Hydropower Heat Exchangers and Bearing Oil Coolers
JEDHeatExchanger is a custom manufacturer of guide and thrust bearing oil coolers and shell and tube heat exchangers for hydropower generating equipment.
Units are manufactured from approved drawings, operating data, and project requirements for new installations and replacement projects.
Cooling Equipment for Hydropower Units
Hydropower generating units may use bearing oil coolers installed inside the oil tank or external heat exchangers connected to a pumped oil circulation system.
The suitable configuration depends on the bearing arrangement, oil circulation method, required cooling duty, cooling-water conditions, installation space, connection positions, and maintenance access.

Engineering Review Before Manufacturing
JED engineers work with the customer’s engineering team to confirm the design basis before production.
- Define the Starting Point: Review the available drawing, technical specification, existing unit information, or operating data.
- Confirm the Cooling Requirements: Check the working media, cooling duty, flow rates, inlet and outlet temperatures, and operating pressures.
- Review the Product Configuration: Confirm the heat exchanger type, materials, connections, installation space, and applicable inspection requirements.
- Approve the Manufacturing Documents: Production begins after the required technical details and manufacturing drawings have been reviewed and approved.
Project-specific drawings and application details are handled according to agreed confidentiality requirements.
Custom Units for New and Replacement Projects
JEDHeatExchanger supports both new equipment manufacturing and the replacement of existing coolers.
For New Equipment, please provide the available:
- Preliminary or approved drawing
- Cooler position and mounting arrangement
- Required cooling duty
- Oil and cooling-water data
- Flow rates
- Inlet and outlet temperatures
- Working and design pressures
- Allowable pressure drop, if specified
- Required materials
- Applicable codes and inspection requirements
- Required certificates and project documents
- Required quantity
For Replacement Units, please provide the available:
- Original drawing or dimensional sketch
- Existing cooler and nameplate photos
- Overall and mounting dimensions
- Access-opening or maintenance-space dimensions
- Connection sizes, positions, and orientation
- Existing materials, if known
- Working media and operating conditions
- Photos of damaged, corroded, or leaking areas
- Reason for replacement
- Required material or structural changes
- Testing and documentation requirements
- Required quantity
Any proposed change to the material, tube arrangement, cooler structure, or number of sections must be reviewed against the cooling duty, working conditions, and installation requirements.

Manufacturing, Inspection and Certifications
Our management systems are certified to ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018. Applicable Pressure Vessel, CCS, and ASME certification documents can be reviewed according to project requirements. VT, UT, and PT inspection by qualified personnel is available when specified.
Production Control
Materials, connections, critical dimensions, and assembly requirements are according to the approved manufacturing documents.
Inspection and Testing
Overall dimensions, mounting points, connection positions , and pressure or leakage testingare checked before shipment.
Project Documentation
Material certificates, inspection records, test reports, and other required documents are prepared according to the confirmed order .

FAQ
An initial review can begin with clear photos of the existing cooler, nameplate information, overall dimensions, mounting details, connection sizes and positions, and the available operating data.
However, the critical installation dimensions, interfaces, materials, and working conditions must be confirmed before the replacement manufacturing drawing is approved.
A material change may be possible, but it must a
Yes. A circular cooler may be divided into multiple sections when the access opening, lifting conditions, or maintenance space does not allow a complete single-piece cooler to be installed or removed.
The number of sections should be reviewed carefully because additional sections can reduce the size and weight of each part but also require more connections.
be reviewed against the working media, temperatures, pressures, water quality, corrosion conditions, and manufacturing requirements. The approved material will be shown in the final project documents.
Please provide the cooling-water source, inlet-temperature range, available pressure, and water analysis when available.
Information such as chloride or salinity level, pH, hardness, suspended solids, sediment conditions, and water treatment can help evaluate the materials exposed to the cooling water.
Yes, in some projects. The required mounting points, connection positions, orientation, and installation envelope can remain unchanged while the material or tube arrangement is reviewed separately.
Any proposed change must still meet the required cooling duty, pressure conditions, corrosion requirements, structural requirements, and available maintenance space.
Customer-specific or third-party inspection may be supported subject to project review.
The applicable standard, inspection scope, witness or hold points, required reports, and inspecting party should be confirmed before the order so that they can be included in the manufacturing and inspection plan.
