(b)Methods of distribution require a steam distributor[s] or Short Absorption
Manifold [s]
(c)Includes stainless steel tank and fill through plastic base to control water stratification by filling at the bottom. Top filling is not acceptable.
(i)Incoloy based resistive heating elements are used to produce steam. Steam production is fully variable from 0 to 100%.
(ii)Control accuracy of up to ±1% using DI/RO water, optional SSR control, and precise humidistat on all models.
(iii)Keypad programming to configure monitor and control humidifier with information messages on alphanumeric LCD display.
(iv)Unit water level is to be continuously monitored with a dual magnetic electronic float system, located outside of the boiling water to ensure
accurate water level control and reduced maintenance. Cool fill water is to be supplied into the sensing chamber to keep the device cool. Systems using conductivity probes or floats located within hot reservoir water are not acceptable.
(v)
(vi)Fill valve check.
