Alfa Laval, the world-leading supplier of compact heat exchangers, is launching new brazed heat exchanger models to match the natural next step in the design of CO₂ systems. AXP27 and AXP52 high-pressure heat exchangers provide efficient heat transfer while saving space and weight.

Expanding Alfa Laval’s range of high pressure-rated brazed plate heat exchangers, AXP27 and AXP52 units can withstand operating pressures of 130 bar with thin and compact external frame reinforcement. They were specially designed to fulfill customers’ needs when using CO₂ as a refrigerant in subcritical and transcritical applications. A patented stainless steel construction significantly cuts down the amount of materials used and reduces space requirements.

AXP27 and AXP52 brazed heat exchangers for transcritical CO₂ were specially developed to meet the needs of the medium capacity range for the commercial refrigeration and heat pump markets. The application spectrum for these heat exchangers is wide and covers CO₂ heat pump hot water systems, CO₂ supermarket chiller installations, and commercial air conditioning systems. The new heat exchangers are designed to cover heat recovery duties, gas coolers, condensers, sub-coolers and suction gas heaters.

With their efficiency, reliability, safety, heat recovery capacity and low environmental impact, the new range represents a whole new generation of heat exchangers.

“The market for commercial refrigeration with CO₂ is developing rapidly,” says Rolf Christensen, Senior Product Portfolio Manager, Industrial Equipment at Alfa Laval. “An increasing number of supermarket chains decide to install refrigeration equipment with natural refrigerants like CO₂ as it turns out to be a sustainable and efficient refrigerant, especially when considering heat recovery. It may also reduce the supermarket’s CO₂ footprint substantially”.
