DESCRIPTION
For compact heating and cooling systems, the Alfa Laval CB14 brazed plate heat exchanger is widely used in boilers, heat pumps, chillers, and domestic hot water applications. Its compact structure, fast heat transfer performance, and stable operation make it a common choice for both OEM equipment manufacturers and replacement projects.
The CB14 series includes multiple plate configurations such as CB14-10H, CB14-14H, CB14-20H, and CB14-30H, allowing engineers and buyers to select different heat transfer capacities based on flow rate and operating conditions. Compared with larger industrial plate heat exchangers, the CB14 is easier to install in wall-mounted boilers, compact mechanical rooms, and packaged HVAC systems where installation space is limited.

Alfa Laval CB10 vs. CB14 — Brazed PHE for Domestic Hot Water & Boiler Applications
Core Positioning
The CB10 is a general-purpose brazed plate heat exchanger designed for small-to-medium thermal duties across a range of applications including HVAC, refrigeration, oil cooling, and general industrial heat exchange. It is not specifically optimized for boiler or domestic hot water service.
The CB14, by contrast, is purpose-positioned for boiler hot water and domestic hot water heating duties. Its design priorities — rapid heat transfer, water hammer resistance, and reduced fouling tendency — make it one of the most commonly specified CB series models for boiler-side applications.
Construction & Materials
Both models share the same fundamental platform: 316L stainless steel plates with copper brazing, fully brazed with no gaskets, in a compact one-piece construction suitable for space-constrained installations. The key differences lie in capacity rating and application-specific optimization rather than base material or build method.
Technical Overview
While both units are built on the same brazed plate platform, their capacity profiles differ in a way that reflects their intended duties. The CB14 supports a nominal flow rate of approximately 8.2 m³/h — notably higher than the CB10’s 4.1 m³/h — despite accommodating a maximum of 14 plates compared to the CB10’s 20. The CB14 is rated to a maximum working temperature of 120°C, with a secondary-side design pressure of 10 barg and a documented fatigue test rating of 100,000 cycles at 0–15 bar, reflecting the mechanical demands typical of boiler and hot water circuits. The CB10’s pressure and temperature limits vary by configuration and are best confirmed against specific model and plate count selections.
Application Fit
Specify CB10 for:
- HVAC heating and cooling systems
- Heat pump unit heat exchange duties
- Industrial oil cooling and process cooling
- Compact installations with stable, moderate thermal loads
Specify CB14 for:
- Residential and commercial boiler hot water systems
- Domestic hot water (sanitary water) heating
- Centralized heating in apartments, residential buildings, and commercial properties
- Applications with specific water hammer or fouling control requirements
Selection Guidance
Where the primary requirement is boiler integration or domestic hot water heating, the CB14 is the more targeted specification — its water hammer-resistant construction and fouling-control design are directly optimized for that duty. For HVAC, heat pump, or general industrial cooling applications with clean media and stable operating conditions, the CB10 delivers adequate thermal performance within a compact footprint. Neither model is recommended where process fluids carry significant particulate content, where regular disassembly and cleaning is required, or where flow demands consistently approach or exceed the unit’s rated capacity.
