Room feed with plenum return
This cooling system addresses the requirement to separate hot air from the room by using a vertical “chimney” on the top cover of the cabinet to exhaust hot air directly into the hot space in the double ceiling.
One of the potential disadvantages of cold aisle containments with floor-based cooling with exhaust to the hall is that the hot air is routed to the surrounding area behind the cabinets. In general, this should not be an issue, if it was taken into account in the design of the data center. However, in some data centers with a high concentration of installed technologies, it may be desirable to completely separate the hot and cold air flow.
CONTEG-Kit for cooling based on air supply from the hall and exhaust to ceiling (HPR) is a solution where hot air is not kept in the hall but is exhausted to the ceiling/double ceiling. A rear deflector located at the bottom of the cabinet helps to optimize the flow of hot air into the exhaust pipe. The large volume and cross section ensures that the exhaust pipe is able to take in a large amount of air at a relatively low velocity.
In some data centers with a high concentration of installed technologies, it may be desirable to completely separate the hot and cold air supply.
After the cold air is drawn in through the front door, the hot air is then exhausted to the ceiling/double ceiling above the cabinets, relying on the natural stratification of the hot air. Server room air conditioning units (CRACs) draw hot air from the ceiling, cool it and dispatch it back into the room, closing the loop. This arrangement allows a very large volume of hot air to be cooled with high efficiency. A study by Intel, which pioneered this solution, proves that up to 30 kW per cabinet can be cooled with this concept.

| Recommended configuration of cooling with air supply from the hall and exhaust to the ceiling |
Cold air enters the cabinet through the expanded metal front door. The separation frame and blanking panels prevent cold air from mixing with hot air and optimize airflow. The hot air in the rear of the cabinet is directed by the rear air deflector to the exhaust pipe, which is located on the top cover of the cabinet. The rear metal door prevents hot air from getting back into the room and mixing with the cold.

| Recommended cooling systems | Recommended cooling systems for chimney solutions require central cooling systems with supply of conditioned air to the space under the double floor, or directly to the data room, or installation of lateral cooling units. We have been an official partner of a leading global manufacturer of cooling solutions since 2008. This partnership enables us to offer sophisticated central cooling systems. Do not hesitate to contact us, we will be happy to assist you whether your project requires a simple cooling method or a massive central cooling capacity. |
PREMIUM Server RF1 is a new and unrivaled cabinet of the Premium series designed for the most demanding customers and modern data centers.
New types of rails with U-position markings are very easy to fix, offering an extraordinary degree of variability of the internal layout. An 86% perforated door can be opened up to an angle of 190°.
The RF1 cabinet is compatible with all CONTEG cooling, airflow optimization, and flexible cable management systems, as well as with many additional systems, such as access systems, PDUs, smart power, and fire extinguishing systems.
The portfolio of power distribution units (PDU) that ensure power distribution in high power density IT environments includes 3 types - controlled PDUs enabling control of individual sockets or their groups remotely via a data network, monitored PDUs enabling remote monitoring of the current drawn from the power supply panel via Ethernet /IP, and basic PDUs with no additional features.
The RAMOS monitoring system is used to monitor the internal and external environmental conditions (temperature, humidity, water leakage, smoke, etc.) in large data centers, server rooms or individual cabinets. The system is ready to integrate and monitor other devices, such as smart power supply panels (PDUs), uninterruptible power supplies (UPS), cooling units, etc. The system supports remote control. RAMOS includes 4 types of main monitoring units with differentiated sets of functions. The units support a different number of sensor and offer different number of inputs and outputs. All main monitoring units have a built-in web server for basic settings and can also be integrated into the CONTEG Pro Server application, which allows for central management, monitoring of the environment, and access using RAMOS hardware. Information can be transmitted over the following protocols: HTML, XML, SNMP, SMTP.
