mobile centrifuge separator | presented by E&W Industrial Service Asia Co.,Ltd.



One for All – the mobile solution
STA Separators are very compact and space saving, on top of this they can be done mobile, to be even more all-purpose and flexible. Due to their own back flow pressure there is no installation works necessary apart from connecting two tubes.

A good spin on separation performance ?

The fluid-dynamically designed accelerator hub and the big effective flow radius help applying the high rotor accelerations of up to 2.000 g effectively on the liquid and the particles to be separated. This is why STA Separators reach significant grade efficiencies for particles down to 1 to 3 µm. For high flow rates up to 250 l/min strong drives are selected accordingly.

It’s running already?

So quiet you wonder why it’s not running. Thanks to its direct drive and the silicon sand filled double casing the separator generates a very low noise level; only 70 dB(A) on the model S-15. Sound-damping housings are rarely necessary.
  


Not afraid of hot acid

STA Separators are available in different material pairings. For demanding applications in medical or food-related industry, or for use with hot and chemically aggressive media all models can be stainless steel built, in both 304 and 316 Ti alloy, accordingly combined with special sealing materials.

Right and Tight

the high acceleration forces also result in an optimum compression of the separated solids. The sludge is dry and can be reasonably disposed or even recycled. 

A matter of mud

If you decide to go for a centrifugal separator as your separating system, most parameters relevant to filtration, such as shape and composition of the solids, become forgettable. Unfilterable additives like greases and polish, or those problematic ingredients in cast alloys namely graphite and silicon just get removed as well. More examples: chlorinated drawing oils, molybdenum, scales, paint sludge, phosphates, organic slurries, …

hydraulic part cleaning - aqueous industrial parts washer



environmental friendly water based cleaning
 without using hydro carbons or chlorinate hydro carbons
 # aqueous industrial part cleaning # of hydraulic parts

 


Every day, manufacturers of parts with a complex design face the challenge of how to clean difficult-to-access parts such as undercuts, blind bores, or intricate channels efficiently and reliably. In most cases, valuable resources and much time are invested with the result that the easy-to-access parts are “over-cleaned” before the cleanliness of the hidden interior contours meets the strict specifications.

For these requirements, MAFAC developed a new process for targeted cleaning, rinsing and drying of certain sections of the part, addressing in particular manufacturers in the hydraulics and die casting industry.

MAFAC is one of the leading Company manufacturing # aqueous industrial part washers# which is a important step in manufacturing as well it helps to protect our environment as we waive the use of HC and CHC products.

Hydrocarbons and chlorinate hydrocarbons

as solvents led in the past to various ecological problems (soil contamination, groundwater contamination's, contribution to the acid rain) and health problems (industrial safety, stress for adjacent rooms).

Regarding their environmental compatibility and costs the aqueous cleaners have the best results, Mafac manufacture Energy efficient machines to reduce operating cost.

Cost-efficient heating of cleaning agents – with the heat exchange module MAFAC HEAT.X

Cost-efficient heating of cleaning agents – with the heat exchange module MAFAC HEAT.X

Alpirsbach Black Forest Germany  in January  2016 –
For low-energy operation of their aqueous parts washers, MAFAC developed the new heat exchange module MAFAC HEAT.X. The compact unit heats cleaning agents using externally available heat instead of expensive electricity. 
In view of rising energy costs and the constantly increasing competition, the sustainable operation of production lines is becoming more and more important. This situation, as well as the endeavour to reach the climate targets, calls upon companies to identify and utilize the energy-saving potential on their shop floors.The new heat exchange module MAFAC HEAT.X gives companies the chance to improve the energy consumption aspect of their parts cleaning process, and to efficiently reduce the energy costs.
Intelligent heat exchange
The MAFAC HEAT.X module works with a highly efficient heat exchange process. The available heating agent flows through a coaxial heat exchanger, while the cleaning agent which needs to be heated is simultaneously conveyed through the pipe-in-pipe system of the heat exchanger. The waste heat of the heating agent increases the temperature of the cleaning agent, which is then returned to the cleaning process. Because the liquids flow in opposite directions, the heat exchange is almost free of loss.In this way, the electricity used for heating can be replaced by alternative sources of energy. The MAFAC HEAT.X module is suitable for supplying heat from three different energy sources/concepts:
  1. Hot water from heat treatment,
  2. from co-generation,
  3. or from regenerative water heating applications (solar heat).
Positive energy balance and process reliability in parts cleaning
In particular companies whose production processes generate much waste heat, such as foundries, benefit from the new heat exchange module by optimising their energy balance in the sense of an energy management system pursuant to DIN EN ISO 50001. By increasing the temperature of their cleaning agents using waste heat to feed a heat exchange system, they do not throw away valuable energy but supply it to a sub-process. This reduces their energy consumption by up to 60 % and lowers their CO2 emissions (617 g CO2/kWhEnd according to GEMIS-Strom-Mix Deutschland). 
The MAFAC HEAT.X modules guarantees constant heat exchange and thus the process-safe operation with a continuously excellent cleaning performance.This is achieved by a highly turbulent flow in the coaxial ducts, and the smooth surfaces in the pipes which are free of edges and deposits.The high degree of turbulence promotes the heat exchange, and also have a self-cleaning effect. As another advantage, the highly integrated power density of the MAFAC HEAT.X allows the module to provide the heat derived from heat exchange much faster than with conventional electrical operation. This reduces ramp-up times and accelerates the compensation of temporary loss of temperature, for example when inserting large components. Another benefit: The highly robust coaxial technology of the module requires little maintenance.
The heat exchange module is suitable for flexible use. It can be used in mixed with electricity and water and can be connected to different machine types Retrofit kits make the connection very easy, also for older machines.
The new heat exchange module MAFAC HEAT.X was developed for warming up cleaning fluids by means of external heat supplied to them. In this way, the energy consumption for bath heating can be reduced by more than 90%.The new heat exchange module MAFAC HEAT.X was developed for warming up cleaning fluids by means of external heat supplied to them.
