Hydraulic Coolers

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:

Environment – 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.

Temperature cycles – 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.

Space 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.

  • Why choose Hydraproducts as your component supplier?
  • Manufacturers

Hydraproducts has a large stock holding of components we are able to support irregular customer requirements. If you have regular needs then we are happy to hold bonded stock to smooth out production/supply fluctuations.

Supporting our customers with the comfort that our engineers have been using these components to build hydraulic systems in our own workshops for over 15 years. Our Technical Sales engineers can help and advise on product choice as well as identifiy and cross reference a wide variety of other hydraulic equipment manufacturers.

Key manufacturers 

OMT - Based in Italy, OMT has become a world recognized manufacturer of Hydraulic components. A recent acquisition of Luen, Hydraulic cartridge Valve manufacturer, has strengthened the group within mobile and industrial markets. 

OT - With a engineering pedigree in Italian gear pump manufacturing, this company produces some the of the finest Aluminium hydraulic Gear pumps available today. They are customer focused with a very reactive production philosophy.

TEC - Tec motors have become the largest reseller of AC induction motors in the  UK. Hydraproducts has fitted the TEC (TECHTOP) motors to our power packs and power units for over 15 years, so we know the quality is well suited to this market palce.

  • More about Micro Power Packs
  • Typical Applications

The HPU micro power pack has a single acting hydraulic circuit, the check valve and solenoid valve hold the cylinder load up. A high quality hardened steel check valve insert ensures low leakage and excellent load holding. Versions with Normally open/closed solenoid check valves and low noise check valves are available.

All of these micro hydraulic power packs have a precision engineered aluminium manifold that houses the hardened steel valves. A carefully developed micro hydraulic pump gives pressures up to 200bar. Each manifold has an integrated 90 micron filter element, ensuring all micro hydraulic systems are protected and give a long service life.

To drive the hydraulic pumps we offer DC motors from 150 to 800Watt, in 12V and 24VDC. 150 and 250Watt Fractional Horsepower AC motors as well as standard IEC frame AC motors from 0.18kW to 0.37kW.

Pump sizes range from 0.17cc to 1.48cc/rev.

Tanks from 0.1 to 1 Litre, all of which can be in vertical (tank uppermost) or horizontal orientation.

Typical applications include :- 

    Mobility lifts where Wheelchairs are lifted from vehicles
    Micro power packs for through floor lifts.
    Door and gate opening actuators

Hydraproducts offers its worldwide OEMs and distributors reliable products through design and manufacturing expertise. The quality of in-house design, manufacturing and experience in micro hydraulic power units ensures a match to your requirements.
