2.1 General Precautions
Ensure that company safety policies are followed at all times.
t
Disconnect power and follow proper lock-out|tag-out procedures
t
when performing maintenance inside system components.
Do not stretch the Cryohoses in order to attach them to the chiller or the
t
application. Instead, move the chiller or application in order to arrange
the hoses in a relaxed position. Allow adequate slack to prevent kinks.
System components are heavy. Follow proper lifting and rigging
t
techniques.
2.2 Heat Transfer Fluid
The system uses Dow Syltherm HF silicone heat transfer fluid (HTF). Do not
use any other heat transfer fluid.
There are several hazards associated with use of HTF:
— Temperatures as low as –75°C and as high as 250°C can cause severe
injury to skin, eyes, and other soft tissue. Use appropriate personal
protective equipment when working with HTF or near exposed hot or
cold equipment surfaces.
— Syltherm HF has a closed-cup flash point of 63°C (145°F) per ASTM D92.
According to NFPA and OSHA, it is classified as a Class IIIA combustible
liquid. Follow proper handling and storage procedures.
— Syltherm HF has a low surface tension and it can be difficult to avoid
spills when filling or draining the system. Once spilled it is extremely
slippery. Use absorbent material such as polypropylene pads to keep
the bench and floor free of spilled HTF.
— Waste HTF and absorbent must be disposed of as hazardous waste.
Refer to the product information and MSDS for more information.
