""Salt/Cass Fog Test Chamber  
 

Description
The updated models of Salt/Cass Fog Test Chamber specially designed for evaluating the corrosion resistance of the surface treatment of metallic materials by Copper Accelerated Acetic Acid Salt Spray Test Method. It consists of following parts :   Test Chamber

It consists of Cabinet and Lid and is constructed with insulated double structure made of FRP Moulded Sheet. The upper part (triangular shaped lid made of FRP with acrylic glass window) has sufficient space for the mist to accumulate naturally on it and is so shaped that drops so accumulated do not fall on specimen being tested.

Air-Saturator
It is provided to supply heated and humidified clean air, over 90% RH, for Atomization of the solution. It consists of Body (made of stainless steel), Heater, Bubbling Nozzle, Air Cleaner & Pressure Regulator.

Air Regulator
The Air Regulator will maintain a constant pressure of Air at 70 to 170 Kpa.

Air Filter
The compressed air will be passed through a Filter Arrangement to remove all traces of oil and solid matters before sent to the saturation tower.

Lid Sealing
Lid Sealing through Water Seal Method.

Mist Dispersion Atomizer
Atomizer made of Acrylic Glass will be equipped in the Chamber having property of non-choking. It produces a mist of atomized solution, which is distributed uniformly throughout the exposure zone by means of Mist Dispersion Atomizer incorporated with a baffle to prevent dispersion of large liquid droplets. Compressed Air and Gravity Process will help for creation Fog through Atomizer.

Heating System
The Temperature within the Chamber maintained by Heater with Blower System, which provided in-between the Exterior and Interior walls.

Solution Supply Tank
Solution Supply Tank will be provided to supply solution to Mist Dispersion Tower and will be made of FRP Moulded Sheet.

Mist Collector
Two Mist Cylinders are provided for measurement mist quantity. Each has 80 cm² of horizontal area. The condensate is collected in individual graduated cylinders.

pH Indicator
pH Indicator is inbuilt in Control Panel.

Control Panel
Separate Control Panel will be provided located on the Trolley.
The Control Panel will house :-

1. RH and Temperature Controllers-cum-Indicator for Main Chamber.
2. PID Temperature Controller-cum-Indicator for Air Saturating Tower.
3. PID Temperature Controller-cum-Indicator for Solution Tank.
4. Weekly Programmable Timer, Hour Meter, ON/OFF Switches, Fuses, Electronic Relays and Indicating ....Lamps.
5. pH Indicator.

Material
Control Panel, Stand and the Chamber containing other accessories of the Equipment will be made of Stainless Steel 304 qlty.

Wiring
All wiring will be as IS code. Channel type wiring will be done with suitable current rated copper wires.

Power Supply
220/240 V, 50 Hz, Single Phase, AC Mains.

Safety Device
1. Cut-out at the time of water shortage in air saturator.
2. Cut-out at the time of over current in control devices.
3. Low Water Level Controller with Mechanical Floats type-Refilling Arrangement.

 Audiovisual Alarm for Saturating Tower and Solution Tank.
