Technical Specifications
：
Part Number: HB400-50002
Compatible Models: Industrial machinery/hydraulic systems needing HB400-50002 (check manual)
Function: Transfer heat between fluids to control equipment temp
Core Material: 316L stainless steel (3mm thick, 16 flow channels)
End Plate Material: Carbon steel + epoxy coating (5mm thick)
Sealing Material: EPDM rubber gaskets (max 284°F/140°C)
Heat Transfer Efficiency: ≥ 85% (tested with water-water)
Max Temp: 400°F (204°C)
Max Pressure: 150 PSI
Dimensions: 18.5" (L) × 8.2" (W) × 6.3" (H) (same as original).
Installation: Direct replacement-uses existing bolt holes, no extra tools.
Fits compatible machines-no extra work, just like the original.
Core is 316L stainless steel: doesn't rust from most industrial fluids (mild acids, salts included) and handles up to 400°F (204°C) without bending.
End plates are carbon steel with epoxy coating-tough, no rust. Seals are EPDM rubber gaskets: take up to 284°F (140°C) and won't leak after long use.
Key Features：
Good heat transfer: 316L core works 15-20% better than regular carbon steel.
Rust & heat resistant: 316L handles up to 400°F; epoxy-coated plates don't rust.
No leaks: EPDM gaskets seal tight, even at 150 PSI.
Perfect fit: Same size as original-bolt right in, no drilling.
Stands up to shaking and wear.
Application ：
Only fits equipment that uses part number HB400-50002 .
Before buying, check your equipment's model and part number-it won't work with other heat exchangers or brands that don't match.
Maintenance Recommendations
To keep it working:
Flush the core every 6 months (use low-pressure water or mild soap)-dirt makes heat transfer worse.
Check EPDM gaskets every 3 months for cracks-replace if they're worn.
Inspect end plate coating yearly-touch up with epoxy paint if it chips.
If cooling/heating gets worse or there's a leak, replace it fast-waiting will damage your equipment
Quality Assurance ：
Every HB400-50002 goes through 3 tests before shipping:
1) Pressure test (150 PSI for 30 mins, no leaks);
2) Heat transfer test (needs ≥85% efficiency);
3) Check that core, plates, gaskets are correct.
It's as reliable as the original-keeps your machinery running smoothly.
