Working System / Options

All front door opening- and chest cabinets can be furnished with the following working systems, provided there are no limitations to space, design or material properties Working system CON CH High Humidity ISO 6270-2 CH (DIN 50017 KK) Working system CON AIR Aeration “AIR” ISO 6270-2, ISO 6988 DIN 50014, (DIN 50018) Working system CON ADO Automat. Door opening “ADO” ISO 6270-2 DIN 50014 (DIN 50017)

Demineralised water is warmed up Ambient air (18°C-28°C /40- 60%rel. humidity) are blown into When the preselected test time of the high humidity phase elapsed the front door is opened automati- cally thus the specimen are dried by ambient air.Options: to usually 40°C and evaporated inthe upper space of the testing chamber. Options: CTD system "regulated condensa- tion" Increased working temperature - to 60°C, or 70 °C the testing chamber by means of a built-in fan and distributed evenly by a distribution pipe thus there is an even drying of the specimen Options: CTD System “Regulated Condensation” “Regulated Condensation” Increased working temperature- bis 60°C, or 70 °C 5 % Sodium chloride solution or amodified test solution is sprayed into the testing chamber by com- pressed air to form a fine mist at 35°C (SS)or 50°C (CASS). Options: Increased working temperature - bis 60°C, or 70 °C Automatic water refill

Working system SAL Salt spray ISO 9227 DIN 50021 SS, ESS, CASS Working system WL Forced Air drying Corporate standards Working system A-KES Automatic SO2 Dosing” ISO 6988 (DIN 50018)

Ambient air is heated up and intro- duced into the test chamber by a built-in fan. An air guiding pipe provides an uniform flow through the chamber thus there is an even drying of the specimen. Options: Rotating speed variable fan For conducting tests using pollu- tion gases such as SO2, the gas is introduced into the chamber from the storage bottles, metered by a calibrated mass flow meter. Kesternichtests can be carried out day by day without any manually operation. The humid atmosphere is formedby spraying of water in the testing chamber. The humidity is meas- ured by a capacity sensor and con- trolled by a microprocessor controller “Prohesion Test (PR)” for intermit- tent working mode. Automatic switch on to the second test solution tank. CON CH -System for constant high humidity tests Cleaning of the testing chamber, Cleaning of the tubing system

Working system RF Controlled Humidity I Corporate Standards, DIN 4570 Working system ARF Controlled Humidity I Corporate Standards Working system Alternating Dipping “WTP” Corporate Standards

The humid atmosphere is formed by spraying of water in the testing chamber. Additionally a industrial steam generator supplies steam to achieve major relative humidity values. The humidity sensor is mounted outside the testing cham- ber to prevent from contamination for instance by salt spray. During the humidity testing phase the Specimen can be dipped into rea- gent solutions during specified duration and exposed to humid atmospheres inside the testing chamber. sensor is pushed into the chamber. Due to the high sensitivity of the sensor the humidity can be con- trolled by the PLC with a high ac- curacy.
