The role of a hydraulic cooler is to dissipate the losses in energy that occur in a hydraulic power unit which are primarily bought on by an abundance of system heat.
High system temperatures affect the viscosity of an hydraulic oil, its properties and lifespan and the hydraulic cooler works to keep these temperatures regulated and, in turn, help the system to run effectively and efficiently to help preserve its operational lifespan.
There are a variation of hydraulic coolers that help to keep system fluid temperatures in check and these include Air Blast, Off-Line and Water/Oil hydraulic coolers. Air Blast coolers are a cost effective solution that doesn't hold back on cooling power and suits those on a budget. Coolers that cannot be installed in the return line because of excessive pressure pulses are taken off-line, so the Off-Line Air Blast Cooler range is best suited to these types of application. Water/Oil cooler variants are ideal for hydraulic systems where space is an issue and a conventional hydraulic cooler won't fit. The case and core of these coolers are typically machined from extruded aluminium.
Selecting the right type of cooler for your system
Identifying the correct specification of cooler for your system takes into account several factors which we have detailed below:
– This can greatly affect a systems workload, with high temperatures making a system work harder, likewise with colder climates so a good balance must be found.
– Machinery often goes through various temperature cycles during its operational time, so you have to take this into account when choosing the level of cooling you require, i.e. high temperatures = more cooling needed.
– With the size and complexity of some bespoke systems, the amount of space required for the placement of an air cooler can vary largely. This is an area that should be looked at in detail during the planning phase of a system design so as to make sure that there is enough room to accommodate a cooler unit.
