Ice Builders…Still Relevant? Have you ever seen one of these big ole rectangular tanks [usually outside] with a surge drum on top and the tank is full of water? These hulking pieces of equipment might just be an ice builder and in many cases it plays an important role at a food processing […]

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
Honeybee’s By Chris Savage You might be thinking, why the heck would there be a blog post on a refrigeration website about honeybee’s? Up to about a month ago, I would have been thinking the same thing! Recently Carlson & Stewart Refrigeration was contacted by a local, South Dakota, honey producer. He called with some

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
