Self Contained 1/4 Ton 1800H-HE Houdini #37402

CellarPro 1800H-HE Houdini Cooling Unit (P/N 37402). CellarPro engineered the 1800H-HE Houdini specifically for shallow-depth glass wine cellars, combining a low-profile design with an upgraded low-GWP R-290 compressor, energy-efficient EC fans and longer-lasting aluminum coils.

Just 10 1/2 inches deep and 10 inches tall, the 1800H-HE Houdini cooling unit is designed to “disappear” inside — or atop — the cellar. Dual independent variable-speed EC fans offer flexibility to balance quiet operation with maximum cooling performance.

All air-cooled refrigeration equipment requires fresh air intake to dissipate the heat generated by the cooling unit. The fresh air intake cannot come from the wine cellar space — it must come from space outside the cellar.

CellarPro 1800H-HE Houdini wine cooling units deliver 1900 BTUH total / 1505 BTUH sensible capacity at 55F, providing 1/4-ton cooling for shallow-depth glass-enclosed wine cellars using appropriate sizing assumptions.* Designed specifically for modern glass wine displays, the 1800H-HE Houdini combines a compact, low-profile design with flexible airflow configurations, making it ideal for installations where standard cooling units are too deep or visually intrusive. This upgraded HE model features a powerful low-GWP compressor, upgraded EC fans, longer-lasting aluminum coils and robust components engineered for demanding glass-cellar installations.

Just 10 1/2 inches deep and 10 inches tall, the 1800H-HE Houdini is designed to sit inside the cellar, atop the cellar, partially in the cellar ceiling or remotely from the cellar with approved ducting. Dual independent variable-speed EC fans provide flexibility to balance quiet operation with maximum cooling performance.

For example, using the following assumptions, the 1800H-HE Houdini would be sized appropriately for the following applications*:

• Proper construction with a vapor barrier,
• R13 insulation in the non-glass walls, ceiling and floor,
• 75F ambient temperature surrounding the cellar, and
• No ducting

*Glass-enclosed wine cellars require careful sizing based on glass area, glass type, ambient conditions, insulation, target cellar temperature and airflow configuration. Deviation from these assumptions should be evaluated using our online Wine Cellar Cooling Calculator.

Compatibility & Replacement Guide

The 1800H-HE Houdini is an upgraded replacement for:

• CellarPro 1800H-ECX Houdini

The 1800H-HE Houdini cooling unit is a strong upgrade for customers seeking:

Installation Requirements

For optimum performance and warranty coverage, the 1800H-HE Houdini must be installed in a properly insulated, airtight wine cellar with a vapor barrier. Glass-enclosed cellars require special attention to glass type, total glass area, insulation, ambient temperature and target cellar temperature.

Recommended conditions and sizing assumptions:

• Properly insulated, airtight construction with vapor barrier
• Correctly sized glass area based on cellar dimensions, glass type and target cellar temperature
• Ambient temperature evaluated based on the installation location
• Fresh air intake must come from outside the wine cellar
• Deviation from these assumptions should be evaluated using our online Wine Cellar Cooling Calculator

• With an auxiliary inline fan, the hot side supports up to 100 equivalent feet, 50 feet per duct
• High fan speed is required for ducted installations
• Auxiliary fans should never be used on the cold side
• CellarPro OEM duct hoods must be used for ducted installations, otherwise warranty coverage will be voided

Configuration Options

• Shallow height and depth: 10 1/2 inches deep x 10 inches high x 36 1/2 inches wide

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 do I pick between this unit and the 1800XTS?

A: This cooling unit and the 1800XTS provide the same BTUH output, and therefore can be used to cool wine cellars with similar thermal loads. The biggest difference is that the 1800XTS was designed - and works best - when installed through-the wall, with the front 8 inches of the cooling unit inside the wine cellar. Also, the cold side of the 1800XTS cannot be ducted unless the cooling unit is located directly above the cellar. In contrast, the 1800H-ECX cooling unit was designed for shallow-depth installations, inside or atop the cellar. In addition, the 1800H-ECX can be placed up to 50 equivalent feet away from the wine cellar and ducted. Other differences include an advanced condensate management system in the 1800H-ECX, which has a large stainless steel drain pan and 100W condensate evaporator, as well as variable-speed fan control and removable power cord in the 1800H-ECX cooling unit.

How cold can the temperature be where the cooling unit pulls air?

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)

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 ducted up to 50 equivalent feet away from the wine cellar when used with our cold-side (front) duct hoods and kits. Remember that cold-side ducting must be insulated and additional load should be added to properly size the required cooling unit.

Can I install the entire unit inside the cellar?

A: These cooling units can be installed completely inside the wine cellar, attached to the ceiling, with the hot air exhaust and fresh air intake pushed to and pulled from the space above the cellar.

If I don't have sufficient space to pull fresh air, is that Ok?

A: The hot side of the cooling unit generates hot air that must have sufficient space to dissipate, otherwise the unit will recycle its own hot air. The hot air exhaust and/or intake can be ducted to another location with our hot-side duct hoods and kits, which allow supply and return airflows to be redirected to and from a temperature controlled environment OUTSIDE the cellar.

Can I use the low fan speed setting on the cooling unit when the unit is ducted?

A: Duct hoods and kits create additional static pressure and therefore require the use of the high fan speed to overcome the additional static pressure.

Do I need the condensate drain line?

A: If you are using the cooling unit in an airtight cabinet or cellar, you probably don't need the drain line. To the extent that condensate is created, the 100W heating element inside the cooling unit reduces drainage as it helps to burns off condensate before it reaches the drain line. However, if your cabinet/cellar was built without a vapor barrier, or there are gaps where the door(s) closes against the cellar, you will need the drain line to allow excess condensate a path to be released to a designated location.
