Overview

CellarPro AH4500Si-ECX Cooling Unit (P/N 36293). CellarPro engineered the AH4500Si-ECX ducted cooling system to provide maximum cooling power and adjustable humidity control for cellars up to 1250 cubic feet. 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. Designed for internal installations, the AH4500Si-ECX includes energy-efficient independent variable-speed EC fans with a low setting for quieter operation and a high setting for maximum power.

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.

Details

4328 SENSIBLE BTUH @ 55F.
CellarPro's AH4500Si-ECX ducted cooling units (1/2 Ton Nominal) are engineered for wine cellars up to 1250* cubic feet in both commercial and residential wine cellars. This ducted unit uses 8-inch ducting and requires insulated ducting on the cold side.

This unit maintains optimal cellar temperature and humidity conditions in extreme conditions up to 110F. AH4500Si units use energy-efficient EC fans and are significantly quieter than comparable units from other brands. Visit our Learning Center for data tables, performance charts and product comparisons among different brands.

Our Compressor Heater (P/N 1727) is included to protect the compressor from in temperatures down to 20F. For installation of the condensing unit in environments below 20F down to -20F, our Fan Cycling Switch (P/N 6972) is a required addition, and Electronic Configuration is required.

*Assuming R19 insulation throughout the cellar, 55F inside the cellar and 85F outside the cellar. Cold-side ducting, glass and/or uninsulated walls, extreme humidity, altitude and other factors may affect the sizing calculation.

Our cooling units are designed to be used in properly-constructed wine cellars that are adequately insulated, airtight and sealed with a vapor barrier. In improperly-constructed cellars, the cooling unit will create excess condensation, leading to damage and premature failure of your cooling unit (not covered by warranty).

Configurations

Configurations

  • CellarPro AH4500Si-ECX units are designed to be ducted, with the evaporator near (or inside) the cellar, and the condensing unit in a remote interior location up to 100 feet away.
  • The evaporator and the condensing unit each can be ducted up to 100 Equivalent Feet (50 Feet per Duct) with 8-inch ducting .
  • CellarPro's split configuration allows multiple ducting alternatives, as follows.
    1. Collars or grills for EXHAUST (ie Supply) are located at the front (shown at left), top or rear of the cooling system, and are interchangeable to meet your specific requirement.
    2. Collars or grills for INTAKE (ie Return) are located at each end (left: evaporator, and right: condenser), and include professional-grade air filters to protect the unit.
  • We recommend pulling the fresh air intake (hot-side) from a temperature-controlled environment (must be outside the cellar). If the hot-side exhaust will be directed to a different space than the intake, always make sure that both spaces are sufficiently voluminous so that you don't run into issues with negative pressure.
  • A bottle probe temperature sensor (10' cord) plus your choice of duct collars, indoor grills and blank plates are included in the price of the cooling system.
  • CellarPro Air Handler Split systems offer a choice of 110V / 60Hz wiring and power configurations:
    1. Two permanent power connections for the evaporator (2.0 amps / 15 amp circuit breaker) and the condensing unit (10.7 amps / 15 amp circuit breaker). This wiring configuration is recommended for Valve Control.
    2. One permanent power connection for the entire system (20 amp circuit breaker). In this configuration, the condensing unit must be wired to the evaporator, and must be used with Electronic Control.
    3. The amp data above is not valid when the integrated heater and/or humidifier are configured with the cooling unit - please consult those Owner's Manuals for the additional amps required when using those upgrades.
  • When the control panel is difficult to access, we offer a remote control display kit which is wired to the cooling unit and allows the digital display to be mounted inside or outside the cellar.
  • The condensing unit 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.
  • For installations in environments below 40F, AH4500Si-ECX units require our Compressor Heater (P/N 1727) (included).
  • For installation in environments below 20F down to -20F , Electronic Control is the required configuration, and our Fan-Cycling Switch (P/N 6972) is required in addition to the compressor heater (both sold separately).
  • The evaporator should never be exposed to temperatures below 32F.
  • Access to the left and right side of the evaporator unit is required for installation.
  • All split systems must be installed and charged on site by a qualified HVAC professional. Line-set equivalent feet must be calculated in accordance with ASHRAE guidelines; refer to our Line Sizing Chart for more information.
  • A CellarPro cooling unit must always be used in the upright position, and should never be operated on its side or upside down.

Q&A

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).

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 we do not recommend valve control for installations in temperatures below 30°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.
