1、Heat Source
AI / HPC Load
Liquid-cooled racks, mining systems or process equipment.
2、Loop Control
CDU
Isolates loops and manages pressure, flow and temperature.
3、Heat Rejection
Dry Cooler
Transfers liquid heat to outdoor air through the V-coil.
4、Site Layer
DCIM / BMS
Receives operating status and alarm data through open protocols.
5、Circuit Flow
Hot return flows from load to dry cooler for heat rejection, cool supply from dry cooler to load.
Use free cooling first
Add adiabatic support only when needed
temperature or heat load requires additional capacity.
WET CURTAIN OFF
Pure Dry /Free-Cooling Mode
Ambient air passes directly across the heat-exchange coil. The process liquid stays inside a closed circuit, with no process-water consumption and no normal visible plume.
Best Operating Window
Use when ambient dry-bulb temperature and the required supply-liquid temperature provide enough approach margin.
Energy profile
Fans and circulation pumps still consume power, but compressor-based heat rejection can be avoided when design conditions permit.
Water strategy
Zero process-water use during pure dry operation.
WET CURTAIN OFF
Adiabatic Pre-Cooling Mode
A controlled water film pre-cools incoming air through evaporation before it reaches the coil. This extends heat-rejection capacity during high dry-bulb conditions while limiting annual water use.
Automatic activation
Temperature-based logic enables pre-cooling only when ambient conditions or load require it.
Low carryover design
Dedicated media and water distribution are selected to limit droplet carryover toward the coil.
Cold-weather shutdown
An optional self-draining water package supports clean seasonal shutdown and freeze protection planning.
AUTOMATIC SWITCHING
PLC logic stages fans and optional adiabatic support around the operating setpoint.
WATER USED BY DEMAND
Water is reserved for high-temperature or peak-load periods instead of continuous evaporation.
SELF-DRAINING OPTION
Drainage logic and low-temperature packages are available for cold-climate projects.

FAQ
Clear answers shorten technical review and help us configure the correct CDU before quotation.
Selection starts with total heat load, required fluid inlet and outlet temperatures, maximum ambient dry-bulb temperature, altitude, glycol concentration, allowable pressure drop and the required approach temperature. Redundancy and acoustic requirements are then added to the equipment selection.
Current project configurations cover approximately 500 to 3000 kW. Final capacity, fan quantity and dimensions depend on the defined operating condition. Larger 2-5 MW facilities can use coordinated multi-unit arrangements.
The controller enables adiabatic pre-cooling when outdoor temperature or load requires additional capacity. The objective is to use pure dry operation for as many annual hours as the site conditions allow.
Engineered configurations are available for water, water/glycol mixtures, lubricating oil, ammonia and CO2. Coil material, pressure class, seals and design temperature must be selected for the actual medium.
Yes. EC fans support high-efficiency speed control and lower part-load power. AC fans provide a cost-effective industrial option. Fan type is selected around energy goals, controls, sound limits and budget.
Yes. PLC and touchscreen control can support Ethernet, Modbus or Modbus TCP communication, with API-based integration available for project requirements.
Yes, when the fluid concentration, low-temperature controls, drainage logic and components are engineered for the minimum site temperature. The adiabatic water circuit also needs a defined winter shutdown strategy.
Certification must be confirmed for the selected model, components and project scope. Company, container, component and complete-equipment certifications are different and should not be treated as interchangeable.
