ot summer air usually has high humidity, and a person's ability to throw off
heat by evaporation decreases or stops altogether.  Cooling is needed then to
provide comfort by extracting excessive moisture from the air - de-humidification
process.

During the winter, the condition is reversed. Cold outside air, heated to
room temperature, has great ability to hold extra moisture.  For example,
air at 70 F can hold about 20 times as much asair at 0 F. Heated wintertime air
takes moisture from whatever sources are available, including the human body.

If the air in your home does not contain enough moisture, you may feel cold and
uncomfortable - even at 75 F.  Dry, thirsty air evaporates moisture from your
skin, acooling process that mkes you feel chilly. But, with humidity raised to
recommended levels, you can dial you thermostatdown to 68 F and still feel
comfortable.

A 10% change in the relative humidity will feel like a 1 degree Fahrenheit
change in room temperature. This effect is due to the nature of the human bodies
cooling system. When we are too warm, we sweat, providing moisture that can be
evaporated by the air, thus cooling us down. When the humidity is too low, the d
ry air will pull moisture from the skin, causing you to feel cooler.

Most people believe that bacteria grows and reproduces best in humid and warm
environments. This is only partially true. Many bacteria, such as pneumococcus,
staphylococcus, and streptococcus survive much better in very humid environments
(above 70% relative humidity) AND in very love humidity environments (below 20%
relative humidity). In fact, these bacteria die 20 times faster environments
where the humidity is between 45% and 55% (normal range in a properly humidified
home) than they do in locations where the humidity is about 70% or below 20%.

A leading manufacturer of thermostats and humidistats recently surveyed 1,000
households across the United States about their indoor air quality in the fall
and winter. An astounding 70% of respondents complained of air so low in humidity
 that is caused symptoms such as dry and flakey skin, itchiness, sore throats,
and bleeding noses from cracked nasal membranes. More than 75% complained of
feeling too hot or too cold even though their thermostats said the home was at a
temperature that they normally found comfortable.

"Relative humidity in habitable spaces preferably should be maintained between 30% and 60% relative
 humidity...to minimize growth of allergenic or pathogenic organisms".

This statement suggests that the humidity level in the occupied space be controlled so that it is
above 30 percent relative humidity. As a result, some building designers specify humidification
control systems to maintain space humidity above 30 percent during occupied hours.


Are steam humidifiers required? No. Steam humidifiers are suggested for space humidification.

"Steam is preferred as a moisture source for humidifiers...".

Electric Duct Heaters

Let Canada Blower take you to a higher standard of heating technology with our innovative “commercial” and “industrial” electric duct heater. Our experienced team includes qualified welders, electrical specialists, sheet metal workers and other qualified personnel that have brought their talents together in order to produce the best innovative and “Custom Built” electric duct heater.

CBC electric heaters have sensational features that make them the best in the industry. Our "Patent" HEC universal controller can operate without external inputs to provide maximum heat for variable air velocity and temperature conditions. Sensors are located close to the heating elements. The patent pending controller considers only convection heat and differential temperature to precisely measure air velocity and continuously update the proportional control signal to the heater. The result is an extremely precise control of heater output in different environments including VAV applications.

NCBC supplies heaters up to 1000 kW with up to 40 kW per sq.ft. to suit any application. Our heaters are approved for zero clearance to combustible materials and are safety tested and listed by “Underwriters Laboratories” (UL) and the “Canadian Standards Agency (CSA), and meet the requirements of the "National Electric Code".

A variety of features are available to design the perfect and ideal heater which will satisfy your needs at "Competitive Pricing".
Open Coil (grade A and C), Standard Tubular and Finned Tubular elements.
Slip-In, Flanged and Round Collar mounting.
