Hosokawa offers new composite downflow booth design

Provides excellent insulating properties, says company

Hosokawa Micron’s modular design downflow booth can be constructed using a new composite rigid polyurethane foam (PUR/PIR), which is said to offer significant advantages over the conventional double skin construction method.

This composite wall and roof panel uses metal-faced sandwich panels with rigid polyurethane foam core that bolt together to give a rigid structure. Using this new material provides users with excellent insulating properties, Hosokawa Micron says, aiding both soundproofing and thermal insulation. Temperature regulation is also easier because of the low heat losses, allowing temperature-sensitive operating environments to be kept economically at the correct temperature.

Each composite panel has an 80mm, CFV-free internal core of fire-resistant PUR/PIR with outer metal panels finished with a food safe laminate. PUR/PIR is strong and durable but the panels are lightweight and quick to install using a hidden self locking system that eliminates the need for traditional nuts and bolts. The roof can be designed to hold the weight of two men (200kg) in any position. Modular composite panel design can offer increased booth widths.

The panels offer significant advantages in terms of the positioning of internal equipment, windows, doors and ports owing to the tensile strength of the material and ease of cutting, moulding and frame sealing. This feature allows cables to be incorporated within the composite panels, reducing ledges, grooves and ridges that could harbour powder residue and dust.

Whether customers require a standalone downflow booth or complete clean air processing lines or separate dispensing facilities Hosokawa Micron engineers can oblige.
