The new and compact DELTAFlex design enables the end user and the operating company flexibility with a small foot print, particularly when large air flows are of concern.
The modular version of DELTAFlex can handle air flows of up to 400,000 m3/h. The DELTA2-filter elements are vertically installed into the DELTAFlex housing. Depending on the requirements and the filter unit design, the filter elements can be arranged in a single row, in two rows or even up to three rows or more.
APPLICATION
The DELTAFlex filter units are suitable for the separation and / or product recovery of fine, adhesive or even abrasive dusts.
Powder Coating:
Constant air flow and laminar air flow are of significance for optimal and efficient results during electro-static powder coating. With DELTA2-filter element a contamination free product recovery of overspray is given as contaminating of the powder through the use of the Herding? filter element is excluded.
Steel Pipe Production:
The production of seamless steel pipes demands maximum up-time of the whole manufacturing process including also the filtration system. It is to be assured during the forming, rolling and gauging of the pipes that the extraction of the steam, metal oxides and graphite is continuous and steady as these contaminants may adversely affect the pipe surface quality.
Extraction of Welding Fumes:
When extracting welding fumes, produced by partly oily or greasy sheet metal, the capturing method and an effective filtration are significant since most times the clean gas is returned to the work area. Depending on the state or quality of the sheet metal a pre-coating material may be necessary, which is applied as a filter aid onto the Herding? rigid body filter element DELTA or DELTA2 by means of the Herding? MultiCoater.
Toner Dusts:
During the production and aspiration of toner powder for color cartridges the filter unit has to be carefully selected with regarding the ATEX-regulations and other safety aspects (classification of -zones). Should an explosion hazard be of concern, the DELTAFlex unit can be equipped with a horizontally or vertically installed rupture disk. Furthermore an explosion discharge duct can be optionally added to vent the pressure of a possible explosion away from the filter unit into a low risk area.
As an alternative to the rupture disk, the unit may be equipped with an explosion suppression system which utilizes the injection of dry extinguishing powder.
More applications for the DELTAFlex are to be found in several industries like:
Automotive, Chemical, Pigments, Glass, Plastics, Food, Metal Processing, Pharmaceutical, Recycling, Stone, Cement, etc.
