Dixell Digital Temperature Controllers – Medium & Low Temp Models

Overview

Dixell's XR series digital temperature controllers are essential for refrigeration technicians and electricians seeking robust 240VAC solutions. Designed for a wide range of applications including display fridges, cold rooms, chillers, and freezers, these controllers deliver precise temperature regulation and intelligent defrost logic. Experience fewer service call-backs and smoother project sign-offs thanks to their consistent performance and reliable alarm functions.

These versatile units offer accurate temperature control and sensible defrost cycles for optimal system efficiency. The XR series ensures predictable operation across various cooling demands, from small merchandisers to large blast freezers. Available in specific models tailored for medium or low-temperature environments, each controller is engineered for straightforward installation and dependable long-term use.

This range of Dixell controllers provides peace of mind with its predictable performance and user-friendly interface. Whether you're upgrading an existing system or installing new refrigeration, the XR series offers a reliable foundation for maintaining optimal temperatures and food safety.

Why It Matters

On a Sydney deli case last week, an old thermostat caused inconsistent temperatures, leading to potential food spoilage. By installing an XR30CXB, we were able to implement door alarms and optimal defrost intervals, ensuring the setpoint was maintained with exceptional stability. This is the hallmark of the XR series: a simple interface combined with predictable control and outstanding operational stability, reducing costly temperature fluctuations and improving system reliability.

What's Included

• Dixell XR Series controller (model as ordered)
• Mounting hardware (per model)
• User/parameter guide

Features & Benefits

• Power Supply: 240 VAC, ensuring broad compatibility.

• Digital Input: 1 × configurable input (door switch, alarm, defrost start, pressure switch) for enhanced control.
• Outputs: Robust compressor relay, with additional defrost/fan outputs varying by model to suit specific needs.
• Accurate temperature control for both medium and low-temperature refrigeration applications.
• Sensible defrost logic for efficient ice management and reduced energy consumption.
• Reliable alarms, including high/low temp, door status, and sensor fault, for immediate issue detection.
• Simple, intuitive interface for quick setup and easy parameter adjustment.
• Robust design, built to withstand the demanding conditions of commercial refrigeration environments.

Applications

• XR20CXB: Ideal for upright merchandisers and beverage coolers.
• XR30CXB: Built for larger cabinets and prep fridges requiring advanced logic and alarm handling.
• XR40CXB: A flexible, multi-use control option for both medium or low-temp setups with defrost and door input logic.
• XR60CXB: Optimised for freezer rooms and blast chillers, featuring compressor protection and fast defrost recovery.
• General suitability for display fridges, cool rooms, and various refrigerated cabinets.

Tradie Pro Tip

Always match probe type in parameters (NTC vs PTC) and calibrate offset after installation for precise readings. Wiring a door switch to the digital input allows you to pause fan/compressor logic during loading, which prevents nuisance alarms and ensures faster pull-down times. For humid Brisbane cool rooms, it's wise to enable drip time after defrost and verify fan delay on the evaporator probe to prevent sling-off and frosting issues.
