EUROVENT CERTIFICATION

This product has been certified by Eurovent.

RC GROUP SpA participates in the EUROVENT program for: LCP and HP (Liquid ChillingPackages and Heat Pumps).Check ongoing validity of certification on -line: www.eurovent-certification.com

GENERAL CHARACTERISTICSFRIGO TURBO FL: Water cooled liquid chillers equipped with oil-free centrifugal compressorsand flooded evaporator

The machines are made for indoor installation.

Framework with sections of thick steel for high resistance to the greatest stress during handling andtransport.

Machines supply fully assembled with refrigerant charge and control systems. The installationrequires only electrical and hydraulic connections allowing costs and time savings.

Final assembly on all machines before shipment including running test, reading and monitoring ofoperating parameters, alarms simulation and visual check.

Design, assembly and test as per the Company Quality Assurance program in full compliance withISO 9001. RC Group has been the first Italian company in its segment to get the ISO 9001 inOctober 13

th, 1991 with certificate ICIM 0018.

The machines are in full compliance with European Norms 2006/42CE, 2006/95CE, 2004/108CE,97/23CE and subsequent amendments.

technical data table.65 ÷ 120% “Extended” water flow range compared to the nominal value reported in the

technical data table.

WARNINGThe deviation of the water flow from “ideal” range towards “extended” range can cause aremarkable performance worsening. Please contact the RC GROUP CommercialDepartment to verify operation conditions.

ANTIFREEZE MIXTURES

EVAPORATOR HYDRAULIC CIRCUITMachines can work with antifreeze mixtures although not necessary, because the machines donot accept outlet temperature of the liquid cooled below 4°C, the use of glycol mixture is ageneric antifreeze protection, for machines not in operation during the winter season.

CONDENSER HYDRAULIC CIRCUIT

In case of heat exhaustion through a close hydraulic circuit on a dry cooler, is mandatory to loadthe circuit with antifreeze mixture.The choice of glycol percentage may be based on the following table:

Freezing point [°C] % Ethylene glycol volume % Propylene glycol volume

-10 24 27

-20 36 39

-30 46 49

 _______________________________________________

STORING TEMPERATURE

If the machine is not installed on receipt and is stored for a long time, store it in a protectedplace, at temperatures ranging between -30°C and 50°C in absence of superficial condensationand direct sun light.

MICROPROCESSOR CONTROL SYSTEM

The microprocessor controls the machine guaranteeing on the one hand a precise and punctualtemperature regulation, on the other hand integrating the safety functions relative to all fluid-dynamiccircuits.The microprocessor controls the outlet temperatures of the chilled water through two set

parameters, xK1 e xK2, as outlet temperatures from the evaporators, with possible remotecommutation through voltage free contact.In any case, the microprocessor will modulate the electric input to the compressors motors toguarantee the maximum temperature precision in respect of the working range allowed by thecentrifugal compressors.For any working condition, the control will cleverly manage the number of compressors to beactivated in a combined optics of safety and energy saving.

The system includes:Compact controller for DIN rail mounting 24Vac 50/60Hz32-bit microprocessor2 +2 MB flash memory (retains data without power) and memory RAM 512kBIntegrated “Data logger” function for the recording of events and alarms. Graphic touch screen colour display 7”
