Unexcelled Energy Efficiency

Howe's Rapid Freeze Flaker utilizes an innovative extended surface evaporator design and unique material combination to offer significantly superior heat transfer characteristics over most ice machines in the industry. As a proven innovator for over 50 years, Howe brings a distinctive blend of technology and engineering expertise to enable Howe Flakers to operate at considerably lower cost than popular granular style flake ice machines.

Remarkable Longevity

The rugged "Open Style" Rapid Freeze evaporator design allows ice to be harvested by gravity, avoiding the punishing bearing loads that granular style flakers experience during harvest by an extrusion process. Howe's approximate 50% lighter bearing load enables Rapid Freeze Flake Ice Machines to frequently last three to four times longer than competitive machines. Standard units include stainless steel shaft, ice blade, ice deflector, squeegee wrapper & brackets, and all nuts, bolts & lockwashers.

Exceptional Quality Ice

Rapid Freeze units produce the "Authentic" 100% dry, sub-cooled flake ice that contains approximately four (4) times more surface area than many competitive flake ice machines. When compared to granular style flake ice machines whose production is only partially frozen (between 65% and 70% ice quality), Howe Flake Ice offers significantly greater cooling capacity, and lasts up to 20% longer.

Reliable Ice Production Capacity

Howe Rapid Freeze Flake Ice Machines are some of the only flakers which voluntarily base model numbers on daily capacities using ARI conditions of 70ºF water and 90ºF air temperatures (21ºC/ 32ºC), de-rated for 100% ice. Compared to comparable model granular style flake ice machines, it is not uncommon for Howe Flakers to produce approximately twice as much ice as competitive units at ARI conditions.

Warranty Protection

See complete warranty for details.
  • 25 year evaporator warranty
  • 10 year ice blade warranty
  • 2 year parts warranty
  • 5 year compressor warranty (optional)

Patented Bin Ice Level Control System

For maximum bin storage, infrared control turns machine off when ice level reaches chute.

The Low Ambient Kit

Ice flakers are designed for ambient temperatures between 90ºF & 60ºF. When installing in ambient temperatures below 60ºF, a Low Ambient Kit is recommended.

The Low Ambient Kit consists of 3 replaceable heating elements to prevent ice from forming on the bottom of the machine.

Available as factory option when ordering new equipment only.
