Our products

Product category: Cooling equipment

Energy optimized cooling system with heat recovery

Since the operating costs of cooling and refrigerating systems over the service life are a multiple of the investment costs and further increasing energy costs can be expected, energy optimization is of highest priority to us. For example, particularly much importance is attached to energy-efficiency in the selection of system components such as pumps and cooling energy generators. In addition, the systems are optimized with regard to fluidics to minimize the energy demand of pumps.
Furthermore, a process-optimized control system makes sure that the interaction of all system components is organized in the best possible manner. Economy and ecology equally profit from the integrated system optimization.

Cooling system technology of a production plant for medical instruments with winter relief and heat recovery

Experience from decades in all areas of energy supply and process engineering is included in the development and optimization in the plants planned and produced by us. Our customers profit from this by a continually optimized system technology at the highest possible reliability and an efficient price. Each cooling or refrigerating plant designed by us is individually adapted to our customer's requirements and optimized to the energy consumption in the best possible manner. A system concept is developed by our experts after a detailed system analysis, taking the specific operational requirements into account.

Product category: Cooling equipment

Modular energy center with a process-adapted two-circuit re-cooling system.

The demand for modular energy centers has considerably increased during the recent years.
The reasons for this development may surely be a quick availability, flexibility and the space-saving design of these powerful ONI systems. From the supply of cooling and cold water to heating power and compressed air including pumps, tanks and controllers, the entire technology is integrated into modular units in a compact and space-saving manner. Hi-tech and quality products are combined in our modular energy centers.
