"RTU-90(15 T) 600 V, 70A, 3P" is a specification or description for an electrical device or component. I can try to break down what each of these terms and values might mean, but I should note that without additional context, my interpretation is just a general explanation:
RTU-90(15 T):
RTU: Typically stands for "Remote Terminal Unit." RTUs are commonly used in industrial control systems (ICS) like SCADA (Supervisory Control and Data Acquisition) for the purpose of data collection and control. They communicate with a master device and can both send data to it and receive commands from it.
15 T: This notation is not standard across all contexts. It could refer to a model, series, type, or some specific characteristic of the RTU.
600 V:
This likely refers to the voltage rating of the unit. In this case, the RTU can operate safely at a voltage of 600 volts. Remember, always ensure that you do not exceed rated voltage levels to prevent potential damage or unsafe conditions.
70A:
This is likely the current rating of the device. It suggests that the unit can handle a continuous current of up to 70 amperes without any issues. Again, it's crucial to operate devices within their specified current ratings.
3P:
This stands for "3 Phase." In electrical engineering and power distribution, many systems use three-phase power. A three-phase system is a common method of alternating current power generation, transmission, and distribution. Devices designed for 3P are meant to operate on such systems.
How it works:
If this is indeed an RTU (Remote Terminal Unit) designed for a three-phase 600V system with a 70A current rating:
The RTU would be installed in a suitable location where it needs to collect data or control certain processes or equipment.
It would be connected to sensors or other devices that feed it data about system conditions, like temperatures, pressures, flow rates, etc. This data can be relayed to a central control system.
The RTU can also receive commands from the central system to control connected equipment, such as opening or closing valves, starting or stopping pumps, adjusting set points, etc.
Given its voltage and current ratings, it would be essential to ensure that any connections, either for power or control, comply with the rated specifications to ensure safe and reliable operation.
If the "RTU-90(15 T) 600 V, 70A, 3P" is indeed a Remote Terminal Unit or a similar large electrical device, its installation and presence could certainly affect the interior of a given space. Here are ways it might influence and the design considerations that should be kept in mind:
Impact on Interior Space:
Physical Size: The RTU itself will occupy space. Depending on its size, it could potentially take up significant floor or wall space.
Aesthetics: Large electrical equipment might not be aesthetically pleasing. Depending on where it's installed, it could be a visual distraction.
Noise: Electrical equipment, especially when containing relays, fans, or other moving parts, can generate noise during operation.
Heat: Electrical devices, especially those with high current ratings, can produce heat. This might affect the ambient temperature of the room.
Electromagnetic Interference (EMI): Large electrical equipment can produce EMI, which could interfere with sensitive electronics or communication equipment in the vicinity.
Design Considerations:
Location: Consider where the RTU will be placed. Ideally, it should be in a location that's easily accessible for maintenance but not obtrusive for the primary functions of the space.
Ventilation: If the RTU produces heat, the room or enclosure where it's placed needs adequate ventilation. This ensures the device remains within its operating temperature range and the room doesn't become uncomfortably warm.
Noise Reduction: If noise is a concern, consider using soundproofing techniques or materials to dampen any noise generated by the RTU.
Safety: Ensure that the area around the RTU is safe. This includes providing enough clearance for operations and maintenance, ensuring no tripping hazards, and maybe even installing barriers if needed.
Electrical Infrastructure: Given the high voltage and current ratings, the electrical infrastructure (like wiring, breakers, grounding) needs to be appropriately rated. Ensure that installation adheres to local electrical codes and standards.
EMI Mitigation: If EMI could be an issue, consider using shielding or placing the RTU away from sensitive equipment.
Aesthetic Integration: If the RTU needs to be in a space where aesthetics are a concern, consider ways to integrate it into the room's design. This could involve using enclosures, panels, or even decorative elements to mask or complement the device's appearance.
Accessibility: Always ensure that there's adequate space around the RTU for technicians or engineers to access it for maintenance, repairs, or updates.
Future Expansion: If there's a possibility of future upgrades or additions to the system, design the space to accommodate such expansions without major renovations.

RTU typically means Roof Top Unit.
It's type of HVAC system that contains all the components needed to provide conditioned air in one unit. There are many types of Rooftop Units (RTU's) including 100% Outside Air Units (DOAS), Gas/Electric, Heat Pump, Straight Cooling, VAV or constant volume.

