MIWE eco : box

Makes good use of your waste gas

The flue gas heat exchanger for all bakehouses

Wherever heat from oven burner flue gas or heating boilers is to be recovered effectively without impairing the baking result, MIWE eco:box is in its element. It is available in different performance classes (for individual oven burners with rated outputs of 95 or 140 kW, or for max. three burners in the 170, 250 and 300 kW variants), and therefore suitable for any company size, from small craft bakers to large-scale industrial baking operations.

What makes the MIWE eco:box so unique

Its extreme durability

Burner flue gas can be very hot. That is why we focused in particular on the durability of the MIWE eco:box. High-alloy V4A steels (for specialists: 1.4404) permit reliable continuous operation. A special immersion pickling increases the durability even further

Reduces the need for chimneys

If multiple burners are connected to a MIWE eco:box, the number of chimneys required (and your chimney sweep costs) are reduced accordingly. 

Measurable improvements

With its large flue gas heat exchanger, the MIWE eco:box recovers up to 70% of the escaping flue gas heat as thermal energy (as hot water). If the recovered energy is used fully, the combined combustion efficiency of the system (oven + MIWE eco:box) is increased by approx. 9% – and even by up to 14 – 15% for central heating boilers. Incidentally, this results in pleasantly short payback times.

Safe even at full load

When water and great heat meet, the result is steam and high pressure. That was reason enough for our engineers to equip our MIWE eco:box with a sophisticated, 2-stage monitored bypass system. Your safety is of paramount importance to us.

Plug and save

Thanks to its compact design, MIWE eco:box can be installed quickly and easily in almost all space situations. The intelligent multi-nozzle system for the connections permits a wide range of different installation locations, depending on what is available on-site.

Hygienically perfect

A robust exterior with high-gloss insulation protects against soiling and permanent deposits (and thus reduces the risk of burns). An integrated control thermostat on the circulating pump also automatically performs a complete cleaning of the interior.
