Alfa Laval CB200 Brazed PHE for hvac
The CB200 is a fully brazed plate heat exchanger designed for rapid, efficient thermal transfer between two fluid streams. Its gasket-free brazed construction makes it well suited to refrigeration, heating, heat recovery, and heat pump circuits — particularly in building systems where space and uptime are critical.
With no gaskets to maintain, a compact footprint, and a flexible range of plate and connection configurations, the CB200 delivers high thermal performance while keeping installation and operational costs low.
Typical HVAC Applications
Chiller Evaporator / Condenser
The CB200 transfers heat between refrigerant and water or glycol solution, supporting efficient cooling and heat rejection within chiller circuits.
Heat Pump Systems
Used as the heat exchange component on the heat pump side, it maintains high thermal efficiency across both heating and cooling operating modes.
Primary / Secondary Circuit Isolation
The CB200 decouples the primary source loop from the building secondary circuit, simplifying water treatment and protecting downstream equipment from pressure variations.
Domestic Hot Water
Transfers heat to domestic hot water or process water circuits through indirect exchange — a common solution in hotels, hospitals, and office buildings.
Heat Recovery
Recovers useful heat from exhaust air, cooling loops, or waste heat streams for fresh-air pre-heating or supplemental space heating, reducing overall system energy consumption.
District Cooling / Heating
Works alongside air handling units and fan coil unit water systems to deliver precise zone-level temperature control in larger building or campus environments.
Why CB200 for HVAC
Structural Reliability
The fully brazed construction eliminates gasket degradation caused by pressure and temperature cycling — a key advantage over gasketed plate heat exchangers in long-running HVAC systems. With fewer serviceable parts, maintenance burden and downtime are significantly reduced.
High Thermal Density
Large plate surface area combined with compact, optimized flow channels delivers high thermal capacity within a small physical envelope. This is particularly valuable in plant rooms where available space is limited.
Engineering Flexibility
The CB200 is available in a wide range of plate counts, channel configurations, and connection orientations. Sizing is determined by actual project parameters — flow rate, allowable pressure drop, design temperature difference, and fluid type — allowing engineers to select the most efficient configuration for each application.
Selection Checklist
When specifying the CB200, confirm the following parameters for both fluid sides:
- Design flow rate and operating range
- Inlet and outlet temperatures, and design temperature difference (ΔT)
- Allowable pressure drop on each side
- Fluid type and concentration (water, glycol solution, or refrigerant)
- Maximum working pressure and temperature
- Installation envelope and connection orientation requirements
