Heat recovery unit
The heat recovery unit, also known as “recuperator” is an air-to-air plate heat exchanger. When a heat recovery unit is installed, the air that is leaving the chamber exchanges heat energy with the air coming into the chamber. In this way, the outside air enters the dryer with higher temperature than the outside. This way heating energy is saved up to 30%. Heat recovery units are completely made of aluminum with a special core and two fans for air exchange. The operation of the recuperator is controlled via a circuit breaker and a frequency inverter, so that they work according to the principle of PI regulation. The installation of a heat recovery system is also possible on the chambers of other manufacturers with automatic controllers MC-2000 / 3000. The installation of these systems provides reserves of thermal energy on the boiler and thus the expansion of drying capacities. Apart from apparent heating energy saving, use of recuperators also shortens time of drying and increases drying quality of timber. Investment in heat recovery units is minimal and return of investment period is very short.
