Since the creation of disinfecting devices - irradiators - they have become widely known. Now these devices are used not only for medical purposes, but also in domestic conditions. And not in vain - with their help, you can destroy almost all viruses and bacteria located in the area of the irradiator.
The Russian company "Kront" produces one of such devices - "Dezar", reviews of which leave no doubt about its acquisition. It is a reliable and efficient device designed in a modern style. Next, consider what kind of equipment it is.
Disinfection Devices
Currently, several types of devices for disinfection of air in enclosed spaces are used:
- bactericidal irradiators - devices related to the open type;
- bactericidal irradiators-recirculators - have a built-in fan, belong to closed-type devices;
- models of the combined type, can be used as both previous devices, have a removable screen;
- lamps for quartz processing.
Depending on the type, this equipment can be used either in domestic premises or in medical conditions. For example, the Desar irradiator-recirculator, reviews of which confirm its popularity, can be used in any conditions, subject to modification.
There are several reasons to use disinfection equipment:
- with the help of recirculators, uniform air movement and its effective purification are achieved;
- depending on operating conditions, it is possible to use a wall, combined or mobile type of device;
- devices have a long service life, affordable;
- when used correctly, almost one hundred percent disinfection of air masses occurs, during which viruses, allergens and spores are destroyed;
- silent, easy to operate appliances.
Open type irradiators
Disinfection of medical facilities is carried out mainly by open type devices. The lamp of the device is not protected by a cover and spreads ultraviolet rays at three hundred sixty degrees. This disinfects not only the air around, but also the surrounding objects.
Structurally, they can be used as directional sterilizers by analogy with quartz lamps.
The disadvantage of this type of devices is their open source of light (rays) - people, plants and animals are not allowed to be near the device during operation. In addition, forced ventilation is often required to provide air circulation for uniform treatment of the room.
Short-term presence of people is allowed only near sterilizers equipped with protective screens or with a rotary lamp.
Such devices are used only in medical institutions.
Closed irradiators-recirculators
From the point of view of operation, the safest for humans are closed models, for example, the Desar irradiator. Reviews of this equipment confirm this opinion. Devices are called recirculators. The lamp emitting ultraviolet rays is hidden inside the housing under the protective casing. There, the air stream is cleaned, which is forcedly circulated using the built-in fan.
This principle of operation provides better disinfection. The protective design allows you to not worry about the life and health of nearby plants, animals and people during the use of the device.
Thus, this device can safely be used both in medical institutions and in domestic conditions. The main thing is to choose the right model depending on the properties of the room.
The advantage of this type of device over the rest is that the recirculators are easy to operate, do not require special professional skills, are harmless.
Quartz lamp
One of the varieties of the recirculator is a mercury-quartz cleaner, inside of which quartz glass lamps are installed as a working element . The main focus of the use of this type of equipment is the prevention and treatment of various diseases.
After using these devices, mandatory ventilation is necessary, since harmful ozone is released during their operation.
In contrast to such devices, in Kront's Dezar type recirculators, manufacturer reviews and recommendations confirm this, the installed UV lamps filter ozone radiation and are free of mercury. That is why they are preferable for the home, and mercury-quartz disinfectors - for hospitals.
Prices for the device "Dezar"
Despite its usefulness, not every organization or person could purchase such equipment at the beginning of 2016. After all, the prices for it can not be called affordable.
The youngest model of this device of the old series had a minimum price of about eight thousand rubles. While the most advanced representative of this family reached a value of fourteen thousand rubles.
At the end of the summer of 2016, the Kront company released a new, eighth, line of modern illuminators. The prices of this series have become more affordable and range from four to seven thousand rubles.
Varieties of irradiator of the old Dezar series
Customer reviews say that early devices are not inferior to new ones, except in price.
The first device of this type was released about twelve years ago. During this time, the creators invented many models. To choose one of them, it is necessary to carefully study the characteristics, although the principle of operation is similar for all:
- For domestic premises and offices was created "Dezar 2", characterized by small dimensions and ease of use. It has a safety lamp from the Netherlands - Philips TUV16W long life with a life of up to eight thousand hours.
- Professional disinfection in the premises of the service sector is a task for the Desar 3 illuminator. It is used in crowded places - salons, restaurants, hairdressers and others. It has excellent energy-saving characteristics and high efficiency.
