IT Racks & Cooling

APC Netshelter Racks

APC Netshelter SX
The APC NetShelter SX is the next generation rack enclosure solution influenced by 10 years of customer feedback and addresses current IT market trends for high-density server and networking applications. With a strong focus on cooling, power distribution, cable management and environmental monitoring, the NetShelter SX provides a reliable rack-mounting environment for mission-critical equipment.

APC Netshelter VL - Cost-effective enclosure solution in any IT environment.
The APC NetShelter VL is the enclosure you have become familiar with from APC but now with basic functionality and features provided as a cost-effective solution. The NetShelter VL maintains a strong focus on cooling, power distribution, and cable management to provide a reliable rack-mounting environment for mission-critical equipment but with optional features such as side panels, casters, and rear cable channel that reduces the cost of the base enclosure.

APC Speciality Enclosure
Specialty enclosures ensure reliable operation of your rack mount IT equipment in unique environments. Wall mount enclosures are designed for small hub and LAN applications in wiring closets and server rooms with floor space constraints. Seismic enclosures are heavy duty enclosures that can be deployed in Zone 4 regions that require the safety and ruggedness of an NEBS rated enclosure. Office Enclosures are specialized enclosures with integrated cooling, noise dampening, and power distribution for server and network applications in office environments.

Data Centre Cooling

In a communications room, or any enclosed area where a significant level of electronic equipment is located, an efficient and reliable air conditioning system is critical to maintaining a stable environment. There are several options to choose from when it comes to selecting the right cooling solution, Source UPS work with Liebert and APC, two of the world leading manufactures of precision cooling for computer rooms and data centres to to offer a portfolio of products for all applications.
 
Hot Aisle Containment Cooling Solutions
Most IT equipment, particularly rack mounted devices, breath cold air in the front and exhaust hot air from the rear. Hot aisle/cold aisle aligns the cabinets in rows around this concept, with the server exhausts of each row back to back, facing one another, becoming the hot aisle.  The hot aisle air is immediately captured and contained so server exhaust air is restricted from entering the rest of the data centre. Where the warm air is exhausted depends on the containment configuration.

In-Rack Cooling Solutions
In-Rack cooling is the most precise cooling available, as the rack and the air conditioner operate in tandem with one another. Cold air is forced to pass through the servers; hot air has no choice but to pass through the heat exchanger.

Depending on the product, In-Rack cooling will use chilled water or refrigerant as the cooling medium. The majority of products do not bring liquid into the actual server rack. The air conditioner is housed in an adjacent, but separate enclosure and the equipment at the rack level is still air cooled. Chilled water units will require connections to chillers for chilled water supplies and heat rejection will have an exhaust requirement.

In-Row Cooling Solutions
Conventional data centre cooling floods an entire room with cold air—an approach that works well at minimal power densities. Using Hot Aisle / Cold Aisle configurations, In-Row cooling offers capacity and efficiency gains by moving the air conditioner closer to actual load. Using fans Installed on the floor or suspended from overhead, in-row cooling units deliver local, focused cooling at the rows of server cabinets which fill the data centre.

Liebert / Emerson CRV Self-Contained Row-Based Data Center Cooling

The Liebert CRV is the perfect cooling solution for small computer rooms and data centres. It integrates within a row of data center racks, providing cooling close to the server heat source for efficient and effective data center management. The system features Liebert iCOM controls and a digital scroll compressor, resulting in high reliability and optimized system performance. The horizontal airflow is suitable for raised or non-raised floors.

Liebert CRV uses environmentally friendly R410A refrigerant, and is available in different versions, depending on data center design requirements:

- 20 or 35kW air-cooled and water-/glycol-cooled systems
- 40kW chilled water cooled systems
- Precision cooling and humidity control
- Installs within the row of racks
- Up to 10 racks per cooling unit may be monitored to improve system performance and report rack temperatures.

Liebert / Emerson XD Refrigerant based cooling

Liebert XD refrigerant-based cooling modules work as a system to support the hot aisle/cold aisle approach to cooling high heat density data centers. The modules provide focused rack cooling, enhancing a room precision cooling unit, such as a Liebert DS system. Pumped refrigerant is ideal for use around electronic equipment, operating at low pressure in the piping circuit, and becoming a gas at room conditions.

Liebert XD cooling modules are available in configurations to suit individual application requirements:

Liebert XDO overhead cooling module mounts directly above the cold aisle, requiring no floorspace. It draws in hot air from the hot aisle, then discharges cool air into the cold aisle where the equipment air inlets are located. Available with Smart Module integrated control board, for increased module control and monitoring.

Liebert XDV rack cooling module mounts vertically on or above the IT rack enclosure, requiring no floorspace. It draws hot air from inside the cabinet or from the hot aisle. It then cools the air and discharges it down to the cold aisle. Available with Smart Module integrated control board, for increased module control and monitoring.

Liebert XDR cooling module is designed to replace the back door of a server enclosure, providing cooling without increasing the rack footprint. The module uses the server fans within the protected rack to provide airflow, providing the most energy efficient design.

Liebert XDH row-based cooling module is placed directly in line with the rack enclosures, and requires very little floorspace. Air from the hot aisle is drawn in through the rear of the unit, cooled, and then discharged horizontally through the front of the unit into the cold aisle. Available with Smart Module integrated control board, for increased module control and monitoring.

Liebert XD CoolFrame cooling module is designed to install on the back of the Egenera Bladeframe EX system, providing cooling without increasing the rack footprint.
