  1. Whats the difference between a domestic & commercial fridge?
    Domestic fridges and commercial fridge look similar, but are not. With a domestic fridge, the power of the compressor is designed around the few number of times a domestic fridge door is opened during the day. A quite modestly-powered compressor will be able to cope with the heat loss without food safety risks. The construction of both the cabinet and the motor is only robust enough for light domestic use, so used in a commercial environment, not only do they pose a food safety hazard, they need replacing far more often than commercial fridges, so are not even cost effective.

    With a commercial specification fridge in a busy working kitchen, the door is going to be opened very regularly and probably be exposed to a far hotter kitchen. The compressor needs to be powerful enough to rapidly pull down the internal fridge temperature to replace heat loss.

    Most commercial fridges also incorporate fans which evenly spread the cool air through the cabinet, a feature domestic fridges do not have. Commercial fridges are better insulated, designed for easy cleaning and some are able to electronically record temperatures which can be used as proof of due diligence in food safety procedures should a food poising claim be made.

  2. Why does a standard fridge say its a manual defrost?
    All fridges are automatic defrost, only a larder fridge with an ice box would require manual defrost.

  3. What is the difference between static cooling and fan assisted cooling?
    Static cooling is natural convection of air and relys on the freezing of the back plate or coil, the cold air then falls within the area. To stop a large ice build up the fridges are programmed to defrost, draining off the water then repeating the process again.

    The draw backs are :
    Once the cabinet is on defrost the air temperature will rise, falling again when the process repeats. Seeing the air temperature some customers assume the cabinet to be faulty, which is not the case.
    Upright fridges should not be overstocked with products touching the back place otherwise the products will freeze or reduce the fridge's operation.

    Fan assisted cooling - A fan recirculates cold air within the cabinet which in turn reduces the temperature of food quicker than a static fridge.
    The draw back with fan assisted cooling is : Recirculated air will dry the food out quicker than a static fridge.
    Overstock fridges inhibiting the air flow which affect the cooling time of products.

  4. When moving a fridge can I tilt the fridge on its side?
    Yes - you can carefully tilt a fridge up or even place the fridge on its side.
    You must make sure you place the fridge on the correct side in order not to drain oil out of the compressor into the discharge pipe

    Turn the fridge around, welded to the compressor (motor) there are three different size pipes, two on one side and one on the other, as a general rule of thumb the thinner pipe running from the compressor to the condenser (grill) next to a fan motor should always be placed uphill. Any oil that migrates during moving will then be sucked back into the compressor on start up.

    Once in position I would recommend leaving the fridge stand for approx 15 minutes to allow the internal system to settle.

  5. What's the difference between an integral and a remote cabinet?

    An integral cabinet is a complete all in one system example : a multi deck display cabinet has the display area complete with the refrigeration system underneath. You can basically move the cabinet into position and plug in.
    The benefits of this are the initial outlay is lower than a remote system.
    The cabinets can easily be moved or relocated without much effort.
    The disadvantage : as the compressor (motor) is situated with the cabinet the heat and noise produced will remain in the shop area.

    A remote cabinet means the refrigeration compressor (motor) is situated away from the main fridge ie a supermarket will have a refrigerated display cabinet within the store and the compressor located outside. The indoor cabinet and outdoor compressor are connected by two copper pipes and a electric supply
    The benefits of this is to reduce the temperature and noise level within the store and keep the compressor cooler therefore prolonging the live.
    The disadvantage is you will need specialist refrigeration engineers to separately install both indoor and outdoor units.

  6. Why choose a blast chiller / freezer?
    The traditional way of conserving cooked foods is to leave the food to cool until it has reached a suitable temperature to be stored in the refrigerator. At temperatures between +5c and +63c, bacteria quickly proliferate in foods. Lowering the temperature below +5c preserves the micro-organisms from reproducing. Therefore the sped with which food temperature can be reduced is critical to food safety. Blast chillers / freezers reduce food temperatures in the fastest possible way without destroying the food. This gives the highest of food safety.

  7. How do I stop my fridge from leaking water?
    Firstly check and make sure the cabinet is level

    If the water is leaking from within the fridge then the internal drain has probably blocked with food particles - a regular problem. The internal drain is located at the back of the fridge under the evaporator (back plate) clear the blockage (do not use a sharp object) once clear poor gentle cleaning fluid to help the drain.

    If the water is leaking from under the cabinet then the drain pipe at the rear of the cabinet has probably become dislodged. Turn the cabinet around, you will find a holding plate for evaporation water above the compressor, check the pipe drains into this evaporation tray, if the pipe has become dislodged reposition.

    On older cabinets the plastic evaporation tray may become brittle and crack therefore causing loss of water. These are fairly in expensive to buy.

  8. What should I do if I loose the power to my freezer?

    When you suffer loss of power, minimise opening the refrigerator and freezer. Refrigerators and freezers are insulated, aiding in keeping foods cold. However, if the refrigerator or freezer door is opened often, the cooling will be lost. Perishable refrigerated foods should be discarded after a 6-hour period. Using block ice may increase shelf-life of refrigerated foods.

    Food stored in fully loaded freezers may last for approximately two days, whereas food stored in partially loaded freezers may last for only one day. Freezer foods may be refrozen if ice crystals are present. Exceptions include ice cream, pizza, and casseroles. If the frozen food has completely thawed but is cold, it must be cooked within a 24-hour period; or foods may be refrozen within 24 hours after thawing. However, quality may be diminished. If in doubt about when the food actually thawed in the freezer, discard the thawed food. Discard all foods that may have been at room temperature more than 2 hours

  9. Could you please advise of delivery charges, we're interested in ordering a single door, drinks chiller unit.
    The delivery to UK mainland address are free of charge on the stardard delivery, usually between 3-5 working days. On most models are can offer a next day service but this is chargable depending upon the fridge. Call our sales team to discuss the delivery times 01743 289418 - thanks for the enquiry, hope this helps

  10. One of our supplier has quoted for Freezer( -20degC) with STATIC Cooling system, as he mentioned in his specs as -'NO FROST'. As a layman, how do i understand about teh static cooling? Will there be no frost in such system? or Do we need to manually defrost such a freezer? please reply with your valuable answers.
    if its a static cooling it will not be fan assisted therefore not automatic defrosting. Some freezers like Electrolux have a low frost system which is a small plate on the outside of the freezer which is designed to reduce ice build up within the cabinet. If its not automatic defrosting you will need to manually defrost the freezer hope this helps you thanks Keith
