High pressure pu machine

Using cyclopentane high pressure foaming machine, cyclopentane, an environmentally friendly foaming agent, is evenly and efficiently mixed with polyols and injected between the refrigerator shell and liner to form a dense rigid polyurethane foam layer. Compared to traditional foaming methods, high-pressure mixing not only improves the uniformity and stability of the foam, ensuring lower thermal conductivity and a longer service life for the refrigerator, but also reduces foaming agent waste and lowers production costs.

The Yongjia cyclopentane high-pressure foaming machine is specifically designed for producing insulation foam for refrigerators. Using environmentally friendly cyclopentane technology and equipped with a complete explosion-proof system, it ensures safe production. High-precision metering pumps, a stable mixing head, and intelligent PLC control guarantee uniform foam density and high cell closure rate in the final product.

High Energy Efficiency

Pioneer’s high-pressure mixing system ensures uniform dispersion of cyclopentane and polyols, resulting in a fine, dense foam that significantly improves the refrigerator’s thermal insulation performance.

Modular Design

The equipment’s modular structure allows for rapid adaptation to diverse production needs, from single-door to double-door to multi-door refrigerators.

Global Market Experience

Pioneer equipment has been widely used by refrigerator and freezer manufacturers overseas, demonstrating its proven technical solutions.

SPU High-Pressure Model Range for Reference

The parameters above are typical for refrigerator/freezer insulation. For the full SPU high-pressure model range (roughly 30-10,000 g/second) used across applications, see the specification table on the High-Pressure PU Foam Machine page and confirm the exact model with our engineers once cabinet size and blowing agent are set.

Configuration Decisions

What Changes the Quotation

Price and lead time depend on the blowing agent and explosion-proof requirement, output range, tank configuration, mold/fixture strategy and factory utilities. A useful quotation starts with the cabinet specification and blowing agent, not only the words “high-pressure machine.”
