SK300 Major Benefit

• Stainless steel, Teflon coated mass sensing probe

• Water mass is independent of water quality

The unique AFEC® system designed for:

1. maximizing energy efficiency of humidifiers

2. reducing maintenance time and cost

3. Ability to operate with any type of water: 1. Tap water: soft or hard2. DI (de-ionized water), 3. RO (Reverse Osmosis)

AFEC ® (Anti-Foaming Energy Conservation System)
