Alfa Laval AXP stands for “extreme pressure,” and that’s exactly what these brazed plate heat exchangers are designed to handle. Specifically engineered for subcritical and transcritical applications using CO2 (R744) as a refrigerant, the AXP line can also support other fluids that require very high pressures. AXP units are suitable for duties ranging from heat recovery, condensing and sub-cooling to gas cooling, suction gas heating and more.


More with AXP

  • Highly resistant to corrosion and extreme pressures
  • Compact design enables simple, cost-effective installation
  • Certified to handle pressures up to 167 bar (PED approval) and 2233 psi (UL approval)
  • Also available as an evaporator with an add-on distributor as well as in full stainless steel for ammonia/CO2 cascade systems
  • Small hold-up volume and lower refrigerant charge provide rapid response to temperature changes
Pressure peaks and rapid temperature changes subject heat exchanger materials to physical stress, eventually leading to problems that can cause equipment failure. With extensive experience in thermal transfer technology, Alfa Laval has studied these phenomena in order to produce a resilient brazed plate heat exchanger that can provide a long service life under high operating pressures. The result of this development, our AXP line, has PED-approval for maximum pressures of 167 bar at 90°C and UL-approval for 2233 psi at 400°F. This makes AXP highly suitable for applications using CO2 as a refrigerant, such as hot water heat pumps, supermarket chiller installations and commercial air conditioning systems.

The easy way to reduce your energy costs and increase energy efficiency

A refund is just the start of your savings potential with the new exchange programme. Alfa Laval’s innovative heat exchanger technology will significantly increase the energy efficiency of your processes.
