Engineering Built for Continuous Operation

Every DroLin CDU is designed around one principle: zero unplanned downtime. Dual redundancy, field-serviceable
components, and real-time monitoring come standard across the entire range.

01 — REDUNDANCY

N+1 Dual-Pump Architecture
Two fully independent pump loops run in parallel 
— one active, one on standby. If the primary 
pump fails, the backup activates instantly with no
interruption to cooling flow. Pumps are hot-swappable 
without shutting down the system.
 

02 — HEAT REJECTION

SS304 Stainless Steel Plate Heat Exchanger
High-efficiency plate-type heat exchangers manufactured
from 304-grade stainless steel provide superior corrosion
resistance and thermal performance. The secondary loop
stays fully isolated from facility water — protecting your
mining hardware from contamination.

03 — FILTRATION

Online-Replaceable Filter System
Proprietary filter cartridges can be replaced during live
operation without stopping coolant flow. No scheduled
maintenance windows required — service your filtration
system whenever needed, without affecting hashrate.

04 — TEMPERATURE CONTROL

Precision Outlet Temperature: 35°C ± 1°C
Integrated PLC-based control maintains outlet coolant 
temperature within ±1°C under varying ambient conditions
and load changes. Stable inlet temperatures directly translate
to stable hashrate and extended ASIC lifespan.

05 — ACOUSTIC DESIGN

≤55 dB(A) Noise Floor
Industrial-grade pump isolation mounts and vibration
dampening reduce operating noise to ≤55 dB(A) — 
well within commercial and warehouse deployment 
standards, enabling installation in noise-sensitive 
environments.

Where DroLin CDUs Deploy

Designed to integrate into any liquid-cooled computing environment — from
containerized mining farms to enterprise data centers and hybrid energy sites.

Bitcoin Mining Farms

Pair with DroLin liquid cooling containers for end-to-end mining infrastructure. CDUs maintain stable 35°C coolant to Hydro ASICs — enabling sustained overclocking and maximum hashrate density per MW.

Containerized Data Centers

Drop-in CDU integration for 40HC and 45HC containerized computing deployments. Compact footprint fits within standard container dimensions. Ships pre-commissioned and ready to connect.

Renewable Energy Sites

Low-power CDU design pairs with solar and hydro-powered mining operations. Minimal auxiliary power draw ensures grid-independent sites maximize renewable energy utilization with PUE approaching 1.06.

Enterprise Colocation

Enterprise CDUs integrate directly into existing chilled water loops via facility connection ports. Support standard BACnet/Modbus building management protocols for full BMS integration.

HPC & AI Infrastructure

High rack density GPU servers generate 10–30kW per rack — beyond air cooling limits. DroLin CDUs maintain precise coolant temperatures for continuous HPC and AI training workloads.

Warehouse & Industrial Sites

Industrial-rated enclosures withstand dust, humidity, and wide temperature swings. IP54-rated CDU bodies are suitable for warehouse, semi-outdoor, and factory-floor mining deployments.

FAQ

What is a Coolant Distribution Unit (CDU) and how does it work?

A CDU is the central thermal management unit in a liquid cooling system. It circulates coolant between your IT equipment (miners or servers) and the facility’s heat rejection system (dry cooler or cooling tower). The CDU maintains a clean, closed secondary loop — keeping your hardware isolated from facility water and controlling coolant temperature, pressure, and flow rate automatically.

Which CDU capacity do I need for my mining farm?

Calculate your total ASIC power draw and add 20% headroom. For example, 200 × Antminer S21 Hydro (5,360W each) = 1,072kW total — a 1MW CDU with adequate margin. Our engineering team provides free capacity sizing consultations for any project above 500kW.

Are DroLin CDUs compatible with Antminer S19/S21 Hydro and Whatsminer M56?

Yes. All DroLin CDUs are fully compatible with Bitmain Antminer S19/S21 Hydro series, MicroBT Whatsminer M56/M30/M50 series, and Canaan Avalon Hydro miners. Coolant outlet temperature of 35°C ±1°C meets manufacturer specifications for all major ASIC brands.

What coolant types do DroLin CDUs support?

Standard configuration supports purified (deionized) water and water-glycol mixtures for cold-climate deployments down to -20°C ambient. We also support custom coolant specifications for special applications — contact us to discuss corrosion inhibitor requirements for your site.

What is the lead time from order to delivery?

Standard models (200kW–1MW) ship within 15–25 business days from order confirmation. Custom configurations or high-volume orders: 30–45 days. All units ship pre-commissioned from our Hangzhou factory with full test reports included.

Do CDUs require a dry cooler or cooling tower on-site?

The CDU requires a heat rejection unit on the primary (facility) side. The 100kW model includes a dry cooler. Larger models (200kW–1MW) require a separate dry cooler or cooling tower sized to match — we supply these as part of a complete cooling solution and can help specify the correct unit for your climate and site.
