Costan Supermarket Refrigeration Repair & Maintenance

Costan, part of the EPTA group, produces a wide array of commercial refrigeration solutions tailored for supermarkets, hypermarkets, and various retail formats. These include, but are not limited to, vertical and semi-vertical display cabinets (e.g., Opera, Tango, Glee), island freezers (e.g., Sound, Stage), serve-over counters (e.g., Velos, Aeria), and integrated refrigerated cold rooms. Each system is designed with specific operational parameters, refrigerant types, and control mechanisms, demanding a precise and informed approach to service and repair.

The complexity of Costan systems often stems from their advanced control panels, sophisticated defrost cycles, and integration into store-wide building management systems. Our engineers are trained to work with the diverse range of refrigerants typically found in these units, from traditional HFCs to newer, more environmentally friendly alternatives such as R134a, R404A, R407A, and R449A, ensuring compliance with evolving F-Gas regulations during any intervention.

Even the most reliable Costan equipment can encounter issues. Recognising these common faults and their underlying causes is crucial for effective diagnosis and repair:

**Temperature Fluctuations:** This is a frequent concern, often stemming from issues such as a failing compressor, blocked condensers or evaporators, refrigerant leaks, or faulty temperature sensors. In Costan multi-deck cabinets, uneven air distribution due to obstructions can also cause localised warming.

**Excessive Icing/Frost Build-Up:** Typically points to a problem with the defrost cycle (faulty heaters, defrost timer, or sensor), poor door seals, or an issue with the evaporator fan not circulating air correctly. This reduces cooling efficiency and can damage produce.

**Refrigerant Leaks:** Identified by reduced cooling capacity, higher energy consumption, or an audible hiss. Leaks can occur in pipework, joints, or components like evaporators and condensers. Our F-Gas certified engineers are equipped with specialist leak detection tools.

**Noisy Operation:** Unusual noises can indicate failing fan motors (evaporator or condenser), compressor issues, or loose components. Early detection can prevent more severe breakdowns.

**Drainage Problems:** Blocked condensate drains can lead to water pooling in the cabinet, risking electrical shorts and hygiene issues. This is often caused by mould, debris, or a misaligned drain pan.

**Control Panel Errors:** Modern Costan units feature advanced electronic controls. Error codes or unresponsive panels often require specialist diagnostic tools to identify underlying electrical or sensor faults.

When you call BritOne Air for Costan supermarket refrigeration repair, you engage a team committed to precision and efficiency. Our repair process is structured to minimise disruption and ensure a lasting solution:

**Initial Site Visit & Safety Assessment:** Upon arrival, our engineer will conduct a thorough safety check, isolate the unit if necessary, and review any site-specific safety protocols.

**Systematic Diagnostics:** Utilising advanced diagnostic equipment, our F-Gas certified engineers will methodically assess the Costan unit. This involves checking refrigerant pressures, electrical circuits, component functionality (compressor, fans, valves), temperature sensors, and control panel diagnostics. For example, specific error codes on a Costan 'Velos' serve-over counter might point directly to a pressure transducer fault, allowing for targeted investigation.

**Root Cause Identification:** Beyond fixing symptoms, we focus on identifying the root cause of the fault. If a compressor has failed, we investigate why (e.g., sustained high head pressure, electrical surge) to prevent recurrence.

**Transparent Repair Plan:** We will clearly explain the identified issue, the proposed repair, the necessary parts, and the estimated timeframe. We always aim for the most cost-effective and durable solution.

**Professional Repair & Testing:** Repairs are conducted using high-quality, manufacturer-compatible parts where appropriate. Following any repair, comprehensive testing is performed to ensure the Costan unit is fully operational, maintaining correct temperatures, and running efficiently. This includes leak testing if refrigerant has been handled and verifying defrost cycles.

In commercial refrigeration, compliance and safety are paramount, especially within a supermarket setting where food safety is critical. BritOne Air adheres to all relevant regulations:

**F-Gas Regulations:** All our engineers are F-Gas certified, ensuring that any work involving refrigerants in your Costan systems (such as leak testing, charging, or recovery) is performed legally and responsibly, minimising environmental impact.

**Food Safety:** Maintaining precise temperatures in Costan display cases and cold rooms is vital for preventing bacterial growth and preserving food quality. Our repairs focus on restoring optimal temperatures quickly, safeguarding your perishable stock and reputation.

**Health & Safety:** We operate in strict accordance with health and safety guidelines, conducting risk assessments before commencing work and ensuring safe practices are followed throughout the repair process, protecting both our engineers and your staff and customers.

Regular preventative maintenance is key to extending the lifespan of your Costan equipment and preventing costly breakdowns. While BritOne Air offers comprehensive planned preventative maintenance contracts, there are several actions you can take daily and weekly:

**Daily Checks:** Monitor display temperatures, ensure doors and lids are sealing correctly, and check for any unusual noises or odours.

**Weekly Cleaning:** Keep condenser coils clean from dust and debris to ensure efficient heat exchange. Regularly clean drainage trays and ensure they are free from blockages. For Costan multi-deck units, ensure shelves are not overloaded or blocking air circulation.

**Professional Servicing:** Schedule annual or bi-annual professional servicing with BritOne Air. Our engineers will perform in-depth inspections, clean critical components, check refrigerant levels, test electrical connections, and calibrate controls, identifying potential issues before they escalate.

Deciding whether to repair an existing Costan unit or invest in a new one is a common challenge. Our engineers can provide impartial advice based on several factors:

**Age and Condition:** Older Costan units may be less energy-efficient and more prone to breakdowns. If major components are failing on a regular basis, replacement might be more economical.

**Cost of Repair:** If the repair cost approaches a significant percentage of the cost of a new unit, or if multiple major components require replacement, investing in new equipment could offer better long-term value.

**Energy Efficiency:** Newer Costan models often incorporate advanced technologies for improved energy efficiency, leading to lower operating costs and a better return on investment over time. We can help you assess the potential energy savings of an upgrade.
