Increase Refrigeration in Mechanical Spirals or Tunnels, and Blast Freezers
Cost-effective for Optimizing Capacity
The new liquid nitrogen powered NITROBOOST™ supplemental refrigeration systems give manufacturers the ability to maintain target operating temperatures in their existing mechanical tunnel and spiral freezers (NITROBOOST™ ST) or blast-style freezers (NITROBOOST™ BL). This avoids production downtime and the related temperature issues that occur from high heat loads and exceeding the freezer’s capacity. Made up of heat exchanger coils, using liquid nitrogen, the NITROBOOST systems are compact in size yet deliver substantial additional refrigeration capacity. Small enough to fit within or mounted on existing spiral or tunnel freezers. the systems use liquid nitrogen in closed-loop coils to efficiently and rapidly lower circulating air temperature.
A Boost for the Blast Freezer
Mechanical blast or shock freezers can struggle to reach their target operating temperature in an acceptable amount of time due to inadequate refrigeration capacity. It is often difficult for food processors to address temperature issues, since replacing the freezer or upgrading the mechanical refrigeration system can be very expensive and require weeks of downtime. Added to a blast or shock freezer, the NITROBOOST™ BL system from Linde helps under-performing or overloaded freezers reach the desired operating temperature faster. Processors can now keep products within specific temperature ranges and avoid the need to reduce freezer loading or operate additional hours or shifts.
Mechanical Spirals and Tunnels Also Benefit
The new liquid nitrogen powered NITROBOOST™ ST supplemental refrigeration system gives processors the ability to maintain target operating temperatures in their existing mechanical tunnel and spiral freezers. This can avoid production downtime and the related temperature issues that occur from high heat loads that exceed mechanical freezer capacity. The NITROBOOST ST system detects when the mechanical freezer is trying to reach its target operating temperature and triggers the liquid nitrogen flow to accelerate the cool down process to maintain a consistent operating temperature. The NITROBOOST ST system coils also can be set to defrost at different times relative to the mechanical system to optimize freezer production, defrosting and sanitation schedules.
