Filtre a tambour sans matieres consommables HTF
Applications:
Continuous cleaning of contaminated coolants as they occur when using machine tools.
Recommended for use for high flow rates; the flow rate is increased three to four times with the same filter area and low filter medium consumption compared with a gravity filter.
Function:
The contaminated coolant flows from the machine tool via an inlet distributor into the contaminant chamber of the filter. Arranged within the contaminant chamber is a filter drum, covered with a seamless stainless steel filter fabric. As a result of the pressure difference Ap produced between the contaminant and inner space of the filter drum by means of a vacuum suction pump, the medium is sucked into the inner space of the filter drum, whereby chip and dirt particles are filtered out through the filter fabric. The filter cake forming on the filter fabric surface produces an increasing partial vacuum in the inner space. When a preset value is reached, regeneration is initiated by means of a contact pressure gauge. The filter drum is set in rotation and the filter cake is lifted off the filter drum by means of a stationary scraper and removed via scraper plates connected to endless chains and driven by a geared motor; the scraper plates pick up the dirt on the tank bottom and transport it via an incline to the discharge edge. As the discharge edge is located above the liquid level, the contaminant discharge is simultaneously dewatered to enable easy disposal. Arranged in the drum inner space is a stationary nozzle assembly, which is supplied externally with clean medium. The rotation of the filter drum causes the filter fabric to be flushed free over the entire surface from the inside to the outside; this prevents clogging of the filter fabric.

Hydrozyklon ZY
Applications;
Hydrocyclone coolant cleaning plants operate wherever heavy dirt particles have to be separated from low viscosity liquids. For example, at machine tools (particularly grinding machines)), machining centres, transfer lines or part cleaning plants.
Function:
The liquid to be cleaned flows with a pressure of 2.2 bar via the inlet coil into the cylinder part of the hydrocyclone. The tangential arrangement of the inlet and high flow velocity gives rise to the formation of a primary eddy that rotates at high speed which increases continuously with a reducing diameter of the cone housing. As a result of the high rotational speed, considerable centrifugal forces act on the dirt particles which are forced against the walls of the cyclone and discharged with a small quantity of water through the underflow nozzle. As a result of the diminished cross-section in the cone housing, the flow resistance increases. This reverses the direction of rotation of the primary eddy in the lower area of the cyclone. The resulting secondary eddy moves - rotating in the same direction - upwards through the immersion tube into the clean water chamber. Within the secondary eddy is an air core, which cools the coolant and therefore has a rot inhibiting effect.

Centrifugal separator Wear-resistant plastic housing Easy replaceable parts

Oilskimmer
Applications:
For cleaning, e.g.: Coolants
Cleaning plants/washing baths Galvanising plants Cutting machines Waste disposal plants Seepage pits/sewage treatment plants
Function:
High demands are placed on coolants as well as other liquids with regard to their useful life, production quality, industrial hygiene and disposal. Foreign oils and suspended contaminants stop the oxygen supply and the medium "turns". This provides ideal breeding grounds for bacteria, fungus and yeasts, which cause irritation of the skin, allergies and mucus formation; the medium must be changed. For this reason, cleaning with oil skimmers is essential, not least for hygiene and economic reasons.
Advantages:
Increases useful life of employed media Reduces disposal costs Less personnel absence due
to skin disorders Easy to use Compact design High output
