Description
2.2.1
Introduction
The
CRT
roof top series are designed for the conditioning of the industrial environment
exposed to high temperature. Their main purpose is to guarantee a comfortable and
steady temperature to the persons or equipment working in the production process.
The
CRT
AC differs due to its technical features which allow its utilization in particular
ambients with high temperatures and weather exposition. Tanks to low maintenance
needing, to the easy access to internal components and to high reliability, is suitable to
be easyly installed in several applications.
2.2.2
Components description
Package unit air conditioner, designed for roof top installation on cabinet,
power panels and containers.
The interfacing to the enclosure if made through rigid air ducts, to
guarantee the maximum sealing, are equipped by flange and relative
gaskets.
The load bearing frame is made of steel sheet, protected by a special epoxy
based coating. Removable panel allow the service access to internal side.
On request, available even in stainless steel or with different surface
treatment.
Hermetic alternative compressor, mounted on anti-vibrating supports.
Specific to operate on high compression rate, with autonomous lubrication
and built-in thermal protection.
The axial fan blades are directly coupled to the motor shaft, are dynamically
balanced. The rotor rotates on ball-bearing. Against hand contact, are
provided protection metal grids.
The air exchanger are finned pack type, copper tube/manifold and
aluminium fins with surface “hydrophilic” treatment against corrosion and
condensate cohesion.
Cooling circuit completely made of copper tubes, tube/tube junction
brazed with fine alloys. Complete of expansion device, mechanical filter,
safety devices against overpressure, fan speed regulation and anti-freeze
sensor.
Factory wired electric panel, complete of microprocessor based
thermoregulator, in according to rules and regulations in force.
Air filter on suction sections of recirculation circuit.
