RVP-P-EX flow regulators
Flow regulators are used for automatic regulation of the stream flowing through the air ventilation ducts both in the supply and exhaust part of the system. By changing the air consumption, they enable to create the individual climate for each of the rooms in the building, considering the occurrence of non-uniform loads in those rooms, depending on the number of people present in the room, as well as on variable external factors such as: heat gains through non-transparent and transparent partitions as a result of sun exposure.
Relative to the work environment, the regulators RVP-P-Ex may be executed in two versions. In the standard explosion-proof version, the regulator is designed for the adjustment of clean stream of filtered air, whereas in special version also with application for transporting the contaminated air or slightly aggressive air (pursuant to Corrosive Environment Classification in compliance with ISO 12944 max. class C3).
The devices RVP-P-Ex provide the high safety level and are designed to be used in the places, in which the explosive atmospheres are likely to occur, caused by gases, vapours, mist or air-dust mixtures.
The regulators RVP-P-Ex are designed in compliance with the directive ATEX 94/9/EC as the devices of group II category 2 and designed for using in the explosion-hazard zones 1,2,21 and 22.
The producer’s ATEX certificate is available for the electric components.
