Understanding the critical role of commercial refrigeration

Refrigeration plays a vital role in many businesses: keeping perishables in grocery stores and supermarkets, and keeping medication at the right temperature in healthcare facilities. An inadequate or faulty system can lead to spoiled products, compliance gaps, higher operating costs and, in the end, damage to your business’s reputation.

03 · The cost of a breakdown

What an unplanned shutdown really costs, worked out with your own numbers.

Move the sliders. Nothing is sent: the math happens on your screen.

With your numbers$6,400That’s what an unplanned shutdown can cost your business, before the repair bill.
Lost stock$4,000
Lost sales$2,400

Regular maintenance is how you avoid this: we catch wear before it turns into a breakdown. This calculation only uses the numbers you enter.

The equipment names in the cutaway below change based on what you keep cold.

04 · Your business, cut away

Seven spots that keep your products cold. Tap a number.

Each piece of equipment has its own temperature, signs of wear and maintenance. Yellow shows the heat going out, blue the cold coming in.

The weak spotKitchen heat and grease clog condensers fast. A dirty unit strains, uses more power and quits in the middle of the rush.
What we do for youMore frequent condenser cleaning in kitchens and a check of the prep table door gaskets.
05 · The refrigeration cycle

Cold isn’t made: heat is moved. Here’s how.

Four steps, one closed loop. Tap a step, then change the season to see what changes for your outdoor unit.

Normal summerThe heat taken from your products leaves through the condenser.
Step 4 of 4

Evaporator

Inside the unit, the refrigerant absorbs the heat from your products and turns back into a gas. Back to the compressor.

What fails here: Frost, stopped fan, failed defrost: the air stops circulating.
06 · Our services

Complete commercial refrigeration services, from installation to replacement.

Keeping optimal cold conditions has a direct effect on your operations. Pick a service: what we do, and what you get.

07 · Our personalized approach

Every business has its own refrigeration needs. We understand them before we propose anything.

We take the time to understand your needs, challenges and expectations before building a custom refrigeration solution. Six steps, from the first call to a unit that holds its temperature. They advance on their own; tap one to keep it on screen.

12 · The MAPAQ thermometer

Slide the thermometer and see whether your products stay in the safe zone.

The limits come from MAPAQ’s 5M approach for food establishments.

The MAPAQ rule
4 °Cchilled, or colder
−18 °Cfrozen, or colder
60 °Chot, or hotter

A well-maintained unit holds its temperature even at rush hour and during heat waves. Keep a thermometer in every unit and log your readings.
