Airflow Systems

Server heat densities are increasing rapidly in government, institutional, financial and co-location applications, while HPC systems are designed to provide increased computational speeds within limited rack space. The Motivair Chilled Door® Rack Cooling System manages the critical cooling requirements of higher density server racks which cannot be effectively cooled with traditional air conditioning, in-row coolers or passive rear door coolers - and at the lowest possible energy cost.

The latest Motivair Chilled Door® is an "active" hinged door that replaces the rear door of any standard or OEM server rack via an interface frame. The Chilled Door® is capable of removing up to 45 kW per rack with 65F supply water, using less than 500 watts of fan power. Over 50 different variables are constantly monitored and controlled via a custom PLC to ensure that the Chilled Door® is actively adjusting to conditions inside the data center and the server rack. By actively removing 100% of the heat load at its source, the Motivair Chilled Door® system results in a "Heat Neutral" white space that requires little or no air conditioning. Hot aisle/cold aisle configurations are eliminated, data center square footage is reduced, raised floors are optional and energy efficiency can be increased by up to 90% compared to legacy cooling systems. The Motivair Chilled Door® always operates above the dew point of the data center, which eliminates the possibility of condensation near critical electrical equipment. 100% sensible cooling eliminates wasted energy by CRAC units or in-row coolers via accidental de-humidification and re-humidification. As a result, no condensate pumps or piping are required. The Chilled Door® was designed with an aluminum coil frame to reduce weight and eliminate zinc whiskers".

This Net-Direct™ Air Inlet Duct provides cold airflow directly into Cisco^ Nexus 9372 and 9332 switch intakes from below. Not only does it require no energy to operate, but it also reduces fan power consumption by up to 250W, improving energy efficiency and reliability for increased cost savings. Optimized for use in server cabinets, 1RU, Black, 1pc - No blanking panels.

Net-Direct™ Air inlet Duct, 2 RU that resides in-line and below switch provides cold aisle airflow to Cisco^ Nexus N2K-C2148T-1GE, N2K-C2248TP-1GE, and N2K-C2232PP-10GE fabric extenders and Cisco^ WS-C4948E-F, WS-C4948E-F-S, and WS-C4948E-F-E. Optimized for use in server cabinet applications.

Portable Close-Coupled Cooling with Customer-Inspired Upgrades for Better Performance

Award-winning SRCOOL12K, now in its second generation, is a portable, compact, self-contained air conditioning unit designed for server rooms, small network closets, back offices and other areas with heat-sensitive network switches and servers that facility air conditioning can't reach. Design improvements based on customer feedback include upgraded commercial-grade components designed to last longer, including an upgraded hot air exhaust fan. The SRCOOL12K Gen 2 also boasts robust packaging for better protection from shipping damage and an updated two-year warranty.

12,000 BTU of Cooling Power Protects Your Equipment Against Hazardous High Heat

This SmartRack® server room air conditioner pumps 12,000 BTU (3.5kW) of cooling into your IT environment to help prevent shutdowns, malfunctions and other failures caused by overheating or fluctuating temperatures. It uses environmentally friendly R410A refrigerant to comply with worldwide standards. An easy-to-read control panel with diagnostic LEDs provides convenient local management.

Rack/Spot AC Unit Focuses Cold Air Where It's Most Needed

Close-coupled air-conditioning delivers cold air near heat loads to discourage recirculation and increase energy efficiency. An included 71-inch flexible hose lets you aim the cold air to a specific spot, such as an overheated server rack or an equipment hot spot. Hot air exits through a window or drop ceiling via an included exhaust kit. An upgraded hot air exhaust fan maintains effectiveness even under a high heat load. The unit also dehumidifies and filters the air, providing better air quality that can enhance operating conditions and equipment reliability.

Commercial-Grade Components for Reliable Performance

With a 100-percent duty cycle, the SRCOOL12K can run continuously without costly downtime. It uses copper tubing that is stronger than the aluminum tubing used in most consumer cooling units. The copper allows higher pressures and better weld joints to stand up to the constant vibration of the running compressor.

Built-In Evaporator Ensures No Water Collection Tank to Empty

The evaporator expels the condensed water through the directional exhaust duct, eliminating the need for a drain tube, drain pan or water collection tank and saving you time and money. No external condenser, refrigerant piping or professional maintenance is required for simple operation. Upgraded firmware allows the compressor to cycle on and off while the evaporator fan stays on to prevent icing in high-humidity environments.

Add an Optional Remote Management Accessory for 24/7 Monitoring and Control

Install the optional SRCOOLNETLX network module (sold separately) to monitor temperatures, receive alerts, review logs and control settings from anywhere, anytime, via SNMP, web browser, SSH, telnet or command line interface. The built-in LX Platform's PowerAlert® Device Manager provides a single interface to cycle the connected air conditioner on and off, adjust its fan speed, change its target set point temperature and switch to dehumidification mode.
