General Questions

The Evapco ATC-1655E is a high-capacity, induced-draft, counterflow evaporative condenser designed for industrial refrigeration, HVAC, and process cooling applications. It efficiently removes heat from ammonia and other refrigerants to improve system performance.

An evaporative condenser uses a combination of air and water to cool refrigerant vapor. The refrigerant travels through the Thermal-Pak II® Coil, where heat is transferred to the water. As the water evaporates, it removes heat, condensing the refrigerant back into a liquid state.

    The ATC-1655E is widely used in:
  • Ammonia refrigeration systems (food processing, cold storage)
  • HVAC applications (commercial & industrial cooling)
  • Chemical & pharmaceutical plants
  • Data centers requiring high-efficiency cooling solutions

Technical & Performance Questions

The Evapco ATC-1655E has a nominal capacity of 1655 TR per full package and 1175 TR for ammonia (R-717). When purchased as a single unit, the capacity is 828 TR (nominal) or 588 TR (ammonia).

The ATC-1655E is optimized for ammonia (R-717) but can also be used with other industrial refrigerants such as R-22 and R-134a.

This model includes Power-Band Belt Drive Systems and Totally Enclosed Fan Motors (TEAO) for reduced power consumption and quiet operation. It also has a low refrigerant charge, which helps maintain efficiency and cost savings.

Installation & Operation Questions

    Installation includes:
  1. Setting the unit on a level, structural steel support frame.
  2. Connecting refrigerant piping to the coil.
  3. Installing water and electrical connections.
  4. Verifying proper airflow and pump operation.
  5. Testing the system before full operation.

The ATC-1655E requires a minimum clearance for proper airflow, with an overall length of 36' 2-1/2” and a height of 16' 10-7/8”.

  • Ensure proper water levels in the basin.
  • Start the spray pump before running fans.
  • Gradually bring the unit up to operating temperature.
  • Monitor drift eliminators and air intake louvers for blockages.
  • Perform routine maintenance for optimal performance.

Maintenance & Longevity Questions

  • Monthly: Check drift eliminators, spray nozzles, and pumps.
  • Quarterly: Inspect the coil and water basin.
  • Annually: Perform a full system check and clean the unit.

A non-chemical water treatment system is optional and recommended to reduce scaling, corrosion, and bacteria growth.

Buying & Cost Considerations

  • Cost savings of up to 50% compared to new units.
  • Immediate availability vs. long lead times for new equipment.
  • Fully inspected & tested by Genemco to ensure performance.

  • Large inventory ready to ship worldwide.
  • Thorough inspections & testing before delivery.
  • Expert guidance to find the right unit for your needs.

Evapco ATC vs. Other Evapco Models

The ATC-1655E is designed for high-capacity applications and features a counterflow design for maximum efficiency. Compared to other models, it offers larger cooling capacity, better water distribution, and optimized heat transfer performance.

  • The ATC-1655E is a counterflow condenser, whereas the ATWB series features a closed-circuit cooling system that may be better suited for water-saving applications.
  • The PMC series is a forced draft evaporative condenser, whereas the ATC-1655E is induced draft, which offers quieter operation and better air circulation.

  • Newer drift eliminator technology reduces water loss.
  • More efficient fan motors reduce power consumption.
  • Improved corrosion resistance extends equipment lifespan.

Ammonia Refrigeration & Role in Systems

It is used to condense ammonia gas from compressors back into a liquid state. This is a crucial step in the heat rejection process of industrial refrigeration systems.

Yes, it meets IBC seismic compliance, ASHRAE, and CTI certification standards, ensuring reliability and durability in industrial applications.
