NME454, 654 & FME504, 804

COMPONENT DESCRIPTION

Control Box: Contains the electrical controls that operate the machine.

High Pressure Cut Out Switch: An automatic reset switch sensing the high side refrigeration pressure. It is set to shut the machine off if the discharge pressure should ever exceed 450 PSIG.

Low Pressure Cut Out Switch

An automatic reset control that shuts off the ice machine when the low side pressure drops below a preset point, 15 PSIG.

Compressor: The refrigerant vapor pump.

Reservoir: Float operated, it maintains the water level in the evaporator at a constant level, it also contains the water level sensor.

Water Level Sensor: Senses if there is water in the reservoir to make ice out of. Will shut the machine off it there is no

water.

Ice Discharge Chute: Directs the ice produced by the evaporator into the storage bin.

Ice Level Sensor: An electronic “eye”, it senses the presence of ice in the bottom of the ice discharge chute. Operates to turn the ice machine on and off

ICE CHUTE

automatically as the level of ice in the bin changes. Gear Motor: An oil filled, speed reduction gearbox, driving the auger.

Condenser: Air or water cooled, where the heat removed in ice making is discharged.

Expansion valve: The refrigerant metering device.

FME504, FME804, NME654, NME454 specifications

Scotsman Ice Systems is known for its high-quality ice machines, and models such as the NME454, NME654, FME804, and FME504 are no exceptions. Designed with both performance and efficiency in mind, these machines cater to various business needs, from restaurants to convenience stores.

The NME454 and NME654 units are renowned for their compact design, making them ideal for establishments with limited space. Despite their smaller size, these machines do not compromise on ice production capacity. The NME454 can produce up to 430 pounds of ice per day, while the NME654 boasts an impressive output of up to 600 pounds. Both models utilize Scotsman's signature innovative technology to ensure consistent ice quality, primarily in the form of nugget ice, which is favored for its ability to cool beverages quickly.

In contrast, the FME804 and FME504 are larger-capacity machines that cater to high-volume requirements. The FME804 can produce around 800 pounds of ice daily, making it suitable for busy restaurants or bars. The FME504, while slightly smaller, still offers impressive production capabilities of up to 500 pounds per day. These machines incorporate advanced features such as the AquaArmor protective layer, which inhibits bacterial growth, ensuring that the ice produced is not only abundant but also hygienic.

All four models utilize an innovative air-cooled design that enhances energy efficiency and reduces operational costs. The easy-to-use control panel allows for straightforward operation, and maintenance is streamlined thanks to easily accessible components. Additionally, the quiet operation of the machines ensures that they can be used in front-of-house areas without distracting customers.

In terms of construction, Scotsman ice machines are built to last with corrosion-resistant materials, ensuring longevity in demanding environments. With simple installation processes and compatibility with various environments, including indoor and outdoor settings, these units provide adaptability for any business scenario.

Overall, Scotsman’s NME454, NME654, FME804, and FME504 ice machines combine robust performance with innovative technology, catering efficiently to diverse ice production needs while maintaining high standards of hygiene and reliability.
