Ammonia Refrigeration: What you really need to know

December 13th, 2017

Ammonia often gets a negative reputation because it can be dangerous to work with, which often makes decision makers immediately write it off as an option when considering a new industrial refrigeration system. Find out why it can be a reliable option for many industrial refrigeration applications with the infographic explaining what you really need […]

As Room Temperatures Go Down, Refrigeration Costs Go Up

November 21st, 2017

In general, compressor energy use increases about 2% per degree that suction temperature is reduced. In addition, there is more room thermal loss, infiltration and defrost penalty. When you include all factors, one could assume about 2.5% penalty per degree reduction in room temperature set point. So, reducing a room from 0°F to -10°F would […]

The Benefits of Lowering Condenser Pressure in your Refrigeration System

September 13th, 2017

The selection of a lower condensing head pressure is one of the best ways to reduce energy costs in an ammonia refrigeration system. The larger condenser saves money all year round; and, at the same time increasing the tons of refrigeration produced by the compressor. Therefore, more tons at a lower brake horsepower per ton […]

Pros and cons of ammonia vs cascade

June 20th, 2017

The frozen food processing industry is striving to minimize or eliminate HCFC and HFC refrigerants, reduce ammonia refrigerant charge and look for alternative natural refrigerant options with similar or better energy efficiency. One attractive option is an ammonia/carbon dioxide cascade refrigeration system. Visit the link below for comparisons of two traditional ammonia systems—single-stage economized and […]

Ammonia/CO2 South of the Border

May 18th, 2017

Mexican cold-storage operator Frialsa is leading its country’s adoption of NH3/CO2 systems that are safer and 15%-20% more energy efficient than conventional ammonia equipment. Two natural refrigerants, ammonia and carbon dioxide, have each proven to be highly effective working fluids, NH3 favoring the industrial sector, CO2 the commercial sector. But a growing number of end […]

Refrigeration Technology Provides Multiple Routes To Frozen Food Profitability

March 31st, 2017

Cascade systems and more efficient blast cells can lower the cost of freezing food products. Refrigeration is a necessary expense for most perishable food and beverage products. Given foods’ margin pressures, controlling and possibly reducing refrigeration costs can mean the difference between profit and loss. Fortunately, technology is providing remedies to the cost squeeze. In […]
