Important Glass Door Bar Fridge Information and Facts
There is often numerous pieces of knowledge that are critical when selecting the appropriate refrigerator for the task at hand. This section hopefully answers most of the curly technical questions that you may have! If you can't find your answer here, then its best to give us a call, or download the "Buyers Guide" in 'links' at bottom of page.
Q. Can I use these bar fridges outside in my outdoor entertaining area?
A. Yes, if rated T (Tropical 43oC) or ST (Sub Tropical 38oC), fridges are fine to be located outside, undercover, away from sunlight. N (Standard) rated units only will work in max 32oC Ambient, and that will be chewing up the energy, may not get to the coldest temp and will shorten life from excess runtimes.
There are many variables that will effect the 'performance' (pull down rated, chilling, energy consumption) of the fridge.
- Direct Sunlight will definately impede fridge performance, it is recommended that the unit be in a covered area and in no way in contact with sunlight or other variables that will heat up the area in which fridge is to perform. Glass door fridges work much harder than a normal domestic fridge, especially when your desired temperature is quite low for beer chilling, say 2 degrees Celcius.
- Ventilation, most of these fridges require minimal ventilation, the underbench Rhino and Schmick styles have a system where they are vented from the front, so fitting snugly inside a cabinet is what they have been designed for, there is a massive difference between 100% built in and 'semi built in', it's important to make sure you don't purchase a unit in error as a lot of companies don't give this information, or give misleading information in regard to building in. All units, built in or not will work at the start, but within 3-6 months if you have a unit 'built in' that isn't a proper designed fridge you will start to have a lot of problems due to overheating and extended running times, not to mention uo to 6 times the energy consumption.
Always allow a minimum of 40mm at the rear of units (the power cord needs this minimum space to flex), approximately 10mm on top, and 10mm at each side to allow doors to open where they hinge.
Non Front Venting units require air to circulate so that when warm air is vented from the front it can easily rise and clear away from the unit rather than being sucked back into the cool air inlet. Failure to provide adequate ventilation will make a fridge work harder, lower its life expectancy, and increase your energy consumption.
- Ambient Temperature, this is the actual temperature of the outside air in the area where the fridge is located. All our units are tested between 32oC >and 43oC ambient, however this is just a test, and the units have to work extra hard in this environment. When ambient temperatures exceed 30oC it takes far longer for the units to get to the set temperature - so if you were planning to have a party and knew it was going to be an extra hot day, then it would be best to fill the fridge the night before and get as many cold ones happening as possible. Adding warm drinks during the day take longer to CHILL - especially when the door(s) are being opened and closed repeatedly by many people. The Rhino GSP range are the most energy efficient and well performed built in alfresco units in the world, and work and chill well in 40oC+.
- Condensation in Humid Areas is quite normal for glass door fridges. The higher the relative humidity (RH) the more likely that condensation will form on the outside of glass doors. Even if the ambient temperature is mild at 25oC, the humidity can be 80%, meaning that doors will still have low levels of condensation. Super hot days in conjunction with high levels of relative humidty bring large levels of condensation to glass doors - similar to windscreens in vehicles. Bar Fridges Australia has combatted condensation with 2 features, and now over 70% of our range now has one or both of the following;
1. LOW E Glass - This reflects heat rays up to 70% better than normal glass and really helps with condensation issues. We get LOW E glass on all our units wherever possible, usually double panes. Testing shows that condensation begins to form when Relative Humidity is over 75% with double Low E Glass. If no Low E glass water can form in 50% humidity.
2. Heated Glass - This is where glass is actually electrically heated. By warming the glass to the appropriate level we stop condesation in its tracks. This is an expensive part of the fridge design, and therefore it is only available on a few select models.
All commercial style fridges make noise. The level of noise and what is perceived as 'noisy' will vary with the individual. Basically most commercial under counter 1,2 & 3 door models run at a DB of between 45 and 55. A small domestic fridge runs at around 36DB to give a comparison of actual noise.
The compressor cuts in and out as the fridge goes through the normal operation of running, and it is not unusual for a compressor to turn on/off up to 10 times per hour. Some models are geared with a different cooling set up and therefore make less noise, smaller units (98 litre and less) use 'cold plate' style cooling and fans like a domestic fridge. Larger units (especially full commercial) make use of copper condensors and heavy duty fans to distribute cool air around the cabinet and get rid of the excess heat all for optimum performance.
We are constantly looking for ways to lessen noise in regards to fans used, design and development of sound diversion techniques. We now have fan 'upgrades' available for applications where noise is considered a factor, we have a range of special virtually 'silent' fans we have sourced that can be fitted to most of our models. As these fans dont move as much air volume it means that generally we only do this upgrade to units that will be indoors or outside fully enclosed alfresco area's.
Our range of wine and beer models use 12V fans and are designed especially to reduce noise for domestic, office, and indoor applications whilst still delivering semi-commercial performance. You will still hear the fridges running, but no where near the noise levels of our full commercial units that are generally utilised in hotels, clubs, and pubs. Wherever tranquility and performance is desired we reccommend the use of fridges from the Schmick range.
