The Thermaster SD-306K is a 306-litre heavy-duty supermarket glass sliding-lid freezer built to merchandise frozen stock at eye level in busy retail and food-service floors. Twin curved sliding glass lids, -18 to -22°C running temperatures and natural R290 refrigerant make it a reliable open-plan freezer for supermarkets, convenience stores, bottle shops and takeaway venues.
Why operators choose the SD-306K
- 306 L usable capacity — holds a full frozen range without crowding a compact 1006 mm footprint
- -18 to -22°C temperature range — keeps ice cream, frozen meals and seafood firm through service
- R290 natural refrigerant — energy-efficient and low-GWP for lower long-term running costs
- Two curved sliding glass lids — let customers shop the freezer directly while limiting cold loss
- 4 baskets included — organise product lines and speed up restocking
- Climate Class 7 rating — holds temperature in warm, high-traffic retail environments
- Heavy-duty castors — let staff reposition the unit for cleaning or floor changes
