Advantages of our VapoFan for Mechanical Vapor Recompression

Vertical blower design for compact evaporator systems

The VapoFan is ideally suited for integration into a compact evaporator system: with minimal space requirements, independent installation locations and less energy consumption. 

The perfectly harmonized drive unit is one of the reasons for the excellent efficiency. It consists of a synchronous motor specially developed by PILLER and a matching frequency converter in various capacities. A wide range of customer requirements can thus be covered and served.

The design of the VapoFan as a radial blower ensures reliable and smooth operation. The clearance dimensions between impeller and housing are sufficiently large to avoid any contact. Compared to rotary lobe blowers, PILLER VapoFans have an additional advantage: the flow is much more stable and the efficiencies remain constant within the wide operating range. The efficiency is up to 86% due to the ideal matching of motor and blower. 


Our VapoFan at a glance:
  • Efficiency of up to 86 percent  
  • Designed for applications with mass flows from 200– 9,000 kg/h 
  • Serial connection of our VapoFans achieves highest temperature lifts 
  • New capabilities of energy and cost savings 
  • Radial blower design ensures reliable and smooth operation 
  • Fast implementation 
  • Minor maintenance requirements

Build for low mass flows

Performance summary of our VapoFan

The VapoFan is the ideal solution for any steam compression with low mass flows. This includes applications of Mechanical Vapor Recompression such as 
 

  • Distillation,
  • Crystallization,
  • High Concentration (including ZLD, applications for wastewater free production),
  • Drying,
  • or the use as booster for partial flows.


Efficient energy recovery solution for the process industry

The combination of limited energy sources with increasing prices and the goal to reduce greenhouse gas emissions are pushing the process industry to find more efficient solutions for its energy demand. Our VapoFan supports you to secure the optimum MVR vapor compressor solution for your specific process requirements.

The machine offers an ideal solution to upgrade existing plants but also for new plants and process extensions. The advantages: low space requirements, mobility of the equipment and fast implementation.  

Another advantage our VapoFan offers, is that no grease or oil can leak into the wetted area. Therefore, the blower is perfectly suited for applications in the food industries and for the pharmaceutical industries, e.g.  Water For Injection (WFI).

The very flexible range of applications, due to the modular construction, offers numerous possibilities – also in innovative and visionary projects. In water treatment, the VapoFan is also suitable for unusual locations due to its compact design; for example, on board of ships or in the smallest modular plants for the treatment of industrial wastewater.
