SUMMER MAINTENANCE Well we did it. We finally are able to put away the snow shovels, snow blowers, hats and mittens. As the temperatures outside warm, not only do we feel it on our vitamin D deprived skin, but so do our home Air Conditioners and commercial and industrial refrigeration systems. Carlson & Stewart Refrigeration […]

Condenser Drop Legs Last week I had the opportunity to attend a RETA Safety Day. At this meeting I listened to a presentation on purging non-condensables and it reminded me of an important design aspect when designing/installing the piping for ammonia condensers. The situation I am thinking about primarily concerns installations involving multiple condensers, or

The focus this month is a brief look at the American Innovation and Manufacturing act or AIM act for short. This policy seeks to dramatically reduce the usage of HFC refrigerants with the target of a 85 percent reduction by 2036. The goal of the policy is to reduce the amount of refrigerant with high

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
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
