Is the radiator installed according to a column or a group?
First of all, let us first understand the basic concept of the number of radiators: what is a "pillar" and what is a "group."
The column we are talking about is generally referred to as a steel column radiator. We call a monolithic radiator a column. Usually columnar radiators have a column height from 400-1800mm, which can be customized according to the requirements of consumers.
The so-called group is a single-column radiator with the same specifications connected together. Usually the number of radiators to be installed in a room can be based on the total heat dissipation required by the entire room, divided by the heat dissipation of a single-column radiator. Calculate the number of columns needed for the room and then group the single-column radiators. Usually only one set of radiators is installed in a room.
The above is the representative meaning of a column and a group of radiators. Each group of radiators is composed of a column-by-column radiator. Radiator installation fees are charged in groups, regardless of the number of column radiators in a group.
How much is the radiator fitting?
Radiator installation consists of many accessories, such as pipe fittings, valves, elbows, tees, running wind, plugs, expansion screws, hooks, etc., in which running wind, plug, screw, hook are generally free from the radiator manufacturers Distribution, pipe fittings, valves, etc. need to be purchased separately, according to the actual amount of radiator installation charges, the price of these accessories by the material, brand and other factors, we must not ignore the purchase, the quality of accessories directly affects the level of Radiator daily use and service life, it is best to buy high-quality, big-brand products - Rosad radiator.
Radiator installation costs need to be settled separately.
With the increase of labor costs year by year, the cost of radiator installation workers has also increased year by year. Many consumers say that you should install the heating system for your heating. It is unreasonable to settle the problem with the master alone. In fact, as a consumer, we think about it carefully. The wool is on the sheep. The sellers who can install the package must have increased their expenses in other places. Therefore, it is not as transparent as the price of the radiator. The radiator installation fee can be negotiated with the installation master. The itemized charges are more detailed and reasonable.

High Speed Door Motor And Control Box
Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.
About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.
About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: ＜16 ㎡; Daily operating time: ＞2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.
The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.
System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.
Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.
The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.
Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.
Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.
High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.
Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
