Chiller units

Our customised chiller units for cooling water or glycol/brine as indirect cooling medium are used for the most diverse of process cooling and air conditioning applications in all performance ranges.

In accordance with your specific requirements – e.g. in terms of dimensions, noise emissions, supply temperatures, ambient conditions, operational safety /redundancy or factory specifications – we develop your individual chilled water solution.
By using speed-controlled compressors and chilled-water pumps, electronic expansion valves and efficient EC fan technology, we realise maximum performance parameters. Our refrigerants are environmentally friendly and future-safe with low GWP values (low-GWP refrigerants).

Due to our flexible system construction, we can realise designs according to your requirements – for indoor and outdoor installation, as an air-cooled version with an external condenser or as a water-cooled solution including dry cooler. Modular construction for separate insertion in difficult-access areas is also possible, e.g. for replacing existing systems. Naturally, our scope of services also includes required hydraulics equipment such as primary/secondary pumps, buffers/hydraulic separators or control valves.

Optionally, we can also integrate a free-cooling system for saving energy in winter operation or a heat recovery system for using freely available waste heat, e.g. for heating of production processes, process water or buildings.
