Case History - Krones Academy Asia
Krones AG, industry leader manufacturer of beverage machinery, has relied on Intelligent Cooling Solutions from Frigel for its new Krones Academy Asia facility.
The Krones Academies are knowledge centers where training on Krones products and technologies is available to customers. The Krones Academy Asia is located in Bangkok and includes, among other equipment, a "Contiform" PET blow molding machine and its HP air compressor unit, both of which required cooling for their operation.
The specific requirement was to design a integrated cooling solution for:
Blow molding machine molds of the Krones Contiform 308 H with chilled water at 7/10 °C and flow rate of 10 m3.
HP air compressor (40 bar) which supplies the compressed air for the bottle blowing process, with water at room temperature (33/35 °C) and required flow rate of 6 m3/h.
Cooling system control: the customer needed to control the entire cooling system from the ground floor where the main Krones Academy premises are located.
PROJECT & SOLUTION
In this case, the need for cooling at both ambient and chilled temperatures, together with the configuration of the spaces and the specific needs of the customer, led Frigel's designers to use a typical "Ecodry system" solution.
The “Ecodry system” is an integrated cooling solution that includes:
A high performance mold cooling unit Microgel for Packaging for the Krones Contiform 308 H, conveniently installed right next to it. Microgel meets the needs perfectly, thanks to its super compact design and quiet operation. The unit includes a water-cooled chiller, accurate temperature controller and high flow booster pump. Being water -cooled, Microgel doesn’t exhaust hot air in the ambient. This configuration also minimizes the number of water pipelines required: the choice of an air-cooler chiller would have required a dedicated set of long insulated pipes, running from the 2nd floor roof to the Academy, at ground level.
- A flagship Frigel patented adiabatic cooler Ecodry – for the overall heat rejection to ambient of both loads, the Microgel and the high pressure air compressor simultaneously. Ecodry is a patented closed-loop adiabatic cooler capable of guaranteeing up to 95% of water and maintenance savings compared to a traditional evaporative cooling tower.
- A Frigel “3PR” remote control panel (PLC) has been installed inside the Academy and has been connected via Modbus cable to the Frigel equipment for the overall system management and supervision. In this way, the operator, via a touchscreen interface (HMI) is able to manage the whole cooling system. All the main variables and functions are integrated in a single control to ensure the best performance and reliability of the system.
