Bowman Engine & Transmission Oil Coolers are equally suitable for cooling torque converter, automatic transmission and engine oils. Being water cooled they have the advantage of freedom from accidental damage and also encourage quicker warming up of the oil, a feature which is particularly valuable in cold climates. The tube stack is fully floating so that thermal stresses are minimised and it can easily be removed should cleaning be necessary.

The GEA Bloksma plate fin oil (PF) cooler is a well proven, compact (25% of conventional), slim lined heat exchanger for cooling oil by means of sea- or fresh water and is suited for a wide range of marine and industrial applications. Unlike conventional shell & tube types it contains a bundle with a high density plate fin surface around the tubes. The cooler is available in 4 standard shell diameters ranging from 100 ñ 280 mm, covering 1 to 170 m2 plate fin surface. Connections in most cases can be DIN or SAE compatible or BSP threaded. The length of the cooler is variable. Standard components and modules enable to provide a large number of solutions, meeting customer requirements at a short delivery time.
Two standard versions are available:
* IV Industrial Version: For non-aggressive or controlled cooling water
* MV Marine Version: For aggressive or surface water

Plate heat exchangers
type PWT
The plate heat exchangers type PWT form an addition to our product range in the field of oil-water heat exchangers. In some cases they represent a cost-effective and space-saving alternative to the standard smooth pipe heat exchangers.
Description
Soldered plate heat exchangers are assembled from stamped special steel plates and connected by means of a copper shim and a special soldering process. Stamping creates a highly turbulent flow in the chambers between the plates, which enables excellent transfer of the heat. The type PWT plates stand out by their following characteristics:
Plates and connections made from special steel 1.4401
Connecting elbows and internal thread and keying surfaces.

Water 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.

Plate Heat Exchangers
Soldered and bolted plate heat exchanger
- PWT
- TL
Up to 30 bar oil pressure and from 25 to 3 000 l/min. oil flow. Operating temperature from -100 to +195 degrees. Soldered plate coolers are available from 10 - 200 plates. Bolted plate coolers are highly flexible and easy to clean thanks to the modular system.

Bolted plate coolers are ideal for sea water and specialist applications.
They are designed for use with special fluids or large capacity applications.
The main difference between the Brazed Plate and Bolted Heat Exchangers is that the Bolted Heat Exchangers have gaskets. A benefit of these heat exchangers is that they can easily be adapted by adding or replacing plates.
Flow ranges: 10-4600 m3/h
Working pressure: 10 - 25 bar
Temperature range: -20°C - +180°C

WATER-OIL HEAT EXCHANGERS WITH TUBE BUNDLE
They consist of small diameter smooth tubes; this allows the best compromise between high thermic yield and low pressure loss. For a good exchanger practices some oil rates are indicated in the tables. Going down to the lowest rate of flow, indicated in the tables, the low oil speed causes a great loss in yield, whereas a rate of flow which is superior to the maximum indicated, causes great pressure loss and does not considerably increase the thermal yield. The yield diagrams indicate the heat quantity each exchanger can disperse according to the difference between oil and water mean temperatures. Such diagrams assume the exchangers to be working with the maximum oil rate indicated in the table. With the minimum rate, the yield decreases by about 10%. Required water volume is a follows:
85 l/h for each kW to disperse with water temperatures (20°C)
170 l/h for each kW to disperse with higher water temperatures
