Many of the comments regarding refrigerators also apply to freezers.. There are however
3 main types to be aware of :-
Chest freezers - these are popular as domestic freezers and are generally good value
for money. Disadvantages are the amount of floor space that they take up, frequent
manual defrosting and stock control - very few premises have a chest freezer that
does not have something lurking down in the bottom that should have been used months
ago! There are now a number of stainless steel chest freezers available and also
white/stainless combinations.
Upright (manual defrost) - these units have fixed shelves which carry the refrigerant
gas. The shelves cannot be adjusted and will gradually build up with ice. Frequent
manual defrosts are therefore necessary. Heavy usage and high ambient conditions
can cause problems. They are however much more efficient when it comes to floor space.
Upright (fan assisted) - these units have a conventional fan assisted refrigeration
system and therefore you should not find much ice. Shelves are adjustable and the
units defrost themselves automatically. As you might imagine, they are more expensive
than either of the above although they are normally suitable for heavy usage and
higher ambient conditions.
