ROOFTOP TYPE UNITS. AIR COOLED CONDENSER. SERIES RXCZ
AIR CONDITIONING
DESCRIPTION General The RXCZ series equipment consists of packaged Rooftop cooling only units, air condenser which are specially recommended for installation on roofs, terraces, and outdoor spaces. The treated air from the interior area may be conducted by the equipment base (downflow return and supply) or by the sides (lateral return and discharge).There are also other variations to suit most site requirements. The units are supplied fully complete with a suitable refrigerant charge for correct operation. This equipment has been designed so that there is no possibility of water entering the air ducts, whether this is condensation, or rain water. The base, which is constructed from sheet profiles, provides structural rigidity for handling or transport without any risk to interior components. Cabinet The structure of these units is completely weatherproof. The base is constructed from very strong steel sheet. The rest of the structure is steel sheet galvanized, that is covered with polyester paint, which is applied in powder form and oven-polymerised at 190 °C, which provides excellent coverage at edges and corners, together with optimum corrosion resistance. The s are internally lined with heat and acoustic insulation. The access s are fitted with quick-action (1/4 turn) catches. The completed unit is in colour RAL 1013. Cooling circuit This includes the following elements: - One or two fully independent circuits. - Indoor and ourdoor coils of copper piping and aluminium fins. - ACR copper refrigerant line. - In-line drying filters. - Schrader valves for high and low pressure service connections. - Expansion system. Compressors One or two 407C hermetic compressors. Models 1501, 3002, 4002 and 4502 are fitted with scroll compressors, which are specially designed for operation under extreme conditions, and include an oil pump. Each compressor include internal thermal protection. A crankase heater is included to provide protection against refrigerant liquid slugging during start-up. Outdoor and indoor coils The coils are constructed of 3/8” non-welded copper piping, which are expanded in aluminium fins. Fans Those of the indoor section are of the double-suction centrifugal type, with static pressure available for application to ducting. They are driven by adjustable belt-pulley transmissions. These fans are low-noise and include pre-lubricated bearings, which are both statically and dynamically balanced.
Those of the outdoor section are of the axial type and are totally sealed, ready for outside weather conditions, with permanent lubrication. They consist of aluminium blades which have been designed to produce reduced noise levels that are inserted in the exterior rotor of a highefficiency motor having IP-54 protection and class F insulation. They are equipped with internal thermal sensors, together with exterior safety grilles. The exterior area air flow is independent for each cooling circuit. Expansion devices The interior section includes thermostatic expansion valves, which are completed with refrigerant distributors. Air filter Polyurethane foam, which is washable and reusable, with a special lattice providing excellent filtration efficiency. Fire classified M1. Operation and control equipment - Controller. - Main switch. - 230/24V transformer and relay system for or coil energising. - ors for operating compressors and fan motors. - Thermal protection for indoor section motors. - H.

AIR CONDITIONING
ACCESSORIES “FREE-COOLING” ECONOMIZER The “free-cooling” economizer takes advantage of the temperature and humidity conditions (enthalpic comparison) or only temperature (thermal comparison) of the outside air with respect to the return air and uses it to condition the areas requiring cooling in function of the value set by the system control, making whatever mixes are necessary and may even shutdown the compressors, with the corresponding energy savings. The system consists of an electronic control centre which receives information from the exterior and return air sensors by means of a continuous comparison (enthalpic or thermal), and feeding the actuators for the corresponding gates, producing a 100% proportional regulation.
OPTION A (basic) - Fresh air damper. - Mixing damper.
OPTION B (complete) - Fresh air damper. - Mixing damper. - Return fan. - Exhaust damper.

