The Julabo F25-EH Refrigerated Circulator is designed for precise heating and cooling applications, supporting both external temperature-control tasks and temperature-controlled applications performed directly within the bath. With a -28 to 150°C working temperature range, the F25-EH combines powerful heating and cooling with an integrated circulating pump to provide efficient heat-up and cool-down performance. The system offers ±0.03°C temperature stability, a 2 kW heating capacity, and cooling capacity up to 0.26 kW at 20°C, making it well suited for routine laboratory temperature-control applications.

Designed for straightforward laboratory operation, the F25-EH features a compact footprint, bright LED temperature display, PID temperature control, adjustable high-temperature cut-out, low-liquid-level protection, 1-point temperature calibration, and timer functionality. A removable venting grill provides convenient access for cleaning the refrigeration system to help maintain cooling performance, while the front-mounted drain allows bath fluid to be removed easily. The 4.5 L filling volume and circulating pump with flow rates up to 15 L/min provide flexibility for both internal and externally circulated applications.

All of our equipment is fully tested to perform at factory specifications before being shipped.

Recirculating Chiller Inspection and Recertification Checklist

• Inspect display for dimming or dead pixels and replace as necessary to maintain clear visual feedback
• Verify functionality of all buttons and input devices, ensuring reliable and responsive control
• Check that all external hosing connections are secure and properly installed to prevent leakage
• Test unit flow rate on a closed-loop system to confirm consistent fluid dynamics
• Examine all external surfaces for leaks, confirming a sealed and contained system
• Inspect internal components for any signs of leaks to ensure system integrity
• Verify power supply output for accurate voltage delivery per operational specifications
• Inspect all internal wiring, checking for any frays, tears, or compromised insulation
• Replace internal filters to maintain optimal fluid purity and system performance
• Confirm that the fan operates at proper speeds to provide effective cooling
• Verify compressor functionality for consistent performance and cooling efficiency
• Test cooling capacity, confirming it meets performance specifications at 20°C
• Measure water pump output to confirm correct PSI for stable fluid flow
• Determine the lowest achievable temperature, verifying against manufacturer standards
• Ensure cosmetic condition meets standards with no damage affecting functionality or aesthetics
