Air humidifier, MHDM-3S series

MHDM series are steam duct humidifiers

This type of humidifier boils water to produce hot steam, which is fed into the airflow created by the fan. Hot steam kills bacteria and mold. But there is a potential risk of burns during its operation.

1 ... 3 kg/h

Capacity:

Quick detachable steam cylinder

Parameters:

The humidifier of MHDM series is used with small units, such as fan terminals or small fresh air supply units, where a small steam humidifier is required. It is particularly suitable for under-ceiling installation or other applications with a suspended ventilation system
Compact design, only 260 mm high, allows installation in confined spaces under the ceiling
The humidifier is easy to attach

Control circuit board

The cylinder can be easily replaced
Multiple safety systems
The unit comes with a steam hose and a steam distribution tube

Applications:

Computer rooms
Household air conditioning systems
Laboratories
Surgeries
Electronics factories
Hospitals
Private houses
Hotels
Offices

Relative Humidity Influence on Human Health

Sterling and Arundel showed in their key study done in 1986 that the optimal conditions for human health are 40-60% RH at normal room temperatures.
HVAC professionals still use this research as the main source for setting the standards for a healthy environment set by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE).
First of all, maintaining a relative humidity within 40-60% range prevents dryness of the skin and mucous membranes of the eyes, nose, etc. Also the impact of viruses, bacteria, and allergens found in the environment is reduced in this range of RH, as we can see in the graph below.

Optimum relative humidity range for a healthy environment

Health Protection

Maintaining healthy humidity levels in homes, offices, hospitals, clinics, and other healthcare facilities will reduce the spread of viruses. This will create additional protection for staff and patients during the COVID-19 pandemic.
It is very important to maintain a relative humidity level in 40...60% range in order to:

Reduce in most viral activity
Protect our body's natural barriers from drying out
Provide self-cleansing of the respiratory tract, helping our innate antiviral protection

Features of using steam duct humidifier

Сonnection to the central water supply system
Hight temperature steam kills the most types of germs, bacteria and mold
Fully automated operation without user participation
Automated water refreshing to reduce salts concentration
Does not cool the air supplied to the room

Accessories:

Duct humidistat

Sensors / switches of DXH series are designed to
measure relative humidity in ducts with an integrated
self-calibrating and maintenance-free digital
sensor. Four pre-defined ranges along with one
one user-definable range allow setting up an ideal
measurement window. The units have an analog
output and a relay output along with a Modbus RTU
(RS485) communication port.

Key features :

Microcontroller-based design
1 analog output and 1 relay output
Modbus RTU (RS485) communication port

Differential pressure switch

These sensors are high-precision adjustable
differential pressure switches that allow monitoring
overpressure, underpressure and differential

pressure of air or other non-combustible, non-
corrosive gases. The setpoint can be adjusted using

a calibrated scaled knob for the switching pressure,
or using a screwdriver and a pressure gauge for the
switching ΔP.

Key features:

High precision sensitivity
Available versions for a variety of pressure ranges
Adjustable switching setpoint (DP)
