Astoria 'Normal' Cartridge Type Heat Exchanger

Astoria Cartridge-Type Heat Exchanger (Older "Normal" Version)

This is the older-style "normal" cartridge heat exchanger used on Astoria CMA espresso machines, identifiable by its two fittings coming off the exchanger body at the same angle (not offset like the newer version). It transfers boiler heat into the brew water circuit for steady group temperature.

SPECIFICATIONS

• Dimensions: 52 x 165 mm
• Fitting: 3/8" male BSP
• Astoria CMA OEM part #: 4663002

COMPATIBILITY

• Fits: Astoria CMA machines using the older "normal" cartridge-style heat exchanger (fittings at a matching angle, not offset)
• Replaces: Astoria CMA 4663002

INSTALLATION

This is a boiler-plumbing component -- installation involves draining the boiler and working with threaded fittings, so we recommend a qualified espresso technician.

PRO TIPS

• Identify your version by fitting angle before ordering, this "normal" style has both fittings coming off the body at the same angle; if yours are offset, you have the newer version instead and this won't be a correct fit.
