'Pack' - High performance low height louvre fin core of packed construction.

Application - stationary and vehicle duties where performance and cost are supreme importance.

'P' - Flat fin and tube (G.O.T) construction, with high density, large through-area tubes on continuous stagger pitch giving high thermal performance with low fouling characteristics both internal and external.

Application - Stationary and vehicle duties in dusty conditions and when extended life is required.

'PT' - The 'P' type core with full solder coated fins giving enhanced corrosion protection.

Application - Coastal, off sure and other corrosive environments.

'Wire wound tube' - Welded circular tube with internal and external helically wound wire secondary surface with high pressure and thermal performance capability.

Application - High pressure oil and gas.

'CAP' - Flat fin and tube (G.O.T) construction core with low fin density incorporating high temperature solder tube to tube plate joint.

Application - Engine charge air cooling.

'PME' - Multi-entry louvred fin and tube (G.O.T) construction offering many of the benefits of the 'P' type core with a reduced material content.

Application - Stationary and vehicle duties with extended life requirements.
