Due to its low noise level the robust vacuum pumps series ensures undisturbed working. Furthermore the cool running CRVpro pumps guarantee less oil consumption and a slowed down corrosion. By diluting chemical vapors with a larger oil chamber there is also a reduced risk of chemical attacks and oil breakdowns.

Convincing with a modern and compact design, the CRVpro vacuum pump series fits different performance requirements perfectly and is for example applicable to freeze dryers, vacuum concentrators, schlenk lines, glove boxes, industrial applications, HVAC and vacuum ovens.
Pascal 2021 HW is suited for applications where water vapor is expected such as low temperature sterilization and drying. The two-stage rotary vane pump has a gas-ballast system that allows the pumping of large volumes of vapor without condensation inside the pump. This prevents accumulation of fluid that would adversely affect the service life of the pump and the pump oil. It utilizes special materials to resist aggressive chemicals such as hydrogen peroxide. The pump is ready to deliver vapor in just a few minutes due to a customized temperature-management system. It has a safety device that impedes the water from entering into functional sections of the pump if the steam capacity is inadvertently exceeded.
