The lineup
Before talking about the model range of devices from this manufacturer, it should be said that there are several lines of Centek split systems:
wall;
The first model that I want to talk about in detail is the Centek CT-65A09. The cooling capacity here is at the level of 9000 btu. If we talk about power during cooling, then it is equal to 2650 W, and during heating - 2700 W. Power consumption for cooling is 825 W, and for heating - 748 W. The maximum airflow is 7.5 cubic meters per minute. The noise level of the outdoor unit during operation is 50 dB, and the indoor unit is 24 dB. In addition, there is an anti-mold mode, as well as healthy sleep. If we talk about this mode, then during the sleep of the owner, the air conditioner gently raises and lowers the temperature so that the comfort during sleep is maximum.
The model with the index Centek CT-65A07 is practically similar to this model in terms of characteristics.Here the cooling capacity is at the same level as the heating and cooling capacity. But the consumption will be somewhat less - 650 W in cooling mode and 610 in heating mode. The main modes of a split system are heating and cooling. But the maximum air flow here is slightly less than in the model discussed above - 7 cubic meters per minute. The noise level here will be slightly less - 48 dB for the outdoor unit and 22 dB for the indoor unit.
The third model that I want to talk about is the Centek CT-65A12. According to the index, you can understand that it should be more technologically advanced than the 2 already mentioned. In fact, it is. The performance of this model in BTU is 12000, both for cooling and heating. The rated power of this model is 1106 watts for cooling and 1011 for heating. The maximum input power here is 1750 watts. If we talk about the noise level for the indoor unit, then it is 27 dB, and for the external one - 52 dB. This model has the following features:
- auto restart;
- Turbo mode;
- antifungal function;
- 4 operating modes: heating, drying, ventilation and cooling;
- automatic defrosting;
- freon leakage protection function;
- iFeel function.
Another model from this Chinese manufacturer, which began production in 2019, is the Centek CT-65D07. One of its features will be that the recommended area for work here is 26 square meters. meters. Power consumption in cooling and heating mode is 825 and 748 W, respectively. If we talk about the total power, then in cooling mode it is 2650 W, and in heating mode - 2700 W.Another feature of this model is that there is a fairly low noise level during operation - about 24 dB.
Also an interesting model that may be of interest to buyers is the CENTEK CT-65A18. This split system has a cooling capacity of 18000 btu. If we talk about indicators of power consumption, then when cooling, the figure will be 1656 W, and when heating - 1509 W. This is a single-phase device that can operate in cooling and heating mode. The power in heating mode here is 5450 watts, and cooling - 5300 watts. The maximum airflow is 13.33 cubic meters per minute.
A good model, which is similar to some of the ones mentioned above, is the CENTEK CT-65B09. The cooling capacity of this model is 9000 btu. When cooling, the device consumes 825 watts, and when heating - 748 watts. If we talk about power in cooling and heating mode, then it is 2650 and 2700 W, respectively. The maximum airflow that is possible here is 7.5 cubic meters per minute. This model also applies to a single-phase split system, like other models of the manufacturer.
Features of Centek air conditioners
All devices from this manufacturer have five main modes of operation:
- cooling - if the temperature exceeds the set value by 1°C, then the cooling mode is activated;
- heating - if the air temperature is lower than the set value by 1°C, then the heating mode is activated;
- automatic - temperature stabilization in the range from 21°C to 25°C by turning on cooling or heating;
- ventilation - the flow of air without changing its temperature; this mode is set manually or there is an automatic switch to it from the previous three modes when there is no need to heat or cool the air;
- dehumidification - extracting excess moisture from the air and removing it through a special tube to remove water.
The temperature measurement can be made using two sensors. One of them is located on the body of the indoor unit, and the second is integrated into the control panel.
The quality of its work and trouble-free service life depend on the correct installation of the split system. In the absence of skills, it is better to use the services of specialists
Also, all models have three additional options:
- Super. Activate intensive mode, which works in conjunction with heating or cooling.
