Automatic Filters

AutomaticFiltersMAHLE automatic filters optimize production processes and work extremely efficiently. They can be used without interruption in many industrial areas, which include machine and plant construction, the automobile industry, marine applications and extraction technology as well as different areas in the chemical, paint and foodstuff industries.

The Mahle Automatic Filter range includes:

  • Vario Automatic Filter Series
  • Automatic Metal Edge Filter
  • Automatic Filters with Internal Pressure Segment Cleaning
  • Automatic Filters with External Pressure Segment Cleaning
  • Automatic Filters with External Pressure Segment Cleaning with continuous Filtrate Flow
  • Automatic Filters with Scrapers and External Pressure Segment Cleaning

Mahle has recently acquired Mahle - AKO who offer fully automatic reverse flow filters ideal for large flow rates up to 3000 cubic metres per hour.

  • Simplex and change-over sieve basket filters
  • Duplex Basket Filters
  • Backwash Filters
Liquid/liquid Separation

LiquidSeparation-250x153Mahle-NFV is a quality and technological leader for mechanical processes in filtration and separation and allows us to offer the following services:

  • Oil Treatment
  • Fuel Treatment
  • Bilge Water
  • Process, water
  • Ballast Water
  • Cooling water
  • Emulsions
  • Membrane Filtration (Nano, Ultra, Micro and Reverse Osmosis)

The industrial filter range comprises filters and filter systems, equipment and accessories for fluid engineering, de-dusting equipment and systems, as well as automatic filter systems for coarse filtration through to the absolute filtration of fluids and pastes as well as for the homogenization of foodstuffs.


The coolers are designed for use in different environments and are suitable for a wide variety of applications and industries. The air blast coolers are available with AC, DC or hydraulic motors and our complete cooler range includes heat exchanges, water oil coolers, industrial chillers, cooling & filter systems, oil filters and circulating pumps.

Air Blast Coolers

AirBlastCoolersFree cooling medium

When fitting an air oil cooler in your system, the cooling medium will always be free and available. Oiltech air oil coolers are designed to resist high pressures and to provide maximum cooling capacity with regard to oil viscosity and specific heat. An air oil cooler is especially suitable for outdoor applications as an air oil cooler can never ice-up.

Using surplus energy
The air oil cooler is used in mobile as well as in industrial systems, where the cost to pipe water to a water oil cooler is high or where water is scarce. The surplus thermal energy transferred from the oil to the air can be used to heat premises and the fan can be used for ventilation.

Very important component
The fan is a very important component in air oil coolers. To offer the best possible cooling capacity, our fans are designed with different numbers of blades and blade pitches. Balancing is carried out before the fan is fitted into the cooler to ensure high performance.


Plate Heat Exchangers

PlateHeatExchangers-150x180Water oil coolers are used in many stationary hydraulic and lubricating systems to optimize the oil temperature. Water oil coolers are especially suitable in environments where water is easily accessible. The extremely quiet water oil cooler is ideal for indoor use where the cooling water cannot ice-up. The surplus energy from the heated cooling water can for instance be used to heat other water.

Off-line cooling and oil filter system

In all modern hydraulic systems, off-line oil cooling and filtering is becoming increasingly popular as the system can operate around the clock independently from the main system to avoid differences in pressure and flow conditions.

We supply both brazed plate and bolted plate heat exchangers. The main difference between these two propducts is that the bolted plate products have gaskets which enables you to change the plates easily.

Water Oil Cooler Products

  • Brazed Plate Heat Exchangers (PWO)
  • Brazed Plate Marine Heat Exchanger (PWO-M)
  • Bolted Plate Heat Exchanger
Industrial Chillers

IndustrialChillersThe HLA range of air cooled water chillers offers the most advanced design to satisfy today's industrial cooling equipment requirements.

The entire range is packed with the latest technology and assembled with components developed with our world-renowned manufacturing partners including Maneurop, Danfoss, Siemens and Grundfos.
