Warning: with the "BRINE" KIT optional, it is mandatory to use antifreeze mixtures. The use of antifreeze mixtures may result in a decrease in the unit s performance. KIT LNO This optional is available as an accessory with the purpose of obtaining a reduction in noise emissions. This KIT includes: - Set of the working parameters. - A cap made with noise-absorbing material on each compressor. There are 3 different types of LNO KITS: KIT LNO 100% No air flow reduction. Noise reduction is obtained through a different working set of the microprocessor control and an acoustic insulation of the noise source. KIT LNO 85% Noise reduction is obtained through a different working set of the microprocessor control, an acoustic insulation of the noise source and a reduction of the condenser coil air flow at 85% of the nominal value. KIT LNO 70% Noise reduction is obtained through a different working set of the microprocessor control, an acoustic insulation of the noise source and a reduction of the condenser coil air flow at 70% of the nominal value. Consider that a condenser coil air flow reduction induces a minor cooling capacity of the machine and a major energy consumption of the compressor. Warning: To obtain the effective working conditions of cooling capacity and noise reduction for unit equipped with LNO KIT, please refer to the selection program. KIT XLS This optional accessory is available to obtain an extreme noise reduction on the machine. The versions equipped with XLS KIT have the following characteristics : - Set of the working parameters. - Machine frame and panels insulated with soundproofing material. - Soundproof cap on each compressor. - Compressor soundproof box. Consider that a condenser coil air flow reduction induces a minor cooling capacity of the machine and a major energy consumption of the compressor. Warning : To obtain the effective working conditions of cooling capacity and noise reduction for unit equipped with XLS KIT, please refer to the selection program. 19
Sound pressure (dba) Power input (%) EQSL HIGH PRESSURE EC AXIAL FANS The "EC" axial fans are equipped with a brushless type synchronous motor with integrated electronic commutated system. The motor rotation control is obtained with the EC system (Electronic Commutation) that manages the motor according to the 0-10V proportional signal coming from the microprocessor control. Characteristics of EC motors: - No electromagnetic noise. - Efficiency 83-86%. - Minimum power input. The following is a characteristics comparison between an "AC" asynchronous electric motor with phase-cut control (voltage controller) and "EC" brushless type synchronous motor. Electric motor revolutions (%RPM) Electric motor revolutions (RPM) Sound pressure level 1 meter far in free field conditions. Warning: The graphs are referred to working condition with null available static pressure (0 Pa). 20

PARTIAL HEAT RECOVERY SYSTEM **This optional accessory is not compatible with double cooling circuit units. The partial heat recovery exchanger is installed before the main condenser. The system is not regulated and the control is ON-OFF type. The heat recovery system s operation is subject to the supply and demand of cooling capacity. The system includes: - Copper brazed plate type heat exchanger with cover plates, plates and connections in AISI 316 stainless steel. - Anticondensate insulation made of polyurethane. - Upon request voltage free contact slot for partial heat recovery water pump activation. The water pump is not supplied. The heating capacity which is supplied depends on the kind of refrigerant gas which is used and working temperatures. The heat exchangers can produce hot water up to the maximum temperature of 70-75 C and according to the working conditions of the unit. PARTIAL HEAT RECOVERY HYDRAULIC CIRCUIT DIAGRAM 25
TOTAL HEAT RECOVERY SYSTEM The total heat recovery exchange is installed in parallel to the main condenser. The system is totally controlled by the microprocessor and the control is ON-OFF type. The heat recovery system s operation is subject to the supply demand of cooling capacity. For each refrigerant circuit the system includes: - Shell and tube condenser optimized for R134a refrigerant with shell, header, tube sheets made of carbon steel, tubes in Cu. - Anticondensate insulation made of polyurethane. - Antifreeze heater. - Water temperature probe on heat reclaim water inlet. - Diverter valve. - Non return valve. - Liquid receiver. - Safety valve. **Upon request: voltage free contact for total heat recovery water pump activation. The water pump is not supplied. The parallel connection of the hydraulic circuit is at Customer care and the water temperature probe is supplied not installed.
