Hyperscale knowledge centres are giant business-critical amenities that course of important volumes of information, compute and storage providers. The deployment of superior cooling options is essential to keep up optimum working temperatures and scale back power consumption.
CRAH models are a go-to resolution for circulating cool air by means of the server racks, and Lennox EMEA has taken a brand new method to the appliance of the expertise.
Engineering-led design
The brand new CRAH – ApX Sequence chilled-water knowledge centre unit gives cooling capability from 20 kW to 500 kW in each single and “back-to-back” preparations. That includes business recognised controls and newest technology elements, the modular design ensures seamless integration into numerous knowledge centre layouts, together with raised ground and onerous ground configurations. Choices can be found for twenty-four completely different measurement models.
“Our CRAH – ApX Sequence takes a unique design path to that of typical options,” explains Matt Evans, CEO. “It gives quite a lot of robustly engineered commonplace case sizes, an method that permits us to tailor the design. Internally, elements akin to the dimensions and kind of followers, the design of warmth exchangers, optimally configured piping layouts, valves, and particular management necessities, can all be designed to swimsuit the person knowledge centre. This flexibility and flexibility delivers a extra tailor-made means of assembly exact utility necessities, relatively than merely providing the nearest-fit resolution.”
Lennox EMEA is aware of from expertise that the facility necessities of every knowledge centre rack fluctuate enormously from web site to web site. Because of this, the necessity for a extra engineering-led, granular and versatile degree of cooling design is clear.
Most efficiency
Power effectivity is a cross-component theme with the CRAH – ApX Sequence. For example, the superior Lennox EMEA branded warmth exchanger design ensures optimum efficiency by tailoring coil geometry, circuiting, fin sort, materials and pitch.
Notably, Lennox EMEA has superior functionality of producing warmth exchangers, borne out from a long time of market main HVAC merchandise, not solely optimising lead occasions but additionally lowering the carbon footprint and prices related to transport.
EC fan expertise is utilised throughout the product-set with a spread of sizes and choices together with built-in Energetic Energy Issue Correction (APFC) for management of general Complete Harmonic Distortion (THDi).
Take management of cooling
With the choice of a regular or superior touchscreen management system, the CRAH – ApX Sequence offers wholistic monitoring, efficiency administration, and integration with knowledge centre infrastructure options.
The vary comes outfitted with business commonplace networking protocols to manage, monitor, and report operations akin to fan velocity, cooling efficiency, and alarms in actual time. Built-in fail-safe mechanisms allow uninterrupted operation within the occasion of energy failures, assembly the essential uptime necessities of information centres. The CRAH – ApX Sequence contains computerized switch switches and ultra-capacitor back-up, enabling speedy fan restart following energy restoration.
Built-in unit-to-unit community communication is featured as commonplace permitting for superior management performance together with teamwork modes, standby rotation, cascade operation, auto restart delay and rotating grasp operate, all with out the necessity of a devoted sequencing panel.
Programme of merchandise
“The brand new CRAH – ApX Sequence additional strengthens our dedication to delivering market-leading cooling options that assist the operational calls for of hyperscale and co-location knowledge centres. It’s the first in a programme of merchandise designed particularly for subsequent technology amenities,” says Matt Evans.
Backed by a group of extremely expert and skilled professionals, Lennox EMEA already offers a complete vary of scalable, high-efficiency cooling programs for high-performance knowledge centre environments. The addition of this new high-performance CRAH, together with the forthcoming CDU and FWU provides to an already sturdy portfolio which incorporates shut management models (CCUs), pc room air handler (CRAH) models, fan wall models (FWU), coolant distribution models (CDUs), chillers and dry coolers, all backed by intensive aftersales assist.
