ElphaPex DG Hydro 1 20G Dogecoin Miner Overview

The ElphaPex DG Hydro 1 (often listed as Elphapex DG Hydro 1) is a premium, hydro-cooled ASIC (Application-Specific Integrated Circuit) miner from ElphaPex, a Chinese hardware specialist focused on Scrypt-based equipment. Released in March 2025, it’s optimized for mining **Dogecoin (DOGE)** and **Litecoin (LTC)** using the Scrypt algorithm. Its standout feature is the advanced hydro-cooling system, which uses just 1 liter of liquid coolant for superior heat dissipation, quieter operation (around 50 dB), and better efficiency in demanding environments. This makes it a top pick for large-scale or professional farms, though its high power draw rules out casual home use.

The $8,200 USD price you mentioned aligns with listings on sites like asicminermarket.com (and similar retailers like Asic Marketplace), where it’s often bundled with the PSU and shipping options. Prices can fluctuate based on stock, region, and promotions—current averages hover at $7,500–$8,500 USD for new units. Profitability in late 2025 (with DOGE ~$0.18–$0.22) estimates ~$15–$25 daily revenue per unit before electricity costs, but factor in your kWh rate (under $0.08/kWh ideal for positive ROI).

#### Key Specifications
Compiled from manufacturer data and retailer specs (e.g., CryptoMinerBros, MillionMiner, X-ON Mining):

| Specification | Details |
|————————|———————————-|
| **Hashrate** | 20 GH/s (gigahashes per second) |
| **Power Consumption** | 6200W (high; requires industrial-grade setup) |
| **Efficiency** | 0.31 J/MH (solid for hydro-cooled Scrypt; ~20% better than air-cooled rivals) |
| **Algorithm** | Scrypt (DOGE, LTC, and compatible coins like Bells) |
| **Cooling** | Hydro-cooled (water-based; 1L coolant needed; ~50 dB noise—much quieter than air models) |
| **Dimensions** | ~530 x 320 x 250 mm (bulkier due to cooling reservoir) |
| **Weight** | ~25 kg (heavier from coolant system) |
| **Input Voltage** | 200–240V AC (dedicated high-amp circuit essential) |
| **Operating Temp** | 5–45°C (41–113°F); humidity 5–95% (non-condensing) |
| **Warranty** | 180–365 days (covers defects; coolant system included) |
| **Price (as of Sep 2025)** | $7,500–$8,500 USD (e.g., $8,200 on asicminermarket.com; includes PSU in most bundles) |

#### Features and Performance
– **Hydro-Cooling Edge**: Unlike air-cooled miners (e.g., the DG2 at 75–80 dB), this uses a closed-loop water system for stable temps and low noise—perfect for urban or multi-unit farms. It requires minimal maintenance (refill coolant every 6–12 months).
– **Mining Optimization**: Auto-switches between DOGE/LTC pools (e.g., F2Pool, AntPool). Supports overclocking for +5–10% hashrate, but monitor heat closely.
– **Build Quality**: Rugged aluminum frame with integrated PSU; Ethernet connectivity for easy pool setup. Rated for 24/7 runs in pro environments.
– **Profitability Estimate** (approximate, via ASIC Miner Value; assumes $0.10/kWh electricity):
– Daily revenue: ~$18–$28 (at 20 GH/s, current network difficulty).
– Daily cost: ~$15 (power only).
– Net: $3–$13/day (ROI in 6–18 months; scales with DOGE price surges).
– Volatility note: Scrypt difficulty up ~40% in 2025—DOGE hype drives this.

#### Pros and Cons
| Pros | Cons |
|——————————-|———————————–|
| Excellent cooling for low noise & high uptime | Very high power use (not for home grids) |
| Strong efficiency for Scrypt farms | Premium price; coolant setup adds minor hassle |
| Reliable for DOGE/LTC profitability | Bulky/heavy; shipping can add $200–$500 |
| Long warranty & easy integration | Dependent on stable coolant supply |

#### Where to Buy
– **asicminermarket.com**: $8,200 USD (as you noted; check for bundles with coolant kit). (Note: Site focuses on ASIC deals; verify stock via contact.)

– **Official**: ElphaPex.com (specs only; sales via partners). Avoid shady resellers—stick to verified for warranty.

#### Related Models
For comparison in the ElphaPex lineup:
– **DG2 18G (Air-Cooled)**: 18 GH/s @ 3520–3960W (~$3,000; louder but cheaper).
– **DG1+**: 14.4 GH/s @ 3950W (entry-level air-cooled, $2,000).
– **DG Home 1**: 2.1 GH/s @ 630W (compact hydro variant for beginners, $600–$800).

#### Tips for Setup
1. **Coolant Prep**: Use distilled water + manufacturer additive; prime the loop before first run to avoid air bubbles.
2. **Pool Setup**: Connect to Scrypt pools like ViaBTC for DOGE/LTC merged mining.
3. **Safety**: Install in a cool, ventilated space; use a surge protector. Monitor via software like Awesome Miner.
4. **Legality/ROI**: Check local energy regs (e.g., EU caps on high-draw devices). If DOGE dips below $0.15, pivot to LTC.
5. **Maintenance**: Clean coolant filters monthly; expect 3–5 year lifespan with proper care.
