AE865C  Specifications


Mini Degasifier

Physical specifications

23" (585 mm) Wide x 23" (585 mm) Deep x 46" (1,170 mm) // 275 lbs. (125 kgs.)

Input power

120Vac/60Hz - 220Vac/50Hz - other available configuration (choose it in the order)


One Strainer, complete with a 60 mesh basket.


One 3 KW Electric Inlet Oil Heater. The heater shall have a watt density not greater than 11 W/Sq. In. (1.7 W/cm2). The heater shall be capable of increasing the oil temperature 45ºF (27ºC) in a single pass. Fuses shall be used for over current protection of each bank of heater elements.

Temperature Controller

One Temperature Controller, which shall be used to control the electric heating elements to maintain the desired oil temperature. The controller shall be integrally mounted on the heating unit. The temperature controller, on deviation from the set point, activates the heater contactor which energizes the heating element, raising the oil temperature to the set point. The controller set point is adjustable by a dial, thereby changing the set point. The heater controller is designed to drop out the heating load on loss of power or vacuum. On resumption of power or flow, the controller resumes function and begins to energize the heating element as required.

Degasification Chamber

One Degasification Chamber. The chamber shall have a viewing port and a bolted service door.

Float Actuated Level Control Valve

One Float Actuated Level Control Valve. The valve is actuated by a float mechanism in the dehydration chamber to maintain the desired oil level. The level control valve is fully modulating and will maintain an inlet flow equal to the capacity of the discharge pump.

Vacuum Pump

One Rotary Vane Vacuum Pump, 6 CFM (10 m3/hr) capacity, blank off rating 0.02 mm Hg. Vacuum required for processing is created by the vacuum pump

Vacuum Gauge

One 0-40 mm Hg Vacuum Gauge to indicate the vacuum in the processing chamber

Vacuum Trap

One Vacuum Trap to protect the vacuum pump from water carry-over

Temperature Gauge

One Temperature Gauge, which is used to indicate the outlet temperature of the oil being processed.

Pressure Gauge

One Pressure Gauge, which is used to indicate the outlet oil pressure and filter condition.

Degasification Header

One Degasification Header, which shall contain chemically inert accelerator elements

High Level Detector

One (1) High Level Detector. This level switch shall stop the vacuum pump to prevent flooding and is a back-up for the flow control valve Float Actuated Level Control Valve

Low Level Switch

One (1) Low Level Switch shall be interlocked with the discharge pump to prevent it from operating unless sufficient oil head is present

Discharge Pump

One (1) Positive Displacement Discharge Pump, with mechanical seals and integral relief valve. The pump shall have a rating of 60 GPH (225 litres per hour) and shall be direct driven by a ¼ HP, 1200 RPM, TEFC electric motor.

Oil Filter

Oil Filter will be installed after the outlet pump. The Afterfilter is furnished with a micron selectivity of 0.5 microns and a filtration efficiency of 98%.
Standard filter units are of steel construction and complete with pressure gauge to monitor differential pressure.

All necessary pressure gauges and valves as shown on the Flow Diagram shall be provided to complete the system. Suitable flexible connections shall also be provided in the piping to minimize vibration. A NEMA 12 Control Cabinet shall be provided, which shall contain all necessary control items required for the system. All motors shall be provided with magnetic starters for full voltage, across-the-line starting. Each motor shall have sufficient overload protection. Fuses shall be provided with each motor starter. Also fuses shall be provided with each contactor for heater banks for over current protection. Two (2) 10 foot hoses 1/2" ID, material: EPR c/w Kamlok quick connects on each end. One 10 foot power cord. All components shall be suitable for 220 Volt, 1 Phase, 60 Hertz power supply. One (1) dry-type 100 VA transformer shall be supplied for control circuits. All piping shall be carbon steel, sized for the designed flow, braced and supported to prevent vibration. Piping will be welded construction when possible, to minimize leaks. Special vacuum tight welded 'O' ring unions and pipe flanges shall be provided to allow removal of components for maintenance, when necessary.

AE865C  Optional Upgrades

Viton Gaskets

Viton gaskets and seals can be incorporated in the Vacuum Oil Degasifier replacing Buna-N material
