Aspen dm36e3d-177l-600 Evaporator Coil 3 Ton R-32

Product Description

The ASPEN dm36e3d-177l-600 is an uncased evaporator coil engineered for manufactured housing applications running R-32 refrigerant. Rated at 3 nominal tons, it features rifled aluminum tubing and enhanced aluminum fins for efficient heat transfer. The coil accepts left- or right-hand refrigerant and plumbing connections and ships nitrogen-pressurized after multi-stage leak testing — including high-pressure testing at 500 psi and mass spectrometer pressure decay with helium. A liquid line Schrader valve is included for field pressurization-confirmation testing. Licensed HVAC technicians install this coil as part of a split-system cooling or heat pump setup in HUD-code manufactured homes.

The dm36e3d-177l-600 is rated for upflow and downflow orientations, making it adaptable to a range of manufactured housing air handler configurations. Upflow and downflow plates plus a manufactured housing drain hose are included in the box. The coil is ETL listed for use with R-410A, R-454B, R-22, and R-32 when the proper metering device is installed. The factory-installed metering device is an R-32 NB TXV, so verify system refrigerant and TXV compatibility before installation. Heavy-duty polypropylene drain pans are included to meet manufactured housing drainage requirements.

Key Features

• Rifled aluminum tubing and enhanced aluminum fins for improved heat transfer efficiency
• Multi-stage leak testing: 500 psi high-pressure test, helium mass spectrometer pressure decay, then nitrogen-pressurized and sealed for shipment
• Left- or right-hand refrigerant and plumbing connections for flexible installation
• Liquid line Schrader valve for field pressurization-confirmation testing
• ETL listed for R-410A, R-454B, R-22, and R-32 with proper metering device
• Heavy-duty polypropylene drain pan with manufactured housing drain hose included
• Ten-year limited warranty

Compatibility

ETL listed for use with R-410A, R-454B, R-22, and R-32 refrigerants when the proper metering device is used. Factory-installed metering device is an R-32 NB TXV. Designed as an uncased upflow/downflow replacement or new-installation evaporator coil for HUD-code manufactured housing split systems at 3 nominal tons.

Installation Notes

Installation must be performed by a licensed HVAC technician holding the appropriate EPA Section 608 refrigerant handling certification. Shut down and de-energize the air handler and disconnect power at the breaker before beginning coil work. Verify the metering device, refrigerant type, and system tonnage match before connecting refrigerant lines. Follow applicable local mechanical codes and manufacturer torque and brazing procedures for all refrigerant line connections.
