Halocarbon or Ammonia Refrigeration: Which Is Better for Cold Storage?

Halocarbon or Ammonia Refrigeration: Which Is Better for Cold Storage?

Choosing between a halocarbon refrigeration system and an ammonia system is an important decision when designing a cold storage facility. Both can provide reliable cooling and freezing, but the right choice depends on the required capacity, operating temperatures, energy consumption, safety requirements, and long-term costs. There is no universal capacity threshold that makes one refrigerant the best option for every project. The refrigerant and system design should be evaluated together, based on the facility’s actual operating conditions.

How should we defrost food

 Defrosting is just as important a process as freezing if we want to obtain quality food. In this case, the rules are just the opposite of those for a freezing process. While freezing processes should ideally be carried out in the shortest possible time, when it comes to thawing, the ideal is just the opposite, that they should be as slow as possible (within reasonable limits). A very common practice to avoid whenever possible is to defrost food at room temperature, as...

Radairan 20,000 CFM Air Handling Unit

The Radairan 20,000 CFM air handling unit is a device responsible for filtering air, controlling air speed, regulating air humidity, and more. Additionally, it is also used for cooling the environment. Therefore, it can be said that the price of the air handling unit is very cost-effective given its numerous applications. Air handling units can be broadly classified into two categories: building air handling units and industrial air handling units. These devices do not differ structurally; they only vary...

Refrigeration solutions for the meat industry

RADIRAN has designed wall-mounted evaporators for deep-freezing tunnels with high-flow motor fans and high static pressure available together with high-efficiency coils, in order to reduce freezing time and promote the formation of smaller crystals. To service these high cooling capacity demands, RADIRAN offers solutions and refrigeration systems using natural refrigerants (such as ammonia (R-717), propane (R-290) or CO2 (R-744) ready for commissioning thanks to their Plug & Play configuration. Cutting or processing rooms are among the areas with the highest risk of contamination, being classified...

Refrigeration as a quality and safety contribution to the meat industry

Refrigeration as a quality and safety contribution to the meat industry

“In order to contribute to the availability of food for a constantly growing population, demanding with the quality of the products of the meat industry" Meat becomes an ideal culture medium for the growth of almost any micro-organism. This is due to its nutritional qualities, neutral post-mortem pH (pH = 6.5), high water activity (aw = 0.98), and extrinsic factors such as temperature and oxygen concentration. Meat and meat products are perishable by nature and easily susceptible to microbial contamination and chemical...
