Refrigerator for Tray Trolleys

A refrigerator for tray trolleys is a key element in high-volume institutional catering, where hundreds or thousands of meal trays must be chilled and stored at the correct temperature before serving. Unlike a standard refrigerator, this unit is designed to accommodate an entire tray trolley—the internal dimensions precisely match the standard trolley size. The system significantly accelerates the meal preparation process and ensures HACCP compliance in large catering establishments.

Refrigerator for tray trolleys — operating principle

A refrigerator for tray trolleys functions differently from standard refrigeration units. Trolley insertion — a tray trolley with all filled meal trays is placed into the refrigerator via special rails or a lift. Uniform cooling — cold air is circulated throughout the entire trolley, chilling all trays simultaneously at a low temperature. Rapid chilling — high ventilation volume reduces chilling time from +65°C to +3°C compared to conventional refrigerators. Modular system — multiple refrigerators can be connected in a single system for larger volumes. Also explore refrigerators.

Technical parameters

A refrigerator for tray trolleys should be selected based on the trolley standard and the institution’s volume. Internal dimensions — match the standard GN tray trolley size (600×400 mm or another); it is important to verify the trolley size before purchase. Temperature range — +2°C to +8°C for storage; some models also feature blast chilling modes. Cooling capacity — an enhanced compressor for rapid chilling of large batches of hot meals. Capacity — 1 to 4 trolleys simultaneously, depending on the model. Material — AISI 304 stainless steel; hygienic and easy to clean. Also explore refrigerated tables.

Tray trolley standards

A refrigerator for tray trolleys is designed to match a specific trolley standard. GN 1/1 trolleys — standard 600×400 mm GN trays; the most common standard in institutional catering. Airline tray trolleys — custom-sized trolleys for airline catering; specific dimensions. Hospital tray trolleys — trolleys designed to meet medical facility standards, with the option for both hot and cold zones in a single trolley. Check compatibility — before purchasing, ensure the trolley’s external dimensions match the refrigerator’s internal dimensions. Also explore blast freezers.

HACCP and food safety

A refrigerator for tray trolleys helps ensure compliance with HACCP requirements in high-volume catering. Rapid chilling — HACCP requires chilling meals from +65°C to +8°C within 2 hours; a refrigerator for tray trolleys meets this requirement more effectively. Temperature monitoring — integrated temperature sensors and data logging for inspection purposes. Hygiene — stainless steel surfaces and an easy-to-clean interior. Segregation principle — hot meals are chilled before being stored alongside other cold products. BHS provides consultation on refrigeration equipment that meets HACCP standards.

HoReCa use cases

Hospital or care facility kitchens — a refrigerator for tray trolleys chills 200–500 portions of daily meals; rapid chilling ensures food safety for patient catering.
