TDX Compact | TDX3240 33.59% Eff The Distributor Specialty — Low-Cost, High-Volume, Direct-Glue Convenience

The TDX Compact (TDX3240) is the ultimate high-volume, cost-effective entry point for modern drain water heat recovery (DWHR). Specifically engineered to solve the real-world constraints of tight mechanical layouts, this ultra-low-profile unit delivers a powerful punch in a compact 24-inch frame. It is the premier choice for distributors and high-volume residential builders working on townhomes, multi-family units, and entry-level subdivisions.

By capturing falling-film thermal energy from greywater to pre-heat incoming cold water, the TDX Compact introduces reliable energy-efficiency points to standard builds without breaking the budget. Operating entirely passively, it features zero moving parts, zero electrical requirements, and zero ongoing maintenance.

Intertek Verified Performance Data

• 9.5 LPM / 2.5 GPM Flow Rate: 33.59% Efficiency (6.18 kW / 21,100 BTU/h)

• 7.0 LPM / 1.85 GPM Flow Rate: 38.75% Efficiency (5.11 kW / 17,436 BTU/h)

• 5.5 LPM / 1.45 GPM Flow Rate: 41.83% Efficiency (4.41 kW / 15,047 BTU/h)

Key Technical Advantages

• Direct-Glue ABS Connection: Built with integrated ABS connection hubs, allowing installers to solvent-weld (glue) the unit directly into standard ABS drain stacks using standard cement—completely eliminating the need for separate mechanical couplings.

• Self-Scouring Solid Waste Passage: The central core features completely smooth, continuous interior copper walls with zero internal restrictions or baffles. Standard residential solid waste passes through seamlessly with zero clogging risk.

• Factory-Integrated PEX Ports: Features built-in PEX-ready manifold connections, slashing jobsite installation times by eliminating the need for separate copper-to-PEX transition adapters.

• Highest Performance-per-Inch: Maximizes thermal transfer density over an ultra-short footprint, delivering an impressive 33.59% baseline efficiency where larger units simply won’t fit.

• The Distributor Champion: Compact, lightweight architecture permits ultra-dense palletizing and lower logistics costs, maximizing wholesale inventory efficiency.

• Dual-Wall Safety Integration: Features a fully certified double-wall separation barrier (CSA B55.2) with a vented leak path, ensuring 100% security for the potable water supply.

• Ultra-Low Pressure Drop: The advanced manifold configuration keeps hydraulic resistance minimal, preserving full-volume shower performance even in low-pressure municipal zones.

• Lightweight and Agile: Weighs an ultra-light 9.33 lbs (4.23 kg), turning difficult, tight-space installations into a fast, single-person job.

• Lifetime Material Integrity: Crafted from premium, high-conductivity copper that delivers up to 30 to 50 years of continuous, passive thermal recycling.

Ideal Applications

• High-Density and Multi-Family Residential: Perfect for modern townhome developments and multi-unit projects with restricted vertical plumbing stacks.

• Entry-Level Code Requirements: A seamless, drop-in solution to capture early-tier energy framework targets at the lowest capital cost-per-door.

"Where space is at a premium, performance shouldn't be. The TDX Compact fits into the tightest mechanical stacks, glues directly into the line, and provides a premium, safety-rated upgrade at a price point engineered for high volume."
