The Wine Guardian TTW018 is discontinued and cannot be ordered. Wine Guardian has ended production of this model and states on its own TTW018 product page that the unit "is being replaced with the TTW02B Sentinel unit". This page is kept as a specification and service record for owners of installed units. If you are choosing a through-the-wall unit today, the current model is the Wine Guardian TTW02B Sentinel.

The Wine Guardian TTW018 is a discontinued self-contained through-the-wall wine cellar cooling unit that Wine Guardian publishes at 981 to 1,950 BTU for cellars of 100 to 1,200 cubic feet.
Wine Guardian has phased the model out and states on its own TTW018 product page that the unit "is being replaced with the TTW02B Sentinel unit". The TTW018 is not sold on this page and cannot be ordered. If you are researching a TTW018 you already own, this page is the specification and service record; if you are choosing a through-the-wall unit today, the current model is the TTW02B, built in Classic, Sentinel and Defender trims.
Two figures circulate for this model and only one of them is current. Wine Guardian's live product page lists 981 to 1,950 BTU and 100 to 1,200 cubic feet; an older Through-the-Wall datasheet listed 2,100 BTU/h, and several retailer listings still repeat it. We publish the manufacturer's current product-page figures. As an authorized Wine Guardian dealer we can help an owner identify the right current model, and final sizing should be confirmed with a licensed HVAC professional.
The TTW018 used the same self-contained through-the-wall format that Wine Guardian still builds today, so this walkthrough of the line explains how the format conditions a cellar without ductwork.

Wine Guardian's own TTW018 product page states that it is phasing out the 09 and 18 through-the-wall units and that this unit "is being replaced with the TTW02B Sentinel unit". The TTW02B Sentinel is therefore the model Wine Guardian itself names as the replacement. Sentinel, Classic and Defender are three trims of that same successor platform: Classic is the build without the humidity sensor, and Defender adds the ultra-quiet and exterior-wall packages. Compare the three before deciding which one matches an existing TTW018 installation.
The TTW018 is not the right choice for any new installation, because Wine Guardian no longer produces it. It remains the correct reference for a cellar that already runs one. If that installed unit is running but no longer holding its set point, the causes to check in order when a cellar stops holding temperature covers what an owner can rule out and where a technician takes over.
The TTW018 was a single-chassis through-the-wall cooling unit that Wine Guardian positioned for smaller wine cellars and wine cabinets and described as installable without a contractor. Every figure below comes from Wine Guardian's current TTW018 product page.
| Feature | What it meant for your cellar |
|---|---|
| Through-the-wall, ductless design | Mounted in a wall opening and exhausted into an adjacent conditioned space, with no ductwork and no remote condenser to place. |
| Self-contained chassis | Evaporator and condenser sections sat in one 25 in by 14.25 in by 15.88 in chassis weighing 62 lb, so the opening and the unit were sized together. |
| Small-cellar capacity | Wine Guardian publishes 981 to 1,950 BTU and a 100 to 1,200 cubic foot range, which places the TTW018 in the small-cellar band rather than the mid-size band. |
| Standard 115V plug-in power | 115V single-phase 60 Hz on a Plug Type B cord, so no dedicated high-voltage circuit was specified by the manufacturer. |
| Owner-installable format | Wine Guardian describes the unit as one that can be installed without the support of a contractor, though exhaust space and electrical still need professional confirmation. |
| Superseded by the TTW02B | Wine Guardian names the TTW02B Sentinel as the replacement, which adds Bluetooth and NFC controls, a published sound rating and humidity sensing. |
Note on sources. Wine Guardian's current product page is the primary source for every TTW018 figure on this page. Where an older datasheet disagrees, the current product page wins.
Wine Guardian does not publish a sound rating for the TTW018 on its current product page, so this page states no dBA figure for it. The current through-the-wall units it was replaced by do carry published ratings, measured on the evaporator side, and those are shown below for reference.
Ratings are Wine Guardian's published evaporator-side figures for the current TTW02B trims. Perceived loudness in a finished room also depends on wall construction, the exhaust space and how the opening is sealed.
Wine Guardian publishes the TTW018 at 981 to 1,950 BTU for cellars of 100 to 1,200 cubic feet, in a 62 lb chassis on 115V power. The full published record follows.
These Wine Guardian through-the-wall parts are listed for owners keeping an already installed TTW018 in service, not as an upgrade path for a unit Wine Guardian no longer builds. Part numbers were revised when the through-the-wall line changed over, so confirm compatibility with Wine Guardian against your unit's serial number before ordering anything for a TTW018. For the servicing cadence itself, a maintenance checklist with every task, tool and interval sets out what a through-the-wall unit needs and how often.
Warranty and service. Wine Guardian's standard warranty runs 25 months on parts and 13 months on labor from the original invoice date. Wine Guardian's Platinum warranty runs 25 months on parts and 25 months on labor, plus a 36-month parts-only extension on the compressor, evaporator coil and condenser coil, which carries those three components to 61 months in total. Warranty, parts supply and service for Wine Guardian equipment run through Wine Guardian; both warranty documents are linked below, and an owner should confirm remaining coverage with the manufacturer against the original invoice date.
The TTW02B is the current version of the same through-the-wall format, and it differs from the TTW018 on availability, published capacity, chassis depth and how Wine Guardian sizes it. Each figure below is Wine Guardian's own published data for that model.
| Decision factor | TTW018 (discontinued) | TTW02B (current) |
|---|---|---|
| Availability and support | Phased out by Wine Guardian; no longer produced, and parts are limited | In current production in Classic, Sentinel and Defender trims |
| Published cooling capacity | 981 to 1,950 BTU, with no rating condition stated | 2,650 BTU/h nominal at 75°F (Wine Guardian) |
| How the cellar size is given | A published range of 100 to 1,200 ft³ | No cubic-foot range is published; Wine Guardian sizes the B series by heat load |
| Chassis depth and opening | 25 in deep by 14.25 in by 15.88 in | 27.6 in deep by 14.1 in by 15.75 in on the Sentinel trim, so the opening is not a drop-in match |
Best for. Choose the TTW02B if you are buying a through-the-wall unit today or replacing a failed TTW018, because it is the model Wine Guardian currently builds, supports and stocks parts for. The TTW018 is not ideal for any new installation, and this page exists to document the specifications of units already in service. Because the chassis depths differ, have a licensed HVAC professional or qualified contractor confirm the rough opening, exhaust space and electrical before ordering a replacement.
