Hazard Analysis By Chris Savage Most of us in the ammonia refrigeration world are aware of the OSHA and EPA compliance guidelines. You are familiar with PSM (Process Safety Management) by OSHA and the RMP (Risk Management Plan) by the EPA. These 2 programs are very similar, with only a few minor differences. But the […]
Hydrocarbons such as Propane, Propylene, and Isobutane are great natural refrigerants that are successfully used in commercial refrigeration appliances today. Hydrocarbons can boast the low global warming potentials regulators are looking for without being Ozone depleting. So why don’t they get as much airtime as other natural refrigerants such as ammonia and CO2? Perhaps the

10/6/2022 Author: Erik Hansen Condenser Piping I recently completed a visit to a facility I have never been to before in Colorado. The end-user had hired a 3rd party engineering firm to perform an energy balance for their central ammonia refrigeration system. The end-user viewed the report and took at face value which is
An important part of the refrigeration design process is determining what size refrigerant lines returning to a compressor or an accumulator/recirculator vessel should be. These return lines are often simply called suction lines and are sized based on the tonnage of the refrigerated load. Recommended pipe size will change based on tonnage as well as

June 2022 Blog Post Author: Erik Hansen Subject: Stainless Steel Condenser Tubes or Galvanized? That is the question! NOTE: The posting will dig a little into product selection revolving around evaporative style condenser products and not necessarily air-cooled or adiabatic condensers. Industrial refrigeration systems in the Midwest often use evaporative type condensers for

Moisture Control By Chris Savage Moisture control…..what does that mean? Relative humidity, dew point, condensation, evaporation, dry bulb, wet bulb, enthalpy, specific volume, humidity ratio, vapor pressure, dehumidification, desiccant, reheat, grains of moisture…..these are all terms that you might come across when you start talking about moisture control. If any of this terminology is unfamiliar
If you have ever been involved in buying or installing a new evaporatively cooled condenser, then you’ve probably heard about evaporative condenser passivation. You probably heard it is important and a process you should strive to complete. But if you are like many owners, operators, or heck even refrigeration engineers, that’s probably where your knowledge

Those of us in the northern climates are familiar with the cruel outside conditions. Old Man Winter lets loose his cool breathe and our backyards and driveways become frigid winter lands that make us always think…“why the hell do I live here again?!” Those of us in the northern climates and familiar with central ammonia
