HFQTZSSL AC Receiver Drier with Switch for Thermo King Tripac Evolution – Direct Fit, Stainless Filter

HFQTZSSL 61-6630 is a direct-replacement AC receiver drier with built-in switch engineered to restore reliable refrigerant filtration and moisture removal in Thermo King Tripac and Tri-Pac Evolution APUs.

This receiver drier (part numbers 61-6630, 616630, 8033115) is designed to meet OEM specifications for Thermo King Tripac and Tripac Evolution auxiliary power units. It removes moisture and debris from the air conditioning refrigerant, protects downstream components such as expansion valves and compressors, and includes a service switch for system diagnostics or pressure monitoring. Replacing a worn drier helps maintain cooling performance and reduces the risk of contamination-related failures.

How does this receiver drier protect my Thermo King Tripac system?

The HFQTZSSL drier traps metal particles and absorbs moisture before refrigerant reaches sensitive components. Its internal stainless steel filtration media captures contaminants that can damage expansion valves and compressors, while desiccant material binds water to prevent ice formation and corrosion.

• Stainless steel filter screens out metal shavings and debris.
• High-capacity desiccant removes moisture to guard against valve icing.
• OEM-style fit ensures correct routing and connection to existing lines.

Will this part fit my Thermo King Tripac or Tri-Pac Evolution APU?

This receiver drier is intended as a direct fit for Thermo King Tripac and Tripac Evolution units that use part numbers 61-6630, 616630, or 8033115. Always confirm your OEM part number before ordering to ensure compatibility and avoid unnecessary returns.

• Direct replacement for Thermo King 61-6630 / 616630 / 8033115.
• Designed to OEM dimensions and port locations for straightforward swap-in.
• Compatible with the common Tripac and Tri-Pac Evolution APU models listed by Thermo King.

What are the practical benefits of replacing the receiver drier now?

Replacing a degraded drier restores filtration and moisture control, improving cooling stability and extending the life of compressors and valves. Routine replacement during major A/C service reduces the chance of costly breakdowns and helps maintain factory performance.

• Prevents moisture-related expansion valve icing and system blockages.
• Reduces wear on compressor and other moving parts by removing contaminants.
• Simplifies maintenance by using a readily available OEM-equivalent unit.

How do I install and service this replacement receiver drier?

Installation is typically performed during A/C system service — evacuate refrigerant, remove the old drier, and install the new unit following Thermo King torque and line-cleaning procedures. The built-in switch provides a convenient connection point for diagnostics or pressure sensors during reassembly.

• Evacuate and recover refrigerant per environmental regulations before removal.
• Replace with same orientation and secure fittings to OEM torque specs.
• Use vacuum and leak-check procedures after installation before recharging.

Who is this for: technicians, fleet maintenance managers, and owner-operators who service Thermo King Tripac and Tri-Pac Evolution APUs and need a dependable OEM-matching receiver drier with switch. If your APU shows reduced cooling, intermittent valve freeze-ups, or the unit has reached recommended service intervals, this HFQTZSSL 61-6630 replacement helps restore proper refrigerant filtration and moisture control so the system runs more reliably between services.
