Fluid
Selecting a fluid or fluid mixture for use in your FTS Systems BioCool™ 80 is the
single most important decision to be made. Always select a fluid that is appropriate for
the temperature and/or temperature range at which you will operate your system.
Improperly selected fluid can result in damage to both your process and your
equipment.
Refer to the following table for a list of fluids that may be used with the FTS Systems
BioCool™ 80.
CAUTION: BEFORE USING ANY FLUID PRODUCT, READ THE CURRENT
PRODUCT MATERIAL SAFETY DATA SHEET AND ANY PRECAUTIONARY
STATEMENTS ON THE PRODUCT PACKAGE. FOLLOW ALL APPLICABLE
PRECAUTIONS AND DIRECTIONS.

Fluid Filling
While operating at or above ambient temperature (approximately 22 °C (72 °F)), fill
the reservoir with your selected fluid until the fluid is about 1 inch below the gasket.
If you add fluid while the system is at a sub-ambient temperature and you fail to drain
fluid before returning the system to room temperature, the fluid may expand and
overflow the fluid reservoir.
Notes:
Fluids will typically contract when cooled and expand when heated.
The gasket at the top of the fluid reservoir does not provide a liquid tight seal.
If the fluid reservoir chamber is overfilled, the liquid will flow over the rim of the fluid
reservoir into the polyurethane insulation. Organic solvents will attack, dissolve and/or
render ineffective the chamber insulation. When the insulation is saturated with
solvent, the BioCool™ 80 may be unable to reach its maximum low temperature.
IF THE RESERVOIR IS OVERFILLED, THE FLUID MAY OVERFLOW THE
RESERVOIR RIM AND SEEP INTO THE POLYURETHANE INSULATION. ORGANIC
SOLVENTS WILL ATTACK AND DAMAGE THIS INSULATION MATERIAL,
RENDERING THE INSULATION INEFFECTIVE. WITHOUT ADEQUATE
INSULATION, THE BIOCOOL™ 80 WILL NOT REACH MAXIMUM LOW
TEMPERATURES.
