Hoshizaki's KML-250, KML-351 and KML-451: More Bang (Less Bulk) for Your Buck
We don't live in a 'one size fits all' world, so why would you look for an ice machine that performs for you that way? Some businesses require thousands of pounds of ice per day, and have no problem finding space for an ice machine the size of a small car. Other businesses require ice in lesser quantities and in doing so may not have the space available for a tall machine. Hoshizaki's Low Profile KML Series are shorter than the average cube producing ice machines, so you won't have to sacrifice space for reliable ice production. There are also various external factors that may affect your ice machine's performance, but these factors affect Hoshizaki ice machines far less than others.
All three of these ice machines (KML-250, KML-351, and KML-451) are ENERGY STAR qualified to begin with, and all produce Hoshizaki's traditional crescent cube. This cube is ideal for bars and restaurants as it fits well in a variety of beverages, and its shape and size fill glasses easily, without clumping together. These ice machines measure only 22 inches tall. Under a stairway, or in an area with a low hanging ceiling, you will now be able to fit a Hoshizaki KML ice machine.
On our site, we have been stressing the importance of understanding your how your ice machine will produce in stressful conditions. Today we will examine these three machines and see just how they stack up against one another. This is how they break down.
The KML-250 can produce 307 pounds of ice per day when air-cooled, and 314 pounds of ice when water cooled in ideal conditions. Ideal conditions are defined as 70 degree air temperature and 50 degree water temperature. When put under stress (90 degrees air, 70 degrees water), the air-cooled machine (KML-250MAH) drops its production rate by 22.5 percent down to 238 pounds per day. The water cooled machine (KML-250MWH) falls by only 10.6 percent, and will produce 284 pounds per day. Though water-cooled machines tend to keep ice production rates more consistent, they also tend to consume far more water than air-cooled machines. This has actually led to water cooled ice machines being banned in some areas. This water cooled machine consumes 123 additional gallons of water for each 100 pounds of ice produced.
While air cooled ice machines generally perform more poorly in stressful conditions than water cooled machines, Hoshizaki's tend to remain the most consistent. This is due to their stainless steel evaporator plate. While other companies’ evaporators are made of weaker metals that may sacrifice up to 30 percent of production, only Hoshizaki's is made from durable stainless steel. Because of this, Hoshizaki ice machines lose the least percentage of production under stressful conditions.
The KML-351 produces 333 pounds when air cooled, and 345 when water cooled in ideal conditions. When temperatures increase, the air-cooled unit's production drops to 282 pounds, a 25.5 percent loss, but the water-cooled unit drops a miniscule 5.3 percent, to 327 pounds. In cases like this, it may be appropriate to assess the cost of wastewater in your area. If you can get by paying for 131 gallons of water per 100 pounds of ice produced, then you will be able to ensure the most consistent performance from your ice machine at all times.
For the greatest production of these small and mid-sized cuber heads, we turn to the KML-451. The KML-451MAH (air cooled model) can produce up to 401 pounds of ice while the KML-451MWH produces 429 pounds per day in ideal conditions. When conditions are less than ideal, production drops 23 percent in air-cooled machines to 349 pounds. The water cooled KML-451MWH realizes almost no decrease in production at all, dropping by 2.8 percent to 417 pounds. The water cooled unit will however consume 110 gallons of water per 100 pounds of ice created. If your machine works at maximum capacity all day, it will consume over 450 gallons of water, in addition to the water used to create ice.
As you can see, water cooled ice machines allow your ice machine's production rates to remain incredibly stable despite negative external factors. They also tend to use far more water than air cooled machines. Therefore, when making your decision, be sure you do the math, make the calculations, and plan for the worst. That way, you are never surprised with your ice machine's production. All of these ice machines from Hoshizaki's KML series are designed to save space, and are great for smaller establishments with height restrictions.
