Passive cooling means the mining container relies solely on the miners' fans for airflow, without additional fans. While it can be effective, it can lead to reduced performance if inlet air filtration creates a strong vacuum, and if miners go offline, heat from the hot aisle can cause overheating of nearby miners, leading to downtime. Active cooling, which provides extra airflow from additional fans, prevents this issue. We recommend active cooling unless the client is in a cooler climate and has easy access to on-site maintenance.

A well-designed container should handle all weather conditions, from heat waves to snow storms. Just because you are mining in Texas doesn’t mean a freak snow storm can’t wipe out your expensive miners. Variable speed fans adjust airflow based on miners' needs, optimizing energy use and ensuring reliable hashrate. Single-speed fans can lead to excessive power use and more frequent filtration maintenance, and in winter, they may draw in fine snow, potentially damaging miners by providing unnecessary airflow.

Supply fans are upstream of the cold aisle, and exhaust fans are downstream of the hot aisle. Most air-cooled containers use exhaust fans, but they face two main issues: they operate at high temperatures (over 60°C) from the miner exhaust, which can cause motor failures, and they create a vacuum in the cold aisle that can draw in fine dust, snow or moisture through any cracks or holes, potentially damaging the miners. Common leak points are door jambs, wall penetrations and sealing areas around the filters.

Belt-driven fans can be manufactured more compact and at less cost than direct-drive fans, which is better for enclosure layout, however belts break frequently (especially if they are exhaust fans located on the hot aisle), resulting in more frequent downtime and maintenance.

A prefilter is meant to catch bugs and large debris to prolong the lifespan of the primary filters before they must be cleaned or replaced, saving money on filtration and reducing maintenance cost and downtime.

In cold climates, where snow can be a concern, it's crucial that heat recirculation directs heat upstream of the air inlet filters. Most containers recirculate heat inside the enclosure but downstream of the filters, which fails to melt snow on the filters and can lead to miner overheating from air blockage, or even filter collapse from the resulting pressure differential. Our patented system directs heat upstream of the filters, preventing snow or ice blockages and protects your valuable miners from catastrophe.

Unlike thermal circuit breakers, the hydraulic-magnetic circuit breakers trip point is unaffected by ambient temperature. After tripping, the breaker may be reclosed immediately since there is no cooling down time necessary.

Smart PDUs enable users to diagnose individual miners before scheduled maintenance. In remote locations with no full-time staff, remote management and automation are crucial for protecting miners from changing environmental and power conditions, providing great reliability. Our patented LoadSync™ controller automates all aspects of our mining products, including HVAC, PDUs, miners, and generators for the Hash Generator product line™. With LoadSync™, users can automatically synchronize mining load to power supply requirements. Whether you are mining off-grid with natural gas generators or on-grid on ERCOT’s CLR program, our automation has you covered.
