Model PPU/RU - Continuous Positive Pressurization Filtration Systems
PPU/RU equipment is designed to provide and maintain continuous positive pressurization with corrosive gas-free air in environments that require a controlled atmosphere. These are typically computer rooms, control rooms, motor control centers and electronic or electrical equipment in industrial activities susceptible to problematic emissions such as petrochemical, paper mills, foundries and laboratories.
These units can work by performing both pressurization and recirculation functions or only pressurization. When used in combined operation, up to 50% of its flow is used to maintain the positive pressure while the rest is used to recirculate the room air. The capacity of the equipment is 700 m3/h.
The most common contaminants that are filtered are: hydrogen sulfide, sulfur dioxide, nitrogen oxides, chlorine compounds, ammonia, etc. These machines are built in steel sheet coated with zinc, with a surface treatment consisting of degreasing and phosphating, passivation with Ecolo zirconium, and finally painted with epoxy paint and oven polymerized.
In these equipments the different filter media are loaded, according to the needs of each case, in PP12 modules. They also include G4 and F7 particle filters.
