Standard Salt Fog Chamber Options

Suggested Standard Salt Fog Chamber Options Available

Combination Jet Exhaust & Wet Bottom Drain Assembly

This assembly is for ventilation and draining of the fog and condensate that exits the chamber. Consists of jet exhaust unit, water pressure regulator and necessary fittings. As the fog leaves the chamber through the exhaust port, it is washed down the drain using a constant spray of water (5 PSI). The Wet bottom drain provides an inverted trap for the cabinet to drain but not exhaust. The height of the inverted trap determines the amount of condensation that will build up on the chamber floor. Requires hook-up to plant city water supply line. (C260301 for #23, 24, & 410)

Jet Exhaust Recirculating System

This option is also used for the ventilation of the chamber. It is designed to be used where a it is important to minimize water consumption. Rather than flushing the exhaust fog and water down a drain continuously, this fog and water is washed into a holding tank and reused to wash down more fog. This option will conserve water and reduce operating costs. This option is commonly used in combination with a Wet Bottom Drain Assembly.

Wet Bottom Drain Assembly

The Wet bottom drain provides an inverted trap for the cabinet to drain but not exhaust. The height of the inverted trap determines the amount of condensation that will build up on the chamber floor. This build up of condensation on the floor of the chamber will increase the relative humidity in the chamber during the test.
High Temperature Package

Includes special heaters, CPVC internal box, and insulated cabinet and cover. Allows for the chamber to run at temperatures up to about 140 oF (160 is also available).

  1. Polypropylene cover (replaces the PVC cover)
  2. Insulation panels
  3. Rubber liner (replaces the PVC liner)
  4. CPVC dispersion tower (replaces the PVC tower)

All of the components on the chamber that would not stand up to 65 oC temperatures are replaced. The chamber is insulated to assist the chamber heaters bring the chamber up to temperature. The insulation panels also keep the user from being burned at these elevated temperatures.

This option is helpful to those labs that require or desire increased test temperatures. The standard chamber can test in temperatures up to 50 oC however the longevity of the chamber will suffer. Any testing above 40 oC on a continual basis is a good reason to have this option. Tests such as ASTM B360 (CASS testing) is a great candidate for this option.
Horizontal Dispersion Tube

This option will move the dispersion tower from the center of the chamber to the back wall of the chamber. The fog is dispersed from a “T” shaped horizontal dispersion system from the back of the chamber towards the front of the chamber. This option opens up the center of the chamber to provide maximum space within the test chamber. The slotted openings in the horizontal tube have adjustable baffles to assure uniform fog dispersion control. This assembly replaces the vertical dispersion tower.
