  • Patent number: 8857448
    Abstract: A tunnel washer that includes fluid exhaust paths that are optimized to minimize fluid transfer between chambers of the washer and minimize heat loss from each chamber of the washer. The fluid exhaust paths also facilitate uniform vapor evacuation from each chamber of the washer. The tunnel washer also includes spaced-apart double wall curtains for isolating chambers of the tunnel washer to prevent fluid and heat transfer therebetween, and to the exterior of the tunnel washer. The double wall curtains include surfaces that inhibit the curtains from sticking together during operation of the tunnel washer. The tunnel washer also includes an air manifold that provides uniform drying efficiency for articles of varying dimensions.

  • Patent number: 5810943
    Abstract: A washer apparatus (10) includes a washing chamber (W) with a plurality of spray nozzles (N) and a pump (P1) for circulating the washing fluid (F) through the spray nozzles (N) for cleaning the contents of the washing chamber (W). A pH sensor (20) contacts the washing fluid (F) and a digital pH controller (30) connected to the pH sensor (20) generates digital pH values of the fluid (F). An acid neutralizing system (80) and an alkaline neutralizing system (90) are provided for selectively injecting acid neutralizer and alkaline neutralizer into the reservoir (S, T), respectively. An electronic controller (12) controls the operation of the washer (10) and the acid and alkaline neutralizer injection systems (80, 90) in response to the pH of the washing fluid (F) as determined by the digital pH controller (30).

  • Patent number: 5759289
    Abstract: A washing chamber (10) is surrounded by corner manifolds (14) and interconnecting conduits (16) extending along top, bottom, and side walls of the washing chamber. The conduits have nozzles (12) therein for spraying washing and rinsing liquids into the washing chamber. A central header assembly (40) includes a conduit (42) extending from one of the headers to a terminal end adjacent a central plane of the washing chamber. The central header assembly includes a header (46) with a manifold portion (48) and a plurality of extending arms (50) with nozzles on opposite sides. The header manifold portion is connected with the terminal end of the conduit (42). In one embodiment, a pivotal fluid connection and valve (44) enables the header to pivot between a position in the vertical plane and a stowed position parallel to the top of the washing chamber. In another embodiment, a quick-connect coupler system (100) interconnects the header with an outlet at the terminal end of the conduit (42).
