The Hoshizaki (formerly Gram) F420L C DR G U is designed for commercial kitchens requiring dependable performance and efficiency. Combining robust construction with innovative features, it ensures food safety, energy savings, and ease of use.
With dimensions of 595mm (W) x 645mm (D) x 1901mm (H), this freezer is compact yet spacious. It offers a gross volume of 343 litres and a net usable volume of 265 litres, complete with five adjustable white shelves compatible with GN trays up to 483.8mm x 433mm.
The advanced air distribution system provides uniform cooling, maintaining precise temperatures between -25°C and -5°C. This ensures food safety by eliminating hot or cold spots, making it ideal for preserving perishable ingredients.
Rated Energy Efficiency Class C, the freezer consumes just 1,086 kWh annually, reducing operational costs. The Energy Efficiency Index (EEI) of 39.06 complies with ISO 22041-2019 standards, offering both cost and environmental benefits.
With a sound level of 39.7 dB(A), the freezer operates quietly, minimising noise in busy kitchens. Short compressor cycles also limit heat emission, helping maintain a comfortable working environment.
The integrated full-height handle and reversible door provide easy access and flexibility in placement. Internal LED lighting improves visibility, while features such as automatic defrosting simplify maintenance and cleaning, saving time in daily operations.
Using HC refrigerant R600a with a low global warming potential of 3, the freezer is environmentally friendly and energy-efficient. Its air circulation system ensures even cooling, improving performance and reliability.
A secure lock on the door protects stock, while adjustable shelving offers flexibility for different storage needs. The durable construction and thoughtful design make this freezer a dependable addition to any commercial kitchen.
