Chiller VLC 524 to 1204 Air Cooled Condensing Units Engineering Data Manual 154 to 347 kW
Outstanding Strength Points Units with R410A refrigerant (it will be the real replacement of R22). As near azeotropic mixture it behaves like a homogeneous substance (reduced service problems in case of leakage or re-charge) with negligible temperature glide. Refrigerant with superior thermo-dynamical proprieties compared to R22 and R407C, it allows to have more efficiency or compact and lighter systems and larger operating limits.
Specifications (continued) Fan speed control The speed of fans is controlled in order to operate at a low ambient temperature. On units with standard axial fans, the fan speed control, supplied as standard, is of a temperature actuated step type (for BLN and LN versions) and of a pressure actuated stepless type with an electronic controller (for ELN version). The pressure actuated stepless type fan speed controller can be supplied as optional on BLN and LN versions.
