Regeneration Energy & TCO Estimator
Estimate the annual regeneration heating load, energy use, and cost for a rotary desiccant dehumidifier — regeneration alone is roughly 39% of total energy and 44% of operating cost. Then see the savings a right-sized system can unlock.

Planning estimate only. This calculator uses a simplified sensible-heating model (air density 1.2 kg/m³, specific heat 1.006 kJ/kg·K) and does not account for desiccant reactivation latent load, purge/cooling sectors, heater efficiency, duct/heat losses, or humidity load — all of which shift the real figure. Industry shares (regen ≈ 39% of energy, ≈ 44% of operating cost) are typical references, not your exact split.
