Epsilon Compact Chiller – ToronChill™ Epsilon Series
ToronChill™ Epsilon Series is a horizontal Compact Chiller built for small industrial and laboratory instruments that need stable recirculating cooling water. Its low-height design fits under a bench to save space while supporting consistent thermal control for sensitive equipment.
This Compact Chiller platform supports a wide operating window (up to 5–65°C) and is commonly paired with analytical systems where temperature drift can affect data quality and uptime.
Epsilon Compact Chiller – ToronChill™ Epsilon Series Applications
- Spectrometers and mass spectrometry instruments
- Provides steady coolant temperature to improve measurement stability and reduce thermal drift.
- Molecular pumps and vacuum support equipment
