Hydraulic Oil Coolers

Model 2300/2500/2700/2800 Series

Shell and tube coolers that dissipate excess heat from hydraulic systems operating at high ambient temperatures.

Description

Shell and tube hydraulic oil coolers dissipate excess heat efficiently in hydraulically driven industrial and process equipment, including systems operating at high ambient temperatures. They share the 2300/2500/2700/2800 Series platform used for Thermex marine oil coolers.

Key features

2300/2500 Series: extruded aluminium bodies; 2700/2800 Series: cast aluminium bodies
Cast iron headers for freshwater cooling; 3-pass cooling as standard
90/10 cupronickel floating tube stacks
BSPT ports
Leak detection rings, standard on 2700/2800 and optional on 2300/2500
Viton seals allow operating temperatures up to 120°C
Options: gunmetal or glass-filled nylon headers, 1 and 2 pass configurations, and 70/30 cupronickel, 304 stainless steel or titanium tube stacks

Applications

Hydraulically driven industrial and process equipment
Hydraulic systems running at high ambient temperatures

Specifications

Duty range	3kW to 750kW (subject to flow rates and temperatures)
Max working pressure, oil side	20-30 Bar
Max working pressure, water side	10 Bar
Max operating temperature (Viton seals)	120°C

Ship Protection Systems (SPS)

Superconductor-based degaussing systems that mask a naval ship's magnetic signature against magnetic sensors and mines, at much lower weight than copper-based systems.

Equipment
