DESCRIPTION
The ACHA-ACHBA series are air conditioner units of horizontal construction, suitable to be adapted to an air duct distribution system on both indoor and outdoor sides.

CABINET
Cabinet is made of galvanized steel sheet, finished with polyester powder, electrostatically applied and oven-polymerized of optimum
resistance to corrosion. The assembly is internally lined with thermoacoustic insulation.

COMPRESSORS
Compressors are equipped with internal thermal protection -any other additional protection is not needed-, and they incorporate internal shock-absorbing systems mounted on the base with antivibration supports. Lubricant oil -resistant to high temperatures- and crankcase heater are included. Models 201 and 251 incorporate 230V single-phase compressors, 50Hz. Rest of models are equipped with 400V three-phase compressors, 50Hz, Scroll type from model 371 onwards.

HEAT EXCHANGERS
Coils are made of aluminium fins and 3/8" copper tubing, mechanically expanded, of high exchanging efficiency.

EXPANSION DEVICE
Models 201 - 501: restrictors on both indoor and outdoor sections.
Models 701 - 1201: restrictors on outdoor section and expansion valves on indoor section

AIR FILTERS
Washable polyurethane foam of 10mm thickness, S-20 highefficiency filtering.

FANS
Centrifugal fans on both indoor and outdoor section suitable for duct application.
Indoor section: Models 201 up to 401 driven by fans with incorporated single-phase motor and permanent capacitor. Models 501 to 1001, fans are driven by three-phase motors, transmission is made through pulleys and belt.
Outdoor section: Models 201 up to 721 driven by fans with incorporated single-phase motor and permanent capacitor. Models 751 to 1201 fans are driven by three-phase motors, transmission is made through pulleys and belt.
Fans are of reduced sound power level, incorporate pre-lubricated bearings and are static and dynamically balanced.

REFRIGERANT CIRCUIT
Made of high grade refrigerant copper tubing, clean and dehydrated, incorporating filter dryer and Schrader Valves to allow easy access during verification and charge. The suction accumulator ensures the return of oil and protects the compressor from liquid flooding.
Reversing valves to inverse the cycle and one-way valves. The welds between the different elements are executed with copper-silver alloy.

OPERATE AND CONTROL EQUIPMENT
Each unit is supplied with the following protection devices:
• Room thermostat 24V ac.
• Transformer with 24V outlet for relay operating system.
• Contactors for compressor, fan motor, etc.
• Overloads for three phase fan motors.
• High pressure pressostat (manual reset) and low pressure pressostat (automatic reset).
• Reversing valve, solenoid operated 230V.
• Defrost system based on periods of time and outdoor coil temperature.
