A Smarter Standard for Sustainable Commercial Refrigeration in Frozen Aisles

Retailers today are balancing merchandising performance, energy efficiency, and regulatory compliance under tightening GWP limits. Sustainable commercial refrigeration is shaping system design decisions across stores and industries. The GranBering KW was engineered with that reality in mind. It’s a low and medium-temperature reach-in merchandiser that delivers high-visibility frozen food and ice cream merchandising while integrating seamlessly into modern low-GWP refrigeration architectures.   Merchandising That Performs The full glass doors, combined with LED lighting integrated directly into the mullion, create even illumination across every shelf. Products remain clearly visible from multiple angles, supporting impulse sales and brand presentation. The quiet, gentle door-closing system automatically returns doors gently to their closed position. The benefit of this is reduced slamming, but that’s not all. It protects adjacent doors from being forced open and helps maintain internal temperature stability. In high-traffic environments, those details translate into measurable energy savings. Internally, high-efficiency fans and a ventilated architecture support consistent airflow. Remote electric defrost contributes to stable operation while maintaining product integrity. This leads to lower waste and a better consumer experience.   Built for Low-GWP System Integration Supermarkets with higher refrigerant charges now operate under a 150 GWP limit. That shift has accelerated the adoption of CO2 and R290 refrigeration systems, as well as distributed refrigeration systems, across North America. GranBering KW uses R290 (propane) as a refrigerant, and allows retailers to align frozen merchandising with sustainable commercial refrigeration architectures without redesigning the entire case lineup. Of course, sustainable commercial refrigeration depends on more than refrigerant choice. Airflow efficiency, lighting performance, defrost control, and cabinet insulation all influence energy consumption. GranBering KW addresses these elements in a cohesive platform designed for long-term performance.   Scalable, Serviceable, Practical Retail footprints evolve, and frozen categories expand, making forward planning crucial in any retail environment. The GranBering KW features an integrated camlock system that simplifies case joining and lineup growth. Electrical components are top-mounted for easier service access, with no electrical connections in the raceway. That improves serviceability and reduces downtime. Available in multiple heights and two- through five-door configurations, the GranBering KW provides scalability within a consistent design language.   A Complementary Self-Contained Option While GranBering KW is ideal for remote and rack-based systems, some retailers require self-contained solutions for smaller footprints or targeted expansions. Many convenience and small-format stores need a self-contained solution that installs quickly, operates efficiently, and aligns with sustainability targets. Our Valzer KW product answers that need. This low-temperature, self-contained reach-in merchandiser is purpose-built for pre-packed ice cream and frozen foods. It is optimized for smaller footprints while delivering the performance expected from sustainable commercial refrigeration systems. Together, these platforms allow retailers to maintain a unified merchandising strategy across centralized and self-contained applications. GranBering KW is the foundation that anchors frozen departments with regulatory alignment, energy efficiency, and strong in-aisle impact.
