Fonctionnement

BTHC balanced temperature/humidity control: PID-modulated SSR holds heating/humidification equal to thermal/moisture losses for long-term stability. Multi-vane centrifugal recirculation fan with high-temp aluminum-alloy blades on reinforced shaft drives forced convection; FLOW THROW air pattern – horizontal diffusion + vertical heat exchange in arc circulation. Nichrome heater (1.2 kW) and externally removable boiler humidifier (2.5 kW stainless armored heater) feed the chamber; condensation drainage at the rear; refrigeration unit in machinery bay.
