Process Cooling Systems/Bearing Lube Cooling Systems/Turbine Lube Systems
Every industry has its unique challenges, but virtually all industries share the goals of increased machine uptime, reduced maintenance, improved safety, energy savings and lower total cost of ownership. Having a reliable machine lubrication system is vitally important. Bearing life is often much better when the bearing is kept clean and well lubricated. However, many applications make good maintenance difficult.

Process Cooling System
Process cooling systems provide cooling fluid to a process function. The process starts with the reservoir; it provides some heat transfer, however the majority of cooling starts with heat exchangers. Heat exchangers remove heat from a system by transferring the heat to another media (water or air). Types of heat exchangers may include fan, shell & tube, plate or refrigerated and vary in cost and efficiency. Typically, multiple pumps are used to prevent a single failure from shutting down the system.
Bearing Lube / Cooling System

Bearing lubrication and cooling skids provide a source of cool clean oil to remove heat from bearings. This extends the life of the system and prevents cost breakdowns. Lube systems typically have the following:
Lube pump and optional backup lube pump
Gravity return ports
Low and kill Level switches
High and kill temperature switches
Output pressure switch and gauge
Turbine Lube System
Turbines require bearings for support during operation. Each of these bearings are supplied with hydraulic oil for lubrication. Hydraulic Lubrication systems are crucial if turbines are to have a long and productive life. However, the oil itself needs to be kept at the right temperature for effective lubrication. EHA-manufactured hydraulic lubrication systems are designed to keep the oil at the right temperature. They typically feature the following components:
- Lube Reservoir that contains the cooling oil for a turbine based pump.
- Electrical emergency backup pump that provides pre-startup lube flow and backup flow in the case of a main turbine pump failure.
- Low & high pressure switches – Learn more about pressure switches for lubrication systems.
- Dual Lube filtration with dirty filter indicators – Lean More
- Pressure gauges before and after main filtration give a visual indication of the pressure
- High Temperature switch and gauge
- Water-to-Oil heat exchanger with water saving and temperature regulation valve
- Lube temperature gauges before and after heat exchanger
- Oil sample port - for easy lab sampling of oil
- Fluid Level indicator
- Turbine Pressure regulator
- Turbine suction and gravity return ports
