TECHNICAL CHARACTERISTICS

ZETA ECHOS FC Air-cooled water chiller with free-cooling, hermetic scroll compressors and plate evaporators. The features of the standard units are as follows: UNIT FRAME Self-supporting frame with removable panels clad with expanded polyurethane sound-absorbing matting, made of galvanised sheet steel with 180°C baked-on polyester powder coating (Colour RAL 5014) to provide a durable weatherproof finish. Threaded fasteners in stainless steel. COMPRESSORS Hermetic type orbital scroll compressors connected in parallel, equipped with an oil level sight glass, thermal protection by means of an internal Klixon cut-out and oil equalisation line. The compressors, which are housed in a sound insulated compartment and separated from the air flow, are accessible by removing specific panels that allow maintenance work to be carried out while the system is running. CONDENSERS Composed of a high efficiency coil with staggered pattern rows of copper tubes and aluminium fins. The finned core is protected by a grille with metal mesh filter supplied as standard. FREE COOLING Made up from an interpenetrating coil with rows with copper pipes and high-efficiency aluminium fins. The finned core is protected by a grille with metal mesh filter supplied as standard. A unique ventilating section cools the condensing coil and the free-cooling coil, which are positioned in parallel on opposite sides of the unit. The air flow is managed automatically by a microprocessor that controls the opening of motorised shutters positioned facing the coils and regulates the rotation speed of the fans. When the conditions make it suitable, the free-cooler shutter is opened, the fans are made to turn at maximum speed and condensation is controlled by modulating the opening of the condenser shutter. Otherwise, the free-cooler shutter remains closed, that of the condenser completely open and condensation is controlled by regulating the rotation speed of the fans. FANS Axial fans with rev. regulator for slave application, designed to optimise efficiency and reduce noise emissions, directly coupled to a 6-pole motor with internal Klixon overload protection. Motor protection rating is IP 54. The fan is equipped with a safety grille in compliance with UNI EN 294. EVAPORATOR Stainless steel 316 AISI brazed plate exchanger, thermally insulated by means of a jacket in closed cell expanded material. Each evaporator is equipped with a freeze protection temperature probe and each unit is equipped with a mechanical flow switch as part of the standard outfit. The use of plate type heat exchangers makes for: · Improved COP/EER; · Reduced refrigerant charge in the circuit;

· Reduced unit weight and dimensions; · Easier maintenance. REFRIGERANT CIRCUIT The refrigerant circuit includes: liquid line shut-off valve, charge connection, liquid line sight glass, filter dryer, thermostatic expansion valve with external pressure equalisation, high and low pressure switches, and relief valve. The high and low pressure values and relative condensing and evaporating temperature values are detected by means of pressure transducers which enable the relative data to be read on the controller display. Note that the high pressure side is anyway equipped with high pressure switches and relief valves.

VERSIONS

HYDRAULIC MODULE OPTIONS ZETA ECHOS FC /ST 2PS: Unit with storage tank and pumps In addition to the components featured on ZETA ECHOS FC, this model includes: · insulated storage tank; · two water pumps, one of which in stand-by with automatic changeover in case of faults; · expansion vessel; · check valves; · gate valves. Version ST is available in a further four configurations: ST 1PS: with one pump and tank; ST 1P: with one pump and without tank; ST 2P: with 2 pumps without tank; ST S: with tank without pumps. ACCESSORY VERSIONS ZETA ECHOS FC /LN: Low noise unit. As well as the components of the basic version, the unit also envisions the compressors compartment which is completely noise insulated using sound-absorbant and sound-proof materials. ZETA ECHOS FC /NG: No glycol unit As well as the components of the basic version, the unit, envisions a further water-water heat exchanger that allows to confine the mixture of water and glycol in a closed circuit inside the machine. Once the mixture is cooled, it is sent to the above-mentioned heat exchanger where it absorbs heat from the water coming from the utilities circuit.

INSTALLATIONS RECOMMENDATIONS
