GNH SERIES
Nominal Capacities between 35 and 168 KW
Nominal Capacities between 35 and 168 KW
Large industrial cubic evaporators for all kind of applications with three phase fan motor of diameter 630 and 800mm for refrigerant ammonia pumped, gravity or direct expansion DX system.
Manufactured with stainless steel tube with options AISI-304L and AISI-316L expanded over aluminium fins.
These units can also work with other refrigerants (R-404A, water-glycol, etc.) as an alternative to the standard copper tube models GR when the ambient condition inside the cold room is harmful for copper.
