First class quality

The centrifuges, we deliver, go through a complete- or service overhaul, from our side. The overhauls are being carried out and supervised by experienced experts. Before delivery the centrifuges are undergone extensive tests on our own engine test bed. On request the centrifuges are delivered without any overhaul, „as is“.

General overhaul in 12 steps:
The general overhaul covers, in extend to the work steps of service overhaul, a complete disassembly of the machines in order to measure and test more precisely.

Service overhaul in 7 steps:
In the context of service overhaul our specialists test the most important machine parts for wear and tear. Bearings and seals are being replaced.

Savings up to 70%

On purchase of a second hand, but general overhauled centrifuge with warranty of Centrimax you can save up to 70% opposing the cost of a new machine.

Take advantage of this benefit!

Centrimax warranty

Before delivery, we undergo our general-overhauled centrifuges a comprehensive function test on our engine test bed. Only after successful passing all tests, we deliver our machines with a 7 month warranty aboard or 13 month warranty within Germany.

Remanufacturing (factory rebuilt)

Character of a new machine throughout general overhaul.
In order to receive a durable, dependable and long-life centrifuge, you should buy second hand centrifuges from centrifuge specialists, only.

PLC-based control system

In general, the complete- or service-overhauled centrifuges are applied a new process- and customer -specific configured PLC control (Siemens S7, OP with visualization).
The Controls are optimized on the respective centrifuge. Depending on the request of the customer the machine, the automated valve, the applied pumps and the loop system, can be controlled.
The graphical operator panel enables a user friendly operation via function keys (on customer request also with Touch panel).
Data exchange with other controls (for example central control) are realized by potential free contacts, Ethernet or a professional bus on customer request. Thus it is secured that the centrifuges are integrated into processes without any problems. Every control is tested on our engine test bed, before delivery by our experts to setup fast on-the-spot without any problems.
More about new PLC control

Own test bench

Each general- or service overhauled centrifuge is subjected to a comprehensive test run on our own test bench before delivery.
Thus the function as well as the vibration values are tested and documented. This ensures, that every delivered centrifuge works correctly and the vibration values are in the given range.

Inhouse test laboratory

Various methods are known and there are relevant past experiences regarding the respective product, so no attempts have to be performed, in order to evaluate whether the desired goal can be reached via use of a centrifuge.

But there are various special procedures, where past attempts according to the suitability of centrifuges is needed or at least useful.
In this case we can perform experiments via a small amount of material with our laboratory-centrifuges.
Often it is possible to assume reliable whether a centrifuge is suitable or not, afterwards.
In case that further 1:1 experiments are needed on the spot, we can mostly supply smaller testing machines for the on the spot for a fee.

Quick delivery

Since Centrimax constantly has over 700 centrifuges in stock, a quick delivery can be realized.

Commissioning/process integration

The general- or service-overhauled centrifuges, delivered by us, naturally are put into operation by our experts (if the customer desires).

Throughout our modern centrifuges-control panels (normally Siemens S7) the delivered centrifuges can be implemented into the production process without any problems.
The therefore needed data exchange with a superior (central-) control panel, is realized, depending on the customers desires, via potential free contacts (digital input/output), Ethernet or a professional bus connection.

In extend to the implementation an instruction or schooling of the staff occurs.
