Eliwell EWRC 500 NT 2HP BUZZER AIR Cold Room Controller

The Eliwell EWRC 500 NT 2HP cold room controller provides comprehensive temperature regulation and refrigeration control for commercial cold rooms. Its five digital outputs, multiple sensor inputs and integrated buzzer allow refrigeration engineers to manage essential operating functions through a single control panel.

Part of Eliwell’s Coldface range, the EWRC 500 NT 2HP BUZZER AIR combines compressor management, temperature monitoring and flexible refrigeration control with connectivity options for compatible Eliwell systems. The controller supports cold storage applications in convenience stores, supermarkets and commercial refrigeration installations.

Key Features and Benefits

• 2HP compressor control: The dedicated compressor relay supports compatible single-phase refrigeration equipment.
• Five digital outputs: Manage refrigeration functions through multiple relay outputs.
• Flexible temperature monitoring: Connect up to three compatible NTC or PTC temperature probes.
• Digital input flexibility: Use two voltage-free inputs for compatible control functions.
• Integrated buzzer: Provide audible controller alerts alongside the digital display.
• Clear temperature display: Read operating information on the dual 3-digit LED display.
• System connectivity: Connect compatible configuration and monitoring accessories through TTL communication, with optional RS485 support.

Reliable Refrigeration Temperature Management

The Eliwell EWRC 500 NT 2HP controller gives engineers practical control over commercial refrigeration installations. Its multiple outputs support compressor operation and other refrigeration functions, while its probe inputs provide the temperature information that the control system needs.

The controller accepts three NTC or PTC analogue inputs and offers two voltage-free digital inputs. This arrangement helps installers configure the controller for the requirements of compatible cold room equipment.

Eliwell AIR and Monitoring Connectivity

The EWRC 500 NT BUZZER AIR supports connectivity with compatible Eliwell systems, including Unicard, TelevisSystem and Modbus RTU solutions. Engineers can use suitable interfaces and accessories to extend configuration and monitoring capabilities.

For HACCP data logging and Eliwell AIR functions, select the appropriate manufacturer-specified module and accessories. Confirm all connectivity requirements before ordering, as the controller alone does not provide every optional monitoring function.

Applications for the EWRC 500 NT Controller

Commercial Cold Rooms and Refrigerated Storage
