Salt Fog Test Chamber, For Industrial Use, Power : 6-9kw

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 (Fiber Reinforced Plastic) Moulded Sheet. The Interior & Exterior Sides of the Chamber are Acid Proof, Alkali Proof, Impact Proof and easy to clean. 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. A full top opening door will be provided for ensuring maximum working space inside the Chamber.
• Air-Saturator : It is provided to supply heated and humidified clean air, over 90% to 98% 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.
• 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 (Fiber Reinforced Plastic) Moulded Sheet.
• Solution Heating : Heating of solution in the Solution Tank by a special type of Glass Heating Element (two nos) fitted in the Solution Tank.
• 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.

The Control Panel will House :

• RH and Temperature Controller-cum-Indicator for Main Chamber.
• PID Temperature Controller-cum-Indicator for Air Saturating Tower.
• PID Temperature Controller-cum-Indicator for Solution Tank.
• Pre – Set Timer, ON/OFF Switches, MCB, Electronic Relays, Indicating Lamps & Time Totaliser
• pH Indicator.

Safety Device
Audiovisual Alarm start at the time of shortage of water in both the Saturating Tower and Solution Tank.
Wiring
All wiring will be as IS code.  Channel type wiring will be done with suitable current rated copper wires.
