Existent Gum Evaporation Bath
Evaporates aircraft turbine fuel and motor and aviation gasoline samples
under controlled conditions in accordance with ASTM specifications. Consists
of a high temperature evaporation bath with 100mL test beakers and, for
aircraft turbine fuels, a steam generator and steam superheater.
Electrically heated baths for determining existent gum in aircraft turbine fuels
by steam-jet evaporation and in motor and aviation gasolines by air-jet
evaporation. Fully insulated, aluminum block design assures safe, efficient
high temperature operation. Equipped with air/steam pressure regulator with
gauge and a flowmeter for adjusting air flow per ASTM specifications.
Stainless steel jets deliver air or steam flow to the test wells through
removable brass conical adapters. Microprocessor PID control provides quick
temperature stabilization without overshoot, and the bath is protected by an
overtemperature control circuit that interrupts power should bath temperature
exceed a programmed cut-off point. Dual LED displays provide actual and
setpoint temperature values in °C/°F format. Communications software
(RS232, etc.), ramp-to-set and other enhanced features are available as extra
cost options. Contact your Koehler representative for information.
Model K33800 with Built-in Superheater–Six-unit bath with a
built-in thermostatically controlled superheater which delivers dried steam
to the bath inlet for steam-jet method testing of aircraft turbine fuels. Has
digital-indicating solid state bath temperature control with digital setpoint
Model K33700–Six-unit bath without built-in superheater. Controls are
housed in a separate cabinet connected to the bath by multi-conductor cable.
Model K33780–Three-unit bath without built-in superheater. All
controls are housed in the bath cabinet.
