Electro-thermal humidifier (SR series)
Electro-thermal humidifier (SR series)
Category:
Detail
Application：
Individually work for all kinds of working sites, such as pharmaceutical factories, operating rooms and food fields; cooperate with central air conditioner (AC) and fresh air units
Product features：
◇High applicability, linear regulation
◇Safety, reliability, integrated structure, convenient installation; Suitable for all kinds of water
◇Automatic control
◇Cleanness
◇0-10V signal automatic control
Working principle：
Electro-thermal humidifier is based on the principle of resistance heating, namely after electro-thermal pipe is dipped into water and electrified, the pipe will generate heat according to Joule's Law so as to raise the water temperature and produce steam. Electro-thermal humidifying controls the output of steam by regulating the heating power of heating units.
Working conditions：
Environment temperature & humidity: Ambient temperature of electro-thermal humidifier: 0-40℃ humidity: <80%RH
Feed water quality: Clean tap water, de-mineralized water, de-ionized water, etc
Water hardness: < 30 German degree
Intake pressure: 0.1-0.3Mpa
Duct pressure: ≤100mmH2O
Model Description：
Electric Cabinet Description：
SRA type electro-thermal humidifier requires electric cabinet.
Because the main frames and electric cabinets of SRC-II and SRD type electro-thermal humidifiers adopt integrated design, the two humidifiers need no additional electric cabinets.

Note: We manufacture those electric humidifiers whose single steam output is more than 80Kg/h in accordance with non-standard specifications. For more, contact us please.
Control System：
To meet different requirements, our company has designed and developed various kinds of control modes：
1. N type control mode：
Humidifying control：ON/OFF
Outside humidity controller only can control the humidity by ON/OFF switch；
2. K type control mode
Humidifying control: regulate proportionally
Outside humidity controller con regulate the humidifying rate by 0-10V/4-20mA regulating signal.
Accessories：
Aluminium steam distribution pipe：
Function: The steam produced by electro-thermal humidifier is evenly ejected into AC chamber or narrow air duct.
Quick steam distributor：
Function: The steam produced by electro-thermal humidifier is evenly ejected into AC chamber or narrow air duct while steam diffusing within short distance.
Note: There is steam absorption distance problem for electro-thermal humidifier. Unsuitable steam absorption distance can lead to condensation troubles for medium-and high-efficient strainers, fans and ducts.
Indoor steam distributor：
Function: Steam produced by electro-thermal humidifier diffuses quickly and evenly indoors through special fans.
