Cooltechx manufactures data center cooling equipment for server rooms, data halls and high-density computing environments. Our range includes computer room air conditioners (CRAC), in-row air-conditioning units and liquid-to-liquid coolant distribution units (CDUs).
Room and row-based air conditioning manages heat through controlled airflow, while CDUs transfer heat between the IT coolant loop and the facility cooling-water system. Equipment is selected around rack heat loads, operating temperatures and the site’s air or liquid-cooling architecture.

Computer room and row-level air cooling
Compare room-based CRAC units and in-row air-conditioning equipment against the IT load and airflow design.
For defined liquid-cooling interfaces
Liquid-to-liquid coolant distribution for facility and IT cooling-loop integration.
| Design area | CRAC / air conditioning | Liquid-to-liquid CDU |
|---|---|---|
| Heat path | Conditions air serving the room, row or equipment zone. | Transfers heat between facility-water and IT-side liquid loops. |
| Integration | Match air distribution, installation position and heat-rejection arrangement. | Match facility supply conditions, secondary flow and hydraulic interfaces. |
| Capacity basis | Compare sensible load and performance at the stated room and ambient conditions. | Compare heat transfer at stated fluid temperatures, flow and pressure conditions. |
| Controls | Coordinate temperature, humidity where specified, alarms and monitoring. | Coordinate pump control, fluid monitoring, alarms and site communication. |
| Project boundary | Confirm indoor/outdoor equipment and installation scope. | Confirm upstream cooling availability; a CDU is not automatically a refrigeration chiller. |
Compare data center cooling suppliers by IT load, temperatures and interfaces.
Document room and rack heat loads, operating conditions, airflow constraints and the boundary of the cooling scope.
Decide whether the load is served through conditioned air or a defined IT coolant loop; coordinate the facility cooling system.
Review power, monitoring, communication, piping or refrigerant interfaces, redundancy requirements and maintenance access.
Understand the boundary between facility cooling and the IT-side coolant loop.
Review how rack, row and room-level CDU arrangements affect integration.
Practical answers before equipment selection.
Yes. It provides routes to CRAC units and liquid-to-liquid CDUs. They serve different parts of the data center cooling architecture and should be selected against a defined project boundary.
Not necessarily. The liquid-to-liquid CDUs listed here transfer heat between two loops and depend on suitable upstream facility cooling conditions. Confirm the selected model and the complete cooling-system scope.
Start with the heat-load distribution, air paths, rack layout, return-air conditions and service space. Installation position alone does not establish the required capacity.
No. The thermal design must also define operating temperatures, airflow or coolant requirements, facility conditions, control interfaces and the intended cooling coverage.
No. Air conditioners condition air, while a liquid-to-liquid CDU serves a defined liquid-loop interface. A data center may require both as part of its thermal architecture.
Provide layout drawings, heat loads, operating conditions, available facility cooling, power, monitoring requirements and the intended installation and service scope.
This catalogue describes cooling equipment. Confirm the exact supply boundary, supporting equipment and integration responsibilities for the selected product.
For custom data center cooling configurations, share the room and rack heat-load profile, site conditions, equipment arrangement and drawings. OEM requirements can be reviewed against the selected equipment and agreed integration scope.
