Features of Guardian® Self-Contained Freezer

The Guardian® Merchandiser puts your products front and center. Its self-contained design simplifies setup and merchandising, while presenting your items in a clean, eye-catching display—perfect for capturing shopper attention in dollar stores, small format shops, and remodels.

ChillBrite® LED Lighting
LED lights offer even, energy-efficient illumination, ensuring your products look their best without fading.
Doors
CoolView® Envision 30” standard 68” doors. Designed to resist condensation and sweating, even in humid store conditions. Available with 2 to 5 door count.
Reverse Airflow Design
Thanks to a reverse airflow design, frost naturally forms on the external coil rather than on your products or door surfaces—reducing frost buildup where it matters most and helping maintain clear visibility and product integrity.
Structure
Engineered with a durable structure capable of supporting PRUs plus an additional 250 lbs. All cases undergo rigorous ceiling load testing to ensure long-term strength and reliability.
Plug and Play
Roof-mounted packaged refrigeration unit (PRU) allows for the case to be ready to go quickly by simply plugging in the case. With the system being on top of the case, this allows for easy serviceability.
Installation
Designed for effortless installation, this case is the easiest many installers have ever worked with. It fits through a standard 80” doorway without tipping or disassembly and can be moved directly from truck to store with a forklift—streamlining setup from start to finish.
