Ductless, direct space heating
Requires no air handling unit or air duct; it heats the space it's in directly by natural convection. A simple, low-maintenance solution.

Radiators
Heating units that transfer the heat of the hot water or steam passing through them directly into the surrounding air by natural convection. The finned tube bundle is housed inside a galvanized sheet-metal casing, giving both a large heat transfer surface and an impact-resistant structure.

Why it matters
What does a radiator do?
Without needing ductwork or an air handling unit, it heats the space directly by transferring the heat of hot water or steam into the air.
Economical heating for factory and warehouse spaces
In large, high-ceilinged spaces such as workshops, warehouses and hangars, it can be placed at specific points or along a line to provide heating at a low operating cost.
Integrates directly with the boiler room or central circuit
Connects directly to the hot water or steam circuit coming from an existing boiler room or central heating line; no additional conversion equipment is needed.
Flexible, size-specific installation
With floor-standing or wall-hung mounting options, it adapts to different placement needs in spaces with limited floor area or high ceilings.
Types
Sub-types of radiators
All three heat by natural convection through a finned tube bundle; what sets them apart is the heat source (water/steam) and the size/mounting requirement.
Hot water radiator
Running on the standard hot water circuit from the boiler room, the most common type for factory and warehouse heating.
- Copper/steel tube + aluminum fin construction
- Floor-standing or wall-hung mounting
- Suitable for a wide capacity range
Steam radiator
Fed from a steam line, with a high heat transfer capacity, this type requires condensate drainage (a steam trap).
- High thermal capacity
- Planned together with a steam trap
- Preferred in process and warehouse areas
Project-specific radiator
A custom-built type for length, height or capacity needs that standard sizes don't cover.
- Length/width sized to the space
- Custom mounting hardware
- Used for drying and process area heating
Selection criteria
What data determines the right radiator?
Capacity alone isn't enough. Once the six points below are clear, the choice narrows to a single model.
ParameterWhy it mattersWhat we need from you
Heating capacity
The space's heat loss together with the target indoor temperature determines the capacity. An undersized radiator won't reach the target temperature.
kW and volume/m² data
Fluid type and temperature
Whether hot water or steam will be used; for water, the inlet-outlet temperature determines the tube-fin combination.
Hot water (e.g. 80/60 °C) or steam pressure
Operating pressure
The circuit's operating pressure determines the tube wall thickness and connection class.
PN6 / PN10 / PN16
Mounting style
Whether it will be mounted floor-standing or wall-hung changes the casing and bracket design.
Floor-standing / wall-hung / wall type
Space characteristics
Ceiling height, the size of the space and its heat loss determine the number of radiators and their layout.
m² / m³ and ceiling height
Connection size
The connection size and orientation to the existing installation line must be clear from the start.

FAQ
Questions from the field
The questions we hear most often when quoting radiators.
What is the difference between a radiator and a heating coil?
Both work with a finned tube bundle; the difference is where the air movement comes from. A heating coil works with air forced through it by an air handling unit or a duct; a radiator needs no duct and heats room air directly by natural convection.
What kinds of spaces are radiators preferred in?
In large-volume spaces such as factories, workshops, warehouses and hangars, where a central ducted system isn't economical; also preferred for drying environments and process area heating.
Should I choose a hot water radiator or a steam radiator?
This depends on your existing or planned heat source. If there's a hot water circuit from the boiler room, a hot water radiator is used; if there's a steam line, the steam type is preferred, planned together with condensate drainage (a steam trap).
How is radiator size determined from the volume of the space?
The space's heat loss is calculated to find the total capacity needed (kW); this capacity is usually met with several units distributed along the line rather than one large radiator.
Do you only serve Istanbul?
No. While our office is on Istanbul's Anatolian side (Ataşehir), we supply and ship across Istanbul's European side, the surrounding provinces and the Marmara region, and Turkey as a whole — covering your equipment end to end, from a single source.
