following phases can be distinguished:
The filter house often has roofs and louvres to stop rain and other kinds of sediments. Intake grates stop paper, birds etc. Together they are the first phase of filtration.
