Reliable Cooling Redundancy

Each FZ series freezer includes multiple, independent thermoelectric cooling units. The 7 year warranty on cooling components and the ability of our chambers to maintain temperature, even if the chamber suffers multiple failures, is unmatched by any other refrigeration-based chamber.

Widely Proven, Non-Proprietary Controllers

Standard controllers for the FZ Series are manufactured by Fuji Electric and are ideal for laboratory freezers. Unlike many proprietary controllers, this controller is commercially available and proven in tens of thousands of installations. Standard functions include: autotuning, fuzzy logic, PID control, programmable alarms, calibration capability, offset capability, etc. A touchscreen control interface is optional. Other controller manufacturers are also supported (Watlow, Allen-Bradley etc.)

Greatly Reduced Direct and Indirect Energy Loads

The FZ Series freezers utilize less energy than comparable incubators and introduce less impact upon building cooling systems. This efficiency “dual benefit” allows our chambers to be located in spaces unsuitable for other chambers.

Services and Warranties

We offer 24 hour technical support throughout the lifetime of your freezer. In addition to standard warranties, we also offer extended warranties for cooling components, parts and labor. We also provide qualifications, validations and preventive maintenance services at an additional cost. Please ask for a quote.
