Quiet pressurization system: If the utility room is small and located near living quarters, reducing noise and space requirements becomes a priority. In this response, we see a system design that is specifically aimed at minimizing noise and size, especially in apartment buildings.

What are the components of a pressurization system?
A pressurization system typically consists of the following components:
- Free-surface water reservoir (initial collection basin)
- Pressurization Unit
- Pressurized storage system
- Electrical Control Panel
- Electrical and Plumbing Supplies
This “block-based” layout helps illustrate where space constraints and noise levels are typically concentrated.
Why are noise and clutter often a problem in apartment buildings?
In many cases, the water storage tank and the pressurization unit are the components that take up the most space. Furthermore, the pressurization unit is the only component that generates noise during operation.
These systems are often installed in spaces that are, in some way, adjacent to the building’s living areas. This creates the risk of generating noise in the apartments that is unwelcome to the residents.
Quiet Pressurization System: The Design That Reduces Noise and Space Requirements
If the goal is a system design that minimizes noise and size, there is a specific solution: use submersible electric pumps mounted directly inside the free-surface water tank.
In practice, instead of having an external pressurization unit (with motors “outside the tank”), the pumping function is moved inside the water tank. This is the key point that ties the two objectives together: less space required and less perceived noise.
How Spaces Change: What Is Removed and What Is Simplified
Using a system with submersible electric pumps results in an immediate reduction in the space required because:
- The external pressurization unit is no longer present; it has been replaced by submersible electric pumps installed directly in the water tank.
- As a result, the utility room is more “open” and less constrained by the space taken up by the outdoor unit.
This feature is particularly useful when equipment rooms are small, with limited access to components and cramped spaces for installation and maintenance.
Pressure Storage: Why You Don’t Need a “Large” External Tank
With this system, a large external pressure tank is no longer necessary. The text highlights that submersible pumps are capable of cooling down very quickly; therefore, two 20-liter pressure tanks are sufficient to achieve cycle times (on/off) compatible with the system’s proper operation.
In other words, the pressurized storage system is “scaled down” in a manner consistent with the operation of the submersible pumps, thereby helping once again to minimize the overall footprint.
Modular water reservoir: multiple tanks in parallel to manage flow
Another practical consideration concerns the water reserve itself: it can be easily set up by connecting multiple tanks in parallel (using pipes of the appropriate diameter).
This allows you to:
- achieve the storage volume specified in the calculation;
- Avoid problems related to the size of the openings needed to access the utility room.
This “modular” design is useful when access to the utility room is difficult and a single large tank might be hard to bring in and position.
Why is the submersible pump system quieter?
The use of submersible pumps makes the system very quiet, because it eliminates the following problems:
- noise generated by the operation of external engines;
- the transmission of vibrations along the pipes.
This is an important point: it’s not just a matter of “making less noise in the equipment room,” but of reducing the likelihood that vibrations and noise will reach residential areas, precisely because the way the pump is installed relative to the water reservoir has changed.
Inverters: Performance Tailored to Needs and Operational Benefits
Finally, these systems (like all others) can be controlled via an inverter. The goal is to align the machines’ performance with the plant’s requirements.
The text links this approach to two practical effects:
- significant energy savings;
- a reduction in maintenance requirements.
In a condominium setting, the logic is clear: if service levels are based on actual demand, the system operates in a way that is more consistent with actual usage.
Conclusion: A Choice Focused on Comfort and Space
If you want a quiet and space-saving pressurization system, the setup using submersible electric pumps installed in a free-surface water tank is a tailored solution: it reduces the footprint (by eliminating the external unit and a large pressurized tank) and minimizes noise, avoiding the noise of external motors and vibrations transmitted through the pipes.
