Description
EKO MAX boilers are eco-pea boilers designed for heating large-format surfaces. The Eko Max boiler is built from high-quality certified steel sheets. It consists of two parts: a combustion chamber, where all fuel combustion processes occur supplied by the feeding system with air intake, and a convection section which forms a two-flue, horizontal flame tube heat exchanger, which transitions into a chimney at the rear of the boiler. The combustion chamber door is equipped with a viewing glass, through which we can monitor the flame condition in the combustion chamber. To reduce heat loss, the external part of the boiler is insulated with steel sheet casing, under which thermal insulation is placed. The furnace also has an electronic controller, which monitors the temperature height in the boiler and adjusts it accordingly. It also controls the operation of the C.O. and C.U.W. pumps.
Standard equipment:
- CO, DHW pumps and 1 additional pump,
- GSM Module,
- weekly operation,
- PID program,
- Ethernet Module,
Optional equipment:
- additional valve module control,
- room controller with RS communication,
- room controller
Standard equipment:
4 years warranty on heat exchanger tightness, 2 years on remaining components and proper boiler operation;
heat exchanger made from certified boiler steel
Designed for heating large-format buildings
