This is not a single innovation but many innovations working together. It is a reflection of today's most powerful engineering and a commitment to the belief that anything is possible.

Full Color Touch Screen Display

Our color touch screen display gives you all the information you need at a glance. The screen will display continuous status of set temperature, actual temperature, reservoir fill level and output pressure as well as the status of your air filter. System messages are provided in easy to read text instead of confusing error codes.


These high-performance chillers utilize our exclusive patent-pending noise reduction system. The WhisperCool® system evaluates the demand for cooling from the application then slows the fan speed to the minimum necessary to achieve control point, making the chiller extremely quiet while maintaining optimal temperature control at the same time.

Front Fill Reservoir

DuraChill® Chillers offer a conveniently located front fill reservoir. You no longer have to go to the back of the chiller to open and fill the reservoir. DuraChill® has the fill port in the front, making it easy to access, avoiding spills and saving time.

Continuous Liquid Level Monitoring

Because pump seals will fail in as little as 30 seconds of being run dry, DuraChill® chillers include a state-of-the-art capacitance liquid level sensor to protect the pump from premature failure. If the fluid level becomes low, the DuraChill® chiller will give you visual and audible alarms and if the fluid level reaches a point where there’s a risk of pulling air into the pump, DuraChill® will shut the chiller down and present another alarm.


A highly optimized refrigeration system allows us to use less refrigerant than ever before, reducing the environmental footprint of the chiller. Everything in the DuraChill® line of chillers has been engineered for the future migration to natural, low global warming potential refrigerants: Isolation of power components, non-sparking relays and forward-thinking design go beyond current environmental guidelines.


DuraChill® is preprogrammed to change its own air filter once a month for a two year period and the change interval can be adjusted to suit your operating environment. This will dramatically reduce downtime and unnecessary service calls and relieve you of the burden of preventative maintenance on your new DuraChill® chiller.

UV Light Biological Growth Inhibitor

As a part of our commitment to the environment we developed a patent -pending UV Light Biological Growth Inhibitor that will continuously control biological growth in the fluid path without the need to add chemical growth inhibitors and preventing algicides from being released into the world’s waterways.

Intelligent Self Diagnostic System

DuraChill® features an Intelligent Self Diagnostic system that allows each DuraChill® chiller to store its complete initial operating performance profile in onboard on the day it is built. At any time, users can initiate the Self Diagnostic System to compare current performance against data stored on the day the chiller was first manufactured allowing for quick and definitive troubleshooting of performance issues.
