You can find all necessary information in our catalogue. In case of any questions, please feel free to contact our team.

Thanks to the vacuum technology applied the dryer allows for quicker drying and cooling of the membranes before the analysis.

Working time is around 7 minutes.

Additional advantage is limited influence of the contamination coming from the outside.

The membrane is transported to the dryer (and then to the balance or microscope) in a Petri dish.

Basic technical parameters:

external dimensions: ca.400 x 400 x 600 mm

weight: ca. 30 kg

number of membranes per batch: 1

This is a solution for big elements - chamber designed for elements up to 500 kg and up to 2.000 mm.

Comfortable system for rinsing and flushing of the elements. Suitable manipulator facilitates easier and handling and loaing/unloading of the elements.

The system works in accordance with VDA19 and ISO 16232.

Two working stations - two working chambers connected in one testing system. Rinsing, flushing,  immersion and ultrasound.

This machine replaces two separate systems for technical cleanliness analyses.

The system is designed for elements up to 70 cm and 15 kg, and up to 25 cm and 3 kg in the chamber with ultrasound.

The system works with accordance with VDA19 and ISO 16232.

RiuS Single cabinet of second generation guarantees state of the art technology in the range of technical cleanliness analyses.

The chamber was designed according to regulations from VDA 19.1, chapter 11 concerning safety and environmental protection.

The machine is dedicted for testing with rinsing method. Inside there is a spraing head with a nozzle and hose and a stand for hanging of the head.

The chamber is closed with double sliding door protecting the working area from contamination coming from outside during the machine's standstill.

Bottom of the chamber comprises of basin made of polished stainless steel with dimensions: 1.200 x 800 mm.

MAximum weights of the tested elements can be up to 100 kg, evenly distributed.

The system works with accordance to VDA 19 and ISO 16232.

Interior of the chamber is characterized by perfectly smooth surface and flawless construction.

The machine allows for testing with flushing method and immersion with ultrasound.

ACM18 is dedicted for testing of small and medium elements (up to 50 cm). Testing element can be up to 15 kg.

Interior of the chamber comprises of basin made of polished stainless steel with dimensions of 600 x 750 mm. Inside the chamber there is a spraying head with nozzle and a stand for hanging the head.

The machine is equipped with three stage membrane holder suitable for membrane with diameter 47 mm.

The machine has got temperature sensors and level sensor. These parameters are constantly monitored by a separate security system. This causes that the chamber can be classified as EX Zone 2.

The system works with accordance to VDA19 and ISO 16232.

Process of degreasing of the surface affects directly the whole range of surface finishing types (painting, metalisation, phosphatising, etc.). Below you can find products for quick and accurate testing of the surface tension of the parts during the processes of cleaning and degreasing.

In order to determine the level of surface tension, the parts are randomly tested by checking grease level. This method is based on the measuring of the surface tension, which means measuring surface energy of the material by checking contact angles with test inks. The values are expressed in mN/m (miliNewton per meter). For example oiled surface oscilates around 25 mN/m and washed surfaces are in the range from 38 mN/m up to 70mN/m - depending on the cleaning effectiveness. Testing is peformed by applying test inks with defined value (in mN/m) on the surface. The bottle with brush or test pen filled with the testing ink can be used. If test ink spreads, the surface tension of the applied ink is lower than that of the surface. If the stroke remains unchanged during the observation period, the value of the surface tension has been reached exactly or is slightly higher.

We can offer set of test inks in the form of test pens and bottles (10, 100 and 250 ml) in the range from 18 to 72 mN/m.
