Description

Bitdeer SEALMINER A4 Pro Air — 336 TH/s / 3662W SHA-256 ASIC Miner

Manufacturer: Bitdeer Technologies Group (SEALMINER) Launched: April 7, 2026

Overview

The SEALMINER A4 Pro Air is the air-cooled entry point into Bitdeer’s new A4 series, built on the company’s proprietary SEAL04 chip. It delivers 336 TH/s at 10.9 J/TH — a significant efficiency jump over the prior A3 generation (12.5–14 J/TH) — without requiring any liquid cooling infrastructure. It’s positioned for operators who want A4-generation efficiency gains but can’t support hydro-cooled deployments, trading some hashrate density against the A4 Pro Hydro and A4 Ultra Hydro for a simpler air-cooled setup.

Key Selling Points

• 336 TH/s at 10.9 J/TH — a major efficiency step up from the A3 series, with no liquid cooling required
• Refined thermal architecture rated for a wide -20°C to 50°C operating range
• Compact, high-density air-cooled footprint, maximizing hashrate per square foot and lowering total cost of ownership per terahash
• Low-noise operation relative to prior air-cooled SEALMINER generations
• Built on Bitdeer’s SEAL04 chip, part of a roadmap targeting ~5 J/TH at the chip level in future generations
• Backed by Bitdeer’s proprietary fleet management tools alongside standard Stratum compatibility
