CUTTING THE COST OF OWNERSHIP

NesbittAire understands the environment. We also understand that maintenance in the classroom is a different ballgame. That's why we developed and patented features that make our unit ventilator the lowest cost to own unit on the market. Most unit ventilators are not maintenance friendly. Replacement of a defective motor or coil can be time consuming. In the world of onsite maintenance time equals money.In a standard unit ventilator repair of a motor or coil must be completed when the classroom is empty, which usually means after hours or weekends. It means tearing the unit down repairing it on site. In the case of coil replacement or upgrade it can mean actual change to the chassis in our competitor's product.

NesbittAire understands school budgets are tight so we've addressed and solved those problems through incorporation of two patented features:

1. "Unicoil" - We have developed the only modular coil subassembly in the unit ventilator marketplace. In the unlikely event of a coil failure, the entire coil subassembly can be exchanged in a matter of minutes. It simply involves removing the input and return "sweat connections", taking out four securing screws, and sliding the coil out. The new coil is installed the same way.

Failure of a NesbittAire coil is an unlikely event however since we use a blow-through design. Our design keeps the coil away from the outside air stream and mixes warmer return air with the fresh air before hitting the coil.

Perhaps the best feature of the "unicoil" is that it provides a true future cooling option. If the school has a NesbittAire unit ventilator with heat only and wants to upgrade it to include cooling, the coil subassembly is the only thing that needs to be changed. If the new coil configurations adds sufficient static pressure to require a larger motor, that is taken care of by our modular motor board discussed next.

2. Modular Motor Board. - We have spent hundreds of hours of design and test time on our modular motor board. Replacement of a motor can be done in the classroom in less than ten minutes. It simply requires loosening four securing bolts and unplugging a single connector, the entire motor assembly slides out and can be replaced in minutes. The unit can then be taken to a repair shop for repair at the maintenance engineer's convenience.

Our motor board is also the quietest in the industry. In a "head to head" test with the advertised quietest supplier at an independent test lab, NesbittAire was awarded a large job on the East Coast based on sound data. That eliminates the argument that a unit ventilator must use a draw-through design and risk coil freeze-up to be quiet.

3. We also have a third patent pending on our modular self-contained condenser unit and heat pump. The entire chassis can be removed from the classroom by unplugging two connectors and sliding it out of the room cabinet to be repaired out of the classroom. In the larger units having dual modules, the unit can remain operable in a reduced capacity mode, supplying a level of classroom comfort until repaired the unit can be returned.

It has been said for many years that "John Nesbitt wrote the book on classroom comfort". In the continuation of his innovation, NesbittAire has addressed the nation's school budget issues by making a maintenance friendly unit ventilator that meets or exceeds airflow and sound specifications.

We are continuing a "tradition of innovation."
