Dear Valued Customer, The International Institute of All-Natural Refrigeration (IIAR) has a suite of standards that help establish both code for central ammonia refrigeration systems, but also generally accepted industry practices. Up until recently, this suite of standards largely focused on new systems or modifications to systems as well as maintenance and operations of […]

Ammonia safety relief valves come in many different shapes and sizes. Similarly, there are also many different manufacturers of them as well. Most of these manufacturers disclose a “shelf life” but none of them disclose a “service life”. This is because it really isn’t within the manufacturers purview to direct on this but rather it

Earlier this month, the EPA announced its final ruling on Technology Transition Rule portion of the AIM Act, which will phase down hydrofluorocarbons (HFCs) in several industries. According to the act, the primary goals are to reduce emissions of climate damaging HFCs

As CO2 gains more traction in our industry, our customers will ask what the advantages of CO2 are over ammonia and synthetic refrigerants. I feel this article (while it drills into the thermophysical properties quite a bit) helps clarify the advantages and disadvantages of one of the re-emerging refrigerants in our industry, CO2. Please contact

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.

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

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
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

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

As summer approaches I thought it would be a good idea to revisit one of our previous blog postings from a few years back… How many of you have “scale” on your evaporative condenser? [I am guessing your hand might be in the air]. How many of you feel that this is “normal” and something
