Custom blast freezer features include bimetallic couplers; low temperature (-40) DX ammonia evaporator system with smart hot-gas defrost; antimicrobial fin materials and coil construction; and USDA sanitary design for food processing applications. 

Industry experts note that starting with process-specific information is the most important first step when selecting a chiller.

With 0.125 to 2 ton capacity (2,100 to 24,000 BTU/hr), the portable J Series is suited for indoor plug-and-play applications. The brazed plate evaporator offers efficient cooling for many processes, including clean oil applications.

The intelliGen is a factory-mounted electronic control solution for evaporators that provides automatic superheat adjustment, temperature control and intelligent defrost control capability for walk-in coolers and freezers. 

The Danfoss CO₂ adaptive liquid management (CALM) solution, which fully utilizes all of an evaporator's surface area and improves the energy efficiency of transcritical CO₂ refrigeration systems by as much as a 10 percent, received top honors in the 2020 AHR Expo Innovation Awards program.

The business of industrial refrigeration covers a gamut of processes from high temperature process chilling to low temperature freezers. Industrial refrigeration is a large business sector: Its importance and impact within industries such as food processing and construction cannot be underestimated.

Hot gas defrost, a common and efficient method defrosting used within industrial refrigeration, can pose a safety risk if hot gas injection into the evaporators is not carefully controlled. 

Rooftop-mounted freezer systems contain air-cooling evaporators and fan systems enclosed in a highly insulated cabinet. 

One of the most frequent causes of operational problems with freezer and normal chilling temperature refrigeration systems is ice buildup on air coolers and evaporators, notes eurammon, a joint initiative of companies, institutions and individuals advocating an increased use of natural refrigerants.
