Bitdeer Sealminer DL1 Air (25GH)

The DL1 Air delivers 25 GH/s of Scrypt hashrate at 3,725W wall draw and 149 J/GH efficiency in Normal mode at 25 degrees Celsius ambient. Bitdeer rates the unit at plus or minus 5 percent on hashrate and power efficiency with plus or minus 10 percent tolerance on total power consumption. Real world output typically ranges from 23.75 to 26.25 GH/s depending on ambient temperature, voltage stability, and operating mode selection.

The DL1 Air leads the current Scrypt market on efficiency. Against the Bitmain Antminer L9 at roughly 17 GH/s and 210 J/GH, the DL1 Air produces 47 percent more hashrate at 4 percent more power, working out to approximately 30 percent better efficiency per gigahash. Against the older Antminer L7 at 9.5 GH/s and 360 J/GH, the DL1 Air is 58 percent more efficient per gigahash and 163 percent more hashrate. For new Scrypt fleet deployments where long term operating cost drives economics, the DL1 Air is the strongest available option from a credible manufacturer.

Normal mode runs the rated 25 GH/s at 3,725W and 149 J/GH for standard daily operation and most deployment scenarios. High Hashrate mode pushes peak output beyond rated spec for operators with sub $0.05 per kWh electricity who prioritize maximum coin production over efficiency. Low Power Mode drops to 20.5 GH/s at approximately 2,788W and 136 J/GH, sacrificing 18 percent hashrate for 9 percent better efficiency. Use Low Power during expensive electricity peak hours, when LTC/DOGE prices dip, or when Scrypt network difficulty compresses margins. Mode switching happens through the management interface without firmware changes or downtime.

The DL1 Air mines six Scrypt coins simultaneously through merged mining: Litecoin (LTC) as the primary reward and largest market, Dogecoin (DOGE) as the largest merged secondary reward, plus Bellscoin (BELLS), Junkcoin (JKC), Luckycoin (LKY), and Pepecoin (PEP) through supporting pools. Combined revenue from merged mining typically runs 20 to 40 percent above solo Litecoin mining at the same hashrate, with the exact premium dependent on relative coin prices and network difficulties. Merged mining captures rewards without splitting hashrate, so you do not lose LTC production to earn the secondary coins.

220V AC input on a dedicated 20 amp commercial circuit. At 220V the unit draws approximately 16.9 amps continuously, which fits within a 20 amp breaker with minimal headroom. The DL1 Air is not designed for 110V residential power. European, Middle Eastern, and most Asian operators at 230V single phase run the unit directly off standard commercial circuits. North American operators need 240V service, typically requiring dedicated electrical panel work. PSU and cables ship included.

75 dB from high speed fans is standard industrial ASIC noise comparable to a vacuum cleaner at close range. Suitable for garages, basements with adequate ventilation, dedicated mining rooms, workshops, outbuildings, and professional hosting facilities. Not suitable for bedrooms, living rooms, home offices, or any shared living space. For home operators with noise constraints, consider hosting through MillionMiner's managed facilities rather than residential deployment.

Setup takes under 15 minutes. Step one: plug the PSU into the miner and into a dedicated 220V outlet at 20 amp capacity. Step two: connect Ethernet from the miner to your router or managed switch. Step three: power on and wait 60 seconds for boot. Step four: find the miner IP through your router's DHCP client list or a network scanner tool. Step five: open that IP in any web browser and log in with Bitdeer's default credentials (check documentation included in the box). Step six: navigate to Miner Configuration, enter your Scrypt pool URL in stratum+tcp format (for example stratum+tcp://litecoinpool.org:3333), set your Litecoin wallet address or pool worker name as the username, enter any placeholder password, save, and hashrate climbs to 24+ GH/s within 10 to 15 minutes.

LitecoinPool is the longest established Scrypt pool with full merged mining support for all six DL1 Air compatible coins. F2Pool offers broad multi algorithm coverage with competitive fees. ViaBTC supports merged mining with accumulation mode payouts that reduce variance. AntPool provides strong LTC pool hashrate and reliable uptime. Prohashing offers auto profit switching between Scrypt coins. Pool fees typically range from 0.5 to 2 percent. Verify that your chosen pool supports the full merged coin set you want (LTC, DOGE, BELLS, JKC, LKY, PEP) since smaller chains are not available on every pool.

At MillionMiner's onsite $0.08 per kWh calculator: $13.99 daily revenue against $7.15 daily electricity, netting $6.84 per day per unit. At $0.04 per kWh industrial rates, daily net approaches $10.20. At $0.12 per kWh residential rates, daily net compresses to roughly $3.00. Scrypt mining economics benefit from Litecoin's stable ecosystem and Dogecoin's consistent merged reward contribution. Revenue shifts with LTC and DOGE prices and Scrypt network difficulty. Run fresh calculations through WhatToMine or Minerstat with your specific electricity rate before purchasing.

Scrypt network difficulty has grown steadily but slower than Bitcoin because the Scrypt ecosystem is smaller and has fewer manufacturers producing hardware. The DL1 Air at 149 J/GH sits at the current efficiency frontier. For the machine to become unprofitable, Scrypt difficulty would need to rise enough that daily revenue falls below daily electricity cost at your rate. At $0.04 per kWh the DL1 Air has substantial difficulty headroom. At $0.08 per kWh the unit remains profitable at current conditions but has less buffer. At $0.12 per kWh the breakeven threshold is closer. Historically, dedicated Scrypt ASICs have maintained productive life of 3 to 5 years at industrial electricity rates.

