For almost 20 years, Staycold have been using their expertise to manufacture Sub-Zero beverage coolers.

Understanding Sub-Zero Beverage Coolers

A Sub-Zero beverage cooler is different to a regular beverage cooler as it can maintain the temperature of the product within it at below zero temperatures, whereas a regular beverage cooler averages between 3°C to 5°C depending on the specifications.

This Sub-Zero performance requirement has both taste and practical benefits for various users. From a taste, or more accurately, refreshment perspective, in the heat of Africa there is nothing better than taking a sip from an Ice-cold beverage. Some maintain that by crossing that 0°C line you benefit from enhanced taste and a more direct thirst-quenching experience.

Staycold Sub-Zero coolers are sometimes referred to in the trade as “Super Sub-Zero” coolers due to their ability to keep all the products within them below zero, at an average temperature of -3°C. Other suppliers offer “Sub-Zero” units that have an average of temperature of -1°C but because of this higher average temperature, not all the products are below 0°C.

This leads us to the second benefit of a Sub-Zero cooler. The performance required from the refrigeration system to achieve this temperatures, especially, as is the case of Staycold Sub Zero coolers, at ambient temperatures of up to 40°C.

This increased performance means that Sub-Zero coolers are often used in environments where fast “pull down” speeds are required – the speed that a cooler “chills” product down from ambient after it has been placed in the cooler. This makes Sub-Zero units an excellent choice for busy/high throughput outlets.

In refrigeration, mechanically and technically, a lot happens, and a lot can go wrong, as you cross the 0°C threshold. Water vapor freezes, glass doors can condensate considerably, door gaskets need to be fit for purpose, accurate temperature control is critical and the whole package needs to work reliably and effectively.

This is why Staycold’s superior build quality, engineering and design, coupled with EC fan motors, Digital energy management devices and Low-E glass doors are ideally suited for the requirement and offer piece of mind to their owners.

Background to Staycold’s current range of Sub-Zero Coolers

Staycold’s first Sub-Zero cooler was its HD690Z. A unit that was first developed almost 20 years ago in 2007. Marketed at the time as a Fast Lane cooler – designed for high traffic areas where rapid cooling was necessary. We were able to take many of the learnings from our display freezer range which was launched a few years earlier, and package it into this high-performance beverage cooler.

It was not until 2011, when the Sub-Zero cooler concept was adopted by one of the larger breweries in South Africa, and they approached Staycold to develop a double door unit that they could use in their busy main market accounts. Staycold duly obliged and our HD1140-Z was developed and released. A 930L double door unit capable of keeping just under 600 x 330ml bottles at an average temperature of -3°C.

The HD1140-Z along with the HD690Z, as part of our goal to lower the global warming potential (GWP) of our units, were subsequently made available with R290 hydrocarbon refrigerant. The HD690-ZHC and the HD1140-ZHC now form a significant part of our model output due to their now proven reliability and durability where it matters – out there, in the real world.

Our current range of Sub-Zero Coolers:

Our range has been further expanded to include the HD890-ZHC, which means that we now have a Sub-Zero cooler available for all requirements:

• HD690-ZHC – Single door unit, with a capacity of 315x 330ml bottles or 560x 300ml Cans
• HD890-ZHC – Small double door unit, with a capacity of 420x 330ml bottles or 672x 300ml Cans
• HD1140-ZHC – Standard double door unit, with a capacity of 560x 330ml bottles or 896x 300ml Cans.
