B3-22 Parallel Flow Condenser for TCH12A Bus AC, Universal Left & Right Side

The B3-22 universal left-right parallel flow condenser is a standard heat dissipation core customized for TCH12A rooftop air conditioning units, widely equipped on 12-meter long-distance intercity coaches, tourist buses and large city transit buses. The unique reversible mounting design allows one condenser to replace both left and right original units, greatly simplifying spare parts management for bus fleets and repair workshops.

As the core heat rejection component of the refrigeration system, it transfers high-temperature heat from compressed refrigerant to outside air, its micro-channel parallel flow design ensures stable high cooling performance for large-volume passenger cabins under high ambient temperature.

Core Product Advantages

1. Universal Left & Right Reversible Mounting Design

   Symmetrical layout of mounting lugs and pipeline interfaces, compatible with both left-side and right-side installation positions of TCH12A AC units. Only one spare part model is needed instead of two separate left/right versions, cutting inventory types and capital occupation.

2. Integral Vacuum Brazed All-Aluminum Micro-Channel Structure

   One-time vacuum brazing integral molding eliminates weak solder joints, micro flat tubes form dense heat exchange network. Heat transfer efficiency is significantly higher than traditional copper tube condensers, effectively lowering system working pressure and avoiding high-temperature protection shutdown.

3. Strong Anti-Vibration & Anti-Corrosion Performance

   Integrated aluminum frame improves overall structural rigidity, resists long-term vibration from highway driving. Surface anti-rust coating prevents erosion by rain, dust and road salt spray, adapting to global all-climate operation environments. Each unit passes nitrogen high-pressure air tightness test before delivery.

4. Direct Plug-and-Play Replacement

   Overall dimensions, hole positions and pipe connectors fully match original TCH12A specifications. No cutting, drilling or pipeline modification required during installation, greatly shortening overhaul working hours and vehicle downtime.

5. Lightweight High-Capacity Layout

   All-aluminum construction reduces self-weight while maintaining large heat exchange area, perfectly fits the rooftop installation space of 12m large coaches, balancing cooling power and unit load weight.
