In the air cooled oil cooler market, there is a perception that fans with plastic blades are prone to breakage and only metal blade fans should be used. This leads customers to choose more expensive metal blade fans, even when plastic blade fans would suffice. The material of the fan blade itself does not determine its reliability. We’ve seen plastic blade fans for years. Fan blade breakage happens when the design is unreliable, regardless of blade material. Jumping to conclusions about material without considering design is a costly mistake. Our AL-608 air cooled oil cooler uses speci ..read more

      Introduction In the world of mechanical manufacturing, the performance and longevity of machinery play a crucial role in determining the success of an organization. One key factor that often goes unnoticed but can significantly impact machine efficiency and lifespan is the temperature of the oil used for lubrication. When oil overheats, it not only compromises lubrication but also leads to increased wear and tear, reduced equipment life, and higher energy consumption. However, by integrating an optimum air oil cooler into their operations, organizations can unlock a range ..read more

“I am looking for an Air Cooled Heat Exchanger Manufacturer who will give me an inexpensive oil cooler” We were recently approached by a hydraulic equipment manufacturer for a quote on an Air Cooled Oil Cooler. When we asked him for details about his application, his answer was “Just give me any inexpensive oil cooler.  Actually, I don’t need one as I am using a large tank of 750 liters. I just need to complete the bill of materials to satisfy the customer”. For us, this is not an uncommon response. On a little prodding, he disclosed that his hydraulic system used a 75 HP motor coupled t ..read more

Air cooled heat exchangers, are used to cool a hot fluid using cool ambient air. The hot fluid is passed through the heat exchanger & cool ambient air is used to cool it down. The ambient air drawn in from the environment by using a fan. The fans are usually driven by an electric motor. Typically in industrial application the fan motor is AC (single or three phase), whereas in mobile or vehicle mounted applications these fans run on a battery & usually are 12V or 24V DC operated. These coolers are known by various names in the industry – fin fan heat exchangers, fan cooled heat e ..read more

In my 30 years of working in the Industrial Hydraulics industry, I have visited over 1500 units & done over 500 machine failure analysis. There are two primary root causes of failures that dominate over all the rest put together. Oil Contamination Oil Heating A lot has been said & written about oil contamination & its control – changing the oils, oil filtration, flushing the system, air breather selection. Today, I am going to talk about the second – Oil Heating & its control. Before we do that lets first look at the primary reason why oil heats up. During my training session ..read more

Do centralized oil lubrication systems need oil cooling? The purpose of installing a centralized lubrication system is that the lubricating oil is stored in a common reservoir and it is sent to various parts of the same equipment OR various equipment’s, with the primary objective of : Lubricating Heat removal To remove the debris that has got generated because of mechanical wear & tear Therefore it is imperative that centralized oil lubrication systems supply cooled, filtered oil so as to efficiently lubricate & cool various bearings, bushes, gears & other rotating parts in the p ..read more

Do gearboxes need oil cooling? The primary purpose of the lubricating oil in a gearbox is: To Lubricate To remove heat To remove the debris that has got generated because of mechanical gears meshing together and working. If the temperature of the oil is high, it will not be able to remove the heat that is getting generate. Plus, as the temperature rises, the viscosity of the oil drops and it’s ability to lubricate properly is reduced. A drop in viscosity also reduces the buoyant force of the fluid. This in turn reduces its ability to carry away debris. Most large continuous duty gearboxes do ..read more

The primary purpose of Air Cooled Heat Exchangers in a gear box is the lubrication of the mechanical moving parts, gears, bearings, bushes. Adequate lubrication ensures that wear & tear is minimized.  As oil heats up, its viscosity gets reduced & its ability to lubricate is compromised. As a result the temperature keeps rising. Resulting in reduced lubrication & further heat generation. Eventually leading to increased wear & tear and reduced equipment life. The rate of progressive wear and tear will increase rapidly. As wear and tear takes place, mechanical efficiency drop ..read more
