Main features Industrial unit coolers for ammonia operation LSA-CSA

Heat Exchanger

CHS – Compact Hitec Surface

TURBOFIN® 3 heat exchanger with stainless steel tubes and staggered rows, suitable for both positive and negative temperature applications for the conservation of products with low humidity content, or packed products.


LHS – Large Hitec Surface

TURBOFIN® 4 heat exchanger with stainless steel tubes and in-line rows, featuring a high ratio between the secondary fin surface and the primary tube surface, suitable for conservation cold rooms for products with high humidity content, and for freezing.


Fin spacing and best use

Range 4 – 4.5 mm: conservation at positive temperature

Range 6 – 6.0 mm: conservation at positive temperature

Range 7 – 7.5 mm: conservation at negative temperature

Range 10 – 10 mm: freezing and conservation at negative temperature

Range 12 – 12 mm: freezing
