Industrial Dual Discharge Evaporators StStAl_senzal

Industrial Dual Discharge Evaporators (StSt/Al)

ED dual discharge air coolers distribute the air to ensure homogeneous cooling throughout the chamber without creating drafts. The ED series is designed for installation in chambers or corridors (long rooms), where uniform air distribution is essential

Manufactured with stainless steel tubes and aluminium fins (StSt/Al). Compatible with all refrigerants (NH₃, CO₂, glycol, HFC, etc.). Modular design from 1 to 5 axial fans (Ø350, 450, 500, 560, 630). Fin pitch: 4-4,5-5-6-7-8-9-10-11-12 mm.

ED series evaporators are dual discharge industrial evaporators, specially designed for flooded NH₃ systems (both pumped and gravity). The robust construction of our ED evaporators , offer high performance and high resistance to corrosion.

Directly applicable for frozen chambers, refrigerated and preservation chambers in the fruit and vegetable, fish and meat industries, and distribution centers in the food industry. Range of standard evaporators with a high degree of flexibility for application in customized solutions.
