Extend the comfort season of your sunroom without an HVAC system!

Even if the building code says that you cannot heat or cool a sunroom, you can ventilate it. Employing an HVAC system to condition the air in the sunroom would increase its year ‘round comfort to a level where it could be considered a normal living space. As such, it would have to comply with all of the other building codes including a limited amount of glass. But exhaust fan can use the temperature differential between the inside and the outside to greatly improve the conditions in the space and "lengthen" the season.

The TC1000-T, the only American made ventilation system designed for sunspaces, is designed for clean, simple, standardized installation.  It is engineered to slip into all of the major sunspace manufacturers glazing systems.  The remarkably versatile TC1000-H fits in flat roof, solid roof and sidewall applications for whole house cooling where interior attic installation is impossible.

When the TC1000 is turned on, the lifting motor pushes the unique, internal, insulated damper up out of the way, and two super quiet fans begin positively venting the space. The fan features a motorized and insulated closure system which pulls down tightly over the fan openings when it is turned off , preventing cold air, rain, snow and insects from entering .  A positive seal of 1/2 inch of foam covers the fan openings, blocking drafts and preventing heat loss. The positive, powered ventilation moves up to 800 cubic feet of air per minute.  The internal thermostat, factory set to approximately 90ºF, allows for automatic, high/low speed control. When the temperature in the room rises to this point, the fans will automatically shift speed from low to high.

No other fan system gives you as tight a seal, as much insulation and as much control as the TC1000.
