Product Description:
Manufactured by Danfoss, the 084B4183 is a dedicated single coil case controller designed for individual refrigeration units and standalone display applications. This control module is focused on regulating temperature in single zones within retail refrigeration settings such as display cases, beverage coolers and specialized food storage units. The controller manages one evaporator coil with precise control algorithms to maintain steady product temperatures. Its simple and reliable design is ideal for situations where temperature control is more important than handling multiple zones. This functionality is great for smaller retail setups, convenience stores, and dedicated product displays that need consistent single-coil operation.
The 084B4183 features AKV valve control along with Pe signal monitoring to ensure proper refrigerant flow and pressure management. It includes five built-in relays that manage switching for defrost cycles, fan operation, lighting, and auxiliary equipment within the display case. The unit uses S2 injection control technology to manage liquid refrigerant injection, improving cooling capacity during peak demand. It supports CO2 systems, allowing it to work with natural refrigerants that meet current sustainability standards. The front-mounted display gives direct access to operational parameters, alarm conditions, and system status without the need for external monitoring tools. This integrated display makes troubleshooting easier and simplifies maintenance for technicians.
The 084B4183 supports a wide range of electrical setups, with a supply voltage range from 115V to 230V for flexible power connection. It has 6 inputs for analog signals for connecting temperature sensors, pressure transducers, and other measurement devices for effective system monitoring. Three digital inputs accommodate switches, alarm contacts and external control signals, enhancing operational flexibility. It has 6 digital outputs that send control signals to various case components, including fans, heaters and indicator lights.
