DESCRIPTION

EKR boilers were designed for users having very small boiler rooms. The main advantage of the EKR boilers are minimal dimensions and simple servicing limited to the firing of automatic furnace and removal of ash. Boiler’s heat exchanger is made of boiler steel of thickness 5 mm and structural components of retort burner are made of high-quality heat-resistant cast iron. Boiler is intended for automatic combustion of eco pea coal of grain size 5-25mm. Automatic furnace is cyclically supplied with small portions of fuel directly to the grate of retort, while forced draught fan supplies precisely selected amount of air to the specified areas of the furnace. It allows obtaining high efficiency of combustion process and extraordinary low emission of noxious substances.
Microprocessor controller is used for supervision of combustion process and maintaining of temperature set for boiler.

	5 years of warranty for heat exchanger tightness, 2 years for the remaining components and efficient operation of boiler
	heat exchanger made of certified boiler steel
	electronic control of boiler servicing of two pumps
	high thermal efficiency reaching 87% thanks to increased heat recovery from flue gases
	large combustion chamber with highly effective retort burner
	exchangeable substitute grate made of high-quality cast iron;
	screw of fuel feeder completely made of one piece
