Data sheet ~ Danfoss CoolTrain ~Data sheet Danfoss CoolTrain
Description
The CoolTrainis an advanced, pre-assembled hose solution tailored for liquid cooling in data centers. Featuring a pressure independent flow control valve (PICV), it ensures efficient energy transfer and reduced pumping costs. The system connects the building's supply and return headers (technical water loop - TCS) to individual racks, with a supply line marked by a blue hose and a return line marked by a red hose.
Danfoss CoolTrainintegrates the AB-QM valve in the supply line and the AMZ motorized isolation valve in the return line, creating a compact and time-saving connection set. This design optimizes hydronic balance in direct-to-chip cooling applications with variable flow, regulated by the AB-QM pressure-independent control valve. With easy installation and robust safety features, including interlockable FD83 couplings and remote monitoring capabilities, the CoolTrainoffers reliability and energy efficiency for modern data centers.

- Optional NovoConEnergy temperature sensors.
- Remote commissioning and presets.
- Real-time flow and energy data.
Safety Functions:
- Interlockable couplings for security.
- Motorized isolation ball valve for shut-off.
- Alarms and failure alerts via NovoCon?S.
Energy Efficiency:

Applications
The CoolTrainunit is installed between the technical water loop (TCS) and the data rack. It is suitable for both direct to chip and rear door cooling racks.
Depending on the required cooling capacity, multiple CoolTrainunits can be connected to a single data rack.
To enable remote shut?off of the water supply to the data rack, the supply and return actuators can be connected to a controller.
The pressure?independent control valve (AB?QM) regulates the required flow to the data rack and maintains hydronic balance in the system. This pressure?independent design ensures precise, dynamic control of each data rack without being affected by pressure fluctuations in the TCS loop.

Installation
The CoolTrainTM is intended for indoor installation. Before installation, remove the dust caps from both couplings. The CoolTrainTM is delivered pre-filled with PG25 and closed couplings. During installation, connect the couplings to their counterparts in the TCS line and data rack. Ensure that the remaining system is properly flushed and deaired prior to installation to prevent any operational issues. Once securely mounted, the couplings can be opened.
Presetting of flow
The calculated flow can be adjusted easily without using special tools. Either using digital actuator or manually turning the scale as described below.
AB-QM Setting:0=0% (10-100-)
Factory setting is 100%.
Change of presetting steps:
- Remove the blue protective cap or the mounted actuator
- Turn the pointer (clockwise to decrease) to the new setting
