ÜKYS/3G-Y Series Central Heating Automatic Loading Cylindrical Boilers
Product Code: ÜKYS/3G-Y

ÜNMAK ÜKYS / 3G-Y three-pass heating boilers produced with superior technology comply with EN 303-5 and TS 497 Standards. The special cast iron crucible (furnace) design makes it suitable for burning any type of domestic and foreign lignite and ensures complete combustion.

It is designed to burn solid fuel, between 10 and 25 mm, known as rice coal, hazelnut coal.

It provides healthy burning with automatic fuel loading. Since it loads according to the thermal need, excess fuel in the combustion chamber is prevented.

It has a compact structure with its prismatic body, making it easy to be mounted in narrow spaces.

Thanks to its three-pass structure, it increases the surface of transferring heat energy from smoke to water and reduces emissions.

The heat transfer surface area is increased with the flame smoke pipes, thus the efficiency is increased.

It provides more precise thermostat control with its digital control panel. It allows intervention to loading settings according to fuel quality, and sends the most appropriate amount of fuel to the combustion chamber. When it reaches the set temperature, it stops the fuel supply and the fan, and when the temperature drops, it activates these parts again and continues the heating from where it left off.

Thanks to the fan, it reaches the set temperature faster and provides combustion optimization.

With the option of connecting the room thermostat, the comfort of adjusting the boiler water temperature remotely is provided.

Thanks to the heat insulated body, keeping the temperature emitted from the boiler surface inside saves fuel.

If the outside temperature is high, the boiler can be closed from the control panel. In this case, the burning of the fan is darkened when the fan shuts down and the burning is delayed. When the need for heat arises again, the boiler is opened from the control panel and continues to burn without the need for ignition and reaches the desired temperature in a short time (burning delay can be done up to 24 hours depending on the coal quality).

Thanks to its automatic stop feature, the control panel detects when the fuel runs out; fan and circulation pump stop automatically. This feature saves energy.

Fuel filling, ignition, ash removal and pipe cleaning can be done easily thanks to the easy-to-use large filling, pipe cleaning and ash removal covers.

Its elegant appearance and protection against rusting is provided by covering the body plates coated outside of the boiler with electrostatic powder paint. Boiler surfaces are protected with special wet paint.

It provides the opportunity to obtain hot water with the addition of hot water storage tank.
