Water separator WA 4i MultiQube

Water separator WA 4i for combination with MultiQube insulation layer dryers

The new WA 4i is provided with an integrated micro filter system with low-maintenance magnetic lock filter compartment to take in micro filter cartridges with a threefold filter element.

This makes the WA 4i a versatile integral solution with all pre-HEPA filter stages in only one device.

Advantage: improved flow-optimized filter technology, quicker setup, decreased material and space requirements – no separate additional micro filter housings required.

With respect to insulation drying of surfaces sized up to 40 m², no other model is quite fit to hold a candle to this separator, for despite its ultra-compact dimensions the WA 4i comes fully equipped with numerous practice-oriented detailed solutions, such as a construction yet easier to maintain, TTKwic quick couplings, cable holder, residual water drainage and much more.

The water separator weighing only six kilogrammes is optimally geared to the combined use with Trotec MultiQube modules like the VE 4 MultiQube and at the same time 100 % downwardly compatible to previous models. 

WA 4i micro filter cartridges with threefold filter element

Maintenance-friendly integral solution with a quick and easy exchange of only one cartridge.

It can only be inserted into the WA 4i's filter compartment in the direction of air flow, which provides even more security during application.

This way one can not only realize especially space-saving installations, the operation, control and reading of process information can also be performed much more effectively!

With a filter surface of 0.16 m² and a nominal air flow rate of 50 m³ per filter element, the WA 4i micro filter cartridge is optimally adjusted to the maximum air flow rate of the vacuum turbine of the VE 4 MultiQube compressor. The filter cartridge with a minimum flow resistance according to DIN EN 779 has filter class F8 and thus meets the requirements of a pre-filter for HEPA filtration.

– the smart quick coupling for one single central water discharge

TTKwic – the smart quick coupling for one single central water discharge

For an effective remediation of water damage condenser dryers are usually used in continuous operation with an integrated condensate pump, which so far for each individual drying unit entailed an elaborate laying of water discharge hoses over long distances from the dehumidifier to an appropriate water drain.

Despite the ingenious construction the application of the TTKwic is extremely user-friendly: Connect the hose and you’re done!

Save time and material for complicated multiple installations of condensate discharge hoses to far-off water drains and simultaneously ensure an effective and reliable permanent drying – quick, easy, clean and reliable thanks to TTKwic!

TTKwic puts an end to this:

Every WA 4i MultiQube as standard comes with two integrated TTKwic quick couplings, where condensate discharge hoses of the used dehumidifiers can be connected conveniently and expeditiously. The entire water drainage is then taking place centrally via the discharge hose of the water separator.

TTKwic: The smart quick coupling for the connection of dehumidifiers with condensate pump. One single central water discharge for all drying devices!

The TTKwic quick coupling is an especially developed pressure coupling with special valve and optimally geared to the combined use with Trotec condensate pump kits.

For water intake the valve opens exclusively with pressure load on the pump side and by means of an integrated barrier simultaneously prevents a decrease of performance of the low-pressure stream permanently and reliably.

TTKwic – Trotec exclusive!
