Question 1: Is there a difference between a compact refrigerator and an undercounter refrigerator?

Question 2: How does an auto cycle defrost system work?
Question 3: How long can I keep draft beer?
Question 4: How much beer is in a half keg?
Question 5: How long does a CO-2 cylinder last for dispensing draft beer?
Question 6: Where is the appropriate place to store wine?
Question 7: What are the correct temperatures and proper methods to store fine wines?

Answer 1: There certainly is. A compact refrigerator has condenser coils on the back, which prevent it from being placed flush against a wall. There must be space for ventilation at the back and top for heat from the coils to escape.

If you surround a compact refrigerator with cabinets and countertop, you must allow two inches of clearance behind it—and cut a slot in the countertop above the condenser coils for ventilation. The resulting look, with gaps around the refrigerator and a slot in the countertop, is simply unacceptable in most applications, and most definitely in high-end designs.

An undercounter refrigerator, on the other hand, has a refrigeration system which exhausts its hot air through a grille on the front of the refrigerator. This type of system is called “forced air ventilation” There are no condenser coils on the back, so the refrigerator can be pushed up tight against a wall. Cabinets and countertop can be flush with the refrigerator’s cabinet side and top. No additional clearance for ventilation is needed (hence the often-used term “zero clearance”).

All Marvel® undercounter refrigerators can be built in with zero clearance (i.e., no clearance required at the back, top, or sides). Choose Marvel refrigeration products whenever a true undercounter, built-in product is needed.

Answer 2: Auto cycle defrost is not as complicated as it sounds. In fact, cycle defrost systems are the least complex—and most effective—defrost systems available.

Cycle defrost systems are feasible only on all-refrigerator models because they lack a freezer compartment.

Cycle defrost units contain a special thermostat which senses the evaporator plate temperature. At the completion of each compressor cycle, the thermostat disconnects the electrical power and turns off the compressor. The thermostat will not connect the electrical power again to initiate the next compressor run cycle until the evaporator plate reaches a preset temperature, well above freezing.

During this evaporator warm-up period, the frost which has accumulated during the previous compressor cycle melts and becomes water droplets. These droplets run down the vertical surface of the evaporator and into the drip tray just underneath it, which then empties into a drain tube.

The drain tube discharges the water droplets into the condensation pan located in the mechanical assembly under and outside the refrigerator compartment. There, the heat from the compressor, as well as the air flow from the condenser fan, evaporate the moisture.

Answer 3: Draft beer is not pasteurized, so it must be kept cold, preferably at 38°F. Temperatures above 45°F may cause the beer to become wild, turning sour and cloudy. Draft beer should be consumed within 30 days; since it’s not pasteurized, it loses more and more of its original brewery-fresh taste and aroma the older it gets.

The Marvel® 61HK Beer Dispenser allows you to keep your beer as cold as 33°F. (You may choose a warmer temperature if you prefer.) Serving draft beer is convenient and fun with a Marvel® Beer Dispenser—so you should have no problem emptying a keg before it loses its taste!

Answer 4:
• 1/2 barrel of beer contains approximately 15 gallons or 1,984 fluid ounces
• 1/2 barrel of beer equals approximately 7 cases of 12-ounce bottles or cans
• 1/2 barrel of beer contains approximately 192 12-ounce glasses with a 1" head on top
• 1/4 barrel of beer contains approximately 8 gallons of beer
• 1/4 barrel of beer equals approximately 3 cases of 12-ounce bottles or cans Marvel's 61HK Beer Dispenser will hold either a 1/2 or 1/4 keg.

Answer 5:
• It takes about a half-pound of CO2 to dispense a half-barrel of beer.
• A 2-1/2 lb. CO2 cylinder should dispense between four and five half-barrels, or eight to ten quarter-barrels.
• A five-pound CO2 cylinder (such as the one found in the Marvel® 61HK) should dispense eight to ten half-barrels, or 18 to 20 quarter barrels.

Answer 6: Just remember four key words to wine storage:
Darkness - very little or no light at all
Stillness - no sounds or vibrations
Coolness - temperatures between 50 and 60°F
Humidity - between 50 and 80% humidity

Answer 7: Bottles should be kept on their sides to keep corks moist.

Fifty-five degrees Fahrenheit is the most commonly recommended storage temperature. More important than mere temperature, however, is temperature consistency, keeping the wine within the range of 50° and 60°F.

Marvel® Wine Grottos™ and Beverage Centers create a stable environment for wine storage, free from excessive vibration and light. Consistent humidity and temperature both protect and enhance the maturation of fine wines. Wine racks cradle bottles at the proper inclination to keep corks moist.