Did you know
- That a fridge works and chills much better with it is full of product. The reason is that the fridge has to only chill about 25% of the air volume of what it would have to chill if the fridge was empty. When first starting a new fridge, it's best to load it up and let it run flat out for 24Hours. This effectively runs it in, and it will settle into its normal operation. All fridges should NOT BE TURNED ON for a minimum of two hours after rellocation, transport, or moving. Oil in the compressor will be relocated to the walls of narrow ducts and needs to find its way back before operation. Failure to let a fridge "settle" can result in compressor failure and an expensive repair which is not covered under warranty.
- All our units have the whole chilling system in-built within the fridge, fully portable. Whereas most pubs and clubs have previously ran fridges with giant remote compressors, running numerous units with one system. The problem is if these compressors fail it means that all of the fridges at that venue are vulnerable, whereas with these units being self contained it limits a problem to that single unit. It also makes placement so much easier with no piping that needs to be ran to the remote compressor.
- That a thermostat control in most commercial fridges has a variance of 5oC, this means that if you set unit to be 2oC, it will turn OFF at 2oC, but will need to get to 7oC before it starts up again. Now if you have an electronic display and see 7oC naturally you will panic, but it's perfectly normal as the temperature probe is measuring the air temperature, and not the temperature of your drinks. In a nutshell without being too scientific, the air temp may get to 9, but the drinks will only have raised 1-2oC from when fridge turned off, so they will only need a little tickle up to be back to 2oC.
GSP Rhino Green Sense Plus Range
- We have basically taken all the knowledge we have gained sinced opening our doors and in dealing with 15 different factories to produce the world's most economical and well performed outdoor alfresco glass door fridges;
1. Sourcing and gaining supply with the best brand name companies so that we can fit the highest quality parts in the world into the fridges
2. A patented 'air flow' design that will allow these units to work at minimum energy levels, coolng quicker and using less energy, compared to our closest rival our units run over 2 times cheaper, thats quite amazing.
3. Parts used, including compressor to be the best energy saving materials on the world market
- One of the most asked questions is how much is it going to cost me. The basic answer is, that a glass door fridge will cost you more than most domestic solid door fridges. Of course the variables are many, set temperature, ambient, amount of openings etc. There are many ways to help save power with most of our fridges, from adjusting parameters on controller, to fitting a timer for periods of non usage when on holidays. We have spent a lot of time and money looking at ways to lessen power consumption and we have implemented all of these with some new ideas to follow. The main things that help are;
- LOW E Glass
- LED Lighting
- Smart controllers like USA CAREL and the Intelligenza range from Rhino saves over 35%)
- Compressors that use 25% less energy and deliver better performance
- EBM (German) fans with very low power requirements, 70% less than similar
In publicly available information on the MEPS site, you can compare other brands with the Rhino GSP units. A quick comparison is the with units sold in Harvey Norman.
MEPS Publicly available information:
Brand Sold in Harvey Norman:
C1 13.60Kw/24hours/m2 5M2
C2 10.54 5M2
C3 10.31 5M2
GSP1 4.63 5M1
GSP2 4.46 5M1
GSP3 4.16 5M1
Conclusions to draw from above data.
Energy Efficiency: Rhino cabinets more than double the efficiency
Cooling Performance: Rhino cabinets chill more effectively (M1 means the warmest bottle was not more than 5C in the test. M2 means the warmest bottle was up to 7C during the test)
The MEPS figure compares energy consumption with the glass area, hence the GSP3 appears to be more efficient than a GSP1. The actual energy consumption during the test (data not visible on the MEPS site) is:
GSP1 1.25 kw / 24 hrs
GSP2 1.65 Kw / 24 hrs
GSP3 2.29 kw / 24 hrs
If you press the Eco button, the temperature inside the cabinet works between 4-10C and this will save approx. 30% energy. Press the Eco button again and in about 2 hours it will return the drinks to serve temperature of 1C. There is no other cabinet on the Australian market than matches the GSP for performance or efficiency.
There are two types of wine fridges on the Australian market, compressor driven and 'Peltier' which is also known as Thermo Electric Cooling. Both cooling systems are completely different and both have certain advantages over the other.
Naturally compressor cooling is more expensive as this is a proper refrigerated style that can be set to any temperature, and then hold at that temperature no matter what ambient temperature is. With the 'Peltier' style it works on what temperature the ambient is around the unit, and it has a maximum decrease of usually between 14 and 18oC from the room temperature depending on the setting. So if ambient was 30oC and your unit was set on 12oC, the max might be 15 under ambient, so best it can do in 30oC is 15oC, and this goes up with each degree above 30oC.
Our range of compressor driven units is now very stable, after 6 years of trial and error and identifying problems and fixing we now can place products confidentally into the market.
We invite you to compare the Schmick range of wine and beer refrigerators against all other brands, we have done everything possible to match or better the products on the market at the moment.
