Description

Tsunami Air-Cooled Aftercooler – 50 CFM – 3/4" NPT – 21999-1250

Part Number: 21999-1250

The Tsunami 21999-1250 Air-Cooled Aftercooler is designed to cool hot compressed air before it reaches downstream dryers, filters, and pneumatic equipment. Rated for up to 50 CFM, this compact wall-mounted aftercooler helps convert water vapor into liquid condensate so it can be efficiently removed from the compressed air system.

By reducing compressed air temperature before the air enters a dryer, the Tsunami Aftercooler decreases the moisture load on downstream air treatment equipment. This helps improve dryer performance, extend equipment life, and reduce moisture-related maintenance and downtime.

With six available wall-mounting configurations, the aftercooler can be installed horizontally or vertically to fit available space while providing approach temperatures ranging from approximately 5°F to 20°F, depending on mounting orientation and airflow clearance.

Key Features

• Maximum airflow up to 50 CFM
• Heavy-duty bar-and-plate heat exchanger
• High-volume fan cooling
• Six wall-mount installation configurations
• Horizontal or vertical mounting capability
• Helps reduce compressed air temperature before downstream dryers
• Condenses water vapor into removable liquid moisture
• Maximum inlet pressure of 290 PSI
• Handles inlet temperatures up to 300°F
• Operates on standard 120 VAC power
• Compact wall-mounted design saves valuable floor space

Benefits

• Reduces moisture load entering refrigerated or desiccant air dryers
• Improves downstream dryer efficiency
• Helps extend dryer and filtration equipment life
• Reduces moisture-related corrosion and contamination
• Helps protect pneumatic tools and production equipment
• Frees up floor space compared with stand-mounted aftercoolers
• Flexible mounting allows installation in tight equipment areas
• Helps improve overall compressed air system reliability

Best For / Typical Applications

• Mobile compressed air systems
• Spray foam equipment
• Mobile paint and finishing systems
• Mobile tire service rigs
• Automotive and body shop compressed air systems
• Industrial compressed air installations
• Systems with high compressor discharge temperatures
• Applications requiring improved moisture removal before an air dryer

Tsunami specifically identifies mobile applications, spray foam, mobile paint equipment, and mobile tire rigs as primary applications for this aftercooler.

Technical Specifications

The manufacturer lists the 21999-1250 with a 3/4" NPT connection, 290 PSI maximum pressure, 300°F maximum temperature, 0.4-amp draw, and 120 VAC electrical supply.

Installation & Performance

The Tsunami Aftercooler can be installed in six different orientations, allowing the installation to be optimized for available space and cooling performance.

• Good: Approximately 15°F–20°F approach temperature
• Better: Approximately 10°F–15°F approach temperature
• Best: Approximately 5°F–10°F approach temperature with unobstructed cooling airflow

Adequate airflow around the heat exchanger is important for achieving the best cooling performance.

Important: Water Separator Required

As the aftercooler lowers compressed air temperature, water vapor condenses into liquid moisture. That liquid must be removed from the air stream.

Tsunami requires a water separator to be installed downstream of the aftercooler.

The recommended matching separator is:

Tsunami Water Separator – Part Number 21999-0131

• 50 CFM
• 1/2" NPT
• 250 PSI maximum pressure
• Automatic float drain

Installing the separator directly downstream allows the condensed moisture created by the aftercooler to be removed before the air reaches your dryer, filters, or pneumatic equipment.

Why Choose the Tsunami Air-Cooled Aftercooler?

The Tsunami 21999-1250 provides an effective way to reduce compressed air temperature and moisture load without taking up valuable floor space. Its flexible wall-mounted design makes it especially useful for mobile equipment, compressor rooms, and installations where conventional floor-mounted aftercoolers are difficult to accommodate.

For systems experiencing high compressor discharge temperatures or excessive moisture, adding an aftercooler ahead of the dryer can significantly improve the performance of the entire compressed air treatment system.

Frequently Asked Questions

What does an air-cooled aftercooler do?

An aftercooler reduces the temperature of hot compressed air leaving the compressor. As the air cools, water vapor condenses into liquid moisture that can then be removed by a downstream water separator.

Do I need a water separator with this aftercooler?

Yes. Tsunami specifies that a water separator should be installed downstream of the aftercooler to remove the condensed liquid moisture.

Can the Tsunami 21999-1250 be mounted vertically?

Yes. The mounting brackets allow multiple horizontal and vertical installation configurations. The mounting orientation and available cooling airflow affect the aftercooler's approach temperature and overall cooling performance.

What size compressor can I use with this aftercooler?

Sizing should be based primarily on the compressor's actual airflow rather than horsepower. The Tsunami 21999-1250 is rated for applications requiring up to 50 CFM.