- Safe for people and animals, Dezar 4 is designed to disinfect several adjacent rooms. It is placed in a special trolley in which it can be transported from place to place.
- Models numbered five, six, seven and eight are designed to work only in a hospital environment.
New Dezar models
The manufacturer presents a new series of four models:
- “Desar 801” and “Desar 801P” are wall and mobile models with one 25-watt bactericidal lamp, cheap analogues of the second model, differ in weight due to the cart for mobility (three and a half and six kilograms). The devices are designed for processing rooms with an area of up to forty square meters and a ceiling height of up to two and a half meters (volume up to 80 cubic meters). Efficiency is 95%. They can be used in any premises, from kindergartens and schools to hairdressing salons and treatment rooms.
- “Desar 802” and “Desar 802P” - two disinfecting lamps are included in the design; they are budget copies of devices of the fifth and seventh modifications with a capacity of up to 99%. Lamp power, dimensions, weight and cultivated area are similar to previous models. Designed to work in the premises of laboratories, maternity hospitals, intensive care units, operating rooms. They are slightly inferior in terms of the volume of the machined surface, but they outperform the old Dezar models in efficiency and double the price.
Negative reviews can be heard about the noise level of new devices. In fairness, it is worth noting that it exceeds the noise of the models of the old series by only five decibels and is equivalent to the operation of the refrigerator.
How to choose the right recirculator
To ensure effective disinfection of the room, you need to carefully select the irradiator. A correctly selected device will serve as a prophylaxis of viral diseases, and if the disease has already arrived, it will help a speedy recovery.
The closed-type Desar illuminator for the home meets these goals. Customer reviews recommend that when choosing it, pay attention to such characteristics:
- Performance. The choice of device power should be based on the area of the room where it is planned to be used. It is acceptable to buy a less powerful recirculator, but it will take more time to process it. Normal deviation should be up to 20%.
- Installation method. On sale you can find mobile, wall (mounted above 1 m from the floor or ceiling) and combined irradiators. Each type has its advantages and disadvantages that must be considered when choosing.
- Product Material Metal and plastic are the substances from which the body of the Dezar device is made. Reviews say the former are more reliable and can withstand shock. If there is no risk of mechanical damage, then the choice of the budget version is more relevant.
- Control system. Convenience of management is an important component. The device can show the hours worked, the condition of the lamps and have a timer.
- Additional filtration system. Irradiators are available in different configurations. It is worth paying attention to models with filters for air purification.
- The number of lamps. Devices differ in power and radiation output. It is important to choose the right one for the parameters specifically for the purpose of the buyer.
Rules for using the Dezar device
Customers are wondering, “How often and for how long do I need to turn on the Dezar illuminator?” Reviews on the operation of the device confirm its safety during continuous use, even if there are people in the room. The operating time of the device depends only on the normative indicators of air for a particular room (home room, ward or operating room).
Recirculators are effectively used in rooms up to 100 cubic meters. and in the presence of a maximum of 3 people. If there are more people in the room, then the number of irradiators is calculated as 1 device for every three. When it is necessary to clean a room of more than 100 squares, the calculation of the irradiators is carried out in the ratio of 1 piece for every hundred.
It is important to keep an eye on the Dezar lamps. The reviews note that it is necessary to promptly wipe the inside of the irradiator and the bulb with gauze swabs, moisten them with alcohol or wipe them with a clean woolen cloth.
If the operation of the device is in doubt, you should immediately consult a specialist for advice. Self-repair is not allowed.
Contraindications
A bactericidal irradiator, like any medical device, has contraindications for use. They cannot be ignored. Reviews of the Dezar recirculator confirm that it is necessary to consult a therapist before purchasing.
Firstly, each person is differently sensitive to UV radiation, and secondly, there are diseases in which such radiation is contraindicated:
- individual intolerance / increased sensitivity to ultraviolet may be observed;
- the presence of any type of tumor;
- manifestations of tuberculosis in the active phase;
- any acute inflammatory processes;
- problems with pressure (hypertension of the 2nd-3rd degree);
- diseases of the stomach and intestines, as well as thyroid gland;
- renal failure and malfunctions of the cardiovascular system.
If health problems are not observed, then regular preventive use of the irradiator will beneficially affect all family members, animals and plants.
