Drawing-Based Custom Water Coolers | Marine & Industrial | VRCOOLER
For naval architects, marine shipyards, heavy machinery OEMs, and industrial plant operators requiring precision-matched thermal equipment, VRCOOLER manufactures custom water coolers and heat exchangers directly from customer engineering drawings, 3D CAD models, or physical sample units. Operating advanced CNC machining centers and automated orbital welding facilities, VRCOOLER produces complete shell-and-tube coolers, standalone replacement tube bundles, and air-to-water heat exchangers engineered to exact blueprint tolerances. Backed by marine-grade and industrial metallurgy (including CuNi 90/10, 316L Stainless Steel, Titanium Gr. 2, and Heavy Carbon Steel), VRCOOLER drawing-based water coolers guarantee 100%100% dimensional interchangeability, compliance with ASME/TEMA standards, and competitive factory-direct lead times.
Build-to-Print Capabilities for Marine & Industrial Sectors
Standard off-the-shelf heat exchangers rarely match the exact nozzle orientations, footprint constraints, and mounting bolt patterns of specialized marine vessels and complex industrial skids. VRCOOLER bridges this gap through flexible build-to-print (BTP) manufacturing:
Supported Input Formats:
2D Engineering Blueprints: Manufacturing directly from AutoCAD (.dwg / .dxf), raster PDF drawings, and scanned legacy paper schematics.
3D Solid CAD Models: STEP, IGES, SolidWorks, and Inventor files for full clash detection and exact piping nozzle alignment.
Worn-Out Physical Samples & Nameplates: Reverse-engineering from decommissioned units using 3D laser coordinate scanning and metallurgical material verification (PMI).
Thermal Performance Datasheets: Sizing and complete structural mechanical detailing based on your fluid flow rates, temperature profiles, and allowable pressure drops.
Comprehensive Cooler Types Manufactured from Drawings
At VRCOOLER, our flexible fabrication lines accommodate all major heat exchanger architectures:
1. Marine & Industrial Shell-and-Tube Coolers
Configurations: Fixed Tubesheet (TEMA BEM/AEM), Removable U-Tube Bundles (BEU/AEU), and Floating Head Coolers (AES/BES/Type OP).
Applications: Marine main engine jacket water coolers, gearbox lube oil coolers, marine central cooling systems, and hydraulic power unit (HPU) heat exchangers.
2. Generator & High-Voltage Motor Air-to-Water Coolers (TEWAC / CACW)
Configurations: Top-mounted, side-mounted, and curved radial stator pit cooler banks manufactured to exact arc radii and duct flange bolt holes.
Safety Options: Concentric double-tube leak detection systems with integrated moisture alarm chambers.
3. Standalone Replacement Tube Bundles
Complete replacement bundles (tubesheets, baffles, tie rods, and expanded/welded tubes) designed to slide directly into existing shell casings with sub-millimeter clearance precision.
4. Marine Box Coolers & Keel Coolers
Immersed U-tube bundles engineered for direct hull installation on tugboats, fishing trawlers, dredgers, and coastal workboats.

Frequently Asked Questions (FAQ)
Q1: What information is needed if I only have a damaged sample cooler and no drawings?
A: If original drawings are missing, you can provide key field measurements (outer diameter, overall length, nozzle sizes, and port centerlines) along with photos of the unit and nameplate. Alternatively, you can send the physical sample to VRCOOLER for 3D laser coordinate scanning and reverse engineering.
Q2: How does VRCOOLER ensure the replacement cooler will fit into our existing piping?
A: VRCOOLER generates a detailed 2D CAD approval drawing matching all critical connection interfaces (flange standards, nozzle projections, and mounting foot hole centers) for your formal verification and sign-off before steel cutting and machining begin.
Q3: What marine classification society certifications can VRCOOLER support?
A: VRCOOLER fabricates heat exchangers in full compliance with major international marine classification society rules (such as CCS, DNV, BV, ABS, and Lloyd's Register) upon project request.
Q4: Can VRCOOLER upgrade the tube material while keeping the drawing dimensions unchanged?
A: Yes. If your original copper or carbon steel cooler failed prematurely due to aggressive river water or seawater, we can upgrade the tube bundle to CuNi 90/10, 316L Stainless Steel, or Grade 2 Titanium while maintaining the exact external dimensions of your drawing.
