Hengel RS70E-US Chock Freezer-Storage Cabinet

• Rapid freezing of prepared foods to preserve quality and extend shelf life.
• Storage of frozen goods at consistent temperatures prior to distribution.
• Use in large-scale catering, bakeries, and food production facilities.
• Processing of delicate food items requiring quick temperature reduction to minimise crystal formation.

Typical operating temperature range

For this class of equipment, temperatures commonly range from -35°C for freezing down to -16°C for storage.

Refrigerant type

Units of this type commonly utilise modern, lower GWP refrigerants such as R448A or R449A.

Insulation

High-density polyurethane foam, typically 100mm thick, is standard for efficient thermal retention.

Tray compatibility

This model is designed for 460x660mm trays, a common size in professional kitchens and bakeries.

Construction material

Stainless steel exterior with a white interior is typical for hygiene and durability in food environments.

Defrost method

Programmable electric heater defrosting is commonly employed for efficient ice removal.

Power supply

Units of this capacity typically require a 3-phase electrical supply; buyers should confirm specific voltage and amperage with the seller.

• What is the primary benefit of a shock freezer over a standard freezer?

  Shock freezers rapidly reduce food temperatures, minimising ice crystal formation. This preserves the texture, flavour, and nutritional value of food more effectively than conventional freezing methods.

• Can this unit be used for both freezing and storage?

• What kind of maintenance does a unit like this typically require?

• Is assembly required upon delivery?

• What are the common safety features on such equipment?

Blast freezers hold strong reputations for reliable performance in food processing operations. Buyers typically prioritise units with sturdy construction and consistent temperature control, as these directly affect product quality and shelf life. When purchasing used equipment, inspecting refrigeration systems, door seals and internal surfaces for wear is essential. Industry sentiment favours models from established manufacturers known for durability. Key strengths include rapid freezing capability, energy efficiency compared to older freezing methods, and adaptability to various food types. Proper maintenance history significantly influences buyer confidence in used units.
