FAQs

On a hot afternoon, our pre-cooling helps heat exchangers cool down by 30°F (17°C) or more in an arid climate, at least 20°F (11°C) in a temperate climate, and at least 10°F (5.6°C) in a tropical climate.

Heat exchanger pre-cooling consists of cooling the air flowing to the heat exchangers to improve their performance on a hot day. MeeFog systems atomize water to create a fog of liquid water droplets that evaporate and cool the air.

The main difference in fog vs. steam humidification comes down to energy and efficiency. Steam Humidification: requires boiling water, has high energy costs, requires frequent maintenance, and uses chemicals to prevent scale buildup. Fog Humidification: uses high-pressure pumps to create a fine mist, consumes a fraction of the energy, and requires less maintenance. Both methods add moisture to the air, but fog humidification is more cost-effective, energy-efficient, and environmentally sustainable. For facilities seeking to replace steam humidifiers, fog systems offer equal performance at a much lower operating cost.

Fog humidification is ideal for buildings aiming for energy efficiency and sustainability. Because it doesn’t rely on boiling water, but instead uses a low-grade heat source like hot water loops directly in the air handler or warm return air, it dramatically reduces carbon emissions, utility bills, and maintenance costs. Whether in data centers, museums, hospitals, or manufacturing facilities, customers report measurable energy savings in humidification while maintaining precise humidity levels.

The cost of humidification systems depends on installation size and application. While a MeeFog system has a similar initial investment as a steam humidifier, the operating cost is dramatically lower. Over its lifetime, a fog system typically costs 50–70% [Ask Elliot to confirm this number] less to run and maintain than steam. This makes MeeFog one of the most affordable long-term humidification solutions on the market.

When it comes to energy savings humidification, MeeFog delivers a major advantage. Steam systems require large amounts of electricity or natural gas to boil water. In contrast, fog systems only need a small high-pressure pump paired with a low-grade heat source such as a hot water loop inside the air handler. This design avoids boiling water entirely, and  matched with a waste heat source , the only added energy load is a small horsepower motor for the pump. On average, MeeFog uses one percent of the energy of steam humidification, leading to 50–80% lower utility bills. Many customers recover their investment in just 1–3 years through energy savings alone. Fog systems also provide free cooling and there is no condensation in duct sections downstream of the fog system.
