Electric power steam humidifiers



Canada Blower is proud to introduce the most advanced Commercial Humidifiers in today's market:


electric steam humidifier SK300

General Description:

  • The SK300 are power humidifiers designed to provide dry sterile steam for humidification. 
  • They combine the latest microprocessor based electronic design with carefully matched metallurgical and mechanical technology perfected over two decades.  The design is based on permanent rather than replaceable containers.

Simplicity of Operation and Service:

  • The SK300 humidifier consists of an automatically water fed stainless steel container with an easily removable cover containing heating elements and water level sensors. 
  • Periodic servicing of the unit can be easily done in minutes.  All mechanical, power and control connections arereadily accessible for quick servicing.
  • The mechanical and electrical compartments are secured by wide hinged doors allowing comfortable inspection and access to all components.

Exceptional Reliability:

  • Reliability of the SK300 humidifier is one of the features that set it apart from competing humidifiers.  Using the proprietary AFEC technology, the SK300 is much more forgiving to variable water conditions.  Great care has been taken to select materials which have proven themselves for their exceptional performance in very harsh conditions.  Such materials are elements made of super alloy, incoloy 825, teflon sleeved stainless steel level control probe, silicon tubing and baked enamel painted aluminum cabinet.
  • Selection of electro-mechanical and electronic components has been based on many years of experience and exhaustive testing.  All SK300 units pass through rigorous Q.C. inspection and full power check. 


  • Permanent, easily serviceable stainless steel container
  • ON-OFF or MODULATING control functions
  • Interactive LCD display and microprocessor controlled self-diagnostics
  • AFEC technology provides greatest energy conservation and safest operation
  • Functions exceptionally well in severe, normal or D.I. water conditions
  • Self-cleaning heating elements
  • Unit is built from the most advanced materials such as stainless steel and teflon components and silicone hoses

Aluminum housing and the best electronic and electro-mechanical parts.

electrode steam humidifier Multi-Steam: For the most efficient steam absorption, N.E.P. developed 3 different steam dispersion methods using the MULTI-STEAM, SAM or REGULAR distributors.

blowing humidifierS.D.U. (Space Distribution Unit):

Our lower profile Steam Distribution Unit is to be used where a ducted air distribution system is not available.  The steam is discharged directly into the required area.   S.D.U. is available in two sizes.  A tangential fan delivers a quiet and efficient  steam distribution.

Anti-Foaming Energy Conservation System:

The AFEC technology developed by the N.E.P. engineering team offers a unique safety and energy conservation management of expensive boiling water and steam.  The AFEC system is made of a mass measuring water sensor, anti-foam sensor, electronic high temperature sensor, interactive LCD display and microprocessor controller. 

The AFEC system is unique because: 

The water sensor cannot be falsely triggered by foam formation on the top of the boiling water.  This eliminates the problem of heating elements burning out in free air. 

The additional foam-sensing probe, which is unique to our design, would automatically initiate a drain cycle upon foam formation.  Unlike other humidifiers, the drain can be initiated only when necessary without having continuous skimming to drain expensive boiling water.  This is an excellent energy conservation measure. 

The SK300 is unique in having fast actin electronic safety temperature sensors inside the steam container in very close proximity to the heating elements.  Other humidifiers use only a bimetallic external electro-mechanical temperature switch (which is also standard on all SK300s).  Therefore, the AFEC system provides an additional layer of protection. 

Direct-fired units utilize air that will be sent to the heated space for combustion without use of a heat exchanger. The products of combustion are mixed directly with large volumes of outdoor air. Such mixing is considered safe because of the high dilution ratio.

Buffalo Blower Co. have completed a major re-design of its line of industrial air makeup units for building ventilation. In industrial plants where there is a high density of employees and many manual operations involved, an improvement in the environment can produce substantial benefits in terms of increased production, reduced errors, and a decline in complaints and absenteeism among employees.

A Direct Gas-Fired Air-Handling Unit AHU may be used as a primary or secondary source to heat a building space. When used for this application, a room thermostat controls unit outlet air temperature.

On a call for heat, a space-heating unit will provide air at the desired room temperature. An airhandler may also be designed to increase outlet temperature when room temperature is low. A duct stat or probe at the outlet of the unit prevents outlet temperatures from exceeding the maximum allowable value.

When a unit blower runs continuously, room air is monitored and the outlet air temperature is modulated to maintain the temperature.

Systems are usually designed for either Space Heating or for Make-Up Air use. However, standard Make-up Air Units may be provided with a room thermostat that monitors indoor minimum set point, a signal is sent to the unit to override outlet temperature set point and turn the unit to full fire. When minimum room temperature is satisfied, unit returns to outlet air temperature control mode.

Return Air Units are a design that includes a damper to bring room air back into the unit. These re-circulate indoor air through a unit with a minimum of outside air added. This type of unit is able to provide air movement for indoor comfort and reduced temperature stratification, but with a minimum of heat added to the building.

Return Air Units are widely used for direct fire space heating applications. They can be supplied with a maximum 80% return / 20% fresh air, per ANSI standards. Other options include a 50/50 arrangement. “80/20” Units are configured to modulate from the 80% return/20% fresh air to up to 100% outside or fresh air. 50/50 units are generally designed to switch from 50% return / 50% fresh to 100% fresh, with no modulation between.

In addition, thorough burning of the natural gas takes place so that no harmful products of combustion enter the airstream. One product of combustion is water vapor, which can be problematic with very tight building construction due to the potential for condensation in colder climates. For tight buildings, it is best to consider the use of indirect-fired equipment. There are several common configurations of direct-fired units.

All return air should be brought in downstream of the burner and not recirculated through the burner. This is to prevent buildup of waste products from the combustion process within the building. It also prevents contaminants originating within the building environment from being passed through the direct fire burners. The combustion of unknown contaminants can be a serious Safety or Indoor Air Quality problem, and so must be avoided.