Now we're getting somewhere!
Yes, in the context of HVAC (Heating, Ventilation, and Air Conditioning), "RTU" typically stands for "Rooftop Unit." An RTU is a type of HVAC system that's installed on the roof of buildings. They're common for commercial buildings where interior space is at a premium, and it's convenient to place HVAC equipment outdoors.
Given this context, the design considerations and impact on interior space are different from a Remote Terminal Unit:
Impact on Interior Space:
No Occupied Space: One of the primary benefits of an RTU is that it doesn't occupy valuable interior space since it's mounted on the roof.
Ductwork: While the unit itself is outside, the ductwork for an RTU runs through the building. This can affect space, especially ceiling areas.
Noise: Even though the RTU is on the roof, some noise might still be transmitted into the building. However, being outside does help in reducing the noise level perceived inside.
Vibration: RTUs can produce vibrations that may be transmitted into the building structure.
Design Considerations:
Roof Load & Structural Support: RTUs are heavy, so the building's roof must be structurally capable of supporting the added weight.
Access: The RTU will require periodic maintenance. Ensure that there's safe and convenient access to the roof.
Weather Protection: Being on the roof, RTUs are exposed to elements like rain, snow, and direct sunlight. They're designed for this, but considerations for extended durability, such as protective coatings or shades, might be beneficial in harsh climates.
Ductwork Integration: Ductwork should be efficiently routed to serve the building's interior spaces while minimizing energy losses.
Noise and Vibration Mitigation: It might be necessary to use noise dampening solutions or vibration isolators to prevent sound or vibrations from disturbing the building's occupants.
Energy Efficiency: Select an RTU with a good energy efficiency rating to reduce operating costs. Consider features like variable-speed fans and high-efficiency compressors.
Controls & Thermostats: Ensure that the RTU can be easily controlled from inside the building, either with traditional thermostats or modern building management systems.
Condensate Drainage: Water that condenses on the cooling coils needs to be drained away. Proper drainage systems should be in place, and they should be regularly checked for clogs or blockages.

Impact on Interior Space:
1. No Occupied Space: One of the primary benefits of an RTU is that it doesn't occupy valuable interior space since it's mounted on the roof.
2. Ductwork: While the unit itself is outside, the ductwork for an RTU runs through the building. This can affect space, especially ceiling areas.
Part of the ductwork can run outside the building. You’ll need to insulate it.
3. Noise: Even though the RTU is on the roof, some noise might still be transmitted into the building. However, being outside does help in reducing the noise level perceived inside.
See response to item #4
4. Vibration: RTUs can produce vibrations that may be transmitted into the building structure.
It’s a good idea to set a RTU on a vibro-isolation curb that is set on a concrete slab.
Design Considerations:
1. Roof Load & Structural Support: RTUs are heavy, so the building's roof must be structurally capable of supporting the added weight.
Yup.
2. Access: The RTU will require periodic maintenance. Ensure that there's safe and convenient access to the roof.
Yup.
3. Weather Protection: Being on the roof, RTUs are exposed to elements like rain, snow, and direct sunlight. They're designed for this, but considerations for extended durability, such as protective coatings or shades, might be beneficial in harsh climates.
Not really. If the climate is that harsh then RTU’s typically won’t work.
4. Ductwork Integration: Ductwork should be efficiently routed to serve the building's interior spaces while minimizing energy losses.
That applies to all mechanical systems.
5. Noise and Vibration Mitigation: It might be necessary to use noise dampening solutions or vibration isolators to prevent sound or vibrations from disturbing the building's occupants.
Don’t forget a concrete pad for the RTU to sit on.
6. Energy Efficiency: Select an RTU with a good energy efficiency rating to reduce operating costs. Consider features like variable-speed fans and high-efficiency compressors.
They are not as energy efficient as other systems.
7. Controls & Thermostats: Ensure that the RTU can be easily controlled from inside the building, either with traditional thermostats or modern building management systems.
You will need multiple units to have be able to individual areas of a building. Most RTU's can only handle 2-3 zones of different temps.
8. Condensate Drainage: Water that condenses on the cooling coils needs to be drained away. Proper drainage systems should be in place, and they should be regularly checked for clogs or blockages.
Most RTU systems have internal drainage systems and external hose bibs for required maintenance. It’s important to make sure the RTU isn’t creating areas that can trap water on the roof though.
9. Screening: RTU’s are big and ugly. Combine that with the curb they sit on and it’s very easy for them to be around 7’ tall. Make sure you design some type of physical screening to block the view of the unit.