ROOFTOP TYPE UNITS. AIR COOLED CONDENSER. SERIES RXCZ
AIR CONDITIONING
DESCRIPTION General The RXCZ series equipment consists of packaged Rooftop cooling only units, air condenser which are specially recommended for installation on roofs, terraces, and outdoor spaces. The treated air from the interior area may be conducted by the equipment base (downflow return and supply) or by the sides (lateral return and discharge).There are also other variations to suit most site requirements. The units are supplied fully complete with a suitable refrigerant charge for correct operation. This equipment has been designed so that there is no possibility of water entering the air ducts, whether this is condensation, or rain water. The base, which is constructed from sheet profiles, provides structural rigidity for handling or transport without any risk to interior components. Cabinet The structure of these units is completely weatherproof. The base is constructed from very strong steel sheet. The rest of the structure is steel sheet galvanized, that is covered with polyester paint, which is applied in powder form and oven-polymerised at 190 °C, which provides excellent coverage at edges and corners, together with optimum corrosion resistance. The s are internally lined with heat and acoustic insulation. The access s are fitted with quick-action (1/4 turn) catches. The completed unit is in colour RAL 1013. Cooling circuit This includes the following elements: - One or two fully independent circuits. - Indoor and ourdoor coils of copper piping and aluminium fins. - ACR copper refrigerant line. - In-line drying filters. - Schrader valves for high and low pressure service connections. - Expansion system. Compressors One or two 407C hermetic compressors. Models 1501, 3002, 4002 and 4502 are fitted with scroll compressors, which are specially designed for operation under extreme conditions, and include an oil pump. Each compressor include internal thermal protection. A crankase heater is included to provide protection against refrigerant liquid slugging during start-up. Outdoor and indoor coils The coils are constructed of 3/8” non-welded copper piping, which are expanded in aluminium fins. Fans Those of the indoor section are of the double-suction centrifugal type, with static pressure available for application to ducting. They are driven by adjustable belt-pulley transmissions. These fans are low-noise and include pre-lubricated bearings, which are both statically and dynamically balanced.
Those of the outdoor section are of the axial type and are totally sealed, ready for outside weather conditions, with permanent lubrication. They consist of aluminium blades which have been designed to produce reduced noise levels that are inserted in the exterior rotor of a highefficiency motor having IP-54 protection and class F insulation. They are equipped with internal thermal sensors, together with exterior safety grilles. The exterior area air flow is independent for each cooling circuit. Expansion devices The interior section includes thermostatic expansion valves, which are completed with refrigerant distributors. Air filter Polyurethane foam, which is washable and reusable, with a special lattice providing excellent filtration efficiency. Fire classified M1. Operation and control equipment - Controller. - Main switch. - 230/24V transformer and relay system for or coil energising. - ors for operating compressors and fan motors. - Thermal protection for indoor section motors. - H.

AIR CONDITIONING
ACCESSORIES “FREE-COOLING” ECONOMIZER The “free-cooling” economizer takes advantage of the temperature and humidity conditions (enthalpic comparison) or only temperature (thermal comparison) of the outside air with respect to the return air and uses it to condition the areas requiring cooling in function of the value set by the system control, making whatever mixes are necessary and may even shutdown the compressors, with the corresponding energy savings. The system consists of an electronic control centre which receives information from the exterior and return air sensors by means of a continuous comparison (enthalpic or thermal), and feeding the actuators for the corresponding gates, producing a 100% proportional regulation.
OPTION A (basic) - Fresh air damper. - Mixing damper.
OPTION B (complete) - Fresh air damper. - Mixing damper. - Return fan. - Exhaust damper.

“ARIA” ELECTRONIC CONTROL
(For RXCZ without economiser)
“Aria” is a microprocessor-controlled regulator consisting of two integrated elements: a TERMINAL for location in the controlled environment, together with a POWER CARD which is housed in the machine’s electrical board. The connection between the terminal and the power board requires only a pair of wires. Power Board Terminal
Maximum: 150 metres
screen display
The terminal’s side keys provide access to the various functions: MODE: Selects Cool, Heat, Auto, Fan or Off. FAN: Determines operation of Fan. SET: Adjusts set points: Comfort, Absence, Night-time. CLOCK: Time clock and phases. With clock (consult availability). HOLD: Various function and parameter output management. RESUME: Reset alarms, programming phase output. Front keys: Permit set point modification.
The LCD shows environmental temperature, the COOL/HEAT function, fan operating mode, set point category: presence, absence, night-time and comfort etc. Characteristics - Liquid crystal Display (LCD). - Option: remote temperature sensor. - Option: Clock for timer programming. - Green multiple information LED (on power card). Applications 1. STAND-ALONE type: one controller per machine. 2. LAN (Local Area Network): permits control of up to 30 units, each unit with its associated terminal with LAN output, centralising all information and control in a pCO terminal (consult).

THERMOSTAT
(Alternative to "ARIA" controler)
Microprocessor-controlled 24 Vac electronic thermostat, which is internally configurable and connected to the machine by cable to regulate the equipment functions, one or two stage cooling, together with one or two stage heating. The environmental thermostat permits individual machine control and automatic start-up/shutdown, cooling and heating (electrical heating elements or hot water battery), continuous or automatic ventilation (with the corresponding function). The liquid crystal screen displays the environmental temperature, set point, operating mode and ventilation mode etc, together with their associated icons.

External sensor (consult)
(only with external sensor as an option). The termostat will accept wall, duct or external sensors. The application of a duct sensor requires the wall sensor. Note: Up to six sensors can be used on large premises. The system calculates the arithmetic average of the temperatures detected by each one.
PCO TERMINAL For “Rooftop” unit control when this incorporates “free-cooling”. The pCO has several control levels available and accessible using the corresponding s. It is employed to configure the equipment at the factory and for -modification of the basic operating parameters. The LCD shows the COOL/HEAT operation, environmental temperature, the time (with clock card) and alarms etc.