- Eco. Economy mode. In fact, savings are achieved by increasing the range of permissible temperatures. So, when the air conditioner is set to 22°C, the cooling start will work if the value exceeds 24°C, and in heating, if the temperature is below 20°C.
- Sleep. Sleeping mode. Within two hours, the air conditioner either lowers or raises the temperature by 2 degrees (depending on cooling or heating operation), and then stabilizes it.
For all wall-mounted models, there are two standard remote controls, which makes it easier to purchase them in the event of a breakdown of the remote control that comes with the air conditioner.
All the information necessary for setting up and operating the split system is displayed on the remote control. Therefore, the display on the front panel of the indoor unit can be turned off
Many Centek air conditioners are equipped with outdated rotary compressors.This significantly reduces the cost of the entire system, but increases power consumption.
To justify the choice between a modern inverter system or a conventional rotary system, it is necessary to calculate the difference in consumption and convert it into a monetary equivalent according to the current tariff. It is better to purchase rotary systems if the operation of the air conditioner is rarely needed.
With frequent load, it is better to use a more expensive inverter analogue, which, in addition to saving electricity, has a number of advantages:
- longer warranty from the manufacturer;
- less chance of breakage;
- less noise from work.
Another feature of Centek air conditioners is the use of Toshiba motors, which are not made in Japan, but at the Chinese GMCC plant.
After the Chinese company Midea bought out a controlling stake in this enterprise, only technology and the ability to use the brand remained from the Japanese giant, which manufacturers from Centek and many other little-known companies took advantage of.
The type and manufacturer of the compressor are indicated in the technical documentation for the air conditioner. This data should be trusted more than advertising brochures
It must be admitted that the quality of rotary compressors from GMCC is often criticized, but this is less true for inverter models.
Therefore, in the case of choosing a device with such a motor, it is better to follow a few simple rules:
- Do not give a long maximum load. It is better to choose a split system with some margin for the area of the serviced premises.
- Clean the filter according to the instructions - at least 1 time per 100 hours of operation. If there is a lot of dust, this should be done more often.You can reduce the amount of impurities in the air by installing an autonomous humidifier.
- Take advantage of the possibility of extending the warranty period, if feasible. For example, for the CT-5324 system, the manufacturer's liability for failure is 1 to 3 years.
Another aspect to consider when buying Centek air conditioners is that their cost should be lower than that of well-known brands of similar power.
Sometimes retailers greatly inflate prices for budget devices. So, for example, the CT-5909 model can be found in the range from 13 to 20 thousand rubles. You should not overpay for split systems from this manufacturer.
Advantages and disadvantages of technology
The review of the Centek CT-65A09 model, as well as customer reviews, make it possible to judge the pros and cons of the system.
So, the positive qualities of the device include:
- classic appearance of the room module and high-quality, easy-to-clean panel;
- reliability and high performance of the compressor from the Japanese manufacturer;
- remote control display backlight;
- compact dimensions of indoor and outdoor units;
- almost silent operation of the room module;
- economical energy consumption.
A significant advantage of the monitored device is a quite acceptable and affordable price for most users for a modern and functional device.
The undoubted distinctive superiority of the model over its business-semgent competitors is its equipping with a powerful, reliable and durable rotary-type compressor from the Japanese manufacturer Toshiba
In fairness, it is necessary to note the negative statements regarding the split that take place in some user reviews:
- small length of the power supply cable from the 220 V network;
- no additional filtration;
- poor quality of the material from which the drain tube included in the kit is made.
One of the users complains that in less than two years, under the influence of sunlight, this drainage outlet has become unusable. Advice - to equip the condensate drain from metal-plastic.
There is a single complaint about the low performance of the device and one complaint from neighbors about the noisy operation of the outdoor unit. Most likely, these claims are in the nature of subjective judgments, or they are related to the malfunctioning of the units.
