Features of Radiator
Easy Maintenance, High Efficiency & Cost-Effectiveness
The unique design allows rapid isolation, disassembly, repair, or replacement of individual radiator groups without draining the transformer's insulating oil. This minimizes equipment downtime, simplifies on-site maintenance into straightforward module replacement, and substantially lowers operational costs.
Modular Design, Flexible Expansion
Featuring a standardized modular design, the radiator allows flexible configuration of cooling groups based on actual transformer thermal requirements. For future capacity upgrades, additional modules can be easily installed to enhance cooling performance, protecting the initial investment.
Excellent Performance, Stable & Reliable
Manufactured with premium steel and advanced techniques, the radiator ensures high thermal conductivity and structural integrity. The fin design is optimized through fluid dynamics for maximum heat dissipation efficiency. Rigorous sealing tests guarantee reliable, leak-free operation under diverse working conditions.
Quality Assurance, Wide Application
The product complies with relevant national standards and industry specifications. Suitable for oil-immersed transformers from 35kV to 500kV, it is widely used in power stations, grid systems, industrial facilities, and new energy projects, serving as a key component for enhancing transformer reliability.
Radiator Body (Panel)
The radiator panel is the large, flat metal surface you see on your wall. It' s usually made of steel and is where most of the heat comes from. Inside, hot water flows through channels, warming the panel, which then radiates heat into the room. Some models have a single panel; others have two or three for greater heat output.
Convector Fins
Convector fins are thin, corrugated metal sheets attached to the back of the panel (or between panels). They help increase the radiator' s surface area and boost heat transfer. Cold air from the room enters at the bottom, passes over the warm fins, and rises out the top as heated air. Convector fins can come in single rows or double rows.
Top Grille
The top grille is the slotted or louvered cover that runs along the upper edge of the radiator. It' s mainly decorative, hiding the convector fins and helping guide warm air upwards into the room. You' ll often find it on double panel radiators with internal convector fins.
Side Panels
These are the flat covers on the left and right ends of the radiator. They provide a neat, enclosed finish by hiding the internal components and pipework. Like the top grille, they' re mostly for appearance, but also offer a layer of safety.
Inlet Valve (Flow Valve)
This valve is where hot water from your boiler enters the radiator. It' s usually located at one of the bottom corners. It controls how much water flows into the radiator and can be adjusted manually or automatically, depending on the type of valve used.
Thermostatic Radiator Valve (TRV)
A TRV is a type of inlet valve fitted with a numbered control head. It senses the room temperature and automatically adjusts the water flow into the radiator to maintain your preferred comfort level. This helps save energy and keeps the room at a steady heat.
Manual Valve
A manual valve allows you to control the radiator by turning it by hand. It' s a simple on/off or high/low adjustment, without any automatic temperature regulation. It' s often used in smaller spaces or rooms where consistent manual control is preferred.
Outlet Valve (Return Valve / Lockshield Valve)
This valve sits at the opposite end of the radiator to the inlet. It controls how quickly cooler water leaves the radiator and returns to the central heating system. It' s typically adjusted during installation to help balance the system and ensure all radiators heat evenly.
Lockshield Cap
The lockshield valve is often covered by a protective plastic cap. It' s not meant to be adjusted frequently. Instead, it' s set during installation by a heating engineer to balance water flow across your radiators. Adjusting it incorrectly can cause heating imbalances, so it's usually left alone.
Bleed Valve (Air Vent)
The bleed valve is a small screw or cap located at the top corner of the radiator. Over time, air can get trapped inside the system and stop the radiator from heating properly. Using a radiator key, you can release the trapped air (called "bleeding" the radiator) to restore full heat output.
Mounting Brackets
These metal brackets are fixed to the wall and hold the radiator securely in place. They support the radiator' s weight and ensure there' s enough space behind for air to circulate and for maintenance access.
Flow Pipe
This pipe brings hot water from the boiler to the radiator. It connects to the inlet valve and is usually located at the bottom of the radiator. The water flows in, travels through the internal channels, and heats the radiator body.
Return Pipe
The return pipe carries cooler water back to the boiler after it' s passed through the radiator. It connects to the outlet valve and completes the circuit in your central heating system, ready for the water to be reheated and recirculated.
Common Materials of Radiator
Mild steel
Mild steel is the most common metal used in radiator manufacture and, unless you've specifically chosen a different metal for your radiators, is probably what you have in your home.
The most popular type of radiator in the UK's homes is the trusty white, horizontal, convector radiator and these are virtually always made from mild steel.
Mild steel strikes the right balance between heat and economic efficiency, plus it's fairly easy to shape. This makes it the perfect material for manufacturing radiators and why it is used so often.
Stainless Steel
Top quality 304 Grade stainless steel is also fairly commonly used in luxury radiator and heated towel rail manufacture.
Stainless steel is incredibly durable and resistant to corrosion, especially at high temperatures.
Because radiators constantly have hot water running through them, 304 stainless steel is superb at keeping radiators running smoothly for years on end. Indeed, you often find that stainless steel radiators have longer manufacturer's guarantees than other materials.
Stainless steel rads also look great aesthetically. They often come with polished or brushed finishes, both of which can look better and better as they age.
Aluminium
Aluminium is an excellent conductor of heat, making it a great choice for a radiator material.
Radiators made from aluminium can get up to your desired temperature more quickly than other materials, meaning less energy is used during the heating up process.
The fact that aluminium rads are mainly made from recycled metal makes them a popular eco-friendly choice. Plus it's good to know that the aluminium can be recycled again when the radiator comes to the end of its natural life.
Aluminium is a very light metal which also makes it easy to shape, transport and install, so your plumber will likely be pleased they don't have something too heavy to lug up the stairs!
Cast iron
The original radiator material, you still find a lot of old cast iron radiators in hospitals, schools, village halls, stately homes etc...
Many people with period properties choose to install newly-manufactured (but old in style) cast iron radiators because of the character they give to interiors.
Cast iron radiators are incredibly strong and long lasting and can emit heat for a long time even after they've been turned off.
While radiators made from cast iron can look fantastic in the right setting, they are heavy and cumbersome to install, so shipping and installation costs can be more expensive.

Precautions for Installing Radiator
Radiator alignment
Make sure the radiator is properly aligned and leveled in its location. This is crucial for its optimal functioning and to avoid problems with the pipe connections.
Shut-off system
Before starting the installation, ensure that the heating system is turned off and the water pressure is appropriate. This will prevent accidents and potential damage.
Pipes and connections
Use high-quality plumbing pipes and fittings to avoid leaks. Employ Teflon tape or thread sealant on the threads of the connections to ensure they are airtight.
Proper tightening
When tightening the valves and connections, avoid excessive force that could damage the radiator. Use appropriate tools and tighten carefully.
Radiator bleeding
After installation, bleed the radiator to remove any trapped air in the system. This is essential to ensure efficient operation.
Final adjustments
Set the control valves and thermostatic heads (if you use them) according to the heating needs of the room.
