Commercial Refrigeration Electrical Parts
Pirouz Ltd is a trusted UK trade supplier of high-grade electrical parts engineered specifically for commercial refrigeration, cold storage facilities, and HVAC installations. Maintaining precise temperature control and preventing costly equipment downtime depends directly on the integrity of your electrical control circuits. We supply a comprehensive range of electrical components designed to withstand demanding operational environments, including sub-zero temperatures, high humidity levels, and continuous duty cycles.
Whether you are assembling new walk-in cold rooms, upgrading existing control panels, or sourcing urgent replacement parts for reactive maintenance, we stock reliable components from leading manufacturers. All items are held at our central Essex warehouse, ready for fast nationwide dispatch to help contractors and engineers complete projects efficiently.
Commercial Refrigeration Electrical Parts Range
Our inventory covers every critical electrical link in a commercial cooling system, from primary mains control down to low-voltage monitoring circuits. Each component in our stock is selected for field durability and compliance with British safety standards.
Digital Controllers and Thermostats
Electronic micro-processor controllers form the brain of modern refrigeration setups. We stock single-stage and multi-stage digital temperature controllers compatible with standard industrial panel cut-outs. These units feature bright digital displays, user-friendly programming interfaces, and customisable outputs for compressor regulation, evaporator fan management, and automated defrost cycles. Models with integrated RS485 communication ports allow for seamless connection to master building management systems (BMS).
Contactors, Relays, and Motor Starters
Electrical switching under heavy inductive loads requires rugged components. We supply 3-pole and 4-pole contactors fitted with AC or DC coils tailored for switching commercial compressors, condenser fan motors, and electric defrost banks. Thermal overload relays and phase failure monitoring modules provide essential protection against voltage spikes, single-phasing, and motor overheating, preventing expensive compressor failures.
Temperature Sensors and Probes
Accurate temperature sensing is essential for precise thermal control and energy efficiency. We stock high-precision NTC (Negative Temperature Coefficient), PTC, and PT1000 temperature probes sealed inside stainless steel or thermoplastic housings. Rated to IP67 ingress protection, these sensors deliver consistent readings when placed inside evaporator coil blocks, discharge air streams, liquid lines, or ambient cold room space.
Defrost Heating Elements and Drain Heaters
Frost accumulation on evaporator coils degrades heat transfer and disrupts airflow. Our range of defrost electrical parts includes flexible silicone heater cables, rigid stainless steel sheath heating elements, and insulated drain line heaters. Designed to operate under harsh thermal cycling, these heaters prevent ice buildup in condensate drain trays and drain lines, ensuring uninterrupted liquid drainage during defrost sequences.
Microswitches, Safety Interlocks, and Door Switches
Safety and energy conservation require automatic responses to physical door openings. We supply heavy-duty cold room door switches and roller-plunger microswitches rated for low-temperature environments. These interlocks immediately isolate evaporator fans when a cold room door opens to prevent warm air ingress, while simultaneously activating internal LED lighting and triggering open-door alarm timers.
Technical Specifications and Operating Standards
Selecting the correct electrical parts requires careful attention to operating parameters, load ratings, and environmental protections. Our commercial components meet standard trade specifications to suit standard UK installations:
- Voltage Ratings: Options available for standard 230V AC single-phase (50Hz), 400V AC three-phase industrial power supplies, and 12V/24V AC/DC extra-low voltage control loops.
- Ingress Protection: Enclosures, junction boxes, and terminal switches feature ratings up to IP65, IP67, or IP68 for washdown resistance and protection against moisture ingress in high-humidity chillers.
- Temperature Ranges: Sub-zero probes, door interlocks, and heater cables are certified for continuous operation in temperatures ranging from -40°C to +80°C.
- Regulatory Compliance: Standard electrical parts comply with relevant UKCA, CE, and RoHS standards, giving installation engineers full confidence in safety and regulatory compliance.
System Integration and Field Applications
In commercial cooling applications, electrical parts must operate seamlessly alongside mechanical equipment and structural insulation. When constructing walk-in chillers or freezers using high performance PIR insulated panels, properly routed electrical conduits and IP-rated surface junction boxes maintain panel insulation integrity while keeping control wiring safe and organized.
Electrical control panels also coordinate auxiliary equipment. Automated defrost cycles rely on clean electrical signalling sent directly to heavy-duty condensate pumps to clear melted ice runoff safely away from the cold storage footprint. Furthermore, keeping electrical components and temperature probes functioning at peak accuracy requires clean heat exchangers; pairing routine electrical inspection with an effective coil cleaner maintenance routine keeps airflow clear, reduces compressor run time, and prevents false temperature alarm trips.

Frequently Asked Questions
Which temperature sensor probe type do I need for my digital controller?
The correct probe type depends on your specific controller model. Most modern commercial refrigeration controllers use NTC 10K probes, whereas older or high-precision industrial systems may require PT1000 or PTC sensors. Always check the sensor input specification listed on the side of your controller or consult our technical team.
Are your electrical parts suitable for sub-zero walk-in freezers?
Yes, our specialized cold room electrical parts, including door microswitches, defrost heaters, and sealed probe sensors, are rated for continuous operation in low-temperature environments down to -40°C.
Do you supply replacement contactors for three-phase refrigeration compressors?
We stock a range of 3-pole and 4-pole contactors rated for inductive motor switching. These are available with standard 230V AC coils or 24V AC/DC low-voltage control coils to suit your panel wiring layout.
