Lab Skills - Sizing of Laboratory Chiller.pdf

I may not speak much, but I’ve got an important job in the synthesis lab. Every day, I keep things cool—literally. Whether it’s a rotary evaporator, reflux condenser, or a jacketed reactor, I hold the temperature steady so reactions stay under control. When things heat up, I’m the one absorbing the excess, protecting sensitive compounds from thermal damage. Solvents, long hours, demanding protocols—I handle it all without complaint. I adapt to new processes with my programmable settings, always ready for the next challenge. I’m more than just a machine—I’m the backbone of precision and safety in every reaction run.

1. THE SCIENCE OF
STAYING COOL
Laboratory Chillers
Basics of
Sizing it Right

2. A laboratory chiller is a refrigerated recirculating cooling system
provides a precise and stable temperature environment by
circulating a coolant fluid (such as water, glycol, or a water-glycol
mix) through external equipment that generates heat.
⚙️ Chiller Components:
Compressor – Pressurizes and circulates the refrigerant.
Heat exchanger (condenser + evaporator) – Transfers heat from the system
to the air or water.
Circulation pump – Pushes the coolant through external equipment.
Reservoir/tank – Stores the coolant.
Controller – Maintains target temperature via digital/PID control.
Benefits of using laboratory chillers:
Precise Temperature Control:
Chillers allow for precise and consistent temperature control, which is crucial
for many experiments and processes. 
Reliable Results:
By maintaining stable temperatures, chillers help ensure reliable and
repeatable results in experiments. 
Reduced Waste:
Recirculating chillers can significantly reduce water waste compared to
single-pass cooling systems. Equipment Protection:
Chillers prevent equipment from overheating, extending their lifespan and
reducing downtime

7. Ensure ventilation around the
chiller is adequate
Check Electrical Connections
Coolant Level & Quality
Check for leaks in the coolant
lines or around fittings.
Regular Inspection - Air Filters &
Condensers
Inspect Pump Operation &
confirm that the circulating pump
maintains steady flow
Periodically verify and recalibrate
the digital controller for accuracy
Drain & Clean the Tank
Periodically
Refer to the Product manual for
scheduled preventive
maintenance.
Stick to recommended service
intervals for compressors, filters,
and seals. Avail Maintenance
