THE ADVANTAGES OF 23NL
➢Clean solvent is available “on demand” every day. The parts washing operation becomes
much more pleasant and effective.
➢With the press of a button (shown on page 11.), the contaminated solvent is drained out and
5 gallons (18.9 Liters) of clean solvent are supplied in about 3 to 4 minutes, during which
time the parts washing operation is disabled.
➢The unit produces about 6 gallons (22.7 Liters) of clean solvent in about 4 hours without
interrupting parts washing operation.
➢Waste sludge is discharged into a waste container by operating the drain valve.
➢Dramatic savings in solvent purchase and disposal cost are achieved while improving quality
of cleaning operation.
➢Minimizes potential liability for inappropriate storage, handling and transportation of
hazardous waste.
➢Enhances compliance with environmental laws and regulations as well as improving
waste management status.
➢Considerable reduction of need for waste recovery services and prevention of
classification as a waste generator.
PURE SOLVENT AT ALL TIMES
Uni-ram model 23NL provides users with clean solvent every day, by removing all contaminants
from the waste solvent. The 23NL is designed to work using the vacuum distillation technology
thereby lowering the boiling point of contaminated solvent. Clean solvent is readily available at
all times by just pressing a button. This totally eliminates the need of waiting for weeks for the
Waste Hauler to deliver new solvent and disposal of old solvent. The great advantages provided
by 23NL are expected to help improving the environment of our world.

4) DEFINITIONS:
➢Flash Point or Flash Point Temperature.
Flash Point or Flash Point Temperature is the lowest temperature at which the vapor of a
solvent can be made to ignite momentarily in air by a source of ignition. Use only non-
flammable solvent with a flash point between 100°F to 143°F (37.8°C to 61°C) in this unit.
➢Auto-ignition Temperature (often referred to as “Ignition Temperature” or
“Ignition Point”): The temperature at which solvent ignites by itself. The lowest ignition
point of the solvent to be used in this unit is 392ºF (200ºC).
➢Boiling Point Temperature: (often referred to as “Boiling Point”or “B.P.”)
The temperature at which solvent starts to boil and turn into solvent vapor. The highest
boiling point of the solvent to be used in this unit is no higher than 374ºF (190ºC).This unit
performs distillation under strong vacuum which is known to lower the boiling point. On the
other hand, contaminants like oil and grease that go into the cleaning solvent during the
cleaning operation are known to raise the boiling point depending on the extent of
contamination.
➢Set-point Temperature.
This unit is pre-set at factory to Set Point temperature of 338ºF (170ºC), which is the
highest temperature available for distillation. This, however, does not mean the
temperature of Distillation Tank always goes up to the Set Point temperature. Actual
temperature of Distillation Tank displayed by LCD stays at lower level during distillation and
starts rising to the Set Point toward the end of distillation process. It will reach Set Point
when there is no solvent in Distillation Tank.
