BREWERIES AND CELLAR COOLING
persistently serving warm beer, and the role which keeping drinks at the right temperature plays in building an outlet’s reputation for excellence, incorporating cellar cooling technology should be high on the list of what to include in any refi t scheme.
Save your energy
While a warm pint is likely to have drinkers voting with their feet, an ineffi cient cellar cooling system can also be costly in terms of energy usage. Over-cooling an outlet’s cellar by just 1°C can increase energy costs by around 10%, making it an expensive oversight.
The latest generation of cooling systems can
be confi gured to the exact requirements of a pub, hotel or restaurant. The size and layout of the individual cellar is taken into consideration to produce a bespoke system that will ensure a consistent temperature, no matter how warm or cold the weather outside.
Energy consumption is always a potential area to review. Additional devices are available that can be installed to monitor cooler energy use and ensure that costs are kept to a minimum. Innserve’s InnEnergy device, for example, can be installed onto coolers and ice makers, where it
‘learns’ the pattern of energy usage. After an assessment period, the device is programmed with the opening hours of an establishment and is able to optimise the cooler’s energy consumption while saving up to 35% on electricity bills, as well as reducing carbon emissions.
Another important consideration is the location of cooling equipment. The system should be out of the out of the way, to limit space intrusion and maximise effi ciency, as coolers work more effi ciently when air can circulate, yet easy to reach in order for routine cleaning and servicing to be carried out. Grills should be kept free from debris and the water bath topped up regularly, to reach the level of the overfl ow.
F-Gas compliance
Cooler maintenance is an essential element of F-Gas compliance. The latest regulations, introduced in January 2015, require cooling systems over a certain size to be fi tted with a gas leak detector, while smaller systems must be inspected at regular intervals.
If gas does escape, the repercussions can be wide-reaching, with regard to both employee health and legislation. Prolonged exposure
to refrigerant can lead to symptoms such as irritation of the throat, eyes and skin, frostbite, and chemical burns, as well as more severe symptoms like lung and brain damage. Gas leaks also have a day-to-day impact on a company’s bottom line. Equipment must work harder to remain at the correct temperature, using increasingly large amounts of energy as it does so.
If left unrepaired for three months, a small leak in a typical 300kW refrigeration system could result in increased energy costs of £1,400 – not to mention the bill for the repair when it is identifi ed.
While the responsibility for F-Gas compliance
lies fi rmly with cooler equipment operators, some system providers will off er support to licensees and retailers.
This includes checking refrigerant use and volume, conducting an annual leak test and preventative planned maintenance to comply with regulations within the required dates. Innserve, for example will record and manage all inspection activity, including volumes of refrigerant added to systems, and provide maintenance support for customers who install its InnChill device.
