MRW Magnetic Stirrers

Features of MRW Magnetic Stirrers

• Homogenization

• Dissolution

• Dispersion

The high-quality Planetroll MRW magnetic stirrer has been specially developed to meet sterile technical requirements.
A unique feature is the separation of the drive unit from the product space.

Advantages of MRW Magnetic Stirrers

• Equipped with a sensor for speed monitoring, allowing use in ATEX zones 1 and 2

• Easy and quick to clean

• Nearly maintenance-free operation with overload protection

• Complete separation of the stirrer drive from the product

• Low-shear mixing possible

• Space-saving installation on the bottom of the tank

• No stress on the tank lid

• Capable of mixing product residues

• Easily removable drive unit

Special Mixing Technology of MRW Magnetic Stirrers

A key performance feature of the bottom-mounted MRW magnetic stirrer is the contactless rotation of the stirrer, which is generated exclusively by magnetic fields.
Due to the absence of a rotating drive shaft, there is no need for complex shaft sealing in the wall of the mixing vessel.
The non-contact magnetic coupling allows for torque transmission in the range of 1 to 75 Nm.

Thanks to its GMP- and FDA-compliant design, the system is suitable for CIP (Cleaning in Place) and SIP (Sterilization in Place).
The use of an eccentric stirrer configuration eliminates the need for baffles.
In the baffle-free version, magnetic stirrers are particularly successful for homogenizing volumes up to 40 m³.

The mixing head is individually adapted to the application, with various geometries available – including impeller, propeller, and disk agitator designs.

Optionally, the magnetic stirrer can be equipped with a rotational speed monitoring sensor.
This helps to prevent the magnetic coupling’s transmitted torque from being exceeded.

Industries Using MRW Magnetic Stirrers

Due to their low-shear mixing and effortless cleaning and sterilization, the Planetroll MRW magnetic stirrers are especially preferred in sensitive sectors, such as high-tech areas like biotechnology and fermenter construction.

The magnetic mixing system represents the most advanced solution in both the pharmaceutical and cosmetic industries.
Floor-mounted magnetic stirrers are also increasingly used in the luxury goods and food industries, as well as in the chemical sector.
