Product Description
Designed for growing hydro mining facilities, the AP-E28 Modular Liquid Cooling Cabinet focuses on higher rack density and centralized liquid cooling management.
It accommodates 28 Antminer S19, S21, and S23 hydro miners and operates at a total load of 154 kW, making it suitable for medium-to-large mining farms. The cabinet adopts a fully modular architecture, with independent power, cooling, and control sections that simplify expansion and system planning.
Its CDU integrates pumping and monitoring functions, enabling efficient coolant distribution across multiple cabinets.
Built to CSA and CE standards, AP-E28 supports fast installation and stable operation across global mining sites, delivering a practical and scalable hydro cooling solution for professional deployments.
Split-Type Intelligent CDU
The split-type intelligent CDU separates control and cabinet units, allowing one CDU to manage multiple cabinets. It provides centralized monitoring and one-click operation for efficient, scalable, and stable management of large-scale cryptocurrency mining rooms.
Flexible Power Scalability
The cabinet design supports modular power expansion from 200kW up to 1000kW, allowing mining farms to scale operations based on current demand and future growth—without the need for major infrastructure changes.
Intelligent PLC Control
PLC-based remote control enables one-click operation with 24/7 real-time monitoring, automatically responding to power, temperature, liquid flow, pressure, and network issues for stable operation and reduced maintenance.

Consider your hash rate, miner compatibility, available space, and future scalability when selecting liquid cooling.
Not sure what to choose? Contact us for a custom solution!
Liquid cooling systems are generally quiet due to reduced fan usage, making them ideal for home mining setups or office environments. However, under high load, noise from the water pump may become noticeable.
Most liquid cooling systems require specialized coolant for optimal heat transfer and low corrosion. You can either purchase it directly from us or buy coolant from a recommended brand locally.
Installation is straightforward but requires correct connection and coolant filling. Detailed guides are provided to help with setup. We also offer remote supervision through shared chats or video calls to assist during installation if you need it.
For larger projects upon individual agreement, on-site installation services are possible.
Yes, regular maintenance is necessary, such as cleaning radiators, pumps, and pipes to avoid dust or scale buildup. You may also need to change the coolant over time to maintain efficient cooling.
Yes, some models can recover heat for purposes like radiators, floor heating, hot water, or even heating a pool—allowing you to heat and mine at the same time!
