1.0    General Overview

​

The frame of the NSP-515 is designed by North Scientific Products and fabricated from 304 SS. All vertical and horizontal structural members are 2 x 2 welded tubing with a ¼” SS plate floor. The perimeter sub frame is mounted on lockable casters for easy of mobility. Within the perimeter frame are integral support members for mechanical, electrical, and instrumentation mounting and to facilitate process piping and the distribution of power and instrumentation wiring.

 

All necessary process devices are mounted within the frame.

 

Control and operator interface to the distillation unit is accomplished via a touchscreen computer mounted in the face of the control enclosure. Manual control is available.

 

Electrical supply to the unit is a single point connection with a disconnect switch and emergency stop palm button mounted on the control enclosure.

 

Feed rate will be manually controlled by the User via a variable frequency drive wired to the positive displacement feed pump. Fully automatic control is available as an option. Automatic control, if desired, will be accomplished via a panel mounted touchscreen HMI. If selected,  writeable control points include jacket oil bath temperature, residue and distillate pump speed, feed pump speed, vacuum and backing pump start/stop, evaporator chilled circulator temperature, crude material feed rate, and wiper basket start/stop. Vacuum in each stage is displayed on the front of the control enclosure via three-line display and can be represented in Mbar, Torr, Pascal or Micron. Language can be displayed in English, German, Japanese, Chinese, French, Italian and Korean.

​

Wiper basket rotation is constant speed and accomplished via a ½ HP, 1800 RPM, TEFC motor and a 10.16 ratio gear motor.
