APPLICATION : Servers rooms Data Centers Laboratories Clean Room Telecommunication Close Control Unit (CCU) also Know as Precision Air Conditioner or Close Control Air Conditioner or Computer Room Air Conditioner (CRAC) or server room air conditioner use for precise control of Temperature and Humidity required for critical application like Server room, Datacenter, Laboratories, Telecommunication room etc. Modern IT, Telecommunication & laboratory equipments generates a large amount of heat. The problem further increased with higher density IT kit (e.g. Blade Servers). It is, therefore very essential to use the correct type of precision cooling for server room cooling or Datacenter cooling. Also it is very important to understand air flow requirements within server room & Datacenter. Failing to achieve this can have disastrous results with "deadly" hot-spots just where you don't need them - around your key mission critical servers. Hence efficient precision air conditioning for data center cooling (for cooling server and equipments) is critical factor. In Nutshell Electronic and information procession equipments requires rigid environment conditions with précised control of temperature & humidity for reliable operation. Close control air conditioning systems is specifically designed for concentrated vertical heat loads of today's data centers. Precision Air Conditioning systems provides efficient heat removal, excellent humidity control, greater airflow, better air filtration, greater flexibility and expandability with numerous alarms and redundancy options. Precision Air conditioner for server room cooling is available in up flow or down flow type based on air throw. Based on coolant and positioning of coil it is broadly classified into Chilled Water (CW) type and Direct Expansion (DX type) type or Dual Fluid (Chilled water + Direct expansion) type. Some of reputed brands are AIREDALE, Liebert, Denco, Uniflair, stulz, Emicon, blue box etc. Key Benefits of Close Control Air Conditioning system over converional Air Conditioner are as follow: Precise control of Humidity & temperature along with cleanness : Electronic & Information processing equipments requires environment with precise temperature and humidity control with cleanness. Close Control Unit provides not only precise control of temperature and humidity but also air filtration to remove airborne particles which can cause problems. Reliable operation for 365 days a year: Most of critical application such as Data center, server room, telecommunication rooms etc requires 24x7 availability of cooling environment with précised control of temperature and humidity. Close Control air conditioning Unit is designed run for 365 days 24x7. Energy Saving: Close Control Unit offers a choice of compressor type. Microprocessor control and other optional features are designed to reduce power consumptions and maximize energy saving. This helps in fast Return of Investment (ROI). Cooling of critical Spaces: Close Control Unit offer option of down flow and up flow type. Also it can be designed with maximum air flow so that cool air should reach to all corners of datacenter.

Backbone to ensure highest availability of pure power depends on effective power distribution and its conditioning. Power distribution can be Achieve with help of panels, sockets, cables, Automatic transfer switch (ATS), Generator and PDU. While conditioning of power can be done with help of TVSS, K rated Isolation transformer, UPS etc. Ctrltech ensures proper distribution of conditioned power with help of series of equipments like K rated Isolation Transformer, Automatic.Transfer switch (ATS), Transient Voltage Surge Suppressor (TVSS), Power Distribution Units (PDU). Let's have brief description about these equipments.. K rated Isolation Transformer:  Basic function of Isolation Transformer is to isolate two circuits (input and output). K rated Isolation Transformer is to deliver conditioned power to a nonlinear high-harmonic current load (such as computers) and operate at safe temperatures while minimizing the harmonic current delivered to the power grid. An additional function of this transformer is to attenuate both common mode and transverse mode noise going to the load. Nonlinear load handling capacity of isolation transformer is depends its "K" rating. K rating available form K-4 to K-20 designed to handle nonlinear load of 35% to more than 75% simultaneously. Transient Voltage Surge Suppressor (TVSS):  lectric power line disturbances such as high voltage transients can disrupt or damage sensitive electronic equipment - causing a major loss in productivity and money. TVSS is the reliable way to keep these power problems from getting into your facility in the first place. Automatic Transfer switch (ATS):  Transfer switches allow switching from a primary power source to a secondary or tertiary power source and are employed in some electrical power distribution systems. Most often transfer switches can be seen where emergency power generators are used to back up power from thesource. The transfer switch allows switching from utility power to emergency generator power. The switch is either a manual switch, an automatic switch or a combination of manual and automatic. During a power outage, the transfer switches isolate the emergency circuits from the utility line allowing for efficient operation of the generator without back feeding onto the utility.. Automatic transfer switches continually monitor the incoming utility power. Any anomaly such as voltage sags, brownouts, spikes or surges will cause the internal circuitry to command a generator startup and then a transfer to the emergency generator when additional switch circuitry determines the generator has the proper voltage and frequency. When utility power returns, or no other anomalies have occurred for a set time, the transfer switch will then transfer, back to utility power and command the generator to turn off after another specified amount of "cool down" time. Power Distribution Unit (PDU):  PDU also refers to what amounts to a well-constructed power strip suitable for datacenter use. PDUs can be dumb type meaning that they have no instrumentation and are not manageable, or they can be metered type meaning that they are equipped with a display that shows current load on each phase, or they can be switched type meaning that some or all of their receptacles can be individually switched on or off remotely. Some PDUs provide a means of remote access. Common methods are a RS-232 serial connection or a computer network controller that can be accessed though TELNET, SSH, SNMP or a Web page. This allows an administrator to access the PDU from a remote terminal and interface with the it to turn on or off outlets, schedule power shutdowns, control load, etc. This can be helpful if a remote machine has gone into an unresponsive state and cannot be restarted though normal means. A administrator can connect to the PDU the machine is plugged into and Power cycle the machine
