Transtherm Dbl Castel Glass Blk Full Shelf #17043
Details
When a collection reaches the point where a single-zone cooler can no longer separate long-term aging from bottles ready to serve, the Double Castel earns serious consideration. Two independent Castel units share one freestanding enclosure, each with its own digital thermostat and three temperature zones: one large compartment for aging and two smaller sections dedicated to chilling whites and sparkling wine. Made in France by Eurocave, it holds 330 bottles as configured and scales to 418 at maximum capacity.
The engineering is built around precision and stability. Compressors are physically disassociated from the cabinet body, keeping vibration off your bottles entirely. Temperature variation is held within 2–3°F, and the thermal pump actively manages humidity between 55% and 80% without requiring a separate humidifier. The integrated heating element means this cabinet operates in unconditioned spaces ranging from 32 to 95°F, making it a realistic option for a finished basement, detached garage or a second home that sees significant seasonal swings.
Each side ships with 10 adjustable rolling shelves holding 12 bottles each, plus a half shelf on the bottom. The shelves roll out on low-profile grooves that accommodate Bordeaux, Burgundy and larger-format bottles without modification. Silent operation at 37 dBA makes this a workable fit in a dining room or open living space.
Best For
- Running one side for long-term red storage while keeping whites and Champagne properly chilled on the other at the same time
- Installing in an unconditioned basement or garage where ambient temperatures vary considerably across seasons
- Storing a mixed collection of varied bottle shapes where rolling shelves need to handle Bordeaux and Burgundy profiles interchangeably
- Consolidating 300+ bottles into a single freestanding unit without sacrificing temperature independence between zones
Features
- Vibration isolation: Compressors are mounted independently from the cabinet body and run at slow, balanced speeds. This matters for long-term aging — sustained vibration agitates sediment and can interfere with proper bottle development over years.
- Temperature precision: The electronic regulation system holds internal variation to a maximum of 2–3°F. Each side has its own digital thermostat, so you can run one side for long-term storage and the other at serving temperature simultaneously.
- Thermal pump (Transtherm exclusive): Recycles condensation internally rather than expelling it, which actively maintains humidity between 55% and 80%. Most cabinets only manage excess humidity — this one can also raise it by adding water to the system.
- Heating element included: Unlike cooling-only units, this cabinet can actively heat as well as cool, making it suitable for uninsulated garages, basements or seasonal homes where ambient temperatures may drop below typical wine storage range.
- Rolling shelves with low-profile grooves: Each of the 10 adjustable shelves per side accommodates mixed bottle shapes — Bordeaux, Burgundy and Champagne formats — without reconfiguration. Shelves roll out fully for access to bottles at the back.
- Aluminum interior: Interior lining was upgraded from thermoformed polystyrene to aluminum, which is more durable and easier to clean over the long term.
- 4.5cm high-density foam insulation in the cabinet walls and door.
- Silent operation rated at 37 dBA — quiet enough for dining room or living area placement.
- Multiple alarms cover both temperature excursions and humidity levels.
- Removable door handle (steel and aluminum); door is reversible for left- or right-hand swing to suit your installation.
- Made in France by Eurocave.

What These Specs Mean
- 2 x 15-Amp Dedicated Circuits: Because each cabinet runs independently, the Double Castel requires two separate dedicated circuits — plan for this in advance if the installation location does not already have two available circuits.
FAQs
Is this cabinet freestanding or can it be built in?
A: The Double Castel is a freestanding unit. It requires 3 inches of clearance behind and 2 inches on the sides and above for proper ventilation. It is not rated for built-in installation. At 53½" wide x 27¼" deep x 72" tall and 504 lbs, placement and floor load planning are essential before delivery.
What are the electrical requirements for the Double Castel?
A: Because this is two independent Castel units joined side-by-side, it requires two dedicated 15-amp circuits running at 120V / 60Hz. Each cabinet draws its own circuit — a single shared circuit is not sufficient. If your intended location only has one outlet, electrical work will be needed before installation.
How many bottles does it actually hold, and does shelf configuration affect that?
A: As configured with the fully shelved setup, the cabinet holds 330 bottles total (165 per side), using 10 rolling shelves at 12 bottles each plus one half shelf per side. The shelves are adjustable, and if you reconfigure to maximize bulk storage, the maximum capacity climbs to 418 bottles (209 per side). The rolling shelves have low-profile grooves designed to accommodate different bottle shapes, including broader Burgundy-style bottles alongside standard Bordeaux.
How does Transtherm handle temperature variation and vibration — two things that matter most for long-term cellaring?
A: The electronic temperature regulation system holds variation to a maximum of 2–3°F inside the cabinet. Vibration is controlled through slow, balanced compressors that are physically decoupled from the cabinet body — not simply padded, but mechanically isolated. Noise is rated at 37 dBA, quiet enough for a dining room or living space. The thermal pump — a Transtherm exclusive — recycles condensation and keeps humidity between 55% and 80%, which protects corks over long aging periods.
Can this cabinet operate in an unconditioned garage or basement that gets very cold in winter?
A: Yes. The integrated heating element is specifically designed for this use case. The Double Castel can operate in ambient environments ranging from 32°F to 95°F (0–35°C), which means it both cools and heats as needed to maintain your set temperature. Most wine coolers only cool, making them unusable in spaces that drop below the target storage temperature in winter. This cabinet's heating capability is a key differentiator for unheated spaces.
What does the warranty cover on the Double Castel?
A: The cabinet carries a 1-year limited warranty covering parts and labor, plus a separate 5-year limited warranty on the compressor. The two-tier structure is standard for Transtherm — the compressor warranty is particularly relevant given that the compressor is the most expensive component to replace and the one most likely to be stressed by continuous operation in variable ambient conditions.
