Granbering KW: Energy-Efficient High-Visibility Frozen Merchandising

When your business needs high-visibility frozen merchandising, but your priority is maintaining energy efficiency, where do you turn? The GranBering KW sits at the intersection of sustainable commercial refrigeration strategies that reduce environmental impact while maintaining performance. This low- and medium-temperature reach-in merchandiser was designed to support frozen food and ice cream applications while integrating with energy-efficient refrigeration systems across centralized and distributed platforms. Designed for Modern Refrigeration Architectures Retail supermarket refrigeration systems now require deliberate refrigerant selection and thoughtful system design. For higher refrigerant charge applications, the 150 GWP limit has accelerated the industry’s shift toward lower-GWP and natural refrigerant strategies. GranBering KW is a remote reach-in merchandiser designed for connection to centralized or distributed refrigeration systems. As a remote case platform, it can be used across a range of supermarket system architectures, including parallel rack configurations and distributed systems.  This flexibility allows retailers to standardize frozen case platforms while working with their refrigeration engineers to configure system architecture that aligns with regulatory requirements, regional energy codes, and sustainability objectives. Performance You See and Performance You Don’t Customers notice glass clarity and lighting. Operators notice airflow consistency and energy stability. There’s no reason you can’t have both. The GranBering KW delivers on all fronts, with LED lighting integrated into the mullion that evenly distributes light across the product face, and a ventilated cabinet architecture that supports consistent temperature distribution. Add in high-efficiency fan motors that reduce electrical demand, and you’ve checked every box. The quiet door-closing system prevents uncontrolled opening of adjoining doors and eliminates slamming. That small mechanical refinement reduces heat infiltration and improves system efficiency across the lineup. Remote electric defrost further supports stable performance in rack-based installations. Operational Efficiency Across the Lifecycle Installation and expansion are streamlined through the integrated camlock system, enabling quick case joining and seamless lineup extension. Top-mounted electrical components simplify service access and improve technician efficiency. Available in multiple height options and door configurations, the platform scales from smaller departments to full frozen aisles. Sustainable commercial refrigeration demands durability. Cabinet construction, airflow design, lighting efficiency, and system compatibility must work together. GranBering KW was engineered to meet those combined expectations. Supporting Applications with Valzer KW In smaller format stores or targeted promotional areas where a centralized rack is not practical, Valzer KW provides an alternative using natural R290 refrigerant. Valzer KW is a low-temperature, self-contained reach-in merchandiser developed specifically for frozen food and pre-packed ice cream applications.  Unlike remote cases that depend on centralized rack systems, Valzer incorporates its own condensing unit within the cabinet structure. This makes it well-suited for convenience stores, smaller retail footprints, remodels, and targeted department expansions where extending a remote system is impractical or cost-prohibitive. It complements centralized GranBering installations without disrupting overall sustainability objectives. GranBering KW remains the core solution for retailers modernizing frozen departments within advanced low-GWP refrigeration systems. It delivers the visibility customers expect, and the energy performance operators require, all within a platform aligned to today’s regulatory landscape.
