5 ANTIFREEZE MIXTURES EVAPORATOR HYDRAULIC CIRCUIT Machines can work with antifreeze mixtures although not necessary, because the machines do not accept outlet temperature of the liquid cooled below 4 C, the use of glycol mixture is a generic 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 load the 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 STORING TEMPERATURE If the machine is not installed on receipt and is stored for a long time, store it in a protected place, at temperatures ranging between -30 C and 50 C in absence of superficial condensation and direct sun light. 5

The combination of the optional accessory RILHEVA with Master Plant SEQuencer allows: The entire plant or units real time unattended monitoring of the main physical data (pressure, levels, temperatures, failures, unit conditions, ) even in mobility, everywhere in the World, through an easy web access from PC s, tablets or smartphones; The system performance analysis over time, charts creation and export. Units remote control. For further information please consult the chapter on RILHEVA in this catalogue. APPLICATION FIELDS The sequencer can be applied to: 2-pipe and 4-pipe plants; In parallel installed units; Up to 5 liquid chillers, even different in type and size; - Liquid chillers; - Heat pumps and multifunction units; supplied by other manufacturers, different from RC Group; Fixed speed and variable flow pumps. Dry coolers. The sequencer CANNOT be applied to: In series installed units. Air conditioners; Rooftop units; Air handling units; The device is designed to work in standalone mode or in combination with a BMS supervisor: It can work in standalone mode with its own graphics interface and its own 7"graphic touch screen display. It can be linked to a supervision system using BACnet or ModBus protocols (serial port are supplied as options). Master Plan SEQuencer Installazione in cabinet dedicato The software interface is available in English.
