Refrigeration R290 – Full INVERTER R290 Chiller
Jose Miguel Molina2024-07-31T13:55:04+02:00In the field of industrial and commercial refrigeration, innovation and sustainability are key aspects that make the difference. INTARCON, a leading company in the sector, has developed the Full INVERTER R290 Chiller, a unit that incorporates advanced technologies to offer optimal and efficient performance. This system is distinguished by its use of natural refrigerant R290, known for its low Global Warming Potential (GWP), thus contributing to greater environmental sustainability in the long term.
Full INVERTER R290 Chiller
The Full INVERTER R290 Chiller not only stands out for its commitment to the environment, but also for its high energy efficiency and its ability to respond precisely to cooling demands. Equipped with semi-hermetic compressors and frequency inverters, this system allows detailed control of the glycol supply temperature, adapting to variations in demand throughout the year. Full Inverter technology avoids abrupt starts and stops, providing a soft start that significantly reduces start-up intensity and, therefore, energy consumption.
In addition, INTARCON has integrated its own programmable electronics that facilitates the installation and operation of the equipment. The ability to combine and integrate this system with hydraulic and generator sets, together with the possibility of digital and analogue readings, makes the Full Inverter chiller plant a versatile and robust solution for various industrial and commercial applications. The commitment to digital design and the implementation of digital twins makes it possible to anticipate possible failures and make continuous improvements, thus ensuring maximum reliability and efficiency of the equipment.
What is the Full INVERTER system?
El sistema Full INVERTER proporciona un control preciso sobre la temperatura de suministro de glicol, frente a una demanda frigorífica variable. Este sistema controla de forma secuencial y simultánea la capacidad de los compresores, variando la velocidad del motor de 30 a 70 Hz, y evitando los arranques y paradas, con un importante ahorro energético.
What are its components?
In this video our colleague José Aceituno will explain where the components are located and what their function is in our Full INVERTER R290 chiller, model MWW-FD-20802, a glycol chiller plant for commercial and industrial refrigeration applications with a reduced R290 load and Full INVERTER compressors.
What are its characteristics?
- 400V 3 50Hz power supply. Available in 60Hz. Others voltages by request.
- Reduce refrigerant charge of R-290.
- Self-supporting body made of galvanised sheet steel with polyester weatherproof paint.
- Separate compressor compartment with leak detector and ATEX extraction fan
(optional in WW series). - Semihermetic R-290 compressors with unloaded start-up, with ATEX class crankcase heater, with Inverter drive in each compressor (Full INVERTER).
- Cooling circuit made of annealed copper tube with soldered connections, filter drier, ATEX high and low pressure switches, pressure transducers and temperature probes, and ducted safety valve by cooling circuit with common discharge.
- In WW without acoustic panel, one leak detector is equipped in sizes 1 and 2, two detectors in sizes 3 and 4, and three detectors in size 5. In WW with acoustic panel, a single detector and an ATEX centrifugal exhaust fan in continuous operation are equipped. In WT, a single detector and ATEX axial extraction fans in continuous operation are equipped.
- Microchannel condenser coils with Polyester Powder Coating treatment.
- Variable flow electronic fans.
- Stainless steel plate evaporators with electronic expansion valve.
- Hydraulic circuit made of copper pipe with threaded connections, fill/drain valve, air vent, flow switch, thermometers and inlet/outlet pressure gauges.
