Application

The ACC is designed especially for :

- Power Plants

- Waste Incinerators

- Cement Manufacturing

- Chemical Production Plants

- Gas Production Plants

- Glass manufacturing

- Timber Processing

- Food Processing

Description

The new ACC offers precision, safety and long-term

stability for extractive analytics. The unique cooling and

separating technology of the newly designed coolers

attains low, constant dew points of +3°C and compensates

for operating data fluctuations as well as high thermal

loads.

The very low gas dissolution rate is attained thanks to the

new cooler technology (Patents applied). Both the permanent

separation of the condensate from the gas phase, as

well as the shorter contact time of the gas in the system,

plays important roles.

The new coolers incorporate an advanced structural design.

The new housings are available in wall-mount, 19“-

rack, and mobile design. The coolers can be integrated in

the analysis cabinet without having to leave space at the

side for a cooling air outlet.

Preventative monitoring

An electronic system not only monitors the dew point, but

also the ambient temperature. The fan motor speed is

cooling air temperature dependent controlled. The operation

of the condensate pumps can be adjusted demand oriented.

A service interval alarm and a precautionary

alarm are both issued before an emergency stop takes

place.

Sample gas cleaning

Reliable filtration of particles down to 0.1 micron takes

place in the Teflon-depth filter. A view port allows you to

see when the filter needs changing.

Moisture break-through monitoring

An externally installed moisture sensor controlled by an

integrated electronic control monitors the function of the

cooling system and the condensate pump. Analysers are

protected from condensate breakthrough.

Measurement and adjustment of sample gas flow

With the flow meter and needle valve the sample gas flow

can be adjusted and precisely measured.

Pre-cooling of sample gas with inlet dew point > 65°C

The integrated air-cooled pre-cooler (not shown) pre-separates

free condensate and solid particles which are

discharged through the additional condensate pump.

Elimination of SO3-Aerosols, HCL-, NO2-Concentrations

Samples containing additional water and acid injection

can be accommodated.

Principle

1. More efficient and no energy loss even in high ambient temperatures

■ Coldness transfer through copper and aluminium

■ Thermal conductance values 300 and 204 W/m°K

■ Coldness transferred from the inside outwards

2. High and constant dryness rate even at extreme load changes

■ Hydrophobic surface through PTFE Coating

■ Large condensate drops are formed immediately

■ Spiral performing stream goes downwards

■ Discharge of condensate at the lowest point

3. Low dissolution rate a contribution to more environmental protection

■ Very small dead space, 26 ml

■ Extremely short response time of gas to liquid

■ Large drops have a smaller surface to content ratio

■ PTFE-Coating with low electrostatic current

■ Condensate spiral stream separated from 3 sides

4. Key’s to reliability

■ Chemical resistance thanks to the PTFE-Coating

■ No clogging due to the self cleaning feature

5. Comprehensive testing procedures guarantee equipment reliability.

■ Providing of true inlet dew-points

■ Automatic control of gas mixture at inlet

■ Trace gas measuring by infra-red analyser

■ Data processing and storing

■ Availability of test certificates
