Summer is hard on commercial refrigeration. That is not a caveat or a worst-case scenario. It is the straightforward reality of running refrigeration equipment in Malta between June and September, when kitchen ambient temperatures climb, service volumes peak, and units that have been quietly accumulating wear through the quieter months start to show it.
Getting ahead of that means a service check before conditions worsen and, in some cases, a harder conversation about whether the equipment you have is worth carrying into another summer. We stock and fit a range of Bertos refrigeration units on spec: including a refrigerated worktop counter, an under-equipment refrigerated base, and a full-height upright cabinet.
What summer actually does to refrigeration
Commercial refrigeration is engineered to maintain precise internal temperatures regardless of conditions outside the cabinet. In practice, every degree of ambient heat makes that job harder. The compressor works longer cycles. The condenser has to shed more heat. Door seals that were borderline in January become a genuine liability in July, when every time a door opens, warm, humid air floods in and the unit has to work harder to recover.
Malta compounds this in ways that operators sometimes underestimate. Kitchen ambient temperatures in summer routinely exceed 35°C. In poorly ventilated back-of-house spaces they can go higher. A unit specified for a temperate European climate and installed in a Maltese kitchen without adequate clearance or ventilation will run hotter, consume more energy, and wear faster than its ratings suggest.
A refrigeration unit that is struggling in July was usually giving warning signs in April. The condenser was dirty. The door seal was soft. The temperature was drifting slightly off target. These are things a service check catches before they become a breakdown mid-service.
This is why the period between now and the start of high season is the right time to look at your refrigeration. Not because something has gone wrong, but because the cost of a planned service call is a fraction of the cost of a failed unit during a busy Saturday night in August.
What a pre-summer service check should cover
A refrigeration service check is not complicated, but it needs to be thorough. The areas that matter most going into summer are the condenser coil, the door seals, the temperature calibration, and the clearance around the unit.
Condenser coils accumulate dust and grease in commercial kitchen environments. A blocked condenser cannot shed heat efficiently, which forces the compressor to run harder and longer. Cleaning the condenser is the single highest-return maintenance task on any commercial refrigeration unit. It takes minutes and meaningfully extends service life.
Door seals degrade gradually. A seal that feels firm when pressed but shows cracking, compression marks, or any visible gap is already costing energy and temperature consistency. Replacement seals are a small cost. Running on a failed seal through a Maltese summer is not.
Temperature calibration confirms the unit is holding its target range accurately. It also provides a documented record for HACCP purposes, which matters for any operation storing produce or proteins.
Clearance is often overlooked after installation. Equipment gets moved, storage accumulates behind units, and the ventilation gaps that were correct on day one get compromised over time. A refrigeration unit needs adequate airflow around the condenser to function as designed. In summer, this matters more than any other time of year.
Spiteri Catering's technical team handles all of this. If your refrigeration was supplied and installed by us, we hold the service history. If it was not, we can still carry out a full check and advise on whether the unit is fit for the season ahead. Spare parts for units we supply are stocked or sourceable, which means a seal replacement or a condenser clean does not become a week-long wait.
The Bertos refrigeration range
Bertos is one of the core brands in our refrigeration offer. The range is built for professional kitchen conditions: robust construction, straightforward service access, and a configuration range that covers the main refrigeration positions in a commercial kitchen. All three units below are ordered on spec and available through Spiteri Catering. If the unit you need is not listed, contact us directly. The Bertos catalogue is broader than what currently appears on the site, and we can advise and supply across the full range.
Refrigerated Counter Smart Worktop, 4 doors
The Bertos Refrigerated Counter Smart Worktop, 4 Doors TN, is a refrigerated counter worktop with four-door access to a 1.31 m³ refrigerated interior. The Smart designation refers to the rounded-edge worktop profile, which gives a cleaner finish on the prep line and is easier to keep clean than a square-edged counter. At 230V/50Hz, it runs on a standard single-phase supply.
This is the unit for a busy prep section. Four doors mean four zones of access without a long reach across the counter. The worktop above is a functioning prep surface. Cold storage is immediately below the hands that need it. In a kitchen running at summer pace, the time saved by having ingredients at the point of use rather than in a cabinet across the room adds up across every service.
Refrigerated Base, 3 doors
The Bertos Refrigerated Base, 3 Doors is designed to sit beneath cooking equipment on the line, integrating refrigerated storage into the cooking station itself. With a 265-litre capacity across three GN1/1 positions and a temperature range of -2°C to 8°C, it holds proteins and prepped mise en place directly beneath the section where they will be used.
The practical argument for a refrigerated base is workflow: the chef does not leave the section to retrieve cold ingredients. During a busy service this is not a minor convenience. It is the difference between a line that runs cleanly and one that creates bottlenecks. Under summer conditions, there is a secondary benefit: cold ingredients that spend less time travelling between cold storage and the cooking position are less exposed to ambient heat.
Refrigerated Cabinet 1400 TN, glass door
The Bertos Refrigerated Cabinet 1400 TN with Glass Door is a full-height upright storage cabinet with a 1,180-litre net capacity across six GN1/1 grids, running at 0°C to 10°C. The glass door is the detail that earns its place in a busy operation: stock is visible without opening the door, which means fewer unnecessary door openings and a more stable internal temperature.
A cabinet this size is the backbone of cold storage for a medium to large kitchen. Six GN1/1 grids accommodate full gastronorm trays in rotation. The glass door makes stock checks and FIFO management faster and more reliable. In a kitchen where the brigade is moving quickly, being able to see what is in the cabinet without breaking stride is worth more than it sounds.
Ordering on spec and the wider range
All three units above are available to order on spec through Spiteri Catering. Lead times vary, so if you are planning a summer installation or a replacement ahead of the busy period, the right time to confirm an order is now rather than when a unit has already failed. The Bertos refrigeration catalogue extends well beyond what is currently listed on our products page, including saladettes, additional counter configurations, and blast chillers. If you have a specific requirement, contact us and we will advise on the right unit and lead time.
Frequently asked questions
How often should commercial refrigeration be serviced?
For most commercial kitchens in Malta, a minimum of one service check per year is advisable, timed before the summer season begins. High-volume operations, or kitchens where refrigeration runs in very warm ambient conditions, benefit from two checks annually. The condenser clean alone is worth doing every six months.
What are the signs that a refrigeration unit needs attention before summer?
Temperature drift, longer recovery times after door openings, audible compressor strain, and any visible deterioration in door seals are the four things to look for. If a unit is running consistently 1°C to 2°C above its target, that is a service call, not a dial adjustment.
Can I order Bertos refrigeration units that are not listed on the Spiteri Catering website?
Yes. The three units featured in this post are the refrigeration products currently shown on site, but the Bertos range is broader. Contact us with your requirements, and we will advise on specifications, pricing, and lead times. All orders are placed on spec with a deposit.
What does Spiteri Catering's warranty cover on refrigeration equipment?
All equipment supplied by Spiteri Catering carries a 12-month commercial warranty from the date of delivery, covering both parts and labour. For ongoing support beyond the warranty period, our technical team is available for service calls, scheduled maintenance, and spare parts supply.
If you are planning a refrigeration service check, a new installation, or a unit replacement ahead of the summer season, we would be glad to help you get it right before the heat arrives. Get in touch with the Spiteri Catering team and let us understand what you need. We handle everything from initial consultation and design through to supply, professional installation, and ongoing technical support.
