- Frozen or chilled products display (a temperature range of around -18 to -25 °C for freezing type and around -2 to +8 °C for chilling type, in both cases an adjustable thermostat controls temperature as desired according to product type). As an option, some manufacturers produce displays with two separated displaying zones each with different temperature (called dual temperature, e.g. chilling & freezing).
- Display type:
- Open horizontal display; Fig.22.214.171.124, available as freezing or chiller type, freezing type is more common, suitable for frozen meats, sea foods, poultry, vegetables, processed dough (e.g. pizza), etc.
- Open vertical display; Fig.126.96.36.199, chiller type, commonly provided with air curtain(s) to reduce infiltration, suitable for displaying of dairy products, processed meats, processed sea foods, some types of vegetables & fruits, etc.
- Vertical display with glass doors; Fig.188.8.131.52, the most common use for this type is beverage bottles cooling (chiller type Bottle cooler), available also as freezing type, suitable for displaying of beverage and water bottles, fresh fruits & vegetable, dairy products, fresh meats (butcher shops), processed meats, processed sea foods, etc.

Remote type is recommended for super markets where; the exhausted heat from condensing unit is increasing super market temperature which accordingly increase the air conditioning load, also remote type eliminates high noise coming from compressor and condenser fan, built-in type has larger dimensions than remote type. Built-in type can be used for small capacities and/or when there is no available space outside the super market, in this case air conditioning designer attention should be invited – see storage equipments for more information about refrigeration equipments).
- Stationary or mobile (only displays with built-in condenser can be of mobile type).
- Capacity in liters.
- With or without rigid or flexible cover or blind , for open horizontal or vertical displays, cover or curtain is used before super market closing to save cooling capacity dissipated by open infiltration especially for vertical type).
