We manufacture a few different types of scrubbers to be used in the analytical industry.

The most common types is as follows: (Others available on request)

Rand Series MDPS Multi-Directional Particle Scrubber

The model MDPS Multi-Directional Particle Scrubber was designed with the objective to remove dust from the sample lines of analyser installations on furnaces and stacks.

The MDPS is manufactured from 316 Stainless Steel, and the sample flow through this device is flowing through various restrictions resulting in velocity changes as it works its way through the unit. The internal volume is thus small, and it does not cause unnecessary sample lag time.

The internals are designed to force the sample into turbulence, which results in the dust falling out of the main sample stream.

Condensate formation inside the unit flows downwards towards the process and ensures that the dust is washed out of the unit resulting in a self-cleaning effect.

Features
Removes dust from sample – Eliminate blocking of sample lines with heavy dust content
Self-cleaning – Condensate in the sample will wash the dust towards the process
Low maintenance costs – No parts needs to be removed or replaced
Stainless steel construction – Allows many years of service
Low maintenance frequency – Allows many months before cleaning is required
Can be used on high-pressure – Sample pressures up to 10 Bar

Typical Applications

• Reheat Furnaces
• Arch furnaces gas off take ducts
• Reactors
• Stacks
• Flue gas etc.

Rand Series 500 Volatile Scrubber

The Rand series volatile scrubber is designed with the purpose of scrubbing all volatile compounds out of a liquid sample in order for the volatiles to be measured. However, the design of the unit makes it possible for other uses as well for example as a scrubbing unit to remove water vapour from a sample (this, however, will not ensure a 100% dry sample) and can even be used to remove particles from a gas sample.

The unit is a 500mm long cylinder with a certain material on the inside to increase the surface area. By means of increasing the surface area, all volatile components will stick to the surface and can then be purged off to be measured. Using the concept of an increased surface, we can use the unit as a particle remover or even to remove some liquid from a sample.
