COOLING SOLUTION FOR HIGH-DENSITY IT ENVIRONMENTS

Server rack density is permanently increasing with advanced technology and computing power requirements. At the same time, data centers are not expanding at the same rate as their computing power and this leads to significant load density growth which will continue into the foreseeable future.

Lambda In-Row CW has been designed to efficiently handle large volumes of air in high-density IT environments and provide reliable and precise cooling of server cabinets.

As hot aisle/cold aisle is an accepted practice for server cabinet layout within a data center, we designed Lambda In-Row CW units compatible with existing aisle containment solutions. Easy in installation and maintenance, these cooling units also offer the best total cost of ownership.

MICROCHANNEL EVAPORATORS

Heat exchangers of Lambda In-Row CW are microchannel coils combined in V-form to maximize heat transfer surface area. This design has several strengths inherent in microchannel heat exchangers:

  • High heat transfer performance
  • Low air pressure resistance
  • Low internal volume
  • Low heat exchanger weight

The aforementioned advantages result in significantly higher cooling capacity, reduced fan power consumption, simplified unit construction, and lastly, higher system efficiency.

FEATURES AND FUNCTIONALITY

  • Water Circuit

    Water circuit equipped with a smart balancing system based on continuous pressure drop measurements on return and bypass lines. Depending on these measurements, the unit control system adjusts two-way valves and maintains necessary cooling media flow through the cooling coils, thus avoiding manual fluid circuit balancing. Lambda’s automatic balancing system fits ideally for variable-flow chilled water systems.

  • Rack Compatibility

    Lambda In-Row housed in a standard 1200mm depth enclosure and can be easily inserted into the rack row to transmit airflows across the front of the server racks located on both sides of the cooling unit to provide even cooling over the height of the server racks. The internal construction is designed to allow easy maintenance with quick access to any component. The unit enclosure allows bottom or top (optional) fluid connections and cable entry.

  • Air Filtration

    Ultra-thin G2 grade air filters have been engineered for high-velocity applications and deliver excellent air quality and extremely low air resistance throughout the service life of the filter. The filter panels feature fibers which do not absorb moisture and will not support microbial growth.

Smart Control Strategies

The control hub of Lambda In-Row is a sophisticated microprocessor with control logic specially developed for row-based cooling units.

Users can adopt various control strategies based on either continuous temperature control, or on-demand airflow control, or continuous pressure control by maintaining a pressure differential between the cold and hot aisles.

HOT-SWAPPABLE FANS

For cooling equipment used in mission-critical or 24/7 environments, redundant and hot-swap, components are essential. Our in-row units feature hot-swap fan assemblies that facilitate the fan replacement on running units without disrupting the service. When the fan goes offline, the remaining fans will compensate for the lack of airflow by increasing the rotation speed.
