“We want to prevent contamination from oil leaks” DMNβ

We want to prevent contamination from oil leaks

A pharmaceuticals manufacturer, O Corporation, told us, “Previously, a clean room centrifuge with an open and close style casing had oil transmission as standard, but since there was a risk of oil leaks which cause contamination, we want to prevent this contamination.” So we proposed our electrically open and close casing model.

Not only the casing but the crystal scraper also did not have an oil transmission and was electrically driven as standard.

In addition, with the objective of improving cleanability that is considered important in pharmaceuticals manufacturing, we also proposed and supplied a centrifuge equipped with a casing panel, casing open and close mechanism, and a liftable basket.

As a result of using our centrifuge, there is no risk of oil leaks inside the clean room, and as the efficiency of cleaning the machine interior has increased, this has led to a reduction in risk of contamination.

Key Points – customized specification focused on cleanability

Electrically driven open and close type

・By employing a grease type, contamination from oil leaks can be reduced.

・As there is no oil pressure unit or hose, the machine structure is simple.

・This enables stable operation. Due to the operation using the local control panel, operability is increased (Enapack, etc., operates as a unit).

In contrast to oil-transmission, it receives high praise for smooth operation and the quality of the grease lubrication type handling.

In addition, it includes our original technology, and with options not found in other companies’ products, it is a popular specification.

Casing panel

As the casing is rounded without corners, there are no corners where the crystals can become clogged.

This prevents mixing of foreign matter or contamination when switching products.


Casing open and close mechanism

By using an open and close style casing, when the basket is open, the centrifuge casing interior, the whole basket and any attached equipment can be cleaned thoroughly. Due to this, the centrifugal can be sufficiently cleaned.


Liftable basket

By raising the basket, the casing interior and basket bottom can be easily cleaned, which lightens the workload of the machine operator and contributes to increased product quality.
