Self Contained 1/4 Ton 1800XTS-HE #37164

1925 TOTAL / 1602 SENSIBLE BTUH @ 55F.
CellarPro 1800XTS-HE Cooling Unit (P/N 37164). The 1800XTS-HE is built to deliver maximum cooling power in its class, providing 1/4-ton cooling for small wine cellars up to 400 cubic feet under standard sizing assumptions (no glass, 85F ambient and R-19 insulation throughout). With an R-290 compressor, EC fans and aluminum evaporator coils, it delivers powerful performance with efficient airflow, reduced environmental impact and energy-saving components.

CellarPro engineered the 1800XTS-HE for customers who want the most cooling capacity in a compact, cellar-friendly footprint. With a wide 47F–62F setpoint range and adjustable humidity control, it helps protect cork integrity and wine labels in properly designed wine cellars.

All air-cooled refrigeration equipment requires a source of fresh air to dissipate heat. The fresh air intake must come from outside the wine cellar and cannot be drawn from the cellar space.

Designed for indoor use only, 1800XTS-HE units can operate in ambient conditions from 40F to 95F out of the box with a plug-in design. For operation in colder environments, see the Options & Upgrades tab for recommended modifications.

What is "Sensible BTUH"?

A: You should always use Sensible BTUH* when comparing different brands of cooling units, and when sizing a cooling unit for your wine cellar. Every cooling unit produces a certain amount of Total BTUH, which is the sum of Sensible BTUH (lowers the temperature) and Latent BTUH (lowers the relative humidity). Because our goal is to cool wine cellars while preserving humidity, wine cellar cooling units should have high Sensible BTUH and low Latent BTUH. The relationship between Sensible and Latent BTUHs is know as SHR (Sensible Heat Ratio), which is calculated as Sensible BTUH/Total BTUH. The SHR for CellarPro cooling units is greater than 90%, which means that CellarPro units provide maximum cooling power without stripping out humidity from the cellar environment.

*CellarPro Sensible BTUHs are calculated assuming 55F cellar temperature, 60% relative humidity and 95F ambient for all units except 1800 units (85F ambient).

How cold can the temperature be where the cooling unit is installed?

A: For installations in environments below 40F down to 20F, we recommend adding our compressor heater (P/N 1727), which is included as standard equipment on all outdoor units. Below 20F, in addition to the compressor heater, we recommend adding our fan cycling switch (P/N 6972)

How do I choose between top exhaust versus rear exhaust? What about the fresh air intake?

The fresh air intake will always come from the rear of the cooling unit, and must pull air from OUTSIDE the wine cellar space - it must never be installed to pull air from inside the cellar. On 1800 Series cooling units, the hot air exhaust can exit from the top or the rear. Choose whichever configuration directs the exhaust to a space that is sufficiently large to accept the exhausted air, as long as the exhaust goes OUTSIDE the cellar and will NOT intermingle with the fresh air intake. If you plan to duct the hot side of the cooling unit, then the hot air will need to exhaust from the rear.

Does the unit really need a dedicated circuit?

A: First, the background. Unlike our competitors, we build our cooling units with precision expansion valves, not cap tubes, which means that our cooling units aren't limited to a 30F differential between the desired cellar temperature and the ambient temperature. Cooling systems with expansion valves are much more precise than cap tubes, and much more sensitive to low voltage conditions, which is why our units require dedicated circuits. When we say "dedicated circuit", we mean that the circuit shouldn't have any items that require heavy draws of electricity - eg other appliances, vacuum cleaners, big-screen TVs, blow-dryers - on the same circuit as the cooling unit. Lighting, computers or other low-draw items shouldn't be a problem on the same circuit.

Can the cooling unit be located in a remote location and ducted to/from the wine cellar?

A: These cooling units can be installed above the wine cellar when used with our front intake hood.

Does the unit need to be installed through the wall, or can I install the entire unit inside the cellar?

A: These cooling units can be installed completely inside the wine cellar when used with our rear duct kit (P/N 1439), which allows rear supply and return airflows from a temperature controlled environment OUTSIDE the cellar to be ducted (with insulated ducting to minimize heat transfer inside the cellar) up to 100 equivalent feet (50 feet per duct).

What if I don't have sufficient space behind the cooling unit for the hot air exhaust to dissipate?

A: The rear of the cooling units can be ducted to another location by using our rear duct kit (P/N 1439), which allows rear supply and return airflows from a temperature controlled environment OUTSIDE the cellar to be ducted up to 100 equivalent feet (50 feet per duct).

Do I need the condensate drain line?

A: If you are using the cooling unit in a sealed cabinet, you probably don't need the drain line. If you are using the cooling unit in a cellar, we recommend the drain line, which can be drained inside (bottom) or outside (rear) the wine cellar. Choose the 100W heating element to reduce drainage as it helps to burns off excess condensate before it reaches the drain line.
