Central cooling systems

Modularity and flexibility taken to the next level: ECOtec.chiller is the new modular platform for bespoke, energy-efficient cooling solutions with a convincing power density for a wide range of industries. pure.line is the cost-optimised, compact variant of the chiller that can be configured in line with specific requirements by way of a user-friendly microprocessor-based control panel. Even the standard version of the pure.line system is equipped with an easy-to-clean aluminium fabric air filter. A filter monitoring system indicates when the air filter needs to be cleaned. As a result, sensitive machine assemblies are effectively protected against soiling and the service life of the cooling medium is increased. The areas requiring maintenance are all arranged at the front and a fill level indicator which can be checked from the outside ensures the easy handling, operation and maintenance of the unit. Additional advantages include the space-saving design in a modular housing and the small CO2 footprint.

The xtend.line is the highly flexible variant of the new modular ECOtec.chiller. Its area of application includes all types of processes where the temperature and fluids play an important role ? regardless of the industry. Thanks to numerous equipment options, the thermal management solution can be specifically adapted to a wide range of requirements, e.g. by way of additional cooling circuits, media or an outdoor option. However, the xtend.line does not only offer a high level of flexibility. Its energy efficiency and power density are also noteworthy. The refrigeration consumption is up to 60% lower than with conventional solutions. Depending on the ambient temperature, the unit automatically adjusts the optimum operating point (SEPR value) of the complete system in terms of its energy efficiency. The result: cost savings and a reduced CO2 footprint. Another striking feature of the solution is its high level of operational reliability: Additional sensor systems in the refrigeration circuit as well as in the cooling medium circuit ensure continuous process monitoring.

CENTRAL WATER COOLING - AN EFFECTIVE ALTERNATIVE Stable humidity and temperature are a fundamental requirement for the production of high-quality products, especially when it comes to repeat jobs. Heat sources have a negative effect on the fragile balance between relative humidity and temperature. In order to counter this effect, water-cooled peripheral units are widely used these days. Based on over 50 years of development and project experience, technotrans ensures the reliable supply of these units with cooling water. The productivity in the production area increases continuously. Water cooling has been the standard method for motors in automotive engineering for a long time. However, water can also absorb the waste heat of the machine and withdraw it from the production area. Compared to air cooling, water cooling requires only small pipe cross-sections for a high level of performance, which is due to the special physical characteristics of water. The cooling of highly precise machines is indispensable these days owing to their power density. Studies show, for example, that the cooling of drive motors and cooling lubricants accounts for up to 50 % of the total power input. One major cause: every machine has its own cooling system, thereby representing an isolated supply point. Our solution: a central system combines these isolated supply points in a cluster and aligns the capacity reserves by way of a superordinate intelligent control system. The selection of the cooling method should always be based on the requirements of the components in need of cooling and on the climatic conditions on site. In general, free cooling is the method of choice. This method does not require any refrigeration unit and is characterised by particularly low operating costs and high reliability. Special applications requiring a constant water temperature make use of water chillers. Water chillers with air-cooled condensers and a compact design for outdoor set-up are used for the cooling water supply with a feed flow temperature between 6 and 20 °C and outdoor temperatures up to 45 °C. An integrated buffer tank and circulation pumps eliminate the need for a separate pump cabinet. Available with cooling capacities from 25 kW up to 150 kW, with hermetically sealed scroll-type or semi-hermetical reciprocating piston compressors, various cooling agents, different sound pressure levels and more options. A combination system with integrated free cooling enables annual energy cost savings between 40 and 60 %, depending on the desired cooling water temperature and the climate on site. technotrans recooling systems are being used throughout the world.
