lt is a model of the chiller range”Hybrid” for an installation in Germany. These coolers are suitable for cooling glycol water for industrial processes. They are compact chillers, multi-Scroll circuit with inverter technology with continuous capacity of power with an important energy saving; With electronic EC fans, electronic thermostatic valves. Hydraulic module on board, with storage tank and centrifugal recirculation pump.

Is important to highlight the high technological content of our machines, where electronics are increasingly predominant, in favour of a high energy saving compared to a traditional on-off operation of the compressors. The inverter technology for the compressors makes the thermoregulation + effective in the face of an important reduction of the electrical consumption, especially at partial loads.
The control unit of the chiller, equipped with a 4.3 “LCD colour display, manages the temperature of the fluid. Alarm signals are reported immediately through a serial communication in Modbus between the chiller and the press system. An intranet connection allows you to monitor the operation, or any anomalies, remotely.
This cooler has been commissioned by our Spanish client, manufacturer of large mechanical presses for the printing of automotive components. The purpose was to provide a constant temperature of a glycol water at 23 °c with a precision of +/-1 °C, and a cooling capacity of 400 kW. The important inertial accumulation of the chiller has been sized to compensate for the thermal load peaks due to the sudden and non-constant cycle work. The cooled water goes to thermoregulation the temperature of two large Siemens engines applied to our customer’s printing machine. The fluid through the ducts in the motor itself maintains the mechanical part. Any overtemperature, and consequent thermal expansion of the metallic materials, cause failure in the printing process where the precisions in the game of the printed artefact are at a hundredth of micron.
The final installation took place in northern Germany at the German plant of an international group leader in the production of automotive components (such as steel frames, body parts, metal components,…).
