Intelligent Systems

Intelligent Systems

Due to optimal adaptation of all components, the application limits of our systems can be fully exploited. Therefore, we rely on high quality products from long-standing, local suppliers. All engines may be equipped with energy-efficient frequency inverters or EC technology. The control system based on PLC ensures the best relationship between demand and supply of capacity. Operating conditions are indicated on the touch panal which enables also the input and output of all essential parameters.

In addition, the air conditioning systems can be equipped with a free cooling module, including all necessary accessories. Operating costs can thus be reduced significantly. Next to cooling function, our units can be used for heating as well. Intelligent interconnections ensure that the respecive needs are covered reliably.

Design Options

Air-cooled chillers are used for cooling fresh air and/or outside air in the most varied temperature ranges. Normally the units are desgined as split system for external evaporator in a ventilation system or as recirculating air unit. Re-cooling is realized via air-cooled condensers, glycol coolers or cooling towers. Typical applications are office buildings, surgeries, hotel rooms or for private use. Depending on demand, the chillers are available with various capacities with 1 or 2 refrigeration circuits. 
In order to find the optimal solution, we concentrate on the overall view of a system, irrespective of processes being of an industrial nature or cencerned with air-conditioning. Moreover, customer-specific adjustments can be made. Space-saving desgins, special insertion and installation situations, very low sound level, datailed documentation, special factory regulations – special requirements can be implemented individual, fast and flexibel.

Benefits

  • Conditioning of fresh and/or outside air
  • Decreasing operating costs
  • Easy handling due to integrated hydraulics
  • Sustainability by high energy efficiency and low charge refrigerant
  • Reduction of direct and indirect CO2 emissions
  • Increase in attractiveness of buildings

Components & Accessories

  • Scroll, screw and reciprocating compressors with integrated frequency inverter
  • Air-cooled evaporator
  • Air-cooled or water-cooled condenser, cooling towers
  • Refrigerant accessories
  • Stable profile frame with vibration damper
  • Optional sound-absorbing and weather proofed housing

Scroll, screw and reciprocating compressors as single or tandem version with integrated frequency inverter for stepless capacity control and reduced starting current. Electronic expansion valve for optimized refrigerant filling of the evaporator. Reliably closing also in case of power failure. Electrical panel according to industrial standard including all switches and safety components as well as wiring.

Control of the aggregate by programmable logic controller with touch panel for visualization of refrigerant circuit, operating point, application limits, temperature, pressure and the output of plain text in case of malfunction. Inline pump with integrated frequency inverter for electronic control e.g. to enable constant or variable differential pressure, equipped with piping connection and necessary auxiliary equipment.
