What is Type II refrigeration and what does it mean?

NSF has two groups of operating conditions under which display cases can be approved for use.

  • Type I – Cases operating in environments that don’t exceed 75ºF and 55% relative humidity.  At a minimum, all display cases must pass this criteria.
  • Type II – Cases operating in higher ambient conditions up to 80ºF and 60% relative humidity.

Although the conditions for Type II appear only slightly higher than Type I, the 5 point increase in both temperature and humidity is a very big deal.

With onsite food preparation and energy management systems in place, many foodservice locations operate with conditions closer to the Type II range than Type I. Food display cases with self-contained refrigeration systems must be able to adapt to the environments they are operating in. Structural Concepts designed Breeze-E to operate in the “real” world and it’s capable of operating in NSF Type II conditions all the time.

The key difference between Structural Concepts and other manufacturers is that we design and assemble our own refrigeration packages.

Every condensing unit is sized exactly for its application and then assembled for each case. SCC’s custom-sized refrigeration packages outperform pre-sized off-the-shelf units commonly used by other manufacturers. These one-of-a-kind operating solutions simply could not be achieved without the ability to assemble refrigeration packages onsite.

Temperature consistency is the key to refrigeration success but that is increasingly tough to guarantee. Smart thermostats and energy management systems have been incorporated into buildings in order to reduce energy consumption and save money. These systems are challenging to food display equipment. An environment that is well controlled during the day can easily reach much higher temperatures during non-operational hours. As a result, refrigeration systems that are preset to operate in a specific set of temperature parameters are required to work harder as the operating conditions become more extreme.

Refrigeration systems are getting smarter.

Intelligent systems can sense the conditions of the environment and adjust the refrigeration cycle accordingly to ensure safe product temperatures are always consistent no matter how the environment is changing around it.

With more fresh food being offered in a variety of locations, it’s critical that food display equipment is reliable in order to safely maintain proper food temperatures. Equipment that includes the latest advancements in adaptive technology provides operators with the peace of mind that equipment will operate properly at all times. Structural’s Breeze-E offers a robust system designed to operate in these higher ambient environments.
