Recuperation systems

They are based on the technology of plate and cross-flow exchangers, made in the special 'for the paint shop' option, without using silicone and with increased spaces /even to 12 mm/ between plates. Their surface is unique press-shaped to prevent permanent fouling with paint dusts and to provide the largest exchange area.

The nominal efficiency of ASTHERM plate exchangers is agreed with the Investor and can achieve even 75%. However, on account of their outstanding price/ effectiveness ratio , we usually use exchangers with the 60% efficiency.

To apply the recuperation system to the existing installation one should be aware, that on account of additional drag to the air flow through the plate exchanger of the air recuperator, a change of commonly used fans to high pressure ones is necessary, and in consequence, also of engines, their drive and the control system.

Talking about recuperation system in a spray booth, we mean the set of necessary modifications that should be done. In the standard spray booth, without the recuperation system, the ventilation efficiency is calculated for a static pressure usually from 300-400 Pa /low-budget booths/ to 700-900 Pa /booths of higher quality/ . In case of using the recuperation unit it is necessary to use fans being able to achieve the assumed ventilation effectiveness at the 1200-1600 Pa presssure / depending on the nominal drag of the plate exchanger/.

Additionally, so-called 'bypass' system is installed in the recuperation unit. This is automatically working system, which in case when temperature difference is too small /in the summer/ passes the air sideways, skipping the drag of the plate exchanger. In combination with inverters controlling the rotation speed of engines /and consequently - with the effectiveness of the ventilation/, and the automatic control of the booth pressure, this reduces an electricity consumption in the drastic way. In this solution there is no need to take the cross-flow exchanger out for the summer period.
