RCI - RNI

This series of chillers and air-water heat pumps fulfils the requirements for medium-power residential or industrial air conditioning and heating systems.

The entire range is available in R410a or in R454b. The latter is a refrigerant gas with a GWP of 466, over 75% less compared to R410a.

All the units are suitable for outdoor installation and can be used in fan coil, radiant and high-efficiency radiator systems or to extract the heat generated during industrial processes.

The cooling circuit, housed in a separate compartment to make maintenance operations easier, features inverter scroll compressors which ensure greater efficiency to partial loads (SEER/SCOP), all the units are in Class A energy efficiency.

The inverter control on the circulation pump and fans (EC Inverter) are also available as accessories for a greater efficiency. The EC Inverter fans are also available with high pressure head for internal ducted installation.

A wide range of accessories, factory installed or supplied separately, complement the extreme versatility and functionality of the series.

FEATURES

- Free-standing structure made of galvanised sheet metal with added polyester powder coating protection.

- DC INVERTER Scroll compressors internal heat protection and crankcase heater.

- Axial fans coupled directly to the motor with external rotor.

- Finned coil with copper pipes and aluminium fins

- Stainless steel AISI 316 brazed plate exchanger, including water differential pressure switch. The anti-freeze heating element is standard supply in the heat pump unit.

- The cooling circuit has an electronic expansion valve, high and low pressure electronic pressure gauges, and R410A refrigerant. Desuperheater for 20% heat recovery and Total heat recovery unit for 100% recovery are available as options.

- Electrical cabinet with main cut-off switch and door lock device, fuses, thermal relays to protect the compressors and thermal contacts for the fans.

- Condensation check included: proportional electronic device for continuous and efficient operation of the unit with external air temperature as low as -20°C in cooling. The device also guarantees the damping of the sound level especially at night. It consists of a continuous fan rotation speed regulator, high and low pressure transducers in the cooling circuit and electric heater in the electrical cabinet

- Heating operation with external air temperature as low as -15°C.

- The unit is managed by a microprocessor controller to which all loads and control devices are connected via a wiring board. The user interface consists of a four-button display via which it is possible to view and, if necessary, change all the unit operating parameters.

- A remote keypad is available, as an accessory, which replicates all the operations of the interface installed on the machine.
