Product Introduction

The cleanroom tunnel washer provides a linear, automated route for containers, trays, utensils, racks, or other compatible process items. Its modular chambers isolate each treatment stage, while dedicated pumps and spray manifolds maintain controlled mechanical action. The cleanable stainless enclosure, separated load and unload ends, recipe control, and accessible service zones suit validated hygiene workflows without assigning unverified performance to a specific project.

Key Features

Modular pre-wash, wash, rinse, disinfection, and drying sections

Adjustable stainless conveyor with load guides

Separate recirculation circuits to limit cross-stage carryover

High-coverage spray manifolds with removable nozzles

Fresh-water final rinse connection

Optional HEPA-filtered hot-air drying

Insulated stainless process enclosure

Recipe control with cycle status and alarm display

Customer Product Concerns

Large volumes of reusable components can create bottlenecks when processed in batch cabinets. Mixed soil loads, carryover between stages, and uncontrolled manual handling can also reduce repeatability at the clean-side boundary.

How is cross-stage carryover controlled?Independent chambers, dedicated circulation tanks, staged rinsing, and controlled conveyor travel separate the process functions.

Can the line fit a specific load and throughput?Conveyor width, chamber sequence, spray arrangement, belt speed, and loading interfaces can be configured around representative items and the required capacity.

How are difficult surfaces reached?Opposed spray manifolds and selectable nozzle patterns direct high-flow cleaning solution around exposed load surfaces; dedicated carriers can orient complex items.

Is maintenance accessible without compromising hygiene?Gasketed inspection doors, removable strainers and nozzles, sloped drainable chambers, and segregated service access simplify routine inspection and cleaning.

Typical Applications

Pharmaceutical component washingCleanroom container and utensil processingMedical-device reprocessing supportLaboratory cage and rack washingFood and biotechnology hygiene linesHigh-throughput controlled-area wash transfer

Technical Parameters

Loads travel on a controlled conveyor through dedicated stainless-steel chambers. Recirculating spray circuits, fresh final rinse, optional thermal disinfection, and HEPA-filtered drying can be arranged to match the load and cleanliness target. Interlocked access panels and inspection windows support safe maintenance.
