Emerson spent more than three years researching and designing its 2018 Dealer Design Award gold-winning product in the Refrigeration and Ice Machines category.

As more states — and possibly the federal government — move to restrict the use of HFCs, it is likely that end users will soon start moving over to these alternative refrigerants, which means contractors should be prepared for that transition.

Refrigeration contractors who have not yet attended the annual National Restaurant Association (NRA) show really need to put it on their bucket lists. For four days each year, McCormick Place convention center is filled to the rafters with vendors exhibiting everything from gluten-free pasta to pizza ovens to high-tech ice machines.

In contrast to many other countries around the world, Americans consume a lot of ice. That’s probably why ice machines are found virtually everywhere here, from convenience stores and supermarkets to hotels and hospitals. It doesn’t really matter what shape it takes — cubes, flakes, nuggets, chips, etc. — but it does have to look and taste good.

In May, the International Electrotechnical Commission (IEC) released its draft proposal to raise the maximum charge size for flammable refrigerants in commercial self-contained cases from 150 grams to 500 grams.

It seems like charging a residential cooling system with refrigerant should be a fairly straightforward procedure.

Once considered a temporary solution, portable heating and cooling units continue to evolve as consumer demand calls for new units and new uses.

How can you tell when a system is low on refrigerant? Running a system check can determine whether that’s the case.

Some refrigeration systems are designed to be installed using a pre-charged line set.
