PILLER offers a modular solution for low mass flow rates in MVR applications, thus expanding the product range: with the VapoFan series. As a vapor compression unit, PILLER's VapoFan is specifically designed for applications from approx. 200 to 5,000 kg/h mass flow.

Plug in and compress process vapors
The VapoFan is a vertically arranged high performance blower, which is characterized by its solid construction; and which is equipped with a high-speed motor and frequency-controlled drive technology as standard. The Plug & Play system provides a perfect solution.
The blower stands out with reliable performance, high efficiency and a large operating range. All in the well-known – MADE BY PILLER – quality.

Advantages & Benefits

Compact design and excellent efficiency

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


Modular product series in well-known PILLER Quality

  • High quality materials are used for wetted components, among others Super Duplex (1.4501) for impeller and Duplex (1.4462) for casing
  • Wide field of application with just a few variants
  • Designed for applications with mass flows of 200 - 5,000 kg/h with dTs of 5 - 20 K: High-performance in terms of efficiency and temperature rise
  • Modular designed product, with immediately available 3D drawings and layouts, as well as circuit diagrams etc.

Ready for use all-in-one system

PILLER does not simply offer the high-performance blower, but a complete solution consisting of drive system and evaluation electronics developed in-house. The solution is available in single or two-stage as standard and can be modified with additional stages, if required. This allows even higher temperature rises. All components of this modular system could also be adapted to your specific requirements.


Purpose & Performance Data

The VapoFan is the perfect solution for any steam compression with low mass flows. Especially 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.

Energy efficient and visionary

Rising energy costs and increased requirements for the preservation and protection of the environment demand actions. In the process industry, energy recovery is an essential aspect. Common applications can be efficiently engineered and energetically optimized by the VapoFan.
Compact MVR systems offer 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 industry and for the pharmaceutical industry (water for injection, etc.).
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.
