APV Hybrid Welded Heat Exchanger
With multi-flexible configuration for robust and efficient heat transfer
APV Hybrid Welded Exchanger
APV invented the plate heat exchanger in 1923 (Now SPX) and has continuously proven to be the preferred partner for heat transfer applications. By pioneering applicable technology in pressing, shaping, welding, sealing and testing steel, SPX has continued to develop and improve heat transfer technologies.
The company is committed to delivering an efficient and durable solution to ensure operational excellence, effectiveness and profitability.

SPX offers an extensive portfolio of plate heat exchanges covering many industrial applications. Regularly SPX heat exchangers replace older technology products due to the simplicity of installation and their high performance thermal characteristics. Whether recovering waste heat or isolating the cooling system from the cooling source, SPX has the application knowledge and product to improve efficiency and performance.

Choosing the Right Heat Exchanger
can be a Complex Matter

How can one single heat exchanger technology cover all your key priorities?


  • In a complex decision process, neglecting key priorities may lead to low performance or even plant failure ? things you would re-do if you could.
  • With more than a century of heat exchanger experience, SPX knows the needs and priorities of most industries.
  • Let SPX guide you through complex choices to the right solution for your specific application and needs.


What could happen if
you compromise here?
What can you expect
from SPX and Hybrid?
Very high working temperature, (including temperature shocks) Equipment failure/replacement Longer production uptime
Very high working pressure (including pressure shocks) Equipment failure/replacement Longer production uptime
Small Footprint High conversion/engineering costs Cost savings, accessibility
High heat recovery, extreme small log mean temperature difference Higher running costs Cost savings, lower CO2 footprint
Cleanability, manual and CIP Reduced efficiency Cost savings, accessibility
Resistance to corrosion Equipment failure/replacement Long service life


Based on a multi-flexible configuration platform, Hybrid is designed to operate under harsh conditions where other heat exchanger technologies can fail, have a shorter operating lifetime, or reduce operational efficiency. What?s more, easy access makes high-pressure cleaning of Hybrid plates simple, effective and fast!

The heart of the matter

The central plate core is contained by 4 movable pressure panels, and the 2 flows are separated by the plate wall and 4 corner bars.
