Parts Washer Option: Hot-Air Blow-Off - Parts Drying

The Hot Air Blow Off (HABO) system speed dries parts by blasting them with high-velocity heated air in the parts washer at the end of a cleaning cycle. When dry parts are critical to the next operation the HABO is required to maximize the part flash drying function. While most surfaces flash dry, many parts have some pockets that retain water in pools. The HABO blows these pockets of retained water onto dry part surfaces. Heat evaporates the remaining water. The High speed steam exhaust pulls cool dry air into the cabinet to allow for quick evaporation of moisture from hot wet parts and prevents steam discharge from the cabinet. The dual speed exhaust blower allows for adjustment of the normal steam exhaust to minimize heat losses.

HABO systems are fully integrated with the StingRay parts washer and include a TEFC fan motor direct-coupled to a balanced pressure fan, a duct heater with over-temperature protection, High-velocity conversion nozzles set close to the edge of the turntable, and a two speed steam exhaust blower that switches to high speed during HABO operation. The steam exhaust blower speed is adjustable to set normal system speed so steam is just retained inside washer without excessive exhausting. This saves energy as the high heat content of the steam is usually the main energy loss in the parts washer.  

StingRay Hot-Air Blow-Off Nozzles & Plenum			StingRay Hot-Air Blow-Off System blasts high velocity heated air at parts on the Turntable for accelerated drying

The HABO system activates after the wash and rinse cycles are complete. The Turntable continues to rotate throughout the HABO cycle.  Air is pulled from outside the washer cabinet by the high pressure blower and forced through electric heating coils. The heated air accelerates to high velocity as it travels through the plenum and out the tapered HABO nozzles. Heating units are sized to provide heated air a minimum of 120° F (49° C) above ambient. An adjustable temperature controller and high-limit temperature safety shutdown controls are provided.
