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 that should be treated as a “side effect” from running an evaporative condenser? [I am guessing your hand is still up]. Although scale buildup […]

Over the years of working in literally hundreds of compressor / engine rooms we have noticed a correlation between the cleanliness and neatness of the compressor room and the general operation of the refrigeration system. The neater the compressor room the better it works! Based on our experience here are a few things you can

We all know that refrigerant leaks cost money! The hissing sound of a leak is not so much SSSSSSSSSSSSSSS as it is $$$$$$$$$$$$$$$$! Let’s find and fix the refrigerant leaks in our systems. The first step is detection – we have to find the leak. For those of you that utilize ammonia as your refrigerant

This article will target refrigeration systems that utilize air cooled condensers, but the efficiencies to be gained apply to the users of evaporative condensers as well. First, let us remember a couple of important principles of refrigeration; 1) heat (energy) always flows from higher to lower temperatures, and 2) the function of the condenser is

You are receiving this notice because you are the owner / operator of a refrigeration or air-conditioning system that utilizes R-22 refrigerant and we want you to understand, and be prepared for, the rapidly rising cost of this refrigerant. BACKGROUND: The United States is bound by an international environmental agreement, called the Montreal Protocols that

The typical ammonia (and other refrigerants) leak detection system consist of one or more sensors communicating to a readout or display. Internal in the sensor is a “cell” that picks up the ammonia in the environment and provides the initial signal to the sensor electronics and ultimately to the readout device. This cell has a
