Manifold Distribution Block for Cryogenic Spray Systems

Product Specifications

Technical details and manufacturing context for Manifold Distribution Block

Definition

In a Cryogenic Spray System, the Manifold Distribution Block serves as the central hub that receives cryogenic fluid (typically liquid nitrogen or CO₂) from the main supply line and evenly distributes it to multiple spray nozzles or application points. It ensures consistent flow and pressure to all connected outlets, enabling uniform cooling or freezing across the target surface. The block is typically machined from Stainless Steel 316L or Aluminum Alloy 6061-T6, materials selected for their low-temperature properties and corrosion resistance. It features an inlet port and multiple outlet ports, with internal flow channels designed to minimize pressure drop and promote equal distribution. The manifold is available with 4 to 12 outlets, and inlet connections range from 1/2 to 2 inch NPT, while outlet connections range from 1/4 to 1 inch NPT. Operating pressure is specified as 1.0 to 1.6 MPa, with a note that Flow capacity per outlet is 10 to 50 L/min at 1.0 MPa differential. Operating temperature range is -40 to 85 °C. Surface finish on internal surfaces is 0.8 to 1.6 μm Ra, and critical dimensions are held to ±0.05 mm. Weight varies from 2 to 8 kg depending on size. These values are directory reference ranges and must be confirmed for the specific model and application with the legal manufacturer or supplier. The manifold is a component used in cryogenic spray systems for applications such as food freezing, surface treatment, or thermal cycling. Proper selection requires consideration of flow requirements, number of outlets, connection sizes, and material compatibility. Verification of parameters and standards is essential before procurement.

Working Principle

The manifold operates by receiving high-pressure cryogenic fluid through an inlet port, which then flows into a common internal chamber. From this chamber, the fluid is directed through multiple outlet ports to individual spray lines. Internal flow channels are designed to minimize pressure drop and maintain equal distribution to all outlets, often incorporating flow control features or pressure balancing mechanisms. The design ensures that each outlet receives a consistent flow rate and pressure, enabling uniform cooling or freezing across the target surface. The operating pressure range is 1.0 to 1.6 MPa, and, which may affect sealing and distribution. The flow capacity per outlet is 10 to 50 L/min at 1.0 MPa differential. The manifold's internal geometry and surface finish (0.8 to 1.6 μm Ra) are critical for minimizing turbulence and pressure loss. The number of outlets can be customized from 4 to 12, and connections are NPT threaded. The working principle relies on the pressure differential between the inlet and outlets to drive the fluid through the system.
