Technical features
Screw compressors:
• Semi-hermetic screw compressors, BITZER;
• electronic protection;
• integrated oil separator;
• differential pressure lubrication system;
• oil filter;
• oil level safety device;
• crankcase heater;
• refrigerant R134a;
• high and low pressure gauges and pressure switches;
• continuous proportional control (25/100%).
Condenser
• Higher efficiency and performances
• mechanically expanded copper tubes in collar, spaced by alumi-nium fins with very low internal volume, "V-shape" arrangement;
• special integrated sub-cooling circuit.
Axial fans
• TC: fans with phase cut speed control
• TRIAC speed regulation;
• fan speed continuous adjustment with consequent condenser cooling air flow regulation;
• correct pressure in the refrigerant circuit guaranteed even at low winter temperatures.
• EC: brushless variable speed fans:
• high efficiency, improved reliability and durability;
• integrated electronics;
• 100% adjustable speed;
• consumption reduced by more than 30%;
• low noise emissions (less than 57dB(A));
• complies with the strictest EMC regulations.
• EH: high head EC fans
• suitable for ducting on indoor installations (heat recovery) ;
• for ambient temperatures greater than –15 °C.
Shell and tube evaporator
• Optimised for use with R134a refrigerant;
• copper tubes with high exchange surface area
• thermal insulation;
• water differential pressure switch;
• water circuit drain;
• air vent valves and hydraulic connections conveyed to the outside with VICTAULIC elastic joint or flanged adapter.
Systems
Modularity
Allows to easily build large systems, rating cooling capaci-ties from 100 to 3.500 kW.
Configurations
There are two main system configurations:
• Modular Central Cooling Systems: units connected in parallel designed to add capacity as the thermal loads increase;
• MultiStage Cascade Cooling Systems: units connected in series designed for cascade cooling.
Heat pump
For both system configurations a Heat-Pump optional feature is available.
Accessories
In both parallel and cascade configurations, are inte-grated with a full variety of accessories, such as modular recirculating and process pumping stations, stainless steel tanks, filtration systems and a remote control sys-tem that automatically manages capacity control, energy consumption optimization, working hour equalization, alarms and all operating parameters.
