Composing RUVAC WH WHU


Roots blower

Maximum efficiency, reduced pump downtime

The RUVAC WH / WHU series pumps are high throughput, hermetically sealed, water cooled roots blower pumps with high efficiency motors that provide optimum price-to-performance ratio and high pumping speeds up to 9800 m³/h @ 70 Hz with optional frequency converter. Both motors and oil reservoirs are water cooled thereby perfectly balancing the internal temperature management of the pumps. You benefit from significantly lower oil temperatures and hence a longer oil service life.

The potted motors replace the can for hermetically sealed drives delivering increased efficiency equivalent to the IE2 or IE3 requirements of the efficiency standard. As the potted motor design does not require bearings, service intervals are longer and pump failure is minimized.

RUVAC WH pumping speed can be increased and pump down time can be shorten by using optional frequency converters.

RUVAC WHU pumps are equipped with a bypass line and may be operated at its maximum power from atmospheric pressure. The WHU is equipped with improved valve technology for maximum efficiency in short cycle operation. The integrated bypass line allows for the WHU pumps to be operated starting at atmospheric pressure while the unique control flap provides extreme contamination resistance.

RUVAC roots blower deliver high capacities for applications such as architectural glass coating where short cycle time are critical. Backed by the proven oil sealed SOGEVAC pumps or the dry compressing DRYVAC and SCREWLINE pumps, the RUVAC pumps deliver the shortest pump down time for loadlock chamber applications and optimized pumping for trouble-free vacuum in process chamber applications.

User advantages

Trouble-free operation with toxic or corrosive media owing to the hermetically sealed motor

Compact design with minimized space requirements

No shaft seals towards atmosphere, therefore high reliability, long service intervals and no oil leaks

Easy system integration

Optional frequency converter for high pumping speed up to 9800 m³/h @ 70 Hz

Lower energy costs with innovative motor technology

Integrated water-cooling system for installation in air-conditioned production site

Stainless steel parts in contact with cooling water (corrosion-free)

RUVAC WH / WHU roots blowers are used in many applications to achieve the shortest possible cycle times such as high-speed food packaging.

RUVAC WH  /WHU roots blowers quickly reaches a pressure of less than 10-3 mbar for thin film coating applications, prior to the vapor deposition processes or degassing electrolytes for Lithium-ion battery manufacturing processes.

RUVAC blower is also used for the manufacturing of silicon mono-crystal, the basic material for the manufacture of semiconductors and solar cells. We would be pleased to offer you our extensive product and applications support and know-how.
