Gasket Free BPHE vs PHEBPHE advantage
Size - Large BPHE Units occupies less than half the footprint of corresponding PHEs.- A PHE weights at least twice as much
Operational reliability
- Elimination of gaskets ensures unparalleled up-time and maintenance costs. - Fixed plate package means stable performance
Maintenance need and LCC
No gaskets or studbolt mean no maintanance for tightening plate package or servicing gaskets
Every unit is factory assembled and helium tested
At least 50% reduced weight and footprint
Installation in China, corresponding units

• District Heating PHE 1800 kW
• Price for exchange of gaskets:
€ 7500 (Pending)
• District Heating BPHE 1800 kW
• Price for a new BPHE: €5800
MODULAR CONCEPTS OFFERINGS WITH BPHE
Redundancy
• N + 1 is simply one more module rather than an additional
separate PHE
• Saves space, investment cost and less risk of total failures
B649 makes increased redundancy possible to a lower cost and footoprint!
Example 540 TR
• Traditional Design:
– 540+540 = 1080 TR
– If one unit fails: 540 TR is available
– If 2 units fail: System down!
• N+1 Design:
– 270+270+270 = 810 TR
– If 1 unit fails: 540 TR is available
– If 2 units fails: 270 TR available
Capacity extension to 3000 kW – B65Lx196 to B65Lx218

People’s Hall of China, Beijing:
- District Heating installation since late
90’s
- 6 BPHEs connected in parallell
supplying spce heating to the building
complex
Genyuan International Center, China
• The Genyuan International Center is
situated in east China.
• SWEP's BPHEs are used for:
– Centralized heating & tap water
– District Cooling
– Free cooling
– Pressure breaker
Karolinska Hospital, Stockholm
• The design and construction of Nya Karolinska
Sjukhuset (NKS) started 2010 and the first
phases were equipped with the traditional
Gasketed Plate Heat Exchanger (PHEs)
• Operational dependability and low Life Cycle cost
was a determining factor to go for BPHEs
• In phase 4 & 5 at total of 150 SWEP BPHEs have
been supplied so far.
