Alfa Laval CB Brazed Plate Heat Exchanger
The Alfa Laval CB line comes with a range of brazed plate heat exchangers that features efficient heat transfer with extremely small footprint, making them ideal for demanding installations where space is at a premium. The CB range is used in HVAC heating/cooling, refrigeration, process heating/cooling, oil cooling. solar heating and many other applications.
Alfa Laval is the world’s leading manufacturer of brazed plate heat exchangers. This means that it has solid experience in designing units that are able to withstand high-pressure and high-temperature conditions, and in-coping effectively with the structural stresses that results from these. The units in the CB range are available in a variety of sizes and capacities, with differing plate patterns and connections for particular duties and performance specifications. Alfa Laval CB Brazed Plate Heat Exchanger units can be configured as a single-pass, dual-pass or multi-pass installations, according to project requirements.
All CB Brazed Plate Heat Exchanger units comply with the European Pressure Vessel Safety Directive, and can also be delivered according to other relevant standards and national codes, as required.
More capacity that you ever imagined
Alfa Laval CB is the largest brazed heat exchanger for single-phase duties. Thanks to larger flow rates, it can support larger applications that previous models with high thermal efficiency. The result is a significant increase in your volume – your profit margins. This model is ideal for a range of demanding duties including;
- Comfort heating and cooling applications, including district heating or direct cooling.
- Interchanger for heating and cooling.
- Lube and hydraulic oil cooling in engine applications with the special DOC410 version.
About CB
This thin, corrugated stainless steel plates used in the CB design are brazed together with copper. This forms a self-contained unit that can handle both high-pressures and high temperatures. And unlike traditional designs, the brazed plate heat exchanger consists solely of surfaces that actively contribute to heat transfer, resulting in significant increases in overall efficiency.
The CB range of brazed plate heat exchanger in both industrial, HVAC and refrigeration installations. The exceptional heat transfer efficiency makes all CB units very compact. As a result, they can tackle large-capacity duties even though there is only limited installation space available.
The brazed construction also does away with gaskets, making CB units ideal in applications where temperature and/or pressures are high. Examples include district heating and a wide range of heating, cooling and tap water solutions.
In Copper Brazed (CB) heat exchangers, the surfaces used to provide heat transfer from one medium to the other thin, corrugated stainless steel plates stacked on top of each other. The two media are sealed within the plate pack by a brazed copper seal around the edge of the plates. This results in a heat exchanger that – unlike traditional designs – consists solely of surfaces which actively contribute to heat transfer resulting in significant increases in overall efficiency.
The channels formed between the plates and corner ports are arranged so that the media flow through alternate channels – always in a counter-current flow pattern in order to achieve the most efficient heat transfer.
The contact points between the plates are also brazed, helping to withstand the effects of high pressures and high temperatures. Pressure peaks and rapid temperature cause substantial physical stresses within the materials, and Alfa Laval’s research has focused on the details of these phenomena in order to ensure the designs are extremely resilient and provide a long service life.
