The diagrams published in this catalogue are to be considered as a general diagram for the full range of compressors. Check the diagram of every single compressor model on the Frascold Selection Software program. Safety Frascold compressors are constructed according to European and American (UL) safety standards. They may only be used if installed within systems complying with the operating instructions and conforming to the regulations in force. The relevant standards are listed in the Manufacturer s Declaration, available on request or on the website in the certification section. The compressors will be put into service by experienced staff, suitably documented in relation to the manufacturer s declarations and able to understand and apply the instructions contained in the installation manual supplied with the compressor or available on www. frascold.it. Protection of compressors with Diagnose technology Frascold equips semi-hermetic reciprocating compressors with Diagnose technology, which enables a significant step forwards in the compressor protection system and adds new diagnostic and communication functions. Increased protection Frascold compressors are even more reliable. The Diagnose technology monitors conditions inside the system and stops the compressor in the event of incorrect functional parameters. Lower costs Quick identification of the cause of the malfunction. With the information saved on the Diagnose devices, technicians can quickly and accurately diagnose the past and present state of the cooling system, thereby allowing for quick and cost-effective intervention time with short downtime for the system. More information With the communication systems envisaged by Diagnose technology you can monitor and download the system s operating data in real time. This means that technicians can intervene by improving the efficiency and reliability of the system by diagnosing required maintenance in advance. 3

4 Safety device to control delivery temperature The internal delivery temperature, in certain extreme conditions (such as loss of coolant or extremely high compression ratios), can reach values that can damage the compressor. All models 2V and 2Z are fitted with a temperature probe that is connected to the electronic control module and stops the compressor if the delivery temperature exceeds the set safety limit. Electronic safety device to control lubrication Frascold compressors of the 2V and 2Z series are supplied with an electronic pressure switch of proven reliability to control lubrication. The device efficiently monitors the pressure changes of the lubrication system and stops the compressor in the event of insufficient oil flow. The pressure switch is installed directly on the compressor s oil pump and does not require additional fittings. Lubricating oil All compressors are supplied filled with oil with specific features for cooling fluids and having low carryover. Oil viscosity is suitable to assure perfect lubrication within the application limits of the compressors and are appropriate to their mechanics. Accessories Frascold has selected and developed a comprehensive range of accessories for its compressors, suitable to assure efficiency and reliability in all intended operating conditions.

5 Special features The new two-stage compressors by Frascold, models 2V and 2Z, have been redesigned and re-engineered by eliminating external conduits for interstage circuitry and including an additional liquid injection system. These new features provide the following benefits: Compact: thanks to the elimination of external conduits, the compressor features reduced dimensions. Plus, the absence of welding and pipes protects against refrigerant leaks and heat dissipation, which cause system inefficiency. Liquid injection on the motor side: thanks to the exclusive Motor Cooling System, the motor is injected solely with the exact amount of fluid required to cool the motor. This system, only available on Frascold compressors, prevents the formation of ice on the motor by eliminating damage by oxidation, by condensate in the electrical box and liquid slugging. Injection of liquid in the second stage intake conduit: the amount of liquid injected is enough to optimise efficiency. The compressed gas and injected liquid mixing process is instantaneous and the liquid is not overheated as it does not go through the motor. Sub-cooler kit: all models can be fitted with a pre-assembled subcooler that can be provided installed and connected by the manufacturer or supplied separately. Reliable and sturdy: The new specially designed components make the compressor resistant to all operating conditions within its working range. Quiet: the optimisation of the centre of gravity and the homogeneous distribution of weights ensure low vibrations and low noise. Increased efficiency thanks to the dual liquid injection, purposely designed to optimise the operation of the compressor to achieve maximum performance. Compressor control: there are three versions designed to control the oil pressure switch and protection and diagnostics system to be adapted to the different types of plants. Protection device Differential Pressure Switch Control Frascold ICC Module Kriwan INT9 Diagnose Kriwan INT9TML Diagnose Delta/P-II INT2FR Operating logic Standard Control X X The Differential Oil Pressure Switch (supplied) communicates directly with the Central Control Panel (PCC) of the system. The ICC module sends alarm signals directly to the PCC Diagnostic Control (optional) X X X The Differential Oil Pressure Switch (supplied) communicates directly with the Central Control Panel (PCC) of the system. The ICC module sends alarm signals to the INT9 module Diagnose (supplied as standard and to be installed on the electrical panel of the PCC) to allow for diagnostics on the compressor (alarm log, start-up sequences, etc.). Direct Control (optional) X X X The Differential Oil Pressure Switch (provided as standard) communicates with the INT9TML Diagnose module (provided as standard and to be installed in the electrical panel of the PCC). The INT9ML Diagnose module performs full diagnostics of the compressor (alarms log, start-up sequences, etc.), by acquiring the alarm signals both from the ICC and the INT2 FR pressure switch. 5

6 Motor Cooling System The Motor Cooling System is an exclusive feature by Frascold designed to activate a series of fundamental controls to optimise the functionality and efficiency of the two-stage compressors of the 2V and 2Z series. The system includes the liquid injection control card, the Injection Control Card (ICC), the TA current detector, the AMS motor temperature sensors and the liquid injection valve. Here are the features of the device: Constant and accurate control of the motor temperature. The system accurately and constantly checks the temperature via the AMS sensors located inside the windings. Indeed, the position of the sensors has been specifically designed to identify the most critical areas in terms of overheating, thereby allowing to protect the motor also during the critical start-up stage. Efficient motor cooling. The system identifies when the pre-alarm temperature threshold is reached and activates the injection of liquid in the motor according to optimised amounts and time. Compressor reliability. The controlled cooling of the motor prevents excessive cooling on neighbouring areas, eliminating the risk of frost and resulting oxidation, thereby preventing the formation of condensation in the electrical box of the compressor and the risk of a short circuit. Prevention of burns on the motor. The system identifies when the CRITICAL TEMPERATURE threshold has been reached and stops the compressor in the event of anomalous overheating. Liquid injection monitoring. Thanks to the TA device installed as standard, as well as injecting the liquid as required, the system can prevent this function when the compressor stops due to a malfunction of the compressor itself or due to external system management logics. The ICC module is supplied as standard and already fully wired inside the electrical box.
