Existent Gum Evaporation Bath

Gum formed during fuel storage can deposit on induction system surfaces, intake valves, stems and guides. To test for gum content, a 50mL sample is evaporated in an aluminum block bath for a specified period under controlled conditions of temperature and flow of air (aviation and motor gasolines) or steam (aircraft turbine fuel). Conforms to ASTM D381 and related specifications Choice of three-unit and six-unit models Safety top assembly allows for easy positioning and connection of all conical adapters to the bath Digital flowmeter for accurate and precise air flow measurement Available with built-in steam superheater Microprocessor programmable high accuracy temperature control Built-in pressure regulators and air flowmeters 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 digital 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 over-temperature control circuit that interrupts power should the bath temperature exceed a programmed cut-off point. Dual LED displays provide actual and setpoint temperature values in °C/°F format. Model K33900 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 and display. Conical Brass Adapters for air/steam jets Conforms to the specifications of: ASTM D381; IP 131; IP 540; ISO 6246; DIN 51784; FTM 791-3302; NF M 07-004 Testing Capacity: K33900: 6 sample beakers K33780 and K33781: 3 sample beakers Maximum Temperature: 475°F (246°C) Temperature Control Stability: ±1°F (±0.5°C) Bath Configuration: machined aluminum block with multiple cartridge heaters
