What the deep freezer programme covers
BEE's programme covers top-opening chest deep freezers, both hard-top (solid lid) and glass-top (see-through sliding or hinged lid) designs. Energy performance is tested to the Indian standard IS 7872, and BEE's own star-label portal lists deep freezers among the products in its mandatory labelling scheme. Because labelling rules are revised from time to time, check the BEE star-label website for the current status and the star table in force on the day you buy.
Upright freezers, ultra-low-temperature lab freezers and walk-in cold rooms are separate product types. If a unit is not a chest freezer, do not expect it to carry this label.
How the stars are worked out
The rating is based on Annual Energy Consumption (AEC), in kWh per year. The freezer is tested in a controlled room to measure how much energy it uses in 24 hours, and that figure is multiplied by 365. The resulting AEC is compared against star bands that rise with the freezer's storage volume, so a big freezer is not penalised simply for being big.
Hard-top and glass-top freezers have separate bands. A glass lid lets more heat in than an insulated solid lid, so a glass-top unit is allowed to use more energy for the same star level. That means a 4-star glass-top and a 4-star hard-top of the same size will not use the same electricity: compare the kWh figure, not just the stars.
What you will find on the label
- Star level, from one to five stars.
- Electricity consumption per year in kWh, measured under test conditions.
- Brand, model name or number and year of manufacture.
- Whether the freezer is hard-top or glass-top.
- Storage volume in litres, which is the usable volume after fittings, not the bigger gross figure some brochures quote.
- The label period, which tells you which star table the rating was given under.
Why the kWh number matters more than the stars
Stars rank a freezer against others of the same type and size. The kWh figure tells you what it will actually cost to run. When you are comparing two freezers of different sizes, or a hard-top with a glass-top, convert the kWh per year into rupees using your own tariff and compare those rupee figures directly.
Also remember that star tables are tightened over time. A unit that earned five stars under an older label period may not earn five stars under the current one. The label period on the sticker tells you which yardstick was used.
Label figures versus real-life use
Test conditions are fixed and repeatable, which is the point: they allow fair comparison. Your shop is not a test room. A freezer beside a hot tawa, in a non-air-conditioned kirana in May, or opened every few minutes for ice-cream cups will use noticeably more than its label figure. A freezer in a cool storeroom that is rarely opened may use less.
Use the label to compare models, then adjust your expectations for your own site. If your room is regularly hotter than about 32 °C, ask the supplier whether the model is designed to hold temperature at your ambient, and leave the clearance around the condenser that the manual specifies.
A buying checklist built around the label
- Choose the lid type first: hard-top for storage and stock, glass-top where customers need to see the product.
- Size for your real stock; an over-large freezer that is half empty wastes energy on cold air.
- Compare kWh per year across shortlisted models of similar size, then work out the yearly cost at your tariff.
- Check the label period is current and the label is the official BEE design, not a brochure graphic.
- Ask about the refrigerant, the thickness of the insulation and the operating voltage range, none of which the label shows.
- Ask who services the unit in your city; a poorly maintained 5-star freezer can use more than a well-kept 3-star one.
Frequently asked questions
- Does a 5-star deep freezer always use less electricity than a 3-star one?
- Only when you compare units of the same type and similar size. Stars are relative to volume and lid type, so a large 5-star freezer can still use more kWh than a small 3-star one. Compare the annual kWh figure on the label to see real consumption.
- Do glass-top freezers carry BEE labels too?
- Yes. The programme covers both hard-top and glass-top chest freezers, with separate star bands for each because a glass lid lets more heat in than an insulated solid lid.
- Where can I check whether a model's label is genuine?
- BEE runs a star-label website where registered models can be searched. If a seller cannot point you to the model's registration, treat the claimed rating with caution.
