CO2 as a Refrigerant

Howe Rapid Freeze® CO2 Flake Ice Machines 

Howe has developed a line of Rapid Freeze® Ice Flakers that use CO2 as the refrigerant. The Rapid Freeze® CO2 Ice Flaker models are easy to install and set up—simply connect the ice flaker to water, power, and the refrigerant supply and return lines. Howe offers CO2 models which can produce up to 6000 pounds of flaked ice per day. The Howe Rapid Freeze® CO2 Ice Flakers eliminate the introduction of HFC refrigerants in your facility. The newest features on the Howe Rapid Freeze® CO2 Ice Flaker include electronically controlled EPR and Expansion Valves, pre-installed photo eye level control (ice storage bin applications), and optional ice management system. 

Refrigerant CO2 (R744) —Efficient and Good for the Environment 

Environmentally speaking, CO2 is a quality refrigerant with a Global Warming Potential of 1 and zero Ozone Depletion Potential. CO2 occurs naturally and is abundant in the atmosphere. CO2 refrigeration systems are designed to withstand pressures up to 1300 psi on the high side. In some instances, the systems are equipped with a small standstill condensing unit in order to keep pressures lower for safety. Volumetric efficiency and the range of the evaporation temperatures of CO2 are anywhere from four to twelve times better than ammonia and six times better than R-22. 

CO2 Refrigerant Ice Flakers are Cost Effective 

The price of CO2 refrigerant(R-744) tends to be relatively low, since CO2 is a by-product of many industrial processes. However, materials and equipment for CO2 refrigeration systems can be complex and more expensive than traditional systems. As the number of CO2 systems increases it is likely the cost will also begin to decrease. 

Howe CO2 Flake Ice Machines 

Howe Rapid Freeze® CO2 Ice Flakers can produce 1,000 to 6,000 pounds ice per day and are commonly used in both industrial and retail applications. Howe Rapid Freeze® CO2 Ice Flakers produce ice with an ice hardness rating of 100. This means that all the ice product produced 100% ice. Our Ice Flakers are known for their longevity and outlast the competition by 2-3 times in product life cycle. They are some of the most energy efficient machines available on the market. Available in a number of sizes and electrical requirements to fit your facility and process needs.
