Alfa Laval
CB Brazed Plate Heat Exchanger
The Alfa Laval CB is a copper-brazed plate heat exchanger that delivers efficient heat transfer in a small footprint. It is a true all-rounder, serving HVAC heating and cooling, refrigeration, oil cooling and general industrial heating and cooling duties.
Product Benefits
- Efficiency without bulk: The brazed, gasket-free construction delivers high thermal efficiency without the size, gaskets or maintenance overhead of larger exchanger types.
- Several pressure ratings: Different pressure ratings are available within the range, so the same compact format can be specified for both moderate and more demanding systems.
- Even refrigerant spread: For evaporator duty the unit can be supplied with a refrigerant distribution system that keeps refrigerant spread evenly across the plate pack for optimal performance.
- Full-vacuum tolerant: The design also tolerates full-vacuum conditions.
Where It's Used
- HVAC circuits: Typical services include building heating and cooling circuits.
- Refrigeration and oil cooling: The CB also serves refrigeration systems and oil cooling duties.
- Industrial process duty: It handles process heating and cooling across general manufacturing.
- A familiar sight: That versatility makes the CB a common sight in buildings, refrigeration plants and factories alike, wherever compact and efficient heat transfer is needed.
Good to Know
- Materials: Stainless steel plates are joined by copper brazing between stainless cover plates.
- Connection options: Connections are offered as external thread, internal thread, soldering or welding.
- Approvals: Units are PED and UL approved.
- Clean fluids, not cleaning: Because the unit is permanently sealed, plan for clean, filtered fluids rather than mechanical cleaning.
- Specify by design conditions: Match the pressure-rating variant to your system's design conditions, and consider the distribution system option if the unit will run as an evaporator.
