  • Cons: The R600a refrigerant is efficient but needs certified engineer handling.

Case Study: Real Business, Real Results

The Cornish Kitchen, a bustling seaside café in St Ives, needed to upgrade their old, inefficient under-counter fridge to cope with the summer tourist rush. Their previous unit struggled to maintain temperature, impacting workflow and  food safety.

"Our old fridge just couldn't keep up during peak season. The Polar G378 has been fantastic. It recovers temperature so quickly after we've been in and  out of it, and  the extra counter space on top has streamlined our entire sandwich prep line."

Sarah Jones – Head Chef

The upgrade resulted in a measurable outcome: they now handle 30% more lunch orders during peak hours without any food safety concerns.

Installation and  Maintenance Guide

Setting It Up

  • Ensure you leave at least 20cm of space around the unit, especially at the back, for proper ventilation.
  • Before plugging in, let the fridge stand upright for at least 4 hours to allow the refrigerant to settle.
  • Position on a flat, level surface, using the lockable front castors to secure it in place once positioned.
  • Give the interior a quick wipe down with a food-safe cleaner before you start loading it up.

Keeping It Going

  • Wipe down door seals weekly with a damp cloth to ensure they remain effective and  prevent energy loss.
  • Clean the condenser coils (usually at the back or side) every few months to maintain efficiency – a quick brush or vacuum will do.
  • Regularly check that the automatic defrost drain is clear to prevent any water build-up inside.
  • Avoid placing hot food directly into the fridge; allow it to cool to room temperature first to reduce strain on the compressor.

Buying Guide: Choosing the Right Counter Fridge

Not sure if this is the perfect fit? Here are a few things to consider when choosing your next under counter commercial refrigerator.

Measure Your Space

Check your dimensions twice! Remember to account for ventilation space around the back and  sides for optimal performance and  to prevent overheating.

Capacity vs. Usage

Think about what you'll be storing. A larger litre capacity is great, but ensure the internal layout and  adjustable shelving fit your specific containers and  produce.

Kitchen Temperature

Consider your kitchen's ambient heat. This heavy-duty Polar G378 counter fridge is rated for up to 43°C, making it ideal for hot, busy commercial environments.

Door Type

Solid doors like these offer better insulation and  are more energy-efficient than glass doors, making them the superior choice for back-of-house storage.

Ease of Cleaning

Stainless steel interiors and  exteriors are a must for any professional kitchen, allowing for quick, hygienic wipe-downs between services.

Frequently Asked Questions

Q: Can this fridge be built-in or does it need ventilation space?

A: It's a freestanding unit and  requires at least 20cm of ventilation space around the sides and  back for the cooling system to work efficiently and  prevent overheating.

Q: What does 'fan-assisted cooling' actually do?

A: It circulates cold air inside the fridge with a fan, ensuring a consistent temperature on all shelves and  helping it cool down much faster after the doors have been opened.

Q: Are the shelves adjustable?

A: Yes, this model comes with 3 sturdy, adjustable shelves, allowing you to customise the internal storage space to suit your specific needs and  container sizes.

Q: What does 'Climate Class 5' mean?

A: This is a rating that signifies the fridge is designed for heavy-duty commercial use and  can operate effectively in demanding ambient temperatures, up to 43°C.

Q: Is the defrosting process automatic?

A: Yes, it features an automatic defrost function which runs periodically to prevent ice build-up on the cooling element, maintaining peak performance and  saving you manual effort.

Q: Can the doors be reversed to open the other way?

A: The doors on this particular model are not designed to be reversible. They are hinged on the right for each section.

Q: What is the best way to clean the stainless steel exterior?

A: Simply use a soft, damp cloth with a mild, food-safe detergent. For tougher marks or to bring up a shine, a specialised stainless steel cleaner is recommended. Avoid abrasive pads.

Q: What type of plug does it have?

A: The Polar G378 comes fitted with a standard UK 3-pin, 13-amp plug, so you can plug it straight into a standard socket.

What Customers Are Saying

"A proper workhorse of a fridge. Solidly built, easy to clean and  keeps temperature spot on. The castors are a lifesaver for deep cleaning behind it."

"Fits perfectly under our main prep counter. The capacity is brilliant for its size and  the self-closing doors are a great feature for our busy kitchen staff."

Maria Rossi – Rossi's Deli, Glasgow

"Very reliable and  efficient so far. My only tiny niggle is the shelves can be a bit fiddly to adjust, but once they're in, it's brilliant."

How Fan-Assisted Cooling Protects Your Stock

Ever notice how a fan on a hot day cools you down faster than just sitting still? Fan-assisted cooling in this under counter commercial refrigerator works on the exact same principle. A small internal fan constantly circulates the cold air evenly throughout the cabinet, getting rid of 'warm spots' and  ensuring everything from the top shelf to the bottom drawer is kept at a consistent, safe temperature. This is especially vital when you're constantly opening the doors during a busy service, as it helps the fridge get back down to temperature in a flash, protecting your valuable ingredients from spoilage and  waste.

Who Should Buy This?

  • Restaurants & Bistros: Keep prepped ingredients perfectly chilled right where you need them, speeding up service times significantly.
  • Busy Cafés & Sandwich Bars: Ideal for storing fillings, salads, and  drinks under the counter to maximise precious workspace.
  • School & University Canteens: A robust and  reliable unit for high-volume food prep and  storage in demanding daily environments.
  • Catering Companies & Ghost Kitchens: A versatile and  mobile solution thanks to its castors, perfect for dynamic kitchen setups.
