Vacuum Mixing Cooler - KH
The batch-contact cooler, in sequence to the vacuum mixing dryer. This ensures a tremendous improvement of productivity.

Adding and mixing in of raw materials, that should not be dried, or that have not to be dried.

Advantages / features:

•	Cooled mixing cylinder and side covers guarantee efficient process cooling
•	The mixing tools reach the entire inner surface
•	Shear teeth against bridge building or product agglomeration
•	Minimal residual product after discharge

Technische Daten:

Batch size:		500 to 10'000 liter (132 to 2642 US gal.)
Operating pressure:		inert gas blanketing, vacuum tight design is possible

Options:
Layout of a space-saving tower construction (dryer and cooler on top of each other), or as a separate vertical cooler (picture).

Filling Systems / Containers

Tandem Drum Filler - FHA
Designed for the filling of 200 liter (52.8 gal.) drums or pails.

For the filling of all medium to high viscous materials, especially suited for reactive systems.

Advantages / features:

•	Automatic switching from full to empty container
•	The filling time per drum is 3 to 8 minutes, depending on the viscosity and flowing property of the product to be filled
•	Accuracy about 300 grams (0.66 pounds)
•	Charged by mixer or buffer press
•	Follower plates with vacuum connections for holding the protection foil
•	2 operating boxes and a graphic operator’s display for editing up to 80 filling programs

Options:
Design is also available as single station
Mounting on 4 wheels for mobile use

Diverse

Steel- and Special Constructions
In-house manufacture of bigger units and mounting by the own qualified stuff. Work pieces can be treated in our own plant to pickle stainless steel.

Fitech AG owns the operation attest S1 for the Norm SIA 161/1. This includes the qualification for welding works.

Typical constructions
•	Bridges or parts of them
•	Supports for heavy loads
•	Poles
•	Supports for trusses and frames
•	Special parts for incineration plants (reactors, channels, etc.)
•	Any kinds of welding constructions in carbon and stainless steel.
