Dixell Digital Temperature Controllers – Medium & Low Temp Models

Who it’s for: Refrigeration techs and sparkies who want a fair dinkum 240VAC controller for display fridges, cold rooms, chillers and freezers. Dixell’s XR series gives accurate temp control, sensible defrost logic and reliable alarms — fewer call-backs and quicker sign-offs, no dramas.

• Power Supply: 240 VAC
• Probe Inputs: 2 × NTC/PTC (thermostat + condenser/evap)
• Digital Input: 1 × configurable (door switch, alarm, defrost start, pressure switch)
• Outputs: Compressor relay (model dependent — check variant specs)
• Applications: Display fridges, cool rooms, refrigerated cabinets, blast chillers

XR30CXB Medium Temp Controller – Blue

Built for larger cabinets and prep fridges where additional logic and alarm handling help. Popular for quick, tidy retrofits. View XR30CX-B.

XR40CXB Medium/Low Temp Controller – Blue

A robust, flexible option for multi-use control with defrost and door input logic — suitable across medium or low-temp depending on setup. View XR40CX-B.

XR60CXB Low Temp Controller

Optimised for freezer rooms and blast chillers with compressor protection and fast defrost recovery. View XR60CX-B.

Why this series matters

On a Sydney deli case last week, the old stat drifted and temps yo-yo’d. We dropped in an XR30CXB, set door alarms and sensible defrost intervals, and it held setpoint within a bee’s whisker — food safe and steady. That’s the XR series: simple interface, predictable control and bloody good stability.

Pro Tip

Always match probe type in parameters (NTC vs PTC) and calibrate offset after install. Door switch wired to the digital input lets you pause fan/compressor logic during loading — fewer nuisance alarms and faster pull-down.

Compatibility & System Info

• Supply: 240 VAC
• Probes: 2 × NTC/PTC (model dependent)
• Digital input: 1 × configurable (door/alarm/defrost start/pressure)
• Typical outputs: Compressor relay; defrost/fan outputs vary by model — see variant page
• Use cases: Display fridges, cold rooms, refrigerated cabinets, blast chillers

Local note: In humid Brisbane cool rooms, enable drip time after defrost and verify fan delay on evap probe to stop sling-off and frosting issues.

FAQs

Which model suits a small freezer room?

Use the XR60CX-B for low-temp duty and set probe-based defrost for faster recovery.

Can I reuse existing NTC probes?

Usually yes if they match the controller’s probe type/spec. If in doubt, fit a new Dixell NTC like the NG6P-1.5 or NG6P-10.

Is XR40CXB medium or low temp?

XR40CXB can be configured across applications, but our listing links to the low-temp variant. Check the series page for medium-temp options.
