Container Washers

Grintek's tunnel parts washers — also referred to as tunnel-type spray cleaning machines or tunnel washers — are large-scale industrial automation systems purpose-built for high-volume, continuous cleaning operations. Parts enter the enclosed tunnel on a stainless steel mesh belt or roller conveyor, pass sequentially through spray washing, rinsing, and hot-air drying zones, and exit fully cleaned and dried — all without interrupting production.
As a dedicated tunnel parts washer manufacturer and supplier, GTK has delivered proven tunnel cleaning solutions to leading customers across wind power, heavy industry, automotive, hardware, and mechanical processing sectors. Each system is custom-engineered to accommodate specific workpiece dimensions, materials, contamination types, and throughput requirements, ensuring reliable performance across diverse production environments.
Select GTK tunnel washer models also incorporate energy-saving and environmentally compliant features including oil-water separation, closed-loop circulating filtration, and steam heating — reducing operating costs while meeting industrial wastewater discharge standards.
GTK tunnel parts washers currently cover five main application types:
Stamping Parts Conveyor Cleaners: High-throughput spray cleaning systems designed to remove stamping oil, metal chips, and particulate contamination from pressed metal components at production line speed.
Plastic Pallet Tunnel Cleaners: Enclosed tunnel washing machines for continuous cleaning of plastic pallets and logistics trays, restoring hygiene standards for food, pharmaceutical, and manufacturing environments.
Fastener Tunnel Cleaners: Mesh-belt tunnel washers tailored to the dimensions and production cycles of bolts, screws, nuts, and other small fastener components.
AC Parts Automated Tunnel Cleaners: Automated tunnel cleaning systems engineered for air conditioner compressor housings and related components requiring consistent, repeatable wash quality.
Industrial Tote Tunnel Cleaners: Large-format tunnel washing equipment for turnover boxes, logistics containers, and industrial totes — cleaning interior and exterior surfaces in a single continuous pass.
