The TrilliumSeries Condenser
The TrilliumSeries Condenser uses a patented Dry-Coil Adiabatic Design that saves
energy, reduces refrigerant charge, and lowers operating costs. With the use of proprietary
logic and sophisticated controls, the On-Demand Adiabatic Pre-Cooler uses water only
on the hottest days to maintain condensing temperatures that typical air cooled technology
can’t achieve.

Notes for the TrilliumSeries Condenser Payback Chart:
1. California Title 24 pricing equation for air cooled condensers.
2. California Title 24 2013, effective on 1-1-2014, states all condensers must have VFDs to control fan motors.
3. Condensing temperature for air cooled is set at 100-110°F depending on the climate; TrilliumSeries Condenser is set at 95°F.
4. In Phoenix and Los Angeles, the first cost of a TrilliumSeries Condenser is lower than the first cost of an air cooled condenser.
5. The cities were selected based on climate conditions.

Modes of Operation
››
Dry Mode
The ambient air at the dry bulb temperature passes through
the pads and then over the microchannels. The ambient air
condenses the refrigerant in the microchannel coils which is
then returned to the evaporators.

On days when the load is high and the ambient air
temperature is high the unit will run in On-Demand
Adiabatic Pre-Cooler Mode. Water is evenly sprayed over
highly efficient cooling pads. As the air passes through
the pads, water is evaporated in to the air, and the air is
humidified, cooling temperatures down to 2-3 ºF above
wet-bulb temperature. Such substantial depression of the dry
bulb temperature results in a major increase in dry cooling
capacity.

The cooler air passes over the microchannel and condenses
the refrigerant in the microchannel which is then returned to
the compressor. In the sump there is an industrial duty pump
that recirculates the water. The EcoFlex Controls determine
when the water is purged from the sump. Part of the
distributed water is evaporated, while the excess water assists
in rinsing the pad to keep it free from debris and minerals that
would otherwise stay behind on the pad after evaporation.

Rebate Map
Potential rebates are available for decreased energy use. These opportunities are highlighted
in blue on the map above. As illustrated, a majority of states offer utility incentives and rebates
which further decrease the initial investment of the TrilliumSeries Condenser.
There are various types of rebates available for energy savings and are dependent on utility regulations.

• Variable Frequency Drives: $80/HP
• Refrigeration Controls: $75-$100/Controller
The above are examples based on information from dsireusa.org. Dsireusa.org is a website with information on state,
local, utility, and federal incentives and policies that promote renewable energy and energy efficiency. Established in
1995 and funded by the U.S. Department of Energy, DSIRE is an ongoing project of the N.C. Solar Center and the
Interstate Renewable Energy Council.
For custom rebates, an analysis of the overall system energy savings from air-cooled to the TrilliumSeries Condenser
maybe necessary. This analysis is available from Baltimore Aircoil Company along with any application support.
