Suitable Fluids
WARNING
: Use only fluids that comply with safety, health, and equipment compatibility requirements. Read
the safety data sheet for the fluid being used carefully before use.
The Chiller is designed to accommodate a variety of coolant fluids (water, glycol mixtures, etc). For most
applications above 15°C (59°F), distilled water is satisfactory. For operation below 15°C (59°F), the Chiller must
be protected with an antifreeze solution. Ethylene glycol (laboratory grade) and water in a 50/50 mixture is
satisfactory from +15° to -15°C (59° to 5°F). Select a fluid that is compatible with the Chiller’s wetted parts (brass,
bronze, stainless steel, EPDM rubber, nylon, PVC).
WARNING:
Do not use caustic, corrosive, or flammable fluids.
CAUTION:
Operation below 15°C (59°F) requires antifreeze in the circulation fluid. DO NOT use automotive
antifreeze as the additives may be harmful to the Chiller’s wetted parts.
DO NOT USE the following fluids:
• Automotive antifreeze with additives**
• Hard tap water**
• Deionized water with a specific resistance > 1 meg ohm (except units with the DI water compatible
plumbing
• Any flammable fluids
• Concentrations of acids or bases
• Solutions with halides: chlorides, fluorides, bromides, iodides or sulfur
• Bleach (Sodium Hypochlorite)
•
Solutions with chromates or chromium salts
•
Glycerin
•
Syltherm fluids
**
At temperatures above 40°C, additives or mineral deposits can adhere to the heater. If deposits are
allowed to build up, the heater may overheat and fail. Higher temperatures and higher concentrations of
additives can hasten deposit build up.
