The COREMAKER line of cold box core machines and supporting equipment is designed with simplicity and ease of use as a primary goal. Built by foundrymen for foundrymen, these units are expressly designed for the harsh foundry environment. 

• Can be specified for use with all Amine and SO2 gasses.
• Is complete with built in pH meter. 
• Requires three phase power.

Please note that the Palmer Economy Scrubber is designed with small to mid-size core making operations in mind. Its low cost comes from its simplicity of design and maintenance. From a costing standpoint, the Palmer Economy Scrubber can be used for single core machine installations economically.

Basic Description

The Palmer Economy Series of scrubbers is designed as a simple yet effective means of removing contaminants from core machine purge air. Their use is particularly important in areas of high core gas usage or where environmental concerns are at a premium. Scrubbers work by essentially neutralizing the gaseous components contained within the exhausted air. By neutralizing these components, the scrubber effectively transfers the material from either a liquid or gas into a solid. The scrubber solution is periodically replaced to "refresh" the scrubbing capabilities.

Operation

Fume scrubbing occurs by blowing the contaminated air stream to the bottom of the scrubber's holding tank. At the bottom of the tank is a dispersion device designed to break up the air stream into small bubbles. The smaller the bubbles, the greater the effective area of reaction and odor removal. This is a continuous process giving efficient scrubbing coupled with minimum maintenance.

Before leaving the scrubber, the air stream passes through a polypropylene demister plate designed to remove 95% of entrained water droplets.

To obtain high efficiency of contaminant removal from the gas stream, it is important to ensure that the pH of the scrubbing liquid is maintained at a level that effectively neutralizes the contaminated air. A pH meter is included as standard for monitoring of the pH level. Once the specified pH is reached, the tank is drained removing the solid build-up form the bottom of the unit. Once the sump is drained, a supply of fresh water and either acid or caustic is added to regenerate the system

System Components

Blower - A high volume blower is provided with the unit to pull exhaust air from the core making area and push it through the scrubbing system.

Scrubber Body - The scrubber body houses all necessary components of the fume scrubber. Its primary construction is stainless steel with all liquid contact components made of corrosion resistant materials. The amine version of this scrubber is designed to hold 55 gallons of material while the SO2 version holds 110 gallons (for extended time between charges).

Demister - To prevent the dispersed liquids from escaping to the exhaust air of the system, a polypropylene demister plate is included in the scrubber. This demister effectively removes 95% of all water droplets from the air stream reducing make up water requirements.

Options

CM Series scrubbers are available in many common CFM ranges and can be specified for either amine or SO2.