The DL1 Air launched March 16, 2026 as the newest Scrypt hardware available from any major manufacturer. Bitmain's Antminer L11 Hyd 2U covers the hydro cooled tier at 35 GH/s but requires water cooling infrastructure. No imminent replacement for the DL1 Air has been announced. Waiting forfeits months of Scrypt mining revenue at current difficulty levels while the DL1 Air's 149 J/GH efficiency is still best in class for air cooled Scrypt deployment. For operations expanding Scrypt capacity now, the DL1 Air is the strongest available option.

Yes. Every Scrypt miner uses standard Scrypt Stratum protocol over Ethernet and connects independently to your chosen pool. Run the DL1 Air alongside Bitmain L7, L9, L11, Goldshell Mini DOGE units, or any Scrypt hardware in the same fleet without compatibility issues. Each unit operates independently with its own pool connection and worker name. Brand mixing is standard practice and provides supply chain diversification that reduces risk from single manufacturer issues. Fleet management tools including Foreman, Awesome Miner, and Hive OS handle multi brand Scrypt fleets through unified dashboards.

Acquisition cost of $9,999 at MillionMiner plus annual operating costs. Electricity at $0.08 per kWh runs approximately $2,610 per year per unit. Infrastructure overhead (internet, cooling, facility costs) adds 5 to 15 percent depending on deployment scale. Pool fees add 1 to 2 percent of gross revenue. Expected hardware lifespan at 3 to 5 years with proper maintenance. Annual maintenance budget approximately 3 to 5 percent of acquisition cost for replacement parts (fans, occasionally hashboards). Total three year TCO at $0.08 per kWh: roughly $18,800 per unit.

Bitdeer's warranty on the DL1 Air covers manufacturing defects and hardware failures under normal operation within specified environmental ranges. Confirm exact warranty duration with MillionMiner sales for your specific batch since terms can vary by region and distributor agreement. As a NASDAQ listed company with active global operations across four continents, Bitdeer provides ongoing manufacturer support that orphaned Scrypt hardware from defunct manufacturers cannot match. Firmware updates, fleet management tools, and warranty claims route through Bitdeer's operational infrastructure, which reduces the risk of being stranded with unsupported hardware over the DL1 Air's operational life.

The Bitmain Antminer L11 air cooled variant sits at 21 GH/s and roughly 175 J/GH, meaning the DL1 Air at 25 GH/s and 149 J/GH leads on both hashrate (19 percent higher) and efficiency (15 percent better per gigahash). The Bitmain Antminer L11 Hyd 2U at 35 GH/s and approximately 120 J/GH beats the DL1 Air on efficiency but requires hydro cooling infrastructure, costs substantially more, and fits different deployment tiers. For air cooled Scrypt deployments, the DL1 Air is the current efficiency leader against any current Bitmain offering.

Monthly fan cleaning with compressed air to clear dust buildup that reduces cooling efficiency and accelerates fan bearing wear. Quarterly inspection of hashboard connectors and chassis integrity. Semi annual firmware updates when Bitdeer releases patches. Continuous ambient temperature monitoring because most Scrypt ASIC failures trace back to thermal stress from poor ventilation. Every 18 to 24 months at full duty cycle, expect at least one fan replacement per unit. Budget approximately 3 to 5 percent of acquisition cost annually for replacement parts and maintenance labor. Bitdeer's manufacturer continuity means replacement parts remain available throughout the hardware's expected operational life.

Standard Stratum protocol makes the DL1 Air compatible with all major fleet management platforms including Foreman, Awesome Miner, Hive OS, and Braiins OS+. These tools discover the unit automatically on your network and provide unified dashboards for hashrate monitoring, temperature tracking, pool configuration, and alerting across mixed brand fleets. Bitdeer's own fleet management tools handle SEALMINER specific features like mode switching and firmware updates. For mixed fleets running Bitdeer alongside Bitmain or other Scrypt hardware, third party platforms provide the single pane monitoring most operators prefer.

High Hashrate mode serves as Bitdeer's factory supported overclock option, pushing output above the rated 25 GH/s for operators with cheap electricity. Third party firmware for Scrypt hardware is less developed than Bitmain's SHA-256 ecosystem because the Scrypt market is smaller, so most DL1 Air optimization happens within Bitdeer's stock firmware modes. For operators wanting aggressive tuning beyond High Hashrate mode, monitor Bitdeer's firmware release schedule for additional tuning features. The proprietary Low Power Mode provides the opposite direction for efficiency prioritization.

For operators building diversified Scrypt fleets, compare the DL1 Air against the Bitmain Antminer L9 series (17 GH/s) for capital efficient deployments on existing Antminer management systems, and the Antminer L11 Hyd 2U for operators with hydro cooling infrastructure who want maximum efficiency. For SHA-256 Bitcoin mining alongside Scrypt operations on shared facility infrastructure, the Antminer S21 XP at 270 TH/s pairs well with DL1 Air units on similar 220V 20A electrical circuits. For Kaspa diversification, the Antminer KS7 at 45 TH/s covers KHeavyHash mining on comparable power infrastructure. MillionMiner's ASIC hosting service accepts DL1 Air units at industrial electricity rates for operators who prefer turnkey Scrypt deployment.
