BTV Evaporator with Ventilation Train

Products > Blast Freezers and Blast Chillers

Manufactured with stainless steel tube and aluminum fin (Inox/Al). Compatible with all refrigerants (NH3, CO2, glycol, HFC, etc.). Modular design from 1 to 6 axial fans (Ø800, 900). Fin pitch: 7-10-12 mm.

BTV series evaporators are industrial units for floor installation. They are high efficiency and specially designed for flooded NH3 or CO2 systems (both pumped and gravity). Therefore, these exchangers are of robust construction, high performance and highly resistant to corrosion.

They are ideal for a wide range of industrial applications, such as static freezing tunnels and blast chillers. The BTV series comprises evaporators with a high degree of flexibility for application in customized solutions.
