Up to 2 x 48 nozzles for a maximum spraying width of 4,800 mm ? those are the dimensions for which spray.xact 5000 was created. The special spray lubrication system for large presses provides for airless and economical oil application to blanks which are the preferred solution for the outer skin panels of vehicle bodies. The heart of the system is the proprietary spray valve developed by technotrans. It is electronically controlled and emits spray pulses. Thanks to a high spraying frequency, the result is a constant and homogeneous spray pattern on the sheet metal surface. There is also no need for an extraction system. The oil quantity can be adjusted precisely simply by changing the spraying parameters. In addition, adjustment is completely straightforward due to the fact that it is 100% electronically controlled. Furthermore, spray.xact 5000 excels thanks to its easy access to all of the components for maintenance or in the event of malfunctions and straightforward installation of key components for the emergency mode.

spray.xact food is a high-performance, technically advanced spraying system for low-mist, precise and economically efficient application of media. The solution is an enhancement of the system based on the proven technotrans spraying technology originally used in punching and forming applications. It has been specifically tailored to the requirements of food producers. Conventional compressed-air operated systems are often associated with the generation of aerosols which are inhaled by employees and accumulate as deposits in the production environment if extraction systems are not used. spray.xact food enables users to prevent these problems: The temperature-controlled valves ensure optimum viscosity of the applied medium by means of precise temperature control. In addition, the unit offers outstanding flexibility. All the relevant parameter settings, from the temperature to the spraying quantity, can be adjusted to actual requirements by the user on each individual spray valve. Moreover, spray.xact food is also available as a mobile version.

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. Benefit from our experience and the reliability of our proven technology. technotrans will find the optimum solution for your specific application.
