Trans/Air Manufacturing Corp. has unveiled a new rooftop unit product line as well as a new climate control system and a stainless steel skirt mount condenser.

The TA17 C-5 Transit Style Climate Control System is designed to meet the requirements of 30-foot to 40-foot rear engine school buses, transit and tour buses in severe-duty applications. When paired with a 655cc transit compressor, the system can yield 111kilowatts (SAE)/171kilowatts (IMACA) BTU/hr, according to the company.

The TA17 evaporator is constructed with heavy-duty materials and has 24-volt heavy-duty motors and large diameter blower wheels mounted outboard to inject air directly into the ducts. The C-5 condenser features five high performance axial fans with a corrosion-resistant coil. Controls are fully functional with digital cabin set point. The 655cc transit style compressor is equipped with an un-loader, transit clutch, and high- and low-pressure switches. The TA17 can be equipped with an optional R120 rooftop condenser, is compatible with all OEM-supplied ducts, and also can be mounted in freeblow configuration.

Additionally, the new TA-20 Rooftop product line features rooftop units characterized by powerful cooling capacity as well as a distinctive aerodynamic design, according to the supplier. Rated at 34K BTU/hr, the TA-20 product line is ideal for a variety of applications, including Type A school buses, small commercial buses, and work vans such as Sprinter, ProMaster and Ford Transit, company officials said.  

The rooftop units feature an aluminum body encased by UV-protected ABS acrylic cover and evaporator blowers oriented to support center aisle ducting or freeblow air distribution with maximum air flow. The TA-20 can be configured as a tie-in or super system and is available with optional heat and electronic controls, according to the supplier.

Meanwhile, Trans/Air also introduced new stainless steel skirt mount condensers. The condensers include corrosion resistant, all-aluminum parallel flow condenser coils, and high-efficiency, low amperage draw condenser fans.

The condensers are now available with stainless steel housing, and the new stainless steel design provides maximum corrosion protection in harsh road environments, company officials said. Stainless steel condensers are available in two (SMC2S) and three (SMC3L) 10-inch fan configurations. Corresponding stainless steel stacking kits are available for applications where skirt mounting space is limited, according to the supplier.
