The M-144TG Safety Unit is designed to blend steam and cold water in any desired proportion; the unit features a safety steam shut-off which prohibits passing live steam. User adjustable with a factory-set maximum temperature, this unit is equipped with dial type gauge that indicates the exact wash temperature in both Celsius and Fahrenheit. For maximum efficiency, it is recommended that a Strahman hose assembly (with shut-off nozzle) be used in conjunction with this unit. Hard piping from the unit discharge, or use with an open-ended hose, is not recommended. Our Temperature Indicating (TG) models (M-144TG) are equipped with a dial-type gauge that accurately indicates the wash water’s temperature. They also feature a specially designed blending chamber to thoroughly blend steam and cold water.
