CFR-HPEI
Therefore, by a single independent system and at the same time, it can match the needing of ventilation while ensuring room comfort, the outside air thermal loads and the energy saving, due to the very high unit efficiency, both on winter and summer time.
Together with their compact dimensions, the characteristics of these units make the plant installations easier, especially when they are really difficult (and much more expensive) by using common heating/cooling systems.
In the new guise, the CFR-HPEI allows even greater accessibility the electrical panel for easier maintenance.
These units can be perfectly integrated into traditional room heating/cooling systems, placed in sequence or in parallel.
CFR-HPEI series is composed of seven sizes, horizontal version only, to cover a needing of ventilation from 300 up to 5400 m3/h.
The unit is very efficiency and flexible mode of operation, thanks to variable flow BLDC rotary compressors with driver and EC motor fans, allowing more logic control options.
The models of the series CFR-HPEI can be given with a ionization system of the air called BIOXIGEN®.
This system, unique in his type, makes the air and surfsces of the machine, of the ducts and of the bordering rooms healthy and good smelling.
-
•Sandwich panels, 23 mm thickness, galvanized sheet metal inner skin and precoated sheet metal outer skin; 45 kg/m3 density foamed polyurethane as heat and sound insulation.
•Direct driven double inlet EC motor centrifugal fans with dedicated driver; constant air flow rate as standard operation (except size 35 and 60).
•First step of energy recovery (static type) by air-to-air crossflow aluminium heat exchanger; lower drain tray, estende to the whole area of heat treatment.
•Second step of energy recovery (dynamic type) by air-to-air reversible heat pump system composed of electric driven rotating compressor with BLDC motor and dedicated driver, evaporating and condensating reversible Cu/Al finned coils, electronic expansion valve, liquid receiver and separator, 4-way reversible valve, high and low pressure switches and sensors, biflow drier filter, liquid indicator.
•Built-in electric box to control power loads, NTC temperature sensors on both air circuits, electronic controller to control room temperature, heating/cooling mode, defrost cycles and timer control system; built in control panel.
•Display control and new electrical box optimized for better heat dissipation and increased accessibility for the operator; also facilitated the connection to main board for the accessories.
•Logic control specially designed for reducing electrical consum- ption and adjusting the working capacity to temperatures, humidities and the ambient crowding (option); alternative possibility for thermoregulation in function of return/ambient temperature or supply temperature fixed point.
•Modbus RTU PCB interface (optional) for supervision of the operative parameters in real time.
