| Ice Machine - GB450 Series Ice Cuber on a B310 Bin |
![]() |
| Ice Machine - Stores 310 lbs. of ice, based on 35 lbs./cu.ft. at 90% of bin volume. |
Up To 460 lb. Daily Capacity
SIMPLICITY BY DESIGN
The KOLD-DRAFT 450 Series Classic Ice Cuber produces up to 460 lbs. of ice per day. It is
engineered with rugged unibody construction
and its time-proven design ensures reliable
operation, greater water efficiency and
maximum ice-making capacity. Serviceability
is from the front and the use of
environmentally-friendly R-404A refrigerant
gives greater efficiency.
The KOLD-DRAFT B310 bin holds 310 lbs. of ice.
The B310 has a stainless steel interior liner and
stainless steel exterior front, sides and back. It is
insulated with 2” of expanded foam insulation
and comes with sliding clear acrylic doors for easy
ice access and visibility.
THE HIGHEST QUALITY ICE
Ice that’s free from impurities. Ice that’s uniformly shaped ensuring maximum displacement and ease of handling.
Ice that sparkles, melts slowly and looks like ice should look. Three sizes of KOLD-DRAFT cubes to choose from that meet your exact needs. Full cubes, half cubes and cubelets – the highest quality ice.
STACKABILITY
GB Series Classic Ice Cubers are stackable with each other and can be stacked on existing KOLD-DRAFT GB Series Classic and Electronic Cubers. This unique “Add-A-Unit” feature will give you unsurpassed flexibility in ice-making capacity. So as your business grows, so can your ice capacity without using valuable floor space.
KOLD-DRAFT’s Commercial Ice Machine Warranty
KOLD-DRAFT’s warranty provides five years parts and labor on the entire machine and five years on the compressor and evaporator parts. More on the KOLD-DRAFT ice machine warranty.
