LOFT vacuum evaporators in comparison to other evaporators

A comparison of vacuum evaporators from different manufacturers is only possible to a certain extent, as many manufacturers use different standards, test procedures and units in describing the performance of their evaporators.

 

Our intention is to inform you such that you know what to expect in your specific application. Theoretical values for operation with unpolluted inlet water, which have no bearing whatsoever on your subsequent operations, are misleading and stand in contrast to our policies of transparency and verifiable performance.

 

When buying an evaporator, the following points should be taken into account.

  • Is the nominal throughput capacity sufficient for your expected wastewater quantities?
  • Are the capacity specifications provided for the evaporator valid for your wastewater and guaranteed?
  • Is the energy consumption specified for the evaporator valid for your wastewater and guaranteed?
  • Are concentrate specifications provided for the evaporator and guaranteed? For example a post-evaporation concentrate water content resulting from emulsion evaporation of < 50 % (determined by the Karl Fischer method)

 

All of the above points interact with each other and must be fulfilled.

If this is not the case, the expected performance, costs and the entire application of the evaporator following start up may differ substantially from expectations, providing unpleasant surprises.

 

 

When comparing performance spcifications, be certain that you are in fact comparing apples and apples.

And have the potential supplier provide a guarantee for the performance specifications valid for your specific wastewater.

 

 

Our evaporator systems are designed with a focus on realization of large heat transfer surfaces. These large surfaces provide a variety of benefits including:

  • guaranteed operating performance over the entire cycle including final concentration
  • less frequent cleaning and therefore reduced downtime due to poor or impaired performance
  • reduced concentrate disposal costs due to higher concentration and therefore reduced volume
  • constant energy consumption even when operating evaporator near capacity limits
