6 TECHNICAL CHARACTERISTICS TETRIS Water chiller Compact-size air-cooled water chiller with hermetic scroll compressors, axial fans and plate evaporators. Refrigerant R410A. UNIT FRAME Modular, galvanized sheet structure with self-supporting frame, with bakedon polyester-powder coating (colour RAL 5014) providing excellent weather resistance. Stainless-steel threaded fasteners. COMPRESSORS Hermetic orbiting scroll compressors, connected in parallel, equipped with oil sight glass, internal Klixon thermal circuit-breaker, contactors and oil-equalizing line. CONDENSERS Finned-coil heat exchanger with copper tubes and aluminium fins. The coils V-shaped arrangement allows smaller unit size while increasing the air suction area and leaving more room for the components of the refrigerant circuit and hydraulic circuit, if present. The refrigerant circuits condensing sections work independently. ELECTRIC FANS Axial fans with sickle-shaped blades and manifold, designed to improve performance and reduce noise, directly coupled to 6-pole three-phase electric motor, with internal Klixon thermal circuit-breaker. Motor protection rating IP 54. The fan comes supplied with a safety grid. EVAPORATOR AISI 316 stainless-steel braze-welded plate evaporator, housed inside a closedcell insulating casing. Models with 2 refrigerant circuits are equipped with a 2-circuit exchanger having a single hydraulic coupling, while models with 4 refrigerant circuits are equipped with a double 2-circuit exchanger and hydraulic couplings with manifolds. Using 2-circuit plate-type heat exchangers presents the following advantages: Higher COP/EER values; Smaller amount of refrigerant in the circuit; Smaller unit size and weight; Easier maintenance; Each evaporator is equipped with a temperature probe for antifreeze protection. The hydraulic manifold is provided with a flow switch and a probe for measuring the temperature of the return water flow. REFRIGERANT CIRCUIT Includes: liquid line cut-off valve, 5/16 charge couplings, liquid-level sight glass, replaceable solid-core filter-dryer, electronic expansion valve. Models with 2 compressors (from 10.2 to 16.2) are equipped with high and lowpressure gauges and safety valves. Models with 3 to 12 compressors (from 20.3 to 93.12) are equipped with pressure transducers for checking high and low pressure values and the relative evaporation and condensation temperatures, high-pressure gauges and safety valves. The electronic expansion valve acts as a solenoid valve on the liquid line: it closes when the circuit is stopped, cutting off the liquid s flow. On request, the electronic valve can be equipped with a buffer battery so that it closes even during power failures. 6 Technical Catalogue Tetris

8 VERSIONS Refer to the configurations table to check for possible incompatibility between options. TETRIS /HP: Reversible heat pump In addition to the features of the Tetris version, this version includes: 4-way switch-over valve; liquid storage tank; microprocessor enabling for summer/winter switching and automatic defrosting, with patented Blue Box logic to optimize defrosting time independently on each circuit. HYDRAULIC MODULE OPTIONS TETRIS /ST: Unit with tank e pumps In addition to the features of the Tetris version, this unit can be supplied with an insulated inertial storage tank and circulation pumps. The following configurations are available: ST 1PS: with 1 pump and tank; ST 1P: with 1 pump without tank; ST 2PS: with 2 pumps and tank (from size 10.2 to 24.3); ST 2P: with 2 pumps without tank (from size 10.2 to 24.3); ST 3PS: with 3 pumps and tank (from size 27.4 to 93.12); ST 3P: with 3 pumps without tank (from size 27.4 to 93.12); On the version with 2 circulation pumps (one on standby for the other, both sized for 100% of total flow), switching from one pump to the other is automatic in case of breakdowns or can be set by time. On the version with 3 pumps (each sized for 33% of total flow) all 3 pumps work at the same time; if one pump breaks down, up to 78% of the cooling capacity can still be provided. The following accessories are also provided: expansion tank, check valves (except for versions 1P and 1PS) and gate valve at suction intake (only on versions with tank). TETRIS /DS: Unit with desuperheaters In addition to the features of the Tetris version, this unit includes a recovery condenser on each refrigerant circuit for recovering 20% of the heat of condensation, installed in series with the condensing coil. The condenser is a plate-type condenser. For best performance, this accessory should be used together with a fan speed control. This version is also available in the HP configuration. In this case, the installation must include a cut-off on the recovery water circuit during HP operation, as indicated in the manual. TETRIS /LN: Low-noise unit In addition to having the features of the Tetris version, on this unit the compressor compartment is completely soundproofed with sound-absorbing material and the insertion of sounddeadening material. TETRIS /SLN: Super low-noise unit In addition to having the components of the Tetris/LN version, on this unit the fan speed is reduced by an automatic fan speed control, when allowed by local conditions. ACCESSORY VERSIONS TETRIS /DC: Unit with recovery condenser In addition to the features of the Tetris version, this unit includes a recovery condenser on each refrigerant circuit for recovering 100% of the heat of condensation from the plates for hot water, and a liquid collector. The control automatically starts heat recovery depending on the water temperature, and stops recovery for safety reasons when the pressure is too high. For best performance, this accessory should be used together with a fan speed control. 8 Technical Catalogue Tetris
