Facility Liquid Integration Yes

Designed to manage the distribution of clean, treated coolant to and from a network of IT cabinets, the CHx750 accepts ASHRAE W4 warm facility water and manages 750kW of processor load per network. This stand-alone CHx can be customized to fit various data center environments. Standard equipment groups offer N+1 redundancy, and when deployed can provide tier 4 resiliency.

Features

  • Manages 750kW of processor load per network
  • Supports up to 900 servers
  • Compatible with ASHRAE W4 warm water cooling
  • Redundant centralized pumps
  • Intelligent Control System (Webserver, Modbus, SNMP)
  • 7″ LCD screen with touch functionality
  • Internal leak detection system
  • Integrated fill pump
  • 50 micron filtration to secondary loop

Benefits

  • Warm water cooling reduces need for chillers
  • Quick and easy installation and service
  • Significantly reduces OpEx
  • Isolates high pressure facility water from racks
  • Serviceable onsite – no down time for maintenance
  • High temperature return water can be used for heat re-use

Rack-based Liquid-to-Liquid CDU

Coolant Distribution Units
Cooling Capacity 80kW
Power Consumption 652W
Servers Managed 100
Facility Liquid Integration Yes

The CHx80 meets today’s most demanding HPC requirements. Capable of managing 80kW+ of heat load in a remarkably small 4U of space, this system provides cooling for 120 servers or more. The CHx80 is an extremely efficient heat exchanger that uses ASHRAE W4 warm water to manage processor and component heat. As a result, users can expect a significant reduction in data center OPEX.

Features

  • Manages 80kW+ of processor load per network
  • Compatible with ASHRAE W4 warm water cooling
  • Redundant centralized pumps
  • Dry-break quick disconnects
  • 4.3″ LCD screen with touch functionality
  • Integrated Command2 control and monitoring system (Webserver, Modbus, SNMP)
  • Internal and external leak detection system
  • 4U rack-mount chassis

Benefits 

  • Warm water cooling reduces the need for chillers
  • Manages up to 100 servers per rack
  • Quick and easy installation and service
  • Consumes only 652W
  • Can be located anywhere in a rack
  • Servers remain hot-swappable for service
  • High temperature return water can be used for heat re-use

Rack-based Liquid-to-Air CDU: liquid cooling without facility water

rack-dclc-cool-it-release
Power Consumption (Max) 720W
Racks per Solution 1
ROI (months) 1-12
Facility Water Integration No

The AHx10 is a compact 5U, rackmount CDU capable of managing 7kW at 25°C ambient air temperature. This product expands to a 6U and 7U configuration (via the available expansion kit) that manages up to 10kW of heat load. The AHx10 supports front to back air flow management and is compatible with CoolIT Passive Coldplate Loops and Rack Manifolds. The system allows users to deploy high density liquid cooled servers inside existing data centers without the requirement for facility liquid. The AHx10 is the perfect solution to manage cooling for HPC racks within an existing facility.

Features

  • 7 – 10kW of heat load management
  • 25°C ambient air temperature
  • Liquid-to-Air heat exchanger
  • Redundant pumping
  • Redundant power supply
  • Compact 5U, rackmount appliance
  • 6U or 7U expansion kit available
  • Integrated monitoring and control system with remote access
  • LCD touch display for quick user interface
  • Rackmount appliance – support cold to hot aisle configuration

Benefits

  • Allows for dramatic density increase and rack utilization
  • Quick and easy installation and service
  • Control and monitoring from LCD or via several network protocols
  • System can be located at any level within the rack
coolit systems rack dclc ahx2 logo

An essential factory burn-in tool for OEMs and System Integrators

coolit systems rack dclc ahx2
Power Consumption (Max) 200W
Servers per Solution 4
Facility Water Integration No

The AHx2 is a compact, easy to transport air CDU designed to enable factory server burn-in when liquid is not present in the factory. It functions as an important tool for customers wishing to validate DCLC technology with a small number of servers. AHx2 provides direct liquid cooling to four DCLC enabled servers during the burn-in process, and reduces the need for additional infrastructure. AHx2 is a Liquid-to-Air CDU which dissipates heat from the coolant in the server loop to the ambient environment, and accompanies the servers through the entire burn-in process.

Features

  • 2kW of heat load management
  • Manage four DCLC enabled servers simultaneously
  • Compact size allows the unit to sit on top or beside a server chassis during operation
  • Carrying handle and rubber feet for safe transportation and storage
  • Non-marking skid pad allows the unit to safely sit on top of a server chassis
  • Status light to indicate correct unit operation

Benefits

  • DCLC enabled servers can be thermally tested during the factory burn-in process, without additional expensive liquid cooling infrastructure
  • System travels with the server through factory burn-in process
  • Inexpensive solution for DCLC enabled server burn-in
  • Quick and easy installation and operation
