Description

CU_ALX series are internal packaged-type, ideal for the cooling of applications electrical boards and similar items for indoor applications. They are designed to be positioned on the external wall of the cabinet.

These units work according to the cooling cycle direct expansion, so heat transfer is performed by a fluid (refrigerant) that acquires sensible heat through the evaporator coil and removes it through the condenser coil, which are parts of the sealed refrigerant circuit.

The fluid is driven by a electric motor-compressor unit. The evaporator coil is directly facing the cabinet internal, while the condenser coil faces the external room. The STANDARD basic version is equipped with analogic temperature regulation with range 25°C/35°C, ON-OFF switch and a protection fuse.

On request the series can be equipped with electronic temperature controller (CU_ALXC).

Description

CU030ORZ ACU is packaged type, designed and manufactured to cool electrical enclosures and similar items. Very compact and light, it is designed to be positioned horizontally on the external walls of the enclosure; such a shape makes it suitable for being installed also on doors and hinged panels.

The ACU is purposely designed to allow several types of installation:

EXTERNAL MOUNTING: the ACU is mounted externally on the wall of the electrical enclosure. The advantage of this configuration is that you have no room lost in the enclosure’s internal.

INTERNAL MOUNTING: the ACU is mounted internally on the wall of the enclosure. The advantage of this configuration is that the room required externally is reduced to the dimensions of the plastic grille.

EMBEDDED MOUNTING: this mounting configuration is ideal in those situations where the solution is between the two above. For this mounting configuration a kit with frames, screws, washers and plugs is available upon order.

Electrical connection with IEC cable connector and IEC panel-mounted plug, with switch and fuse protection.

CU030ORZ features forced-air-circulation evaporator and condenser, with radial fans, to improve performances and to provide an even temperature’s distribution in the enclosure’s internal.

CU_ROOF

Description

CU_ROOF series ACUs are packaged-type, designed and manufactured purposely to cool electrical enclosures and similar items.
Built to be installed on roof-top of electrical enclosures, their shape makes them suitable for many other applications; the units are also equipped with very ef f icient condensate draining systems.

They work according to the principle of the reversed Rankine cycle, so heat transfer is performed by a fluid (refrigerant) that acquires sensible heat through the evaporator coil and removes it through the condenser coil, which are parts of the sealed refrigerant circuit.
The fluid is driven by a electric motor-compressor unit.
The evaporator coil is directly facing the enclosure internal, while the condenser coil faces the external room.

The CU_ROOF Series ACUs are small sized and take no room sideways the enclosure.