As directed to the sellers of climate control equipment, a comment is accepted on the existing complexity in ordering and purchasing this model on some Internet services for the selection of goods. The reason is that the main offers for the sale of the device are posted on the trading floors of regional markets.
Peculiarities
If we talk about the features that Centek split systems have, then they can be described using the example of the Centek CT-65A09 model. For example, this model, like some others from this manufacturer, belongs to the Air line, the production of which is concentrated in China, or more precisely, at an enterprise in Guangzhou province. Any feature here would be better than the models released a few years earlier. This suggests that the manufacturer is constantly improving the device of the produced models and is trying to offer a potential client better split systems.
Naturally, the use of various innovations and new technologies makes it possible to increase the efficiency and safety of the split systems of this manufacturer. Another feature of the Centek split system models is that very serious quality control is carried out at all stages of the creation of such equipment. In addition, when creating split systems, only reliable and proven materials and components are used here. Another feature is that the manufacturer gives a guarantee for its equipment for 3 years.
Another important point that does not contain a description of this Centek split system model is the use of special refrigerants in the devices. In this case, we are talking about the use of the most energy-efficient R410A freon, which does not pose a danger to either humans or the environment. In general, as you can see, the split systems of the manufacturer in question have a certain number of features that favorably distinguish them from the products of other companies that produce split systems.
Instructions for use
Note that for models of various series, the company has created a single instruction describing all the technical characteristics, safety measures, various components, as well as the rules for caring for the air conditioner. Thanks to the detailed manual that comes with each model of air conditioners, life-threatening situations can be avoided. All manuals are written in a simple language that will be understandable even to a person who has not previously used such a device.
It should be remembered that according to the instructions it is forbidden to wash the module itself or the remote control or its buttons under running water.In addition, materials such as gasoline, alcohol, various kinds of abrasives and hot water with a temperature of more than 45 degrees cannot be used to maintain plastic so that it does not deform and lose color. When installing a split system, the difference in levels between the blocks should not be more than 5 meters. In order to reduce energy costs, as well as to minimize the possibility of condensate accumulation on the surface of the inter-unit route, which will significantly reduce the operating time of the connection nodes, experts propose to carry out the insulation of the communication route.
For carrying out thermal insulation of tubes made of copper, a rubber-based thermoflex is usually used. The connecting line, which consists of a pair of insulated pipelines, an electrical cable and a drainage pipe, is tied with Teflon or bandage tape. Due to the large number of materials for track insulation, there are no difficulties in finding them. The piping of the split communications is carried out as carefully as possible in order to prevent damage to the copper tubes. It is better to entrust this work to specialists.
If we talk about working with the indoor module, then it should be said that in no case should you turn on the split system again during the dehumidification until it is completely finished. Another important point that should not be neglected in any case is not to use a smartphone or mobile phone near the internal module due to the fact that interference from it can cause malfunctions in device control.But if for some reason a failure did occur, the manufacturer recommends rebooting the device by turning off the air conditioner from the network.
Comparison with competitive models
Therefore, below will be given the possible contenders for leadership in relation to Centek Air, but located in approximately the same price segment, called the budget, equivalent in type - non-inverter, and wall-mounted models similar in performance.
Competitor #1 - Ballu BSD-09HN1
The device is produced by an international concern with a representative office and production facilities located in China. The model belongs to the 2018 Lagoon series.
In terms of service area, the unit is almost equivalent to the device from Centek - 26 m2, and is also equipped with a solid compressor from GMCC-Toshiba.
Main Specifications:
- productivity for cooling / heating - 2.78 / 2.64 kW;
- cooling / heating power - 0.82 / 0.77 kW;
- the minimum air temperature for operation during heating is minus 7 °С;
- noise level of the internal module - 26 dB;
- the ability to connect control over Wi-Fi - yes.
The model looks a little more solid due to the equipment of the indoor unit with a high-density pre-filter and a good rating in the market.
