Walk In Freezer Systems FAQ
What is a walk in freezer system?
A walk in freezer system is a complete low-temperature storage solution consisting of an insulated freezer room, freezer door, refrigeration equipment, evaporator, temperature controls and other required components.
What temperature does a walk in freezer normally operate at?
Many frozen-storage applications operate around -18°C to -25°C. The actual required temperature depends on the stored product, local requirements and the specific storage process.
What is the difference between a walk in freezer and a walk in cooler?
A walk in cooler is normally used for chilled storage above freezing, while a walk in freezer is designed for frozen storage at sub-zero temperatures. Freezer systems therefore require refrigeration, insulation, doors and frost management suitable for low-temperature operation.
Can CHENDUN customize a walk in freezer?
Yes. CHENDUN can discuss customized room dimensions, storage temperature, freezer panels, doors, refrigeration capacity, evaporator arrangement, shelving, controls and electrical requirements according to the project.
What information is needed for a walk in freezer quotation?
Useful information includes room dimensions, target temperature, product type, daily product quantity, incoming product temperature, door dimensions, door-opening frequency, installation location, ambient temperature and power supply.
Can a small walk in freezer be customized?
Yes. Small walk in freezer systems can be designed around available floor space, required storage volume, door location, shelving and refrigeration requirements. Compact systems are often used in restaurants, bakeries, grocery stores and catering facilities.
Can a walk in freezer be installed outdoors?
Yes. Outdoor walk in freezer systems can be designed for suitable weather and ambient conditions. Outdoor projects require additional consideration of rain, sunlight, temperature, humidity, electrical equipment and refrigeration components.
What refrigeration components are included?
Depending on the project, a walk in freezer refrigeration system can include a low-temperature condensing unit, freezer evaporator, expansion components, refrigeration piping, defrost system, temperature controls and electrical protection.
Can a walk in freezer be used for rapid freezing?
A standard walk in freezer is primarily designed for frozen storage. If products enter at a significantly higher temperature and need rapid core-temperature reduction, a blast freezer system may be more appropriate.
How is the refrigeration capacity of a walk in freezer determined?
Refrigeration capacity depends on room dimensions, insulation, target temperature, ambient conditions, product load, incoming product temperature, door traffic, lighting and other heat sources. A project-specific cooling-load calculation should be used for final selection.
What are walk in freezer panels used for?
Walk in freezer panels form the insulated walls and ceiling of the freezer room. They help reduce heat transfer between the low-temperature storage space and the surrounding environment.
What is a walk in freezer condensing unit?
A walk in freezer condensing unit is the refrigeration component that rejects heat from the refrigeration cycle. Its capacity and operating characteristics should be matched to the freezer's required cooling load and operating temperature.
