Did you know that even our smallest shell-and-tube heat exchanger has 54 possible interfaces between oil and water?

54 points where absolute precision determines safety.

That's precisely why Universal Hydraulik GmbH focuses on one thing without compromise:

➡ 100% Quality Control
➡ Maximum Operational Reliability
➡ No Media Mixing

🔵 Advanced Quality – Our Quality Promise

✅ Safe Coolers

4–5 tests per cooler – including automated testing procedures.

Every single shell-and-tube heat exchanger undergoes defined and documented testing steps:

1️⃣ Dimensional and Visual Inspection
Precision begins with the details – checking dimensional accuracy, material, and surface finish.

2️⃣ Tube Connection Testing
Special focus on the sensitive interfaces between the tube and tube sheet.

3️⃣ Hydrostatic Pressure Testing
Stress under defined test pressure – for maximum operational safety.

4️⃣ Separate leak testing of oil and water sides
Safe and permanent media separation.

5️⃣ Automated final inspection & documentation
Standardized, reproducible, and traceable.

✅ Clean Coolers

Cleanliness begins before assembly.

We perform welding and cleaning before final assembly.

This means for our customers:

✔ No weld spatter or welding dust in the system
✔ No bent tube sheets
✔ No additional oil flushing required

Cleanliness is not an add-on – it's part of our quality standard.

🎯 Our commitment: Zero tolerance for oil and water mixing.

Even the smallest leaks can cause efficiency losses, corrosion, or machine damage.

Quality isn't created at the end.

It's created in every single process step.

That's what Universal Hydraulik GmbH stands for.
