Diluters & Conditioners

Diluters

DEED

The Dekati® Engine Exhaust Diluter (DEED) is a simple, easy-to-use engine exhaust conditioning and dilution system.  It meets all the requirements of EURO 5b/6 legislations for solid particle number count applications, but offers the flexibility to be used for traditional, particle mass measurements as well.  

Dekati

Fine Particle Sampler FPS-4000

A sophisticated two stage dilution system for sampling combustion aerosols and other hot gases.

The FPS features hot or cold primary dilution, adjustable dilution ratio up to 200:1 diluted sample flow up to 220 lpm and real time temperature and pressure correction.

Dekati

Dekati Diluter DI-1000

A low-cost, simple and easy-to-operate device for diluting aerosol and gaseous samples from any source.

The simplicity and robustness of the all stainless-steel design have made it a widely renowned choice for dilution of combustion aerosols.

Dekati

Dekati Axial Diluter DAD-100

A simple and cost-effective dilution tool for any dilution task.

Especially designed for use with Dekati instruments, the DAD-100 is very simple to install into any sampling or measurement system. All-stainless steel design makes it also possible to heat the diluter up to 500°C. 

Dekati

HDS 561

The HDS High Dilution System is used for measuring very high concentration aerosols.  This instrument has a wide range of dilution ratios, adjustable from 1:100 to 1:100,000.  The flow-rate is customized by Topas and adaptable to different volumes, from 28 l/min, up to 100 l/min.

Topas

DIL 540

The DIL 540 Dilution System is a battery operated version of the popular DIL 550 series diluters and is available in either 10:1 or 100:1 dilution ratio versions at 28 l/min

Topas

ADD 536

The Aerosol Distribution and Dilution System, ADD 536, is used in conjunction with an aerosol generator and provides a uniform test aerosol from six different outlet ports with a defined source flow which can be used for verification of operating room protection.

Dilution System for Aerosols DIL 550

The dilution system is designed to accurately dilute aerosols to produce a defined particle concentration and carry out certain measuring tasks.

The main application of the dilution system DIL 550 is in the verification of test aerosols for testing clean rooms. By using the dilution system DIL 554 upstream of a particle counter, e.g. LAP 340, a dilution factor of up to 100 can be achieved. Thereby particle concentrations of  >106 Particles per cf (1 cf = 28.3 l) can be reduced to 104 cf–1. This will put the particle concentration well within the range of standard particle counters.

Dilution System for Aerosols DIL 554

The dilution system is designed to accurately dilute aerosols to produce a defined particle concentration and carry out certain measuring tasks.

The main application of the dilution system DIL 550 is in the verification of test aerosols for testing clean rooms. Compared to the DIL 550 the innovative features are an easy-to-clean compact stainless steel housing and a mobil use by battery-operation (optional also wall power supply). 

By using the dilution system DIL 554 upstream of a particle counter, e.g. LAP 340, a dilution factor of up to 100 can be achieved. Thereby particle concentrations of >106 Particles per cf (1 cf = 28.3 l) can be reduced to 104 cf–1. This will put the particle concentration well within the range of standard particle counters.

Topas

Dynamic Dilution System for Aerosols DDS 560

The Dynamic Dilution System is designed to definitely and reproducibly dilute aerosols according EN ISO 14644 part 3with possibility to adjust the dilution factor.

A simple front panel control knob allows adjustment of the dilution ratio from 5:1 to 370:1at flow ratio from 0.5 to 3.0 lpm.

Conditioners

Dekati Cyclone

An EPA-standard cyclone for removal of large particles from a sample stream.

The cyclone can be used in high temperatures due to the all-stainless steel construction. The Dekati cyclone is manufactured according to EPA standard 201A. 

Dekati

Dekati Thermodenuder

The instrument makes detailed studies of soot particles possible by removing volatiles from automotive exhaust. Removal of the volatiles eliminates unwanted sample transformations. The high flow rate of the instrument makes it an ideal tool for use with ELPI™ (Electrical Low Pressure Impactor) and DMM (Dekati Mass Monitor). 

Dekati

DDU Diffusion Dryer DDU 570

The diffusion dryer consists of an Acrylic tube filled with silica gel with 2 caps on its ends and tube connectors. The aerosol streams through 3 screen pipes surrounded by dry silica gel which serves as drying agent.

Because the aerosol does not get into contact with the drying agent there is nearly no loss of particle material.

Topas

Neutralizers

Electrostatic Aerosol Neutralizer EAN 581

The electrostatic aerosol neutralizer conditions the charge distribution on test dusts as well as other aerosols for example when evaluating separation techniques such as cyclones, filter s or impactors. Charge equilibrium can be controlled by mixing positive and negative ions in a precise manner.

Controllable generation of ions with separate adjustment of both positive and negative ion sources are provided. No radioactive source is required. It's easy to integrate into existing filter test systems and othe test apparatus.

Topas

ADI-100 Neutralizer Housing

The ADI Neutralizer Housing is designed to hold four StaticMaster polonium-210 sources to provide a bipolar ion source for aerosol charge neutralization.  Its 7° tapered inlet ensures uniform flow with minimal particle losses within the particle region.

Sampling System for Pressure Lines SYS 525

The SYS 525 is designed to take a representative sample from sources with mean pressures at up to 8 bar. It effectively decouples the pressure from the measuring point and meassuring instrument with minimal change to the aerosol properties. 

Topas

Rectangular Sampling Probe SYS 529

The sample probes have a rectangular inlet which is gradually reduced to a circular tube connector. 

The design of the probe is based on the ISO CD 14644, Part 3 which defines a maximum width to height ratio of 1:6.

The manufacturing process ensures that all internal surfaces are polished to avoid material deposits and their potential to create false test results.

Topas

Sample Switching Unit SYS 520

The Laser Aerosol Particle Size Spectrometer series LAP can optionally measure two different samples by using the Sample Switching Unit SYS 520. The instrument was especially developed for this application and realizes a quick changing between sample flow I, a flushing routine (HEPA-filter) and sample flow II.

Controlling the switching unit is only possible with the aerosol spectrometers series LAP with sample switching option. If you do not have such a LAP 320/U or LAP 321, Topas can install the needed control output in your instrument.
