Why The Cubo Solutions?

With SAIFOR’s CUBO solutions we create the containment defining thermal aisles, avoiding the mixture between the hot and cold air, this optimizes the datacenter functions and provides operational and energy savings.

Measure the datacenter energy, be efficient.

The energy consumption has to be controlled, that is why constant measurement should be taken that allow us checking the operational efficiency of the infrastructure and the equipments.

We can only control and improve the things that we can measure, that is why we have to check the equipments and infrastructure energy consumptions values constantly, comparing them with the one taken before, this will allow us to prove the efficiency and to be able to apply the necessary actions.

One way to optimize the consumption and have a perfect energy distribution is by using our intelligent PDUs with Sentry energy Management System.

Airflows control, security.

Zero Airflow solutions, control airflows, increase infrastructure efficiency and reduce the energy consumption inside the installation.

Applying the Zero Airflows solutions a increase of a 15%-30% can be obtained, increase the redundancy, reduce the CO2 emission, allow an increase of 5-10% Kw/rack of the energy in the rack (it is easy to prove, because when the charge energy increases in the rack, the PUE improves).

cubo-saifor-en-1-copiaIn hot and cold aisle a control of the airflows is provided avoiding air recirculation, improving the air intake on the top of the rack and improving the returning air to the CRAC.
At the racks level, the Zero Airflow system avoids air recirculation, minimizes hot spots, optimizes the fans use and improves the passive airflow.
In the raised floor, reduces the air loss, optimizes airflow, improves the airflows in the rack and minimizes the air obstructions.

These solutions combined with SAIFOR’s cooling solutions increase energy efficiency, due to a passive cooling management that avoid the mixing between the cold and hot air, isolate the unwanted flows that come from the equipment on the side, provide the right cooling of the equipment and create cooling with special ventilators.

Control the temperature, be quiet.

Increase the datacenter temperature helps reducing the energy consumption. To get this SAIFOR has designed an advanced cooling system, which includes EC variable speed fans.
With the HDC and MDC cooling systems the maximum cooling capacity between 36kw-17kw respectively.
Allows creating high density areas in the same row of racks.
Keep cooling stable.
Eliminate the hot spots.


Free cooling, more with less.

Get the maximum from the outside air, using SACS solutions for high density aisle.
Our HDC system (High Density Cooling) for aisles and racks allows reaching the highest efficiency level for high density datacenters.
HDC system allows water intakes between 6 ° and 20 °, it has been specifically designed for a high performance cooling with high temperatures water inlet, increasing the time of using free cooling, eliminating condensation and thereby maintaining compressors off for a longer period of time, this will provide greater energy savings.
Reduce CO2 emissions.
Redundancy at aisle level, allowing to turn of aunit if it is necessary for maintenance.
Modular and scalable application.


Light the datacenter, control de consumption.

Minimize 1-2% of the consumption using intelligent lighting systems inside the aisle.
SAIFOR solutions datacenter lighting systems, guarantee savings, security and technology. The lighting is fitted at the aisle level, several sensors are located to turn on the lights only when it is necessary and all the lighting systems are LED providing more efficiency.


Types of configurations


Hot AISLE containment system combined with aisle cool units.

SAIFOR recommends the use of hot aisle containment solutions for various reasons:

When the hot air becomes concentrated, air ΔT is increased and the cooling units are kept in the best operating zone.

The cold air expelled into the cold aisles can be used to reduce the overall temperature of the room.

The room itself acts as a “cold-air containment”.

More uniform distribution of cold air according to the hot spots in the room.

Possibility of higher temperature in the cold aisles so that chillers can work at higher temperatures, reducing CO2 emissions.

Ideal solution for installations with Free Cooling.


Cold aisle containment system with aisle cool units.

In this case, the Cool Units blow the cold air to the contained aisle, being the hot air dissipated to the room.

When the heat of the equipment in the room is dissipated, the ΔT is lowered, making it necessary to work with higher temperatures so as to achieve the best working conditions for the cooling units.

SAIFOR recommends implementing this when CUBO® active hot air containment.
Example: Data Centres with traditional cooling prepared for Medium Density, which need to apply High- Density solutions.

CUBO® Cold Air Containment 

Cold aisle containment system to optimise facilities with a traditional Plenum cooling system.

Cold aisle containment in datacenters that work with a under-floor cool system increase their efficiency through containment of the cold-air aisles.

By closing off the cold aisles and thus preventing the mixture of hot and cold air, more constant and stable temperatures are achieved in the upper parts of the racks.

These improvements, in conjunction with the optimisation and control of the air flows, enable the room’s operating temperature to be increased with the resulting energy saving.

This system allows sensors, detectors, alarms or extinction system inside the aisle. Available for different aisle widths. Adaptable to be used in retrofitting projects.

Emergency Roof Panels Opening System

This system is completely automatic; it is activated in case of incidences inside the datacenter. In case of emergency the panels open automatically allowing the pass of the water or gas inside the containment. This solution it is not necessary to modify the sprinklers extinction systems inside the datacenter.

This system incorporates an electromagnetic lock that allows connecting directly with the infrastructure BMS system, activating automatically when there is an incidence. The central section of this roof system has a deflection design that opens the panels 105° allowing the water and gas to get into the containment, making easier to clean and maintenance the panels, because when they are open there is a total access to the roof. The roof also includes a longitudinal and transverse cable duct to manage the cabling between aisles.

Soluciones Retrofit

The retrofit solutions try to reduce the energy consumed by cooling, raising the temperature in the room, and at same time to prolong the useful life of the equipments together with a reduction of maintenance costs. In order to get this, the main solution is the physical separation of the hot and cold air.

SAIFOR offers a highly modular system, with a high degree of customization that allows closing the hot and cold aisles, even with products that are not from SAIFOR, and without interrupting the regular performance of the datacenter.


Knowing that every retrofitting project is unique, SAIFOR has a highly qualified team with a wide experience in custom-made retrofitting to get the maximum efficient of the existing installation, foreseen a future expansion and adjust the budget to the maximum.

One of the advantages of SAIFOR as a manufacturer with engineering, a production plant and its own product, is the guarantee to a good performance, because we ensure the perfect integration of our solutions, combined with CUBO solutions, our highly precise cooling units to those facilities where high density is required, and also the cable management solutions and power cabling.
