TYPHOON® RCP Reciprocating Nozzle Frame Washer The Proceco model TYPHOON® RCP is a batch-type power-spray washer designed to use water-based solutions to clean large, heavy workpieces. The double sliding doors permit top loading with a hoist or front loading with a forklift, and minimize floor space. Typical applications would be die washing or cleaning of diesel engine blocks prior to remanufacture. The basic model features a single circulating wash stage. Freshwater rinse and a full circulating second stage are available as options.
