8007 BTUH @ 60°F.

CellarPro's AH8500Sx ducted cooling units (1 Ton Nominal) are suitable for wine cellars up to 2,500 cubic feet in both commercial and residential wine cellars. This ducted unit uses 10-inch ducting and requires insulated ducting on the cold side. The 2,500 cubic feet cellar size assumes that the cellar is constructed with insulation of R19 or better in all walls and ceiling (ie no glass or uninsulated concrete), a setpoint of 55°F inside the cellar and ambient temperatures up to 85°F outside the cellar. Ducting wil add additional load and should be considered in the sizing calculation.

Performance testing shows that this unit maintains optimal cellar temperature and humidity conditions in extreme conditions up to 110°F more effectively than similar units from competing brands. AH8500Sx units also are quieter than comparable units from other brands.

CellarPro AH8500Sx Cooling Unit (P/N 7110). CellarPro engineered the AH8500Sx ducted cooling system to provide maximum cooling power and adjustable humidity control for cellars up to 2,500 cubic feet with the condensing unit located in an exterior environment. The evaporator and the condensing unit each can be ducted up to 100 equivalent feet (50 equivalent feet per duct.) As a split system, the evaporator can be separated from the condensing unit up to 100 feet, allowing the noise and heat from the condensing unit to be located away from interior living areas. The AH8500Sx includes a variable-speed fan on the evaporator with a low setting for quieter operation and a high setting for maximum power.

Frequently Asked Questions

What's the difference between a split system and "through the wall" or "self-contained" systems?

A: Split systems are "split" into two parts: the cold side (evaporator) which usually is installed inside the cellar, and the hot side (condensing unit) which is installed away from the cellar. The benefit of having this split is that the heat and noise from the condensing unit can be located far away from living spaces where it won't interfere with day-to-day life.

Are split systems more difficult to install than self-contained systems?

A: Yes. Split systems require installation by a licensed HVAC technician, whereas a self-contained unit can be mounted through-the-wall and is shipped fully charged and operational out of the box.

What's the difference between valve control and electronic control? Which is better?

A: The biggest difference between valve and electronic control is that, with electronic control, the condensing unit receives power directly from the evaporator, whereas with vavle control, the condensing unit is independently powered, and turns on/off based on the solenoid valve. Valve control is more common in the industry, and benefits from not having to run a power line from the evaporator to the condensing unit, but cannot operate in temperatures below 0°F. Electronic control offers more precision, and allows the condensing unit to be placed in temperatures down to -20°F (with the addition of a compressor heater and fan cycling switch.)

Can I install the entire unit inside the cellar?

A: No, the condensing unit must be located outside the cellar.

If I don't have sufficient space around the condensing unit, is that Ok?

A: The condensing unit generates hot air that must have sufficient space to dissipate, otherwise the unit will recycle its own hot air. The condensing unit cannot be ducted; it requires 12 inches of unobstructed space in front of the coils, and requires approx. 600-700 CFM of ventilation when installed in a confined space.

Does the evaporator include flare connections, or will I need to braze the connections to the line-set?

A: Flare connections are much more prone to leaks, and have been phased out over the years, replaced by fully-brazed connections. This is driven by the EPA and the focus on minimizing refrigerant leaks into the atmosphere.

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 30°F 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.
