Desiccant dehumidification: energy savings calculator

Compares your current desiccant dehumidifier with the WaHa Vaporator® at the same duty, for the four markets where desiccant dehumidification is used. Enter your own conditions and your own equipment's energy figure. WaHa figures are the unit's design specification at the stated condition.

Units
Process air entering the dehumidifier
Your current dehumidifier
Enter your own equipment's figure at this condition (kg of water per kWh; the kWh per kg equivalent is shown above). The default is a reference figure for legacy silica gel equipment at the market's typical condition.
Economics and site factors
Region presets are approximate defaults; edit them for your site. Carbon price is applied only if you enter one (compliance cost, internal price, or offset cost).
–lower dehumidification energy
–your equipment, kg of water per kWh
–WaHa Vaporator®, kg of water per kWh
–operating cost saved per year

WaHa Vaporator® outlet air (design values)

Outlet temperature equals inlet temperature: the heat released by drying is recovered inside the unit. Leaving relative humidity is available down to 10%.

Reference conditions across the three standalone markets

Baseline figures are reference values for legacy silica gel equipment and should be replaced with your own. Savings are direct machine energy for the same water removed; heat-recovery and cooling-side benefits are not included.

WaHa Vaporator® figures are the unit's design specification at the stated inlet condition. All figures are design-point energy factors (kg of water removed per kWh at the stated condition, with kWh per kg in parentheses), not integrated energy factors weighted over an operating profile, and will vary by site and equipment. Baseline figures for other equipment are reference values; enter your own. The low dew point line model uses the customer's own chiller, silica gel, and zeolite figures.
