AlfaQ
Alfa Laval AlfaQ™ heat exchangers are used for HVAC applications such as district cooling substations, ice-storage systems, data centers, and free cooling systems. The range is certified according to the AHRI Liquid to Liquid Heat Exchangers (LLHE) Certification Program which ensures thermal performance according to manufacturers’ published specifications. AHRI certification is the only global, third-party performance certification for plate heat exchangers.
AHRI performance certification
The Air Conditioning, Heating and Refrigeration Institute (AHRI) certification is an independent, third-party verification of thermal performance. Through its certification program and standards, AHRI strives to help customers save energy, improve their productivity and help to ensure a better environment.
AHRI Liquid to Liquid Heat Exchanger (LLHE) Certificaiton Program ensures that the product performs in accordance with manufacturers' published specifications, and is particularly useful in applications such as district cooling substations, ice-storage systems, data centers and free cooling systems.

Well-designed and long service life
Alfa Laval AlfaQ™ gasketed plate-and-frame heat exchangers are available to meet most heat transfer requirements – whether large or small – demonstrating our commitment to optimizing the performance of our customers’ processes.
Equipped with well-designed features the heat exchangers are easy to maintain and have a long service life. Some of the features available include:
- ClipGrip™ gasket – a glue free gasket with superior alignment that ensures a perfect seal and trouble-free maintenance.
- Glued gasket – a two-component, oven-cured epoxy glue that keeps the gasket in place during any possible cleaning condition.
- CurveFlow™ distribution area – ensures full use of the heat transfer area and minimizes fouling.
Additionally, the pressure plate roller, the bearing boxes on tightening bolts, and the 5 point alignment system with reinforced hangers make opening and closing the heat exchanger quick and easy without the need for heavy tools or the risk of damaging the plates.
AlfaQ™ is quick and easy to modify if process parameters change. Our team’s expertise and the availability of parts bring you peace of mind.
Plate types for different needs
AlfaQ™ is available with two different plate configurations:
- Single plate with a chevron pattern design for parallel flow allowing for optimum thermal performance and pressure drop.
- Single plate with a chevron pattern design for diagonal flow through the heat exchanger when it is mounted horizontally and requires draining.
Peace of mind
Alfa Laval global service network is never far away.
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) Product Performance Certification Programme is a voluntary programme, administered and governed by AHRI, which ensures that various types of heating, ventilation, air conditioning, refrigeration, and water heating products perform according to manufacturers’ published claims.
Products that are certified through the AHRI Product Performance Certification Programme are continuously tested, at the direction of AHRI, by an independent third-party laboratory, contracted by AHRI, to determine the product’s ability to conform to one or more product rating standards or specifications.

Cómo funciona
Cómo funciona el intercambiador de calor de placas AlfaQ
La zona de transferencia de calor de un intercambiador de calor de placas con juntas está formada por una serie de placas onduladas, montadas entre el bastidor y las placas de presión, que mantienen la presión de diseño. El sellado entre las placas se realiza mediante juntas. Para obtener el máximo rendimiento térmico y permitir una aproximación muy estrecha de las temperaturas, los fluidos suelen circular en contracorriente a través del intercambiador de calor.
Alfa Laval AlfaQ™ está disponible con diversas profundidades de prensado y ángulos del patrón en forma de chevrón, así como con diversas formas de ondulación, todas ellas cuidadosamente diseñadas y seleccionadas para lograr un rendimiento óptimo. El CurveFlow™ y el área de distribución con patrón de chocolate son dos características de diseño disponibles que garantizan una distribución uniforme de los fluidos por toda la placa. El resultado es que se aprovecha al máximo toda la superficie de transferencia de calor y se evitan las zonas de estancamiento que pueden provocar incrustaciones.
La turbulencia del flujo intenso entre las placas da lugar a una mayor transferencia de calor; sin embargo, esto conlleva una caída de presión. Nuestros ingenieros de diseño térmico le ayudarán a diseñar y seleccionar el modelo y la configuración más adecuados para las necesidades de su aplicación, al tiempo que se garantiza el máximo rendimiento térmico y se minimiza la caída de presión.
