In order to better use the floor heating system, it is necessary to select a suitable company in addition to the product category. There are two principles when choosing a company: First, you must choose a professional heating company.

There are many types of floor heating pipes, which will be introduced one by one and explain their advantages and disadvantages.
(1) Cross-linked polyethylene-aluminum-plastic composite pipe (XPAP) - The aluminum layer in the middle has an oxygen Barrier function, and can also improve the internal and external pressure resistance of the pipe to a certain extent, and can maintain the shape after bending in construction, but The bending radius is relatively large, and delamination may occur at the time of installation or when subjected to a momentary high temperature, and the price is also high.
(2) PPR pipe - low price, good high temperature performance, can be welded, but the pipe wall is thicker, it is difficult to bend in the floor heating construction, the resilience is greater, and the thermal conductivity is poorer.
(3) PEX pipe - including PEXa and PEXb two types, good low temperature toughness, more resistant to high temperature than PPR, stress cracking resistance is good, but the raw materials have been crosslinked, can not be recycled, can not use hot melt connection, generally used Copper pipe fittings, long-term use prone to leakage.
(4) PERT tube - retains the advantages of the PEX tube, but no cross-linking occurs, the tube can still be connected by hot melt, the joint is reliable, less prone to leakage, flexibility and low temperature resistance is also good.
(5) PB tube - PB material has excellent performance and has the reputation of "plastic gold". PB tube light weight, pressure resistance, impact resistance, low temperature resistance, high temperature performance, long-term use at 95 °C, the maximum use temperature of 110 °C, flexibility is the best of several commonly used warm tubes, the use of hot melt The connection is reliable, but the price is higher due to raw materials.
From the above comparison, it can be seen that the PERT and PB tubes have better overall performance in these 5 kinds of commonly used warm tubes, and especially the PB tubes are more suitable for various high-grade buildings. In addition, considering the oxygen barrier performance of floor heating pipes is also an important performance, PERT or PB pipes with oxygen barrier layer (such as EVOH) can also be selected.
The floor heating system is more complex. From the design of the plan to product selection, construction installation and after-sales service, the overall effect will be greatly reduced if there is no professional participation. Therefore, choosing a professional floor heating company is the most critical guarantee. Second, select companies with extensive construction experience. The warming effect largely depends on the construction quality. The experienced ground heating company can formulate the most reasonable construction plan according to the structure, orientation and layout of the user's room, so as to achieve a reasonable distribution of thermal energy.

Automatic fare collection gates (AFC gates) ensure that the correct travel fare is deducted from the smart cards. It also helps to restrict the flow of commuters to and from the paid area.
Wide AFC gates allow commuters in wheelchair, prams, trolley, luggage or carrying bulky items to access the paid area with ease. As technology advances, newer fare gates in Singapore have been equipped with additional features and sporting a more modernised design.
Fare Gate include Flap Barrier , Swing Barrier ,Tripod Turnstile,Full Height Turnstile,Glass Turnstile, Speed Gate ,Security Turnstile and so on.
