Electrically heated evaporation bath for accurate determination of existent gum in fuels using air-jet and steam-jet methods, compliant with ASTM standards.
The Existent Gum Evaporation Bath is a high-performance, electrically heated system designed for precise determination of existent gum content in petroleum fuels. It supports steam-jet evaporation testing for aircraft turbine fuels and air-jet evaporation for motor and aviation gasolines, ensuring compliance with ASTM testing standards.
Built with a fully insulated aluminum block design, the system delivers safe, energy-efficient, and uniform high-temperature operation. Stainless steel jets provide controlled air or steam flow to test wells through removable brass conical adapters, ensuring consistent and reliable results. The integrated air/steam pressure regulator with gauge, along with a digital flowmeter, allows accurate adjustment of flow conditions as per ASTM specifications.
Advanced microprocessor PID temperature control ensures rapid stabilization without overshoot, while dual LED displays provide clear indication of actual and setpoint temperatures in °C/°F. For enhanced safety, the bath includes an over-temperature protection circuit that automatically interrupts power if preset limits are exceeded.
Model K33900 (Six-Unit Bath with Superheater):
Features a built-in thermostatically controlled superheater that delivers dry steam for steam-jet testing of aircraft turbine fuels. Equipped with digital temperature control and display, it ensures precise and stable operation.
Model K33780 (Three-Unit Bath without Superheater):
A compact system with all controls integrated into the bath cabinet, suitable for steam-jet testing. It meets output requirements for both three-unit and six-unit evaporation baths. The electrically heated boiler ensures clean and efficient operation, eliminating the need for fuel combustion. It requires only a water supply and electrical connection for operation.
The system complies with relevant ASME and NEC standards and is UL listed and CSA approved. It features a rugged construction with a durable Incoloy heating element for long service life. Safety features include automatic water level control, low water cut-off, steam safety valve, high-limit pressure cut-out with manual reset, and a steam pressure gauge.
Ideal for petroleum laboratories, refineries, and quality control facilities, this evaporation bath ensures reliable, safe, and accurate determination of fuel stability and gum content.
