No More Holes for Exhaust Ducting with the ET.COMPANION

When installed with an EVAPORATIVE TANKTM,the ET- Companion Condenser TM removes water from the evaporator's air exhaust. The dry air is returned to the EVAPORATIVE TANK TM to work again.

B E N E F I T S • No more holes in your roof for exhaust ducting. No

need for permits from the air quality people: this is a completely closed-loop air system.

• Recovers all water that is evaporated. Today's regula- tions require recovery of resources wherever possi- ble. It makes economic sense, and removes the need for permits. Reuse your rinse water.

• Eliminates the air make-up problem. The same air is used over and over again. No need to heat or air con- dition replacement air - saving thousands of dollars.
