MTC-A Evaporative Condenser

• EVAPCO’s MTC-A is the first evaporative condenser in the industry to feature composite fibreglass panels formed entirely by an advanced, environmentally friendly, LRTM closed mould manufacturing process.
• The concept and design basis of the MTC-A stems from EVAPCO Australia’s proven MEC product line, having 20 years of installed history.
• All aspect of the MTC-A, from concept to design to manufacture are performed “in-house” and by EVAPCO.
• The final assembly of fabricated and globally sourced components is completed at one of EVAPCO’s facilities.
• Country of origin for the final assembled products is available from Australia, Belgium, Italy or South Africa.

The refrigerant gas is discharged from the compressor into the inlet connection of the MTC-A condenser. Water from the condenser’s sump is circulated over the condenser coil, while ambient air is simultaneously drawn into the unit. As the ambient air moves up through the coil section, a portion of the spray water is evaporated into the air stream. The evaporative process cools the spray water, which in turn cools the tubes containing the refrigerant gas. The cool tube walls cause the compressed refrigerant gas to give up heat and condense into liquid. The condensed liquid flows out of the coil to the high pressure liquid receiver for return to the system. The hot, saturated air is drawn through the drift eliminators, where any entrained water droplets are removed. The condenser’s fan then discharges this air stream out of the top of the unit at a high velocity, where it can dissipate harmlessly into the atmosphere. The water which was not evaporated falls into the sump and is recirculated by the spray pump to the water distribution system above the condensing coil section.

Thermal-Pak II Coil

EVAPCO's Thermal-Pak II coils patented design assures maximum cooling capacity. The airflow through the coil is counterflow to the fluid flow, providing the most efficient heat transfer process. A special coil design is utilised to reduce the air pressure drop through the unit while maximising tube surface area and increasing its heat transfer capabilities.

• Elliptical return bends allows for more circuits per coil bundle increasing the maximum capacity per footprint
• Coil located in airstream increasing dry bulb switchover temperature
• CrossCool Internal Tube Enhancement increase fluid turbulence providing additional evaporative capacity

Drift Eliminators

• Limits the drift rate to less than 0.001% of the recirculating water rate
• Limit the potential of spreading Legionella
• Constructed of an inert polyvinyl chloride (PVC)

Superior Air Inlet Louver and Screen Design

• Constructed of an inert polyvinyl chloride (PVC)
• Two pass design that minimizes splash-out and the potential for algae formation inside the tower
• Framed in steel in easily removable sections

Pressurised Water Distribution System

EVAPCO's Zero Maintenance ZMII® spray nozzle remains clog free while providing even and constant water distribution, providing the industry's best performing non-corrosive, maintenance-free water distribution system.

• ZMII spray nozzles have a 1-1/4" diameter opening and a 1-1/4" splash plate clearance
• Mounted in corrosion-free PVC water distribution pipes that have threaded end caps
• Provides unequaled coil coverage and scale prevention
