Low-pressure drying employing water separators to protect the vacuum turbine against water and coarse particles for years have been the state of the art in the drying sector.

Qualified specialist companies nowadays mostly only use the hitherto deployed standard procedure of excess pressure drying in unoccupied areas.

A comparison of both procedures as well as further information have been compiled for you in the "practical process information".

Due to the sensitization to allergens, carcinogenic microfibres, dust, asbestos, mites and the entire mould and bacteria issue, which has increased by a breathtaking pace over the years, the low-pressure procedure is not only preferable, but in some cases absolutely necessary, e.g. when mould has formed or mineral wool was used as insulating material.

Because during restoration work high concentrations of hazardous fine particulates, microfibres from the mineral fibre insulation as well as mould spores and bacteria from the insulation layer are inevitably released.

Only when using fine particulate air filters of the corresponding class they can reliably be filtered and their exposure can be prevented!

A precisely attuned filter system separates particles sized up to 0.3 micrometres to 99.97 % and ensures optimum purification of the process air before it is fed back to the air in the room or outdoors.

Water separator, micro and HEPA filters are perfectly well-matched special constructions designed by specialised engineering consultants and regarding filter surface and nominal performance especially geared for a maximum air flow rate of the vacuum turbine of the MultiQube insulation dryer units.

Therefore, all Trotec filters come with a manufacturer approval for the use of vacuum turbines with pressure differences of more than 250 mbar!

But the MultiQube multi-stage filter system
can accomplish even more...

With an uncompromising eye on the practical benefits for users, all modules are constantly advanced and complemented by performance-improving innovations.

Hence, the new WA 4i filter cartridge provides hardly any resistance to the air flow and the new HEPAControl function avoids a reduction of the drying air flow caused by contaminated HEPA filter elements.

The main idea of our modular design philosophy is that in line with demand you can determine all required devices for your specific task and have the respectively ideal overall system at your disposal for all combinations.

This claim cannot be realized with combination devices which have several components already integrated invariably. Furthermore, devices with complete fixed installations are usually larger, heavier and more difficult to handle, plus all elements will be in use even if only few are needed.

Dehumidifier in the compressor housing?

HEPA filter in the water separator?

These solutions not only increase the costs for acquisition, but also for maintenance and cleaning.

With the modular system you are set for any task yet to come...

With the Trotec modular solution you can specifically combine only those components needed for the respective drying application.

If all you need is a compressor, then a compressor is what you will be using.

Inhabited surroundings?

No problem, just install silencers.

Low-pressure drying?

Additionally combine water separator and micro filter.

Hygiene-sensitive areas, contamination hazard?

Add a HEPA filter to the drying installation.

Extremely accelerated low-pressure drying?

Install drying control unit DA 4 MultiQube.

The advantage is that all modules are exceedingly well-matched and can yet be combined equally at random or used individually.

The system thus unites high economic efficiency and simple handling with the greatest possible flexibility!
